RV Propane Tips

DOT Cylinders vs. ASME RV Propane Tanks

DOT Cylinder Propane TanksThe primary difference between the two RV propane tanks lies in their placement. DOT cylinders are removable at your convenience. Cylindrically shaped, they appear vertically on the back bumper of towable trailers and campers.

ASME RV Propane TanksThese propane tanks for an RV cannot move from their original spot. ASME RV propane tanks offer a broader range of propane tank sizes. It’s common for singular units to serve as horizontal RV propane tanks. These larger propane tanks do better in mobile homes.

Convenience Comes in All Sizes

The two most common RV propane tank sizes—more relevant to DOT cylinders—are 20 and 33 pounds. If you have a big family, the 33-pound appeals to larger RVs. The 20-pound option offers easier access for those with smaller RVs. You can find these tanks at your local gas station or grocery store.

How to Estimate How Much Propane Your RV Needs

You only need to fill the propane tank for the RV to be 80% full for adequate room for the gas to expand.

Depending on how much propane remains, you need to calculate capacity using the British Thermal Unit (BMU). One gallon of propane is equal to 91,502 BTUs. One pound of propane is equal to 21,548 BTUs. 

Add the demands of appliances you’re using in the RV per hour. Finally, divide the number representing the total BTU by its hourly use.

How Can I Tell The Capacity of My RV’s Tanks?

You can usually just open your tank storage area to see what each tank’s capacity is, but this isn’t always the case.

If the tank capacity isn’t legible on the tank itself, you might be able to find the sizes in your owner’s manual.

Or, you can look up the make, model and year of your RV to find the tank capacity numbers in an internet search.

If you’re buying an RV and want to know the tank sizes, the manufacturer or seller’s website will usually tell you the capacity.

RV manufacturers will sometimes list the capacity of each type of tank individually, and other times they will just note that the water tank size is something like 75-60-50.

This display format is always in reference to your fresh water tank size, followed by the size of your gray water tank and finally, your black water tank.

So in this example, you can carry up to 75 gallons of fresh water, your gray water tank has capacity for up to 60 gallons, and you must empty your black water sewage tank before it reaches 50 gallons full. 

Average gas tank size for Class B RVs

When choosing class B motorhomes, we followed the same logic as with class A motorhomes. We have fewer class B motorhomes on our list, but we still should have enough data for a good general idea of gas tank sizes in class B RVs.

We’ve picked class B motorhomes from Winnebago, Coachmen, American Coach, and Airstream.

Model	GVWR, pounds	Fuel capacity, gallons
WINNEBAGO
Travato	9,350	24
Era	11,030	24.5
Boldt
Revel Diesel	8,550
Paseo	10,360	25
COACHMEN
Galleria Diesel	11,030	24
Beyond	10,360	25
AMERICAN COACH
American Patriot Cruiser Diesel	11,030	24.5
American Patriot Diesel	8,550 – 11,030
AIRSTREAM
Atlas Diesel	11,030	26.4
Interstate Lounge EXT Diesel	24.5
Interstate Grand Tour EXT Diesel
Tommy Bahama Interstate Diesel
Interstate Nineteen Diesel	8,550

Class B motorhomes are the lightest among motorhome classes, with their weight usually being around 10,000 pounds. Generally, class B motorhomes weigh between 10,360 and 11,030 pounds. This is because class B motorhomes are mostly based on the Mercedes-Benz Sprinter chassis. Some class B RVs are based on shorter and lighter variants of the Sprinter chassis.

This also explains why the fuel capacity is very similar in all the models we’ve picked. About 25 gallons may seem very little after the 80-150 gallons of class A motorhomes, but given the weight of class B RVs, 25 gallons is very good fuel capacity.

As we’ve mentioned above, the MPG of class B motorhomes usually is 18-20, which is the highest among all motorhome types. This clearly shows that 25 gallons in class B motorhomes are quite enough.

What we’ve described in our class A motorhome section applies to class B RVs as well. Namely, at a given fuel capacity, a lighter motorhome is going to be more efficient. Class B motorhomes are quite efficient by themselves, but you could get better efficiency by opting for a lighter model.

What Types of Holding Tanks Do RVs Have?

Most RVs and campers have three types of tanks on board:

• Fresh Water tanks that supply water to your sinks, shower(s), and in some cases, your toilet
• Gray Water tanks that hold the dirty water that drains from your sinks and shower(s)
• Black Water tanks that store the sewage from your toilet

It’s smart to empty your gray and black water tanks before they get too close to the full level.

Most RVs come with a sensor that will tell you when it’s getting full, but if you don’t have a sensor in your camper, you’ll need to keep an eye on the gray water tank so you can empty it before it fills up.

I’ll explain how to empty your tanks later in this post.

Mk 3D –

The Israeli Merkava Tank Mk 3D

This vehicle introduced the Mk 3’s ‘forth generation’ armour. Extra armour was added to the chassis, as well as further modules to the turret sides, making them look sloped.

The Mk 3 has also gone through a number of electrical and electronic up-grades to increase crew survivability. The hydraulic turret drive on the Mk 1 & 2 was replaced with an electrical drive on the Mk 3, reducing the number of parts that could explode if struck. A laser warning system, (lasers being used as the targeting system of ATM’s and air-craft) with a threat warning display installed at the commander’s station and manufactured by Amcoram LWS-2, was also installed. The NBC system was also up-graded with the addition of air-conditioning in the BAZ.

An external telephone for supporting troops was also added to the rear of the vehicle so they could communicate with the tank crew.

The BAZ also saw a new advanced fire control system installed called ‘Knight Mk 3’. Manufactured by Electro Optics Industries and Elbit Ltd, it gave the vehicle the ability to engage moving targets while on the move via the use of an automatic target tracker.

The last variant was the Dor-Dalet, which had newly designed tracks (by Israel) and manufactured by the US firm CAT. It also had a small number of improvements being tested for the next Mk in the series.

How Big Are RV Gas Tanks?

Let’s talk size! Depending on various factors, such as the type of the camper, its size and brand, the gas tank sizes will vary a lot. However, the general principle is simple, the bigger the motorhome, the larger the tank will be. So a luxurious class A will grant you with the largest capacity of all other types, which will allow you to refuel it less frequently. On the other hand, a class B and a class C RVs will have a slightly more compact gas tank, giving you a more limited fuel capacity.

Average RV Gas Tank Size Class A

The most luxurious type of RV is the class A type. Naturally, these are the ones that cost the most! This is literally a home away from home and, for this type of RV camper, you should be prepared to spend around $70,000 to $100,000. Their engine is, obviously, extremely powerful, and it’s mounted in the front. As far as the gas tank size goes, class A tanks have the capacity around 80 to 150 gallons. Still, the exact capacity will vary based on the brand, manufacturing year and the size of the RV itself. Overall, Class A motorhomes are extremely expensive, extremely large and that’s why their tanks are way bigger than of any other RV’s.

Bounder RV Gas Tank Size

Fleetwood Bounder is among the top-selling gasoline class A RVs on the road at the moment. Bounder offers comfort and reliability. And it’s a brand that has been connecting families with the great outdoors for a very long time now!

Being a class A, this RV comes with numerous high-quality features that all have one and only purpose — to make you enjoy your travel to the max!

When it comes to the gas tank size of the Bounder, this RV offers an amazing capacity of 80 gallons!

Average RV Gas Tank Size Class B

Class B motorhomes are not as luxurious as class A, which leads to a logical conclusion that their price is also not as high. A regular class B motorhome would cost you somewhere from $35,000 to $75,000. Also, a class B motorhome comes with a freshwater hook up, a sleeping arrangement that’s built on a van and an extension that provides more headroom. The average class B RV gas tank capacity is 25 gallons. So when you compare this capacity to the one of a class A RV, this is way less. In addition to that, as per class A, the manufacturing year and the RV size will also influence the gas tank size.

Average RV Gas Tank Size Class C

A class C motorhome is usually referred to as a “mini-sized” mobile home. Their price is even lower than what you would have to pay for a class B. Basically, they can cost you less than $40,000. A class C would normally come with a cab attached to the motorized RV structured as a van. Essentially, there is not much room for luxury in this type of a camper. And when it comes to the RV gas tank capacity, you’ll have room for 40 to 80 gallons here.

Ford E350 RV Gas Tank Size

This RV belongs to the class C motorhome category. It’s pretty compact, but it still offers a satisfactory gas tank capacity. In fact, its fuel capacity is around 55 to 57 gallons, which is pretty impressive, we must say!

What Size RV Holding Tank Do I Need?

Keep in mind that almost every RV has THREE holding tanks — One to hold fresh water, one that holds toilet sewage, and one that catches drain water.

How much cooking you do, how much water you use, how many people are using the RV… these are all factors to consider when figuring out how large your tanks should be.

It’s entirely possible for a family of four to make it a week on all three tanks IF THEY ARE CONSERVATIVE, minimize their water usage, and don’t have small tanks to start with.

Also, there are ways to dump the waste and refill the fresh water without moving the RV.

But if you have to do so every three days or so, this is a great way to make a relaxing vacation not so relaxing.

How Much Water Do You Need Per Day On The Road?

How much water you will use each day when camping in your motorhome will depend on how many people are in your Rv and the types of daily activities you conduct.

For example, you will need more water if you take many showers or wash dishes or cook often.

On average, you need about one gallon of water per day for fresh drinking water per person. It would be best if you had another gallon of freshwater for cooking, cleaning, and brushing your teeth. Then depending on how often you shower and how long you shower, you might need up to 5 gallons of water per person.

To put it into perspective, a couple can use more than 2,000 gallons of water per month in an average residential home.

However, a couple living in their RV can use 100 gallons of freshwater in nine to 10 days if they are wise about the amount of water they use for various chores and activities.

How Do I Calculate My REAL Gas Mileage?

If you’re trying to figure out the average size of an RV’s gas tank, the next logical question is what kind of gas mileage you can get so you know how far you can go on a tank. We’ve already covered this in a fair amount of detail, but there can be a BIG difference between the gas mileage the manufacturer lists and the real-world mile-per-gallon you get with your RV living full-time on the road.

Usually, the estimate from the dealership or the manufacturer is a bit more optimistic than what you can expect in real driving conditions. That’s because most of the mpg numbers given are under great conditions and perfect load. That just isn’t how the real world works!

So while some modern motorhomes will calculate your MPG for you (right on your dashboard) not all rigs have this. So if you want to get your real-world MPG you’re going to need to do a little math.

I know…but it won’t be hard math!

First, you need to figure out the size of your gas tank. Next, you’ll want to fill your tank to 100% capacity and then write down the current miles on your odometer. Most RVs will have an option to set a trip mile so you could also create a new trip to start from zero.

Finally, you’ll drive until your tank is at the halfway mark and note how many miles you went.

For example, if you’ve got a Class C RV with a tank of 25 gallons and you drive 200 miles on half a tank of gas then your miles-per-gallon is 16. Here’s the formula:

Miles Driven / Gallons of Fuel = MPG

But why are we using the halfway mark of our rig instead of the entire tank?

That’s because we don’t want to actually get our gas tank to empty and it will be hard to know exactly how much gas is left if we’re simply low. The halfway mark is a safe place to stop that can still give us an accurate reading of fuel.

Is That It?

But you’re not quite done. That’s because your average MPG is exactly that…an average! In order to get an accurate number, you’d need to do this dozens of times and take your average rating. It’s further complicated by the type of driving you’re doing. For example, driving 75 mph on the highway for the entire trip will give you a much better MPG rating than stopping and starting across the city or in your campground. That’s why most car manufacturers make a distinction between city and highway miles.

This all seems like a lot of work, right? So why bother figuring this all out?

Why Calculate Your MPG?

The most obvious reason to calculate your MPG is cost-efficiency. If you can increase the fuel efficiency of your RV you can save money!

But there are also some less obvious reasons to track and try to improve your MPG. First, from a planning perspective, you need to know how far you can get on how much fuel. Especially if you’re boondocking and might be traveling far away from a gas station for some time. If you’re just guessing at your typical MPG you could be in big trouble!

Second, I’d argue that improving your MPG can actually improve the safety of your driving! That’s because many of the techniques that can help increase your fuel efficiency are the same techniques that decrease the risks of driving. For example, avoiding rapid acceleration is a great way to improve the fuel efficiency of your RV and a safe driving technique overall.

Average RV Tank Size and Gas Mileage Chart

Contents

RV Class	Gas Tank Size	Miles Per Gallon (MPG)	Distance RV Can Travel on a Single Tank
Class A	80 to 150 Gallons	7 to 13 MPG	560 to 1,950 Miles
Class B	25 Gallons	18 to 25 MPG	450 to 625 Miles
Class C	24 to 55 Gallons	14 to 18 MPG	336 to 990 Miles

The average size of an RV gas tank varies quite a bit, so it can be misleading to make a blanket statement for all RVs. The answer largely depends upon the class of RV.

As you can see in the chart above, in terms of the average tank size, the Class A RV is a clear winner.

Generally speaking, it is the largest RV class on the market, and its size necessitates the larger tank.

Breaking tank size down by class does give us a clearer picture of what we can expect. However, we can do better than that. This is still a low-resolution answer to a question that deserves a high-resolution response.

Fuel Economy Improvements for RVs

Since 2004, fuel economy has improved by a rather dramatic 30%. With such a rapid improvement, it is easy to present information that might be out of date.

We’ve noticed a few out of date posts and wanted to set the records just a bit straighter than they are right now.

The 4 MPG Class A of yesterday is no longer the common story. Yes, you can still find them, but owning an RV has never been more economical.

If you want to read up on these improvements, there is a report available on the Environmental Protection Agency website.

How To Improve Your MPG

Understanding how to improve the MPG of your RV is a big topic! Bigger than this article and you can expect a complete guide to come soon. But for now, take a look at this quick list of tips to improve your gas mileage. You can also try to make a game of it and beat your score! Or if you’re sharing driving responsibilities with someone else you can each try to get the best MPG score!

Here’s the list:

• Watch your tire pressure. Under-inflated tires can really drop your fuel efficiency. In most cases, the ideal tire pressure will be found on the tire.
• Stick with quality motor oil. While it might be tempting to go for the cheap stuff, you’ll pay for it in fuel.
• Don’t overload your RV. Check your owner’s manual to find your cargo capacity and don’t go over. Not only is it dangerous to overload your rig, but it will also drop your fuel efficiency.
• Don’t overhead haul. Carrying equipment on top of your RV can greatly increase drag which will decrease fuel efficiency. You might also run into problems with bridges depending on your RV’s height.
• Avoid stop-and-start driving. While you can’t always prevent stop-and-start driving, you can try to coast as much as possible and avoid slamming the gas!
• Get feedback! In order to figure out how you’re doing, you need feedback in the form of your latest MPG. So make sure you’re regularly tracking your fuel efficiency.

Production and Development

The first M4A2 75 mm (2.95 in) Sherman tank was produced in April 1942, with a new General Motors 6046 engine (two GM 6-71 General Motors Diesel engines), welded hull with extra applique protective armor on the hull sides and gunner position (left side of the turret). In total 8,053 tanks were manufactured by May 1944. Early versions of the M4A2(75) had small hatches and protruding drivers’ and co-drivers’ hoods, a 57 degree glacis and dry ammo stowage bins. The rear hull plate was sloped.
A transitional version built by Fisher, the M4A2(75)D, which had a one-piece 47 degree glacis, with large hatches, but it still used dry ammo bins and applique armor. This model was also produced with a diesel GM 6046, 410 hp, used mostly for the British and the USMC. Range was 241 km (150 mi) with 641 liters (170 gal) of fuel (consumption was 279 liters/100 km or 118.6 gal/mi), total weight 31.8 tons, with a 1.01 kg/cm³ ground pressure. The hull frontal glacis was 108 mm (4.25 in) thick.
The M4A2(76)W was the upgunned late variant, of which over 3230 were delivered by May 1945. It was fitted with the modified T23 turret, which housed the M1 L/55 gun, which gave an overall length of 7.57 m (25 feet). With the GM 6046 diesel, and 673 liters (178 gal) of fuel, range was 161 km (100 mi). The weight rose to 33.3 tons. The glacis was at 47 degrees, 108 mm (4.25 in) thick with large hatches.Canadian M4A2(76)W Sherman tank driving along forest tracks at the Camp Petawawa Training Ground in 1963.

Do People Generally Upgrade The Holding Tanks?

Many motorhome enthusiasts choose to upgrade their holding tanks when they plan on camping off-grid or at campsites with no water, electricity, or sewerage hookups.

However, it is not a simple process as many design features need to be considered, and a professional usually needs to be consulted.

Often a motorhome won’t be able to fit a larger holding tank than what was factory installed. Fortunately, if this is the case, there is a solution. You can upgrade your motorhome holding tanks by taking portable water tanks into your RV for your freshwater tank.

Unfortunately, you cant do the same for your greywater tank or blackwater tank as those are for wastewater.

What Is The Typical RV Holding Tank Size?

What size are RV holding tanks? Is there a typical RV holding tank size?

Though there may be an ‘average’ size for holding tanks on certain RV classes, you should not assume the tank capacity of any of your tanks or ANY RV you are looking to purchase.

There are no ‘average’ sizes of the three tanks. Remember, there are usually three different tanks!

And they rarely are the same size. Every RV has its own configuration, some requiring X gallons of water for drinking and washing, and others having a black water capacity that can suit a family of four.

Typically, the larger the RV, the larger the tanks will be. A smaller travel trailer will have, USUALLY, less tank capacities than a 40′ Class A RV.

The smallest of RV classes, the Class B RV (van), typically has the smallest tanks. The ‘Class A’ motorhome tends to have the largest sized tanks.

Sometimes RVs even have two black water tanks or grey water tanks.

Suppose you are ever camping without connections to water and a sewer. In that case, it’s best to have a general idea of your RV water tank size and its waste tank sizes and know how long you can go without having to dump (draining your waste using a camper septic hose) or refill.

What’s The Biggest RV Gas Tank Size?

As I’ve mentioned a few times, the size of RV gas tanks can vary quite a lot between the different classes, models, and overall varied types of RVs. Although most rigs will have a gas tank size between 25 and 100 gallons, some big Class As may have a gas tank able to hold 150 gallons! Now that’s a number suited to some mighty road trips!

Most RVs won’t even come close to this number, but if you have the budget required to purchase a luxury Class A rig, you can expect to be powered on the road for a considerable amount of time. Just remember to stay safe on the road, and only drive a sensible number of miles each trip to avoid accidents and exhaustion! 

Характеристики и принцип работы

Tank avg Lexus — это технология, разработанная компанией Lexus, которая позволяет автомобилю двигаться с использованием двух различных источников энергии: бензинового двигателя и электрического двигателя. Это смешанная система питания, которая обеспечивает более эффективное использование топлива и повышенную экономичность автомобиля.

Принцип работы Tank avg Lexus основан на том, что электромотор в автомобиле работает совместно с бензиновым двигателем, но вместо полного использования топлива, как в обычном автомобиле, здесь происходит оптимизация его использования. Электромотор помогает снизить нагрузку на бензиновый двигатель, особенно во время активного разгона и низких скоростей.

Когда автомобиль стоит на месте или движется со скоростью ниже определенного уровня, электромотор питается от литий-ионной батареи, которая заряжается во время движения и регенерации энергии при торможении. Это позволяет снизить выбросы экологически вредных веществ и снизить расход топлива.

Когда водитель нажимает на педаль акселератора или требуется большая мощность, бензиновый двигатель включается и работает параллельно с электромотором, обеспечивая нужную мощность и скорость. При этом электромотор также может работать в режиме генератора и заряжать батарею.

Эта технология позволяет автомобилю Lexus улучшить его экономичность и снизить выбросы CO2, что делает его более дружественным к окружающей среде. Кроме того, система смешанного питания позволяет автомобилю работать тише и плавнее, повышая комфорт и удовольствие от вождения.

Характеристики:

• Мощность двигателей — бензинового и электрического;
• Батарея — литий-ионная;
• Регенеративная система зарядки;
• Электромотор работает параллельно с бензиновым двигателем;
• Снижение выбросов CO2;
• Увеличение экономичности и эффективности использования топлива.

Технология Tank avg Lexus является инновационной разработкой в автомобильной индустрии и является одним из способов создания более экологичных и эффективных автомобилей, сочетающих в себе два различных типа энергии.

M4A2(76)W with HVSS Sherman tank

Many people call this tank the M4A2E8 -The Easy 8. The designations M4E8, M4A1E8, M4A2E8 or M4A3E8 only officially applied to prototype vehicles used to test the new HVSS (Horizontal Volute Spring System) suspension. Its experimental E8 designation led to the ‘Easy Eight’ nickname for Sherman’s so equipped. Many websites say it was because this tank was powered by a V8 engine. This is wrong. Not all the Sherman tanks given this experimental designation were powered by V8 engines.
The experimental code E8 refers to a tank fitted with Horizontal Volute Spring Suspension (HVSS) system, with wider tracks. The only production Sherman tank that had an official E designation was the up-armoured 75mm Gun Tank M4A3E2(W) – the so called Jumbo. In the American army in the 1940’s, the letter E in the phonetical alphabet was known as ‘Easy’.
The U.S. adopted the Joint Army/Navy Phonetic Alphabet during 1941 to standardize systems among all branches of its armed forces. The U.S. alphabet became known as Able Baker after the words for A and B. Today, the 1951 International Radiotelephony Spelling Alphabet, commonly known as the NATO phonetic alphabet, uses the word ‘Echo’ when referring to the letter E. To complicate the naming issue, some Canadian Army documents name this tank by its prototype name, the M4A2E8.
The ‘E8’ HVSS suspension modification was an effort to improve the ride and increase the mobility of the Sherman tanks that had progressively become heavier with increased armor and a bigger 76 mm (3 in) gun. The HVSS system used four wheels per bogie instead of two, which allowed tracks that were wider to be installed: 23 inches (58.42cm) compared to the normal 16 inches (40.66cm).  It did give better performance on soft ground and allowed for a smoother ride.Royal Canadian Armoured Corps (RCAC) M4A2(76)W HVSS Sherman Tanks of the Essex Regiment (Tank), (Windosr Regiment) 30th (Reserve) Reconnaissance Battalion

Types of RV Propane Tanks

There are two main types of RV propane tanks, ASME tanks, and DOT cylinders. Most RV motorhomes will possess an ASME tank while travel trailers and RVs that are towed will more likely have a DOT cylinder.

What is an ASME tank?

The most common type of motorhome propane tank, an ASME tank is usually non-removable and mounted to the outside of your RV. To refill your ASME tank when you’ve run out of propane, you will need to go to a refilling station that is specifically for RVs. ASME tanks may vary greatly in size and storage capacity. As they are non-removable, make sure that you get a motorhome with a good-sized tank to meet all of your needs.

What is a DOT Cylinder?

In general, DOT cylinders are smaller than ASME tanks and are found on towed motorhomes such as travel trailers. Contrary to ASME tanks, DOT cylinders are not stationary and can be removed from your travel trailer when needed, this makes refilling more convenient.

The Different Types Of Holding Tanks

Before we can look at the different RV holding tank sizes equipped in the different motorhome classes, it’s important first to understand what the various holding tanks are in your RV.

Below we have explained the three different types of holding tanks that you will find in your motorhome.

Freshwater Holding Tank

The freshwater holding tank is the tank that holds your freshwater or drinking water.

It is also the water that you will use to wash your dishes and that you will use to bathe with. The more people you are accommodating in your RV, the larger your freshwater holding tank needs to be.

Grey Water Holding Tank

Your grey water tank is where all your wastewater from your shower, bathroom sinks, and kitchen sink goes.

This water travels through your motorhomes plumbing system and is separated into the grey water tank. Often the grey water tank will also contain food particles and soap residue.

If you are only a solo traveler or are traveling with one other person, you don’t need a greywater holding tank that is overly large, especially if you will have frequent access to dump stations.

Blackwater Holding Tank

The holding tank that most motorhome enthusiasts hate to learn about is the blackwater holding tank.

This holding tank is where the wastewater from your toilet is stored. Special precautions need to be taken when you empty your black water holding tanks.

You’ll need a bigger blackwater holding tan when you have more people in your motorhome.

QJT5.8mm coaxial machine gun (latest upgrade)

QJT5.8mm coaxial machine gun

Type 99 tankAs the most advanced familytankNaturally, it is equipped with the same advanced foreign tanks.Coaxial machine gun. The role of the coaxial machine gun is to give the tank a strong suppression of the infantry. And with the captainmachine gunDifferently, the coaxial machine gun can be operated inside the turret to ensure the safety of personnel.

The coaxial machine gun used before was 86 Universal machine gun. This universal machine gun comes from the 80-type universal machine gun, and this gun can be said to be the most comprehensive general-purpose machine gun used so far. It was a generic machine gun designed and produced by the famous Soviet PKM/PKMS general machine gun, which was seized and has a caliber of 7.62 mm. This machine gun has the advantages of light weight, high reliability, high precision and compact structure. However, when competing with the 67 series machine gun for the company’s general-purpose machine gun, it was defeated by the 67-2 general-purpose machine gun for other reasons, and it became another type of machine (such as the 86-type coaxial machine gun that became a tank after foreign trade and modification).

It is understood that many advanced tanks no longer use the 80-type universal machine gun as a coaxial machine gun. Instead, use a 5.8 mm coaxial machine gun. The new machine gun is temporarily named QJT5.8mm coaxial machine gun. It is understood that this machine gun is based on the improvement of the 88-type universal machine gun, which was exposed at the beginning of this century. In recent years, this coaxial machine gun can be said to be truly implemented in the newly produced armored vehicles. For example, the coaxial machine gun on the latest 99A main battle tank is this weapon. Although the caliber of the QJT5.8mm coaxial machine gun has been reduced, it also has many advantages.

Compared with the 86 type, this coaxial machine gun has the advantages of more compact structure, higher bullet versatility, more bomb-loading capacity, faster firing rate, and similar bullet performance at 800 meters compared with the original 7.62 machine gun. However, this machine gun and the 88 type Universal machine gun. Similarly, when the enemy distance is greater than 800 meters, the shooting effect is not as good as the medium caliber machine gun. However, for a tank, since there is a 125mm smoothbore gun and a 12.7 machine gun, the response to an enemy greater than 800 meters is naturally not required to be responsible for the coaxial machine gun. Small caliber Coaxial machine gun. A series of advantages that are very suitable tank. Other subsystems are designed to meet their combat responsibilities and logistics. Therefore, the QJT5.8mm machine gun eventually replaced the 86 type.machine gun. Translated by google – Source pixpo.net

Two five-barrelled smoke grenade launchers are on each side of the turret. By injecting diesel fuel into the engine’s exhaust, additional smoke is also generated.
