How is a tank engine different from a car

The debate about whether modern main battle tanks will be powered by diesel engines or gas turbines has long been debated, but in the end there is no one conclusion. At present, except for the American "Abrams" and Russia's T-80U main battle tanks, which use gas turbines, the vast majority of other main battle tanks still use diesel engines. However, the development of gas turbines remains strong.

Russia is not only equipped with T-80U main battle tanks equipped with gas turbines, but also has developed a series of gas turbines, such as the GTD-1000, GTD-1250 and GDT-1500. Russian gas turbine expert Valery Morozov believes that gas turbines are superior to diesel engines in many ways: first, it takes only 1 minute to start a gas turbine, while to start a diesel engine it first has to be warmed up, and then according to convention, it takes another 30 minutes to start; second, the gas turbine does not stall when the vehicle is driving in the mud, or when passing through vertical obstacles, which is not possible with a diesel engine; Thirdly, the speed of the T-80U tank with a gas turbine is 10 kilometers an hour higher than that of the T-90 tank, which is very advantageous for the tank on the battlefield; Fourth, gas turbines do not require radiators, water, antifreeze or other coolants, thus eliminating the need for bulky and complex coolant supplies.

Gas turbines have a longer service life than diesel engines, and their wear resistance is twice or even three times that of diesel engines. To sum up, the gas turbine is simpler to operate and easy to maintain, and it only takes 4 hours to overhaul 1 gas turbine, while it takes 24 hours to overhaul 1 diesel engine.

Although the fuel consumption of a gas turbine is about 20%-30% higher than that of a diesel engine, when the vehicle is stopped, the gas turbine is turned off and the auxiliary power unit supplies power to the vehicle, thereby saving fuel. Gas turbines do not consume lubricants when they work, and the gas burns sufficiently, so the exhaust gases are clean and do not pollute the environment. In Russia, gas turbines also have a higher power output than diesel engines, up to 250 horsepower.

Everyone knows that the power of the tank is very strong, so what is the structural difference between its engine and the gasoline engine? Below there is a foreigner disassembling a tank engine that has been in ash for more than 25 years, and we can just get a glimpse of it.

Some tanks have 8 cylinders, and Mercedes Benz has 12 cylinders.

Chinese tanks basically use diesel engines, which are powerful and fuel-efficient.

American tanks have gasoline engines with high maximum cross-country speeds.

Ordinary vehicles use gasoline engines, *** also use gasoline engines, and tractors use diesel engines.

More horsepower, more fuel consumption, heavier engine mass, more durable.

The engine of the tank is more powerful and consumes more fuel.

Such a simple question. The tank's engine needs to work in extreme environments, even under artillery fire. This is the most fundamental difference. Think for yourself about the other differences.

That's absolutely different, tanks are for the needs of war, and ordinary cars are different.

Is this dragging? Yesterday's know**, see for yourself.

Tank engines are usually characterized by high horsepower, high structural strength, and water cooling and heat dissipation!

The T-72 tank, for example, used a 780-horsepower V12 diesel turbocharged engine, which was officially installed in 1939. In many technologies, it is no different from the current diesel engine, and it also adopts a water-cooled heat dissipation system, which is completely consistent with the civilian diesel engine. Of course, given the age of development of this engine, it does not have the high-pressure common rail fuel supply system found in today's diesel engines, but instead uses a mechanical fuel supply system that is not easily damaged and easy to repair.

It can be said that the biggest difference between the engine of the T-72 and today's civilian diesel engines lies in the degree of electrification.

The engine of the T80 tank is the engine of ***, so it is added with aviation kerosene.

The types of modern tank engines are:

Tank diesel engine: Since May 1954, when the Su-34 medium tank first used a high-power diesel engine, the vast majority of modern tanks use high-speed diesel engines, and few gasoline engines have been used. This is a good economy for diesel engines, that is, in the case of carrying the same capacity of fuel, the maximum stroke of a diesel engine with the same power is twice that of a gasoline engine.

Moreover, on the battlefield, diesel engines and gasoline engines are not easy and safer. According to statistics, modern tank diesel engines are mostly multi-cylinder), V-shaped (the angle between the two rows of cylinders is °) up-stroke diesel engines (there are also opposing two-strokes). According to its cooling method, there are two kinds of tank diesel engines: water-cooled and air-cooled.

Gas Turbines: Although the application of gas turbines to tanks has been studied for decades, only the M-1 main battle tank in the United States has officially adopted it as a power plant for main battle tanks.

Twin power units: On the Swedish S tank, a dual power plant with a counter-piston two-stroke water-cooled diesel engine and a gas turbine in parallel was used.

The vast majority of modern tanks are diesel, with only the early models of the Maozi T80 and the M1 series in the United States using gas turbines. The gas turbine here is indeed derived from aviation power technology, but it is already a system of vehicle stuff that is decelerated by the output of the turbine shaft through the gears.

Generally, it is a turbocharged multi-cylinder high-power diesel engine, with a power of 1000 to 1500 horsepower and a volume of about cubic meters. Germany's Leopard II series, Britain's Challenger II series, China's 99 series, 96 series, 59-69 series, Soviet Russia's T-72 series T-90 series, Israel's Merkava series, etc., all use diesel engines.

There are also gas turbines, such as the T-80 of Soviet Russia and the M-1 Abrams of the United States, the power is almost around 1500 horsepower, but the volume is much smaller, and the fuel is not picked, diesel and kerosene can be burned, but it is too oil-intensive, and the maintenance in dusty areas is also particularly troublesome, and the pressure on logistics is very great, so other countries rarely use it.

Heavy tanks generally refer to tanks of more than 40 tons That was the division of the Second World War According to the tonnage Before the 60s of the 20th century, tanks were mostly divided into light, medium, and heavy according to the full combat weight and the caliber of artillery. Heavy tanks usually weigh 40 to 60 tons, and the caliber of the gun is up to 122 mm, which is mainly used to support medium tank combat. It is characterized by a large caliber of artillery, a long barrel and a large attack power.

Because the caliber of tank artillery is large, which means that the attack power is large. There are several types of heavy tank guns with calibers of 90 mm, 100 mm, and 125 mm. At the same time, the heavy tank has thick hull armor and strong resistance to shelling.

After World War II, a number of new battle tanks appeared, whose firepower and protection capabilities reached or surpassed those of the previous heavy tanks, and overcame the shortcomings of heavy tanks with poor mobility and stronger battlefield adaptability. Therefore, since the 60s of the 20th century, countries have reclassified the original light, medium and heavy tanks. The new type of battle tank in the medium and heavy tanks is called the main battle tank.

The main battle tank doesn't have to be a heavy tank!

<> "Why do most tank engines choose rear?

The main battle tanks of all countries in the world basically adopt the design of the rear engine, which is very beneficial to the protection and mobility of the tank. After World War II, countries around the world gradually adopted this design.

For the tank **, a reasonable spatial structure layout is very important for the combat effectiveness of the tank. There are a number of advantages to using a rear engine over a front-engine Plex Resistant. First of all, the frontal armor of the tank is very important in battle.

After all, the front of the tank is the main battlefield, and the thickness of the armor on the front is often the strongest. The increase in thickness usually takes up a certain amount of space on the front.

If the engine is arranged in front, it affects the layout of the tank turret. Either increase the height of the turret to accommodate the front-mounted engine, or place the turret back to the shote Sakura. The increased height significantly increases the risk of exposure of the tank, and the fragile turret is more vulnerable to attack.

However, the turret will expose more of the front of the hull, require more armor protection, and will have more limited space, thus entering a vicious circle. Obviously, the rear engine has more advantages than the front engine.

Secondly, the rear engine can improve the mobility of the tank, balance the structural weight of the tank, and ensure the mobility of the tank.

Because the front armor of the tank is thicker, the overall weight of the tank is naturally higher, and if you add the engine, the weight of the tank will be heavier. When climbing hills or driving off-road, the heavy nose reduces the cross-country ability and maneuverability of the tank.

At the same time, the heavy-headed, light-tailed structure of the potato wheel will also disrupt the structural balance of the tank. In order to maintain balance, it was necessary to increase the weight of the tail section, which led to an increase in the overall weight of the tank and a decrease in maneuverability.

In addition, the rear of the engine is also conducive to the maintenance of the fuel tank, and the optimization of the internal space is more reasonable. Due to the frequent maintenance of tank engines, it is necessary to reserve a large number of inspection openings or hatches. Due to the limited space in the front of the tank, it is necessary to set up a turret observation hole, which is not conducive to the maintenance of the tank.

The rear-mounted engine makes full use of the space behind the fuel tank and simplifies maintenance operations. At the same time, it is also conducive to the layout of the transmission system, which only needs to be integrated and installed with the engine, which is more convenient for maintenance and repair.

Due to the superiority of the rear engine, the design of the full engine was gradually phased out in the tank. However, the forward engine had certain advantages in terms of crew protection. When shelled attacked, the engine became a double layer of protection in addition to the front armor, which effectively protected the crew from injury.

In a country like Israel, where tank protection is emphasized, the safety of the crew is more important than the tank, so Israel's Mejiawa tank has a comprehensive engine design. For countries that emphasize the assault operations of tank groups, the rear engine is clearly more advantageous.
