The Russian tank fleet incorporates a range of diesel engines, with different models and configurations.
One prominent engine used in Russian tanks is the V-92S2, which powers the T-72B3 and T-90 tanks. This engine is a V-12, liquid-cooled, four-stroke diesel engine. It has a displacement of 38.9 liters and produces a maximum power output of around 1,000 horsepower. The V-92S2 is renowned for its exceptional reliability and efficiency, allowing tanks to operate efficiently even in challenging conditions.
Another notable engine utilized in Russian tanks is the 12-cylinder, multi-fuel, liquid-cooled diesel engine designated as the 2A46. It is employed in the T-80 series of tanks, including the T-80U and T-80UD. The 2A46 engine has a displacement of 38.8 liters and generates a maximum power output of approximately 1,250 horsepower. This engine offers remarkable power-to-weight ratio, enabling the tanks to achieve high speeds on various terrains.
The T-14 Armata, Russia's most advanced main battle tank, incorporates a unique engine known as the A-85-3A. It is a 12-cylinder, multi-fuel, four-stroke diesel engine. The A-85-3A has a displacement of 1,000 cubic inches (16.4 liters) and provides a maximum power output of around 1,500 horsepower. This engine is notable for its modular design, which facilitates easy maintenance and replacement of components, reducing downtime and enhancing the tank's operational readiness.
In addition to these engines, Russia has also developed diesel engines for other armored vehicles. For instance, the BTR-82A, an amphibious armored personnel carrier, is equipped with a YaMZ-5347-10 diesel engine.
This 4-stroke, 6-cylinder engine has a displacement of 7.7 liters and delivers a maximum power output of approximately 300 horsepower. The YaMZ-5347-10 is lauded for its reliability and fuel efficiency, ensuring the BTR-82A can operate effectively in diverse environments.
Russian tank diesel engines are designed to withstand extreme conditions and provide high torque at low RPMs, making them suitable for heavy armored vehicles. They are often equipped with advanced cooling systems, turbochargers, and fuel injection technologies to optimize performance and fuel efficiency. Additionally, these engines are typically compatible with various types of fuel, including diesel, kerosene, and gasoline, providing flexibility in operation and logistics.
