KamAZ trucks began to be built in 1969. For a new generation of trucks, engineers created a 4-stroke diesel 8-cylinder KamAZ-740 V8 engine. This power unit had a working volume of 10852 cm3, and its power was 210 horsepower. Then, the power indicators had to be expanded from 180 to 360 hp. The motor has relatively small dimensions, and also has a lower mass in comparison with the same YaMZ-238.
Torque from the motor to the main components is transmitted through spur gears. So, the gears of the gas distribution system, pumps and compressors, as well as the hydraulic booster work on the gears. The KamAZ-740 engine has a good start even at very low ambient temperatures. This was made possible thanks to the power of the battery, starter and heater units before starting.
