The Chelyabinsk Tractor Plant, in particular its Head Special Engineering Department "Transdiesel", gained wide experience concerning production of the special purpose diesel engines.

  A number of foreign countries took up the production licenses on the diesel engines В-46 and В-84 applied in the power plants designed for the tanks Т-72. In 1999, in Chelyabinsk Tractor Plant the development of new tank diesel engine В-92С2 of 1000 hp was completed. It went through all possible tests including the state ones.

  In June - July of 1999, in India this diesel engine was successfully tested on the tanks Т-90С to win the contract. The tests were carried out under the hardest desert conditions at high dustiness level at the ambient temperature up to plus 47 °С. This diesel engine proved not only its high reliability but also its high traction performance quality.

	Torque backup, %	25...30
	Overall dimensions, LxBxH, mm	1466х896х902
	Weight, kg	1020

 The Plant develops the engines more promising for the next-generation machines. But to improve the tanks Т-72, the diesel engine В-92С2 is obviously beyond comparison. Its installation requires minimal re-equipment of the motor-transmission compartment and minimal financial expenditure. The diesel engine В-92С2 equipped with the gas-and-turbine supercharging as well as with the improved fuel facilities and cylinder-piston set, comes up to the level of the best world models. As per its economy capacities and specific weight-and-dimensional rate the diesel engine transcends the most of both domestic and foreign engines.

 The weight of the diesel engine В-92С2 is only 1020 kg: that is less for more than twice if compared to the weights of the diesel engines AVDS-1790 (USA), C12V (England), UDV-12-1100 (France). The overall capacity of the diesel engine В-92С2 exceeds theirs for 1.5 - 4.5 times, its fuel efficiency under working conditions is more for 5 - 25%.

 The torque backup is also noteworthy. The torque backup of the most diesel engines is 6 - 18%, as for the diesel engine В-92С2 - 25 - 30%. Such torque backup makes the tank control much easier, increases its maneuverability and mean speed.

 The moderate overload of diesel engine В-92С2 by its power-per-liter gives the high reliability at hard usage. Without any doubt the diesel engine В-92С2 will be sold readily.
