FIELD: engine devices and pumps.
SUBSTANCE: SUBSTANCE when temperature of the pistons, rods and cylinder of the engine is above optimal, a control system switches an air feed valve to open position. The air compressed in the compressor cavities enters the turbine and is discharged into the atmosphere. The turbine drives a cooling liquid pump and a fan. The cooling liquid pump pumps cooling liquid through the channel of the piston group and through space between engine cylinder and its jacket. The radiator is blown by the fan. As a result, the heat from the piston group and the engine cylinder is discharged through the radiator to the atmosphere. The control system of the temperature sensor of the cooling liquid controls the temperature of the cooling liquid and, when it is lowered, closes the air supply valve.
EFFECT: increased cooling efficiency of the pistons and rods.
