FIELD: engines and pumps. ^ SUBSTANCE: power conversion is performed inside sole cylinder divided into pressure chamber wherein compressed gas is fed from low-pressure line in operating conditions of compressor, and combustion chamber wherein, at the same conditions, air is fed and fuel is fed from pressure chamber. Thermal power produced in combustion chamber is converted into potential power of gas from pressure chamber. Note here that, in expansion stroke, portion of compressed gas potential power is fed into high-pressure line and remaining potential power is used for operation in engine operating conditions. Changing into engine operating conditions is performed by switching air feed into pressure chamber and fuel feed I switched over into combustion chamber. Said method may be implemented in piston-type compressor. Compressor cylinder accommodates extra piston coupled with compressor shaft to divide compressor chamber into pressure and combustion chambers, thrust to limit extra piston travel, fuel feed line and control valve to feed fuel from pressure chamber into combustion chamber, exhaust gas release valve and air feed valve. In this case combustion chamber runs like it does in piston ICE. Thermal power is used for making rotating moment and for compressing and feeding the gas into high-pressured line. To switch from compressor into engine operating conditions, there are valves to change over from gas fuel feed to air into pressure chamber and from air to fuel into combustion chamber. ^ EFFECT: reduced power losses and weight, improved operating performances. ^ 4 cl, 2 dwg |
