HYDROPNEUMATIC INTERNAL COMBUSTION ENGINE Russian patent published in 2022 - IPC F02B71/04 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to the field of mechanical engineering. A hydropneumatic internal combustion engine is proposed, to the body 5 of which a compressor cover 4 is attached from below with an outlet valve 1 of the compressor and an inlet valve 2 of the compressor. Inside the housing 1 there is a cylinder 8 and a sleeve 45. An electromagnetic latch 10 is installed in the housing 1. A spring 18 is located between the cover 4 of the housing and the cover 15 of the cylinder. The valve 17 inlet and the exhaust valve 19 enter into the cover 15 of the cylinder. The piston 13 is located in the cylinder 8, rod 12, hydraulic piston 11, compressor piston 9, compressor spring 7. The cooling motor pump 25 is controlled by an electromagnetic cooling valve 30. The hydraulic motor-generator 28 is controlled by the electromagnetic valve 29 of the generator. The electromagnetic injector is connected by a pipeline to the body of the hydraulic accumulator 36 of the fuel. The body of the hydraulic accumulator 36 of the fuel is connected by pipelines with the electromagnetic return valve 32, the throttle 33 and the hydraulic motor-pump 34 of the fuel with the electromagnetic fuel valve 31 attached to it. The hydraulic motor-pump 34 of the fuel through the solenoid valve 40 flow through the pipeline communicates with the housing 41 of the accumulator. The body 41 of the accumulator through the electromagnetic pressure relief valve 35 communicates with the tank 27 by a pipeline. The control elements of the internal combustion hydropneumatic motor are connected by wires to the control and signaling unit 56.

EFFECT: use of a hydropneumatic internal combustion engine will reduce the energy costs for the drive of the running gear, working bodies and elements of the control systems of technical means.
