INTERNAL COMBUSTION ENGINE Russian patent published in 1995 - IPC

FIELD: engine engineering. SUBSTANCE: prechamber with supersonic nozzles, directed along conical surface of the head, is made in the cylinder head. Inlet and outlet openings made in working space of the cylinders are closed and open due to axial movement of the rod with respect to the piston and cylinder sleeve with respect to the cylinder head. Heated fluid is displaced from the cooling jacket and the head to the radiator during moving the cylinder sleeve. Mixture is ignited in response to a signal from a hermetic contact positioned inside the housing of the engine when a permanent magnet interacts with it in the instant of achieving minimum volume of charge of the fuel mixture. EFFECT: decreased wearing away. 3 cl, 2 dwg
