INTERNAL COMBUSTION ENGINE AND METHOD OF ITS OPERATION Russian patent published in 1997 - IPC

FIELD: mechanical engineering; internal combustion engines. SUBSTANCE: exhaust system of internal combustion engine makes it possible to match the location of exhaust ports and remaining gases suction ports with operation of engine. Used gases under pressure in working chamber are forced out from space at exhaust stroke onto active nozzle of ejector communicating, through passive nozzle, with remaining gas suction port of preceding working chamber in which suction stroke takes place at this moment, thus cleaning the space from remaining gases. Working member of combustion chamber moving in the space serves to overlap exhaust ports. EFFECT: improved reliability of operation. 2 cl, 4 dwg
