METHOD TO PROVIDE WORKING PROCESSES IN INTERNAL COMBUSTION ENGINES Russian patent published in 1999 - IPC

FIELD: mechanical engineering; four-stroke internal combustion engines. SUBSTANCE: method comes to intake of fresh charge of working medium into cyclically changing working volume of engine, compression, ignition and combustion of working mixture with subsequent expansion of working medium and exhaust of gases. After intake and before compression charge is expanded during one stroke of charge of engine volume from minimum to maximum value. EFFECT: increased efficiency of engine, reduced noise and liberation of heat. 2 cl, 1 tbl, 3 dwg
