FIELD: engines and pumps.SUBSTANCE: invention can be used in internal combustion engines. Engine (10) comprises crankshaft (16), compression piston (20) fitted in compression cylinder (12), expansion piston (30) fitted in expansion cylinder (14) and adapter channel (22). Compression piston (20) reciprocates at intake and compression strokes at one revolution of crankshaft (16). Expansion piston (30) reciprocates at expansion and discharge strokes at one revolution of crankshaft (16). Adapter channel (22) communicates compression and expansion cylinders (12), (14) and comprises expansion valve (26). Engine (10) runs in ignition mode (EF mode) and features residual expansion at closure of valve (26) making 10 to 1, or higher. Invention discloses the engine operation.EFFECT: decreased harmful emissions.12 cl, 14 dwg |
