FIELD: mechanical engineering.
SUBSTANCE: invention relates to internal combustion engines with divided cycle. Proposed engine 100 has crankshaft 108 rotating relative to axis of crankshaft 110 of engine 100. Expansion piston 114 is fitted for sliding into expansion cylinder 104 and is connected with crankshaft 208 so that expansion piston 114 reciprocates during working stroke and exhaust stroke of four-stroke cycle at one revolution of crankshaft 108. Compression piston 116 is fitted for sliding into compression cylinder 106 and is connected with crankshaft 108 so that compression piston 116 reciprocates during intake and compression strokes of the same four-stroke cycle at the same revolution of crankshaft 108. ratio of cylinder capacities from BDC to TDC for any one expansion cylinder 104 and compression cylinder 106 is 40:1 or greater. Invention contains description of method of combustion of gas in this engine.
EFFECT: improved operation reliability.
