FIELD: engines and pumps.
SUBSTANCE: internal combustion engine (ICE) with split cycle includes crankshaft (52), compression (66) and expansion (68) cylinders, compression (72) and expansion (74) pistons, and spiral bypass channel (38). Compression piston (72) performs inlet and compression strokes per one turn of crankshaft (52). Expansion piston (74) performs expansion and outlet strokes per one turn of crankshaft (52). Spiral bypass channel (38) connects compression (66) and expansion (68) cylinders. Spiral bypass channel (38) includes bypass compression and expansion (41) valves, straight-line (39) and end (40) parts. High pressure cavity is made between bypass valves. Expansion bypass valve (41) includes stock (42) and head (43). Straight-line part (39) is located in end section of spiral bypass valve (38). Spiral end part (44) is an integral part of straight-line part (39). Spiral end part (40) is located above bypass expansion valve (41). Spiral end part (40) represents funnel (44). Funnel (44) is twisted about stock (42). Also, the invention deals with ICE containing two tangential spiral bypass channels (78). Channels (78) connect compression (66) and expansion (68) cylinders. Each tangential spiral bypass channel includes bypass valves (84, 86), straight-line tangential part (100) and spiral end part (102). Spiral end parts (102) are twisted in one direction.
EFFECT: quick flow of flammable mixture, its quick mixing and distribution prior to the beginning of combustion.
