FIELD: engines and pumps.SUBSTANCE: two stroke engine with offset crank gear comprises two cylinders 1, 2 with common combustion chamber 3 and one crankshaft 6. Valve-free engine features straight-flow blowing and charging cylinders with air (mix) at pressure above barometric. Piston 7 in cylinder 1 leads piston 8 in cylinder 2 which lags. Axes of cylinders 1, 2 are turned in parallel planes to align TDCs of pistons 7, 8 in said planes. To create delay (advance) angles between pistons 7, 8 in cylinders 1, 2 with common combustion chamber 3 cylinder 2 has piston 8 with offset crank gear.EFFECT: increased power per unit weight.3 dwg |
