FIELD: engines and pumps.
SUBSTANCE: proposed ICE comprises housing, valve gear and fuel feed mechanism, pairs of cylinders with combustion chambers and opposed pistons coupled by common con rod and mechanism to convert piston reciprocation in crankshaft rotation. Said mechanism to convert piston reciprocation in crankshaft rotation is made of drum with closed curvilinear groove. The latter is articulated with piston con rods and fixed grooves made in aforesaid housing. Cylinder with pistons and con rods are arranged around said drum. Engine is furnished with cam plates to open and close intake and discharge valves, hollow shaft to drive said cam plates coupled with aforesaid drum, p.t.o.-shaft with two couplings and gearing to transmit drum rotation to said p.t.o.-shaft. Note here that the latter is arranged inside hollow shaft to drive said cam plates.
EFFECT: higher uniformity of torque, reduced load to con rod, smaller overall dimensions.
