FIELD: engines and pumps. ^ SUBSTANCE: four-stroke ICE incorporates main cylinder with piston, con-rod gear, intake branch pipe with the valve, exhaust manifold with the valve, devices to prepare and to ignite the gas mixture, device to inject water in the cylinder. At that the aforesaid engine comprises an additional cylinder with the piston, its diameter exceeding that of the main cylinder piston, an additional intake and discharge branch pipe with the valve. At that the aforesaid additional intake branch pipe communicates with the main cylinder exhaust manifold, while its exhaust branch pipe communicates with the exhaust pipe. The additional cylinder piston and exhaust valve are linked to the con-rod gear, the additional cylinder piston reciprocating in phase opposition relative to the main cylinder piston and the exhaust branch pipe valve opening with the additional cylinder piston traveling from the DBP to DTP. Note here that the water is injected into the main cylinder during the main cylinder exhaust stroke. The proposed engine comprises an even number of the main cylinders, each pair incorporating one additional cylinder. ^ EFFECT: higher engine efficiency. ^ 2 cl, 1 dwg |
