FIELD: engines and pumps. ^ SUBSTANCE: proposed device is used to control ICE with universal valve system and compression ratio control mechanism to control compression ratio in combustion chamber. It controls lift adjustment and compression ratio control mechanisms so that, in increasing required engine power output, compression ratio decrease rate is lower that lift increase rate, while in decreasing required power output, lift decrease rate exceeds compression ratio increase rate. In case engine comprises additional valve phase control mechanism to regulate valve phase, then proposed device controls compression ratio control mechanism and phase control mechanism so that, in increasing required engine power output, compression ratio increase rate increases phase lagging rate, while in decreasing power output phase advance rate exceeds compression ratio increase rate. ^ EFFECT: ruling out collision between valve and piston. ^ 30 cl, 25 dwg |
