Abstract：High compression ratio in a hybrid model of three cylinder engine before ignition dual mass flywheel tap on a problem， this article through to the engine combustion data analysis and the double quality flywheel internal centrifugal put on energy analysis， carries on the physical confirmation， eventually improve the ability of centrifugal can put inside rubber suction， effectively solve the problem of dual mass flywheel start hitting the engine， It provides reference for reference and design scheme of centrifugal pendulum dual mass flywheel in hybrid engine with high compression ratio.Keywords： Connecting rod， Fracture， Pressure boosting， Control threshold.

Key words：double-mass flywheel; Start knock; Cylinder pressure; Centrifugal pendulum; rubber
