摘 要：針對某混動車型高壓縮比三缸發(fā)動機在點火前雙質(zhì)量飛輪敲擊問題，本文通過對發(fā)動機燃燒數(shù)據(jù)分析及雙質(zhì)量飛輪內(nèi)部離心擺敲擊能量分析，進行實物確認，最終提高離心擺內(nèi)部橡膠吸能能力，有效地解決了發(fā)動機雙質(zhì)量飛輪啟動敲擊的問題，為匹配離心擺雙質(zhì)量飛輪在高壓縮比混動發(fā)動機上的引用及設(shè)計方案提供參考。

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
