Abstract: There exists the phenomenon of intermittent vehicle idle shake during vehicle development,which seriously affects driving comfort.Through testing and analyzing parameters such as vibration characteristics,purge solenoid operating frequency,engine cylinder pressure,intake pressure,and powertrain rigid body modes,the authors identify the root cause of the problem and propose corrective measures.After optimization,the intermittent shaking phenomenon improved markedly.
Key words: intermittent idle shake; purge solenoid operating frequency; powertrain rigid body mode
