摘要
In order to investigate the torsional vibration characteristics of the variable displacement diesel engine and explore the best variable displacement schemes, a co-simulation model of a V6 diesel engine crankshaft system is built by using GT-SUITE software and validated by experiments. Various displacement schemes under 10%~50% of engine load are simulated respectively. The results indicate that the torsional vibration angle displacement amplitude of crankshaft under cylinder deactivation increases greatly, which mainly consists of low order rolling vibrations; the fuel cut-off scheme is better than the valve cut-off scheme with the same cylinder deactivation numbers, while the additional torsional vibration stress is slightly larger than the latter's. The fuel cut-off scheme with uniform firing interval has the best torsional vibrational performance.
