摘要:
为了实现发动机高效清洁燃烧,利用自行开发的可变气门升程机构,在无节气门条件下研究了进气门调整策略(VIV)、排气门调整策略(VEV)和进排气门耦合调整策略(VICE)对发动机性能的影响。结果表明,与原发动机相比,3种气门控制策略都可以降低有效燃油消耗率(BSFC)并提高热效率(ITE);其中,VICE策略的效果最为突出,与原发动机相比BSFC和ITE最多可优化28%和6%;VIV策略和VICE策略都可以减小发动机泵气损失,尤其是VIV策略,与原发动机相比最多可以将泵气损失减少36%;3种策略都可以降低NO x 排放,其中VEV策略表现最优异;当NMEP超过0.3 MPa后,不同气门策略对THC排放的影响较小。
