摘要
在匹配N1类整车的国Ⅳ排放开发过程中,对轻型柴油机的标定策略和燃油控制参数进行了相关的研究和探索,试验证明,在轻型整车欧洲模式循环工况(NEDC)下,采用低温燃烧的标定策略,可以抑制柴油机排气中的NOx和颗粒(PM)含量,满足N1类整车国Ⅳ排放要求。
Calibration strategy and parameters for injection control were studied for light duty diesel engine during emission development of N1 class vehicle. It was showed by results that calibration strategy of low temperature combustion can be used to inhibit content of NOxand soot during New European Driving Cycle( NEDC) to meet the requirements of emission regulation.
