| 摘 要： | 建立了带EGR回路的增压柴油机瞬态仿真平台并验证了准确性.为了缩短EGR阶跃工况的响应时间,进行了EGR阀开度阶跃时间、开阀特性、目标EGR率等影响因素的不同控制策略的对比.结果表明,缩短EGR阀开度阶跃时间,采用“上抛型”开阀控制策略,可改善EGR流量等参数的瞬态响应特性,但会造成转矩波动增加.为减少转矩波动,提出了... |

| Abstract: | A simulation platform of turbocharged diesel engine with EGR loop under transient operations was com-pleted and verified.In order to shorten the transient response time of EGR step change operation,different control strategies for EGR step change time,EGR open valve characteristic and target EGR rate were compared.Results show that shortening EGR step change time and adopting the upcast open valve characteristic control strategies can,on the one hand,improve the transient response of EGR flow mass rate,but,... |
