| Abstract: | For 4JB1 diesel high-pressure common rail diesel engine,the characteristics of three conditions,which included the steady idle,transition from start to idle and transition from high speed to idle,were researched.Under different transient conditions,the idle fuel control compensation algorithm and DT1 algorithm were used.Under steady idle conditions,the PI controller was used and the parameters were amended in real time.The control strategy was verified to be reasonable through the experiment.The idle speed ... |
