| Abstract: | The effects of the fuel injection pulse width,the ignition advance angle and the parameters of engine start PID controller on the engine starting behavior was researched on a turbocharged gasoline direct injection engine with the self-developed software and hardware of the engine control system.The test results showed that the fluctuation of the engine starting speed is small when the fuel injection pulse width is 45 ℃A.The engine starting torque is the maximum for the ignition advance angle 12 ℃A.The optimal parameters of the PID control system are as follows: the speed responses quickly at KP=1;the error-free speed tracking and the small overshoot are reached at KI=0.2;and the control time is short and the speed becomes steady quickly at KD=1. |
