Abstract
The control parameters of electronic governor that influence the transient characteristics of the engine are analyzed. An electric control unit was developed and the control parameters were calibrated on the test bench. The initial value of integral term and the maximum output of rack position proportion, integration and derivation (PID) controller affect the step and triangle response drastically. Through correcting the proportional term and integral term of speed PID controller, the dynamic speed drop and speed overshoot are improved. A property control strategy for cold starting an engine is set, and the calibration process indicates that the fuel injected into the cylinder per cycle and the desired speed ascend rate drastically affect the start transient process.
