燃料噴射制御方式。 In a turbocharged diesel engine, the fuel injection control device includes sensors such as an engine rotation sensor, rack position sensor, and accelerator sensor, and a controller that instructs the actuator of the electronic fuel injection control governor based on information from the sensors. During operation, when an accelerator opening signal is input to the controller, the rack position Ra corresponding to the input accelerator opening is determined, and the rack position R is
a and smoke limit easy position Rs at each boost pressure 1
In contrast, when the rack position Ra corresponding to the accelerator opening is smaller than Rs 1 , the rack remains R.
The system is characterized in that it instructs the engine to move to the position a, and when Ra is greater than Rs 1 , instructs the easy position of Rs 1 , and further estimates the boost pressure t seconds after the supercharger response time constant. Electronic fuel injection control system for diesel engines.
