Fuel injection circuit for motor vehicle internal combustion engine uses base functioning condition on which is superimposed calculated injection period

摘要

The fuel injection circuit for a motor vehicle internal combustion engine has an electronic control which calculated the amount of fuel imposed on a base functioning condition (100,110) and calculates the injection synchronization depending on the provisional injection period (180). It calculates a new injection period based on fuel pressure and the selected injection quantity when the pressure is correctly detected (250).
