Internal combustion engine e.g. diesel engine, operating method for motor vehicle, involves determining correction value for control timing of valve and changing control timing by correction value, during prospective control of valve

摘要

The method involves controlling an injection valve for a predetermined testing period and determining a fuel quantity actually injected from the valve from the pressure characteristics in a combustion chamber. A fuel quantity expected for the testing period is determined from the characteristics of the valve. The difference between the expected quantity and the actual quantity is estimated. A correction value for a control timing of the valve is determined, such that the difference value is zero. The control timing is changed by the correction value, during prospective control of the valve.
