Abstract

The article contains a functional analysis of the diesel engine ECU controller in terms of estimating the fuel dose correction signal. The reasons for introducing fuel dose correction for injectors in the area of limit values were analyzed, indicating the need for the diesel engine diagnostic process according to OBDII procedures in terms of changes in this parameter during engine operation. It is possible to use the engine ECU controller to implement extended functional diagnostic procedures in the scope of controlling the increase in the fuel dose correction value in a continuous system after implementing the supplemented software. Observing the trend of fuel dose correction variability will determine in advance the risk of an error code and MIL indicator light for the diesel engine power supply system.
