Abstract (en)

[origin: EP0922845A2] In fuel injection quantity control of a diesel engine, to suppress deterioration of drivability caused by smoothing processing during increase in the fuel injection for acceleration, a road load injection quantity lower limit is set as a basic fuel injection quantity QBASE at start of the smoothing processing for acceleration. This road load injection quantity lower limit is the one corresponding to a minimum friction allowed in the diesel engine. Thus, if a diesel engine to be controlled has a friction smaller than the average friction, the fuel injection quantity can be prevented from being increased sharply far beyond an actual road load injection quantity, thus suppressing the acceleration shock to prevent deterioration of drivability. Further, the stepwise increase in the fuel injection quantity for acceleration at the start of smoothing processing is maintained, thus satisfying the acceleration performance. <IMAGE>
