ABSTRACT:
The supercharge pressure and the pressure differential which develops between the supercharge pressure and the exhaust gas pressure upstream of a turbocharger turbine are monitored. In the event that the supercharge pressure is below a target level which is determined to optimal for the instant set of operating conditions, a first injection reduction amount is calculated. To allow for the effect of very sudden accelerations wherein the pressure differential tends to become large and the charging efficiency of the engine tends to reduce, a second reduction amount is calculated based on the difference between the actual differential and a target value for the instant set of operating conditions. The second reduction amount is also subtracted from the injection volume which is calculated based on the engine speed and a signal which is indicative of the power demand on the engine (the accelerator pedal depression degree).
