Abstract (en)

[origin: WO9632579A1] Calculating the mass of air actually flowing into the cylinder with the aid of an inlet pipe filling model which, from the factor angle of throttle valve aperture, environmental pressure and parameters representing the valve control, provides a load value on the basis of which the injection time is determined. In addition, this load value is used in predictions for estimating the load value at a time at least one sampling step later than the actual calculation of the injection time.
