Abstract (en)
[origin: WO9108390A1] The system proposed includes means for determining a basic injection-quantity signal and a transitional compensation signal for regulating the measured amount of fuel when accelerating and decelerating. Depending on engine load and rpm, a cylinder-wall fuel-film signal and a control-factor signal (Tk) are generated, and the transitional compensation signal takes into account both the cylinder-wall fuel-film signal and the control-factor signal. The control-factor signal can either be extracted from a characteristic plot or be two discrete values. The system proposed gives optimum transitional behaviour as regards engine exhaust characteristics.
