Abstract: In a fuel injection system with an acceleration enrichment and a deceleration leaning, in which the transition compensation is determined by means of the throttle valve change speed in connection with the throttle valve change path. By means of the measurement of the throttle valve position the cause for the change of the air quantity is determined so that the information concerning a change of the operating state is present more quickly and a fuel leaning or fuel enrichment can accordingly also be effected more quickly. An intermediate injection threshold, which activates an intermediate injection calculation when exceeded, is built in, in addition, for the acceleration enrichment.

Abstract: In a method and apparatus for controlling tank venting in internal combustion engines, a regenerative flow of fuel is released from the activated charcoal container to the negative-pressure side of the intake tube of the engine and an adaptation in the computer area for the fuel metering quantity simultaneously is prohibited, or vice versa, an adaptation is authorized and a regenerative fuel flow is prohibited, by cyclical triggering, as a function of whether the throttle flap angle drops below, or exceeds, a predetermined threshold value. Parallel to this, a continuous activated charcoal filter regeneration is provided that comes into play at relatively large air throughputs, by means of a branch line leading into the air filter area upstream of the throttle flap; furthermore, if the throttle flap angle threshold value is exceeded, both the regenerative fuel flow via the tank venting valve and the adaptation in the computer area are authorized.

Abstract: The invention relates to an electronically controlled fuel injection system for an internal combustion engine wherein all dependency on the supply voltage for the electro-hydraulic components is compensated for and/or the pressure-regulator characteristic dependent upon the pumped quantity is compensated for. With respect to the dependency of the electric fuel pump on the supply voltage, this is accomplished by means of a correction factor for the basic injection signal. Below a specific voltage value which corresponds to the voltage required for maintaining the system pressure, this correction factor becomes progressively larger. The pressure regulator characteristic dependent upon the quantity of fuel pumped is taken into account in the correction in a corresponding manner.
