Abstract
An apparatus for supplementary fuel metering in the event of acceleration in an internal combustion engine, the apparatus developing signals by processing means indicative of a level of the increased quantity controllable in response to or in accordance with an operational status, operating characteristics and/or time for controlling an injection valve particularly in internal combustion engines which are driven in the lean range, the apparatus makes the increased quantity of fuel available for use to be dependent in the event of acceleration on the degree of leaning during the period before the acceleration process and dependent on the dimension of the desired acceleration itself. The apparatus for supplementary fuel metering includes a control apparatus for increased fuel quantities which is driven, for instance, in accordance with the output signals of an oxygen sensor and of a differentiating stage for the throttle valve angle.
