Abstract
There is proposed a control apparatus (FIG. 1), which in order to prevent the emission of smoke upon acceleration of the engine, controls a damping stroke (h.sub.D) preceding the adjusting stroke (h.sub.L) which is controlled in accordance with charge pressure. The apparatus has a pressure chamber defined by a movable wall and connected via charge air line to the air inlet tube of the engine, and the movable wall actuates an adjusting member which varies the adjusting range or the full-load position of a supply quantity adjusting member of a fuel injection pump. A throttle device embodied as a sequence valve is inserted into a line connecting portion connecting the charge air line with the pressure chamber, and the stroke/time characteristic of the throttle device determines the damping stroke (h.sub.D). The apparatus may be mounted either on the rpm governor or on the injection pump of Diesel motor vehicle engines.
