摘要： A control arrangement in internal combustion engines for controlling a group of electromagnetically actuated injection valves simultaneously. A monostable multivibrator provides pulses synchronously with the rotational speed of the engine for the purpose of determining the opening duration of the injection valves as a function of at least one operating parameter, particularly the intake manifold pressure. A first electronic circuit operable only when the throttle valve is closed, inhibits the pulses when the engine is above an upper limit, and switches the pulses back on when the engine speed is below a lower limit which is above the idling speed. A second electronic circuit which is operable at all positions of the throttle, serves to switch off the pulses when the engine speed is above a maximum value, and then switches the pulses back on when the speed drops below this maximum value.
