A fuel injection system for internal combustion engines is proposed which serves to inject a quantity of fuel adapted to the aspirated air quantity. In the intake tube of the engine, an intake tube section downstream of a throttle valve communicates with an intake tube pressure sensor via a connecting line. The output signal of this intake tube pressure sensor affects the opening duration of the injection valves. In order to reduce the influence of pulsations on the measurement product of the intake tube pressure sensor, a throttle valve is provided which in the presence of the operational engine states of upper partial load and full load reduces the cross section of the connecting line.
