In order to limit maximum vehicle speed on vehicles with a corresponding engine power output, the throttle valve is closed and the quantity of fuel injected is reduced accordingly once a speed of 250 km/h is reached. In addition, the ignition angle is adjusted to "Late".

These measures ensure simple maximum speed limitation by reduction of the torque.
