The ME-SFI limiting maximum vehicle speed function - GF07.61-P-3019V
ENGINE 273.961 in MODEL 216, 221 up to Model Year 8
Shown on engine 272.963 in model 171
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.
