Task

Limiting maximum engine speed

-----------------------------------------------------------------------------------------

Function

The engine control module detects the engine speed from the crankshaft position sensor signal. Engine speed is limited by shutting off the fuel injectors in the following conditions in order to protect the engine and the drive train:

-----------------------------------------------------------------------------------------

1. Protection of torque converter in selector lever position P/N

Engine speed is limited (e.g. to about 4000 rpm in the case of engine 104) in order to protect the torque converter from increased static internal pressure in selector lever positions P and N (no power flow).

2. Limiting maximum engine speed when driving

Engine speed is limited to 6600 rpm and, after a further
3.5 seconds, to about 6400 rpm (e.g. engine 104) in order to protect the engine from the consequences of impermissibly high revs.

-----------------------------------------------------------------------------------------

The driving mode is detected from the vehicle speed signal.

3. Safety fuel shutoff (only in combination with CC)

If the throttle valve is opened further than the input from the accelerator pedal and if the car is not operating the cruise control mode, the engine control module shuts off the fuel injectors at engine speeds > 1400 rpm and actuates them again at engine speeds < 1200 rpm (surging).
