Compression control
This function gives a possibility to control the compression on the basis of speed deviations at start speed.
Note:
The function only gives a reference to incorrect compression ratio. At large deviations, use a compression tester!
Conditions du test :
Contact mis, moteur arrêté.
Transmission au point mort.
Chargeur de batterie raccordé au véhicule.
Procédure :
Démarrer la fonction.
The starter motor will be activated for about 10 seconds. The engine will not start!
Do not turn of the ignition while the control is in progress!
The function will present data lists with speed for the different cylinders separately.
If one or more cylinders deviates in speed, check these with a compression tester!
Reference values when measuring with a compression tester:
Compression values bar over pressure.
New 25,0-31 bar.
Wear limit 19,0 bar.
Maximum difference between the cylinders 5,0 bar.
