Active surge dampening
Active surge dampening |
This function suppresses the engine speed variations caused by oscillations in the engine, gearbox, drive shafts and engine mountings.
Calculations for the function are performed using the following parameters
- |
Engine RPM
|
- |
Engine speed/vehicle speed (i.e. gear position)
|
- |
Fuel quantity
|
- |
Clutch switch
|
- |
Idle active
|
The result of the calculation is a correction quantity in mg/combustion for each cylinder. The limit for the range of correction is 10 mg/combustion.
The value from this function is added to the value from cylinder balancing.
