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 speed

- 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 resulting from the function is added to the value from cylinder balancing.
