Preparation and control of fuel supply

  • throttle to the motor/controller idling;
  • compact air mass meter (HFM, type B);
  • valve injectors with oblique injection;
  • «running losses ventil» function  (US);
  • function of diagnostic of leakage of fuel from the fuel tank (US).

Power in all upgraded engines remained unchanged.

Maximum torque has been achieved at lower engine speeds than at the previous models.

In general, increased torque at low rpm.

The parameters set at the factory can be changed at a service station, if necessary in the range from about 650 / min to 800 rev/min.
