The electrical actuator can reach any desired wastegate position in a flash, regardless of the negative or positive system pressure. Its high clamping force ensures minimal leakage and consequently rapid boost pressure build-up. The result is very spontaneous responsiveness. Another advantage of the electrical actuator is the ability to open the wastegate completely. This allows the catalytic converter to light off quickly, thereby reducing exhaust gas emissions and fuel consumption, which is crucial to customers.
MAHLE has successfully produced wastegate actuators in series since 2009, and presented an advanced variant in 2013 that has also been launched in series.
