Exhaust Flaps for Passenger Cars
Exhaust flaps for passenger cars are integrated in the exhaust tract. The housing is either a precision casting or of welded sheetmetal construction. This is ordinarily combined with a DC motor actuator with a contact-free sensor. All actuators for our exhaust gas flaps are internally developed.
For gasoline engines, there is a variant of the diesel exhaust gas flap constructed as an acoustic flap. In this case, particular attention is paid to internal leakage in order to achieve optimum noise minimization performance. A range of different actuators from the Pierburg modular system can be used to control the acoustic flap.
