Zusammenfassung Noise reduction of passenger car engines contributes to an improvement of the driving comfort at low and medium speeds. It also helps to meet the acoustic regulations of the legislative authorities that force lower sound pressure levels of the pass-by-noise of cars in the next years. An option to reduce the noise radiated from the engine is the application of a full or a partial engine encapsulation.
