In recent years, the ANC technology was adapted for intake and exhaust systems on several passenger vehicles with a variety of diesel and gasoline engines. In these predevelopment activities, the active components (actuators, electronic hardware and software) were rigorously improved and its durability professionally validated leading to an increased system performance even under very harsh conditions. Depending on the customer targets, this yielded several benefits when compared to conventional exhausts. For example, a passive conventional dual exhaust system of a highly efficient 4-cylinder gasoline engine could be replaced by an active single exhaust line without compromising on the acoustic targets but saving a considerably amount of design space and weight. In particular, the space advantage can be utilized to create innovative exhaust layouts. To support future downsizing of engines, for example, an ultra-compact exhaust layout is proposed.
