20110000186 | EXHAUST SYSTEM FOR AN INTERNAL COMBUSTION ENGINE - An exhaust system for an internal combustion engine, having a first exhaust tract assigned to a first group of cylinders of the internal combustion engine, and having a second exhaust tract assigned to a second group of cylinders of the internal combustion engine, each exhaust tract comprising an exhaust gas purification device, a first silencer arranged on the outlet side of the respective exhaust gas purification device, and a second silencer arranged on the outlet side of the respective first silencer. Each exhaust tract includes a bypass line, it being possible for exhaust gas to be diverted via each bypass line, starting from the respective first silencer, bypassing the second silencers, and the bypass lines and hence the first silencers of both exhaust tracts being connected to one another by a mixing line. | 01-06-2011 |
20130008402 | SOUND TRANSMISSION SYSTEM - A sound transmission system of a motor vehicle, having an intake sound transmission device which can be coupled via a first tubular connecting element to an air intake manifold which leads to an internal combustion engine and via a second tubular connecting element to a vehicle interior, the first tubular connecting element being assigned a first switchable shut-off device, having a resonator device which interacts with the intake sound transmission device and can be coupled via a third tubular connecting element to the air intake manifold which leads to an internal combustion engine, the third tubular connecting element being assigned a second switchable shut-off device. | 01-10-2013 |
20130008737 | CONTROL DEVICE OF A MOTOR VEHICLE - A control device of a motor vehicle having a noise transmission system and an exhaust system, wherein the noise transmission system has, for manipulating an interior noise of the motor vehicle, at least one intake noise transmission device which can be coupled via a first tubular connecting element to an air intake pipe leading to an internal combustion engine, the first tubular connecting element being assigned a switchable shut-off device, and which can be coupled via a second tubular connecting element to a vehicle interior, wherein the exhaust system has at least one switchable shut-off device for manipulating an exterior noise of the motor vehicle, and wherein the control device manipulates the operation of the noise transmission system and of the exhaust system jointly as a function of an actuation of a common operating element by the driver. | 01-10-2013 |
20130008738 | SOUND TRANSMISSION SYSTEM - A sound transmission system of a motor vehicle, having an intake sound transmission device which can be coupled via a first tubular connecting element to an air intake manifold which leads to an internal combustion engine and via a second tubular connecting element to a vehicle interior, having a resonator device which interacts with the intake sound transmission device and can be coupled via a third tubular connecting element to the air intake manifold which leads to an internal combustion engine. | 01-10-2013 |
