Abstract: Gas flow and sound control valve for an exhaust system of an internal combustion engine comprising a housing including an inlet, a first outlet, and a second outlet, and a valve member arranged within the housing for forming a first conduit connecting the inlet to the first outlet and/or a second conduit from the inlet to the second outlet, wherein the valve member can be moved relative to the housing between a first predetermined position in which the valve member closes the second conduit and a second predetermined position in which the valve member closes the first conduit, whereby the valve member is rotatable around a valve axis aligned parallel, in particular coaxial, to a centerline of the inlet.

Abstract: An exhaust system for an internal combustion automotive engine, comprising: a left exhaust tract connected or to be connected to a left group of cylinder of the internal combustion automotive engine and a right exhaust tract connected or to be connected to a right group of cylinder of the internal combustion automotive engine, the left and right exhaust tracts, each comprising a branching structure defining a tract inlet, at least one exhaust outlet directly or indirectly opening into atmosphere, and an interconnecting outlet interconnecting said left and right exhaust tracts, wherein said interconnecting outlets are interconnected with each other by a common exhaust gas cleaning and/or silencing device downstream said interconnecting outlets such that exhaust gas flows coming from said interconnecting outlets are unified within said common exhaust gas cleaning and/or silencing device.

Abstract: An exhaust system for an internal combustion automotive engine, such as a V engine or boxer engine, includes a left exhaust tract connectable to a left group of cylinders and a right exhaust tract connectable to a right group of cylinders. Each exhaust tract includes a tract structure defining a tract inlet for receiving exhaust gas ejected from the group of cylinders to which the exhaust tract is connectable, at least one exhaust outlet opening into the atmosphere, and a connection pipe extending between the tract inlet and the exhaust outlet. The connection pipe includes an inlet aperture for receiving exhaust gas from the tract inlet and an outlet aperture for transferring exhaust gas towards the exhaust opening. The left and the right connection pipes are joined to realize a pipe junction such that the connection pipes form a common connection aperture for transferring exhaust gas and the exhaust system includes at least one valve member for opening or closing the common connection aperture.
