An assembly for connecting a line includes a connector for detachable connection of a line, a line that can be connected to the connector, and an intermediate element for connection to the connector and the line. The intermediate element is secured on the line in such a manner that it separates the line and the connector from one another.

A turbine housing defining a pair of volutes with respective outlets divided by a divider wall, includes a diffuser space in the gas flow path between the volutes and the turbine wheel. The diffuser space has an upstream portion having a smaller axial extent than a downstream portion of the diffuser space. The widening of the diffuser space tends to direct exhaust gas entering the diffusion space from at least one side of the divider wall towards the corresponding axial end of the diffuser space. Thus reduces the tendency of this gas to interrupt the flow into the diffuser space of exhaust gas from the other inlet volute.

A snowmobile includes a frame, at least one ski, handbars operatively coupled to the at least one ski, and an engine assembly comprising an engine and an exhaust manifold. The exhaust manifold includes at least a first inlet, a first outlet, and a second outlet. The first inlet is configured to connect to a first exhaust port. The first outlet is connected to provide exhaust received from the first inlet to a first exhaust path and the second outlet is connected to provide exhaust received from the first inlet to a second exhaust path.

In an exhaust gas flow control system for an internal combustion engine, with a first exhaust gas duct and a second exhaust gas duct, through both of which exhaust gas from the internal combustion engine can flow to a turbine of an exhaust gas turbocharger with an exhaust gas recirculation line branching off the first exhaust gas duct, a shut-off element is provided which is adjustable between a closed position in which exhaust gas is prevented from flowing into the exhaust gas recirculation line and directing it via a communication passage into the second exhaust gas duct, and at least a first open position in which exhaust gas is directed out of the first exhaust gas duct into the exhaust gas recirculation line while blocking the communication passage between the first and second exhaust gas ducts and a second open position wherein both the first and the second exhaust gas ducts as well as the communication passage between the two ducts is open but the recirculation line is closed.

An exhaust system is disclosed for a use with an engine. The exhaust system may have a plurality of manifold sections, each being connected to an adjacent one of the plurality of manifold sections and thereby forming an exhaust manifold. The exhaust system may also have a plurality of elbow-shaped coolant adapters, each being configured to connect a corresponding one of the plurality of manifold sections to a corresponding cylinder head of the engine and having a coolant jacket formed therein. The exhaust system may further have a heat shield formed around the exhaust manifold.

Methods and systems are provided for a boosted engine having a split exhaust system. In one example, a method comprises directing exhaust from a first cylinder group to one or more of a pre-compressor location, a post-compressor location, and an exhaust turbine, and directing exhaust from a second cylinder group to one or more of the pre-compressor location, and the exhaust turbine. Engine efficiency and knock control may be enhanced by directing exhaust gases to different locations based on engine operating conditions.
