A turbocharger having a turbine housing including an outer surface and an inner surface defining an exhaust passage, an exhaust inlet port in fluid communication with the exhaust passage, and a tucked exhaust inlet flange surrounding the exhaust inlet port, the exhaust inlet flange including a plurality of bolt holes arranged in a trapezoid shaped bolt pattern.

A tunable insert assembly for a tunable exhaust system is disclosed for use with an air intake engine of a vehicle. The tunable exhaust system may include an intake tube having first and second ends with a first flange, an exhaust tube having third and fourth ends with a second flange, and a clamp to securely affix the first flange of intake tube to the second flange of exhaust tube. The tunable insert assembly may comprise a register ring, insert, and orifice plate with an opening. The insert may be perpendicularly disposed through the opening of orifice plate, while the register ring may be disposed over and circumferentially surrounds an outermost surface of orifice plate. Lastly, the exhaust system may be configured to produce a desired range of tunable sound pressure levels and a desired tunable sound frequency range based on various predetermined diameters and lengths related to the insert(s).

A fuel injector for an exhaust heater includes a cover and an air blast nozzle. The cover has a nozzle seat, a fuel inlet, and an air inlet, the nozzle seat arranged along a flow axis. The air blast nozzle is seated in the nozzle seat and has a unibody. The air blast nozzle unibody is in fluid communication with the fuel inlet and the air inlet arranged along the flow axis to port fuel and air into a combustion volume, e.g., to heat a stream of exhaust gas flowing between an engine and a catalytic reactor by combustion with fuel introduced through the fuel inlet and air introduced through the air inlet.

An engine exhaust manifold including exhaust inlet parts at four locations corresponding to a plurality of exhaust ports, one exhaust outlet part, and an exhaust confluence part to collect exhaust gas from each of the exhaust inlet parts and send to the exhaust outlet part. An EGR passage part to send EGR gas toward an intake passage is formed.

A turbocharger having a turbine housing including an outer surface and an inner surface defining an exhaust passage, an exhaust inlet port in fluid communication with the exhaust passage, and a tucked exhaust inlet flange surrounding the exhaust inlet port, the exhaust inlet flange including a plurality of bolt holes arranged in a trapezoid shaped bolt pattern.

A connection unit for connecting two exhaust gas-carrying assembly units of an exhaust system of an internal combustion engine, includes a ring washer-shape connection element (26) with a connection side (42), which is to be positioned to face a counter-connection element (24) to be connected to the connection element (26) or/and in contact with the counter-connection element (24). A passage opening (28), bordered by an inner circumferential surface (36) of the connection element (26), receives a connection pipe (30), which is inserted into the passage opening (28) and extends in the direction of a pipe longitudinal axis (L). The connection pipe (30) is connected to the connection element (26) in the area of the inner circumferential surface (36) by welding, or/and the connection pipe (30) projects with a centering section (40) on the connection side (42) of the connection element (26).

An exhaust pipe structure of an internal combustion engine vehicle is provided, which includes a coupling part coupling a first exhaust pipe to a second exhaust pipe disposed serially. The coupling part includes an insertion pipe part formed in the second exhaust pipe, an outer circumferential pipe part formed in the first exhaust pipe and to which the insertion pipe part is inserted, an inner circumferential pipe inserted into the outer circumferential pipe part, an annular protrusion formed in the second exhaust pipe and protruding radially outward from the entire circumference of the insertion pipe part, and a clamp member coupling the outer circumferential pipe part to the annular protrusion. The clamp member has a band part wrapped radially outside around a part where a flare part of the outer circumferential pipe part overlaps with the annular protrusion, and a tightening part tightening the band part.

The present invention relates to an improved turbocharger assembly, particularly of the variable geometry type. The improved turbocharge assembly contains a turbine. The turbine includes an impeller housed in a casing, a flange that can be sealingly associated with a corresponding flange of an exhaust gas manifold of an engine, and a clapet valve that contains a shutter element and a housing seat. The housing seat is fashioned in a frame made in one piece with the casing.

A fastening device for fastening a decoupling device relative to a hole rim of a hole opening of a shielding part; to achieve the vibration-decoupling connection of a bushing to the shielding part, the decoupling device has at least one bridge element, which, at its radially outer edge, has fasteners for producing a fastening connection of the bridge element to the hole rim of the shielding part, wherein the fasteners comprise at least four tabs which, starting from the bridge element, protrude radially outward and a subset of at least two tabs of the bridge element is provided to rest against a first outside of the shielding part and a remainder of at least two tabs is provided to rest against an opposite second outside of the shielding part and the hole rim can be immobilized with a force fit relative to the decoupling device by means of the tabs of the subset and the tabs of the remainder.

An exhaust assembly for a vehicle. The exhaust assembly includes a header assembly including one or more head pipes, and a bridge with a first end and a second end that is opposite the first end. The first and second ends are secured to the header assembly. The exhaust assembly further includes a shield assembly including a shield shaped to cover a portion of the header assembly and a retainer secured to the shield and supported by the bridge by a planar clamp joint therebetween.
