A heater for a vehicle exhaust system includes a housing defining a fluid chamber, and the housing has a fluid inlet configured to receive fluid from a fluid supply and a fluid outlet. A helical body is positioned within the fluid chamber and a heater is integrated into the helical body to heat fluid supplied from the fluid supply such that heated fluid can be injected into a vehicle exhaust component via the fluid outlet. At least one sensor is integrated into the helical body to measure a fluid characteristic.

A mixer assembly for a vehicle exhaust system includes an inner wall surface and a flow diverter with a flow directing surface that is spaced apart from the inner wall surface to provide an exhaust gas inlet area. The flow directing surface terminates at a distal end that is spaced apart from the inner wall surface to provide an orifice between the distal end and the inner wall surface through which exhaust gas flow accelerates and is directed to flow along the inner wall surface. A vehicle exhaust component assembly that includes the mixer and a method for mixing injected fluid spray into the mixer are also disclosed.

A vehicle exhaust system includes an injector assembly having an injector mount configured to mount an injector to an exhaust component. The injector mount includes a spray opening surrounding a spray axis. An injector housing extends from an inlet end that receives exhaust gases to an outlet end. The inlet end defines a planar area that is transverse to the spray axis. A spray protector extends axially from the injector mount to break the planar area. A vehicle exhaust component assembly comprising a mixer with the injector assembly and a method for injecting a fluid into an exhaust component using the injector assembly are also disclosed.

A vehicle exhaust system includes an injector assembly having a cone positioned adjacent to an injector mount and which extends from an upstream inlet end to a downstream outlet end. Engine exhaust gas and injected spray enter the inlet end of the cone to mix with each other prior to exiting the cone via the outlet end. The cone has a narrowing body portion located downstream of the inlet end to accelerate flow during mixing. A vehicle exhaust component assembly comprising a mixer with the injector assembly and a method for injecting a fluid into an exhaust component using the injector assembly are also disclosed.

Venturi style injector cone

A vehicle exhaust system includes an exhaust component having an inner wall to define an internal cavity that provides an engine exhaust gas flow path from an inlet to an outlet. An injector is configured to spray a fluid into the internal cavity to mix with engine exhaust gas. An inlet baffle is mounted to the exhaust component adjacent the inlet and includes at least one scoop having a scoop length that is greater than a scoop width. The scoop includes a scoop opening that directs engine exhaust gas toward the inner wall of the internal cavity at a location that is upstream of spray injected by the injector.

Mixer for a vehicle exhaust system

An automotive vehicle includes an exhaust aftertreatment system. The exhaust aftertreatment system includes a mixer, a doser that injects a reducing agent into the mixer, and a selective catalytic reduction unit. The exhaust aftertreatment system mixes exhaust gases and the reducing agent for treatment prior to the exhaust gases being discharged into the atmosphere. Some components of the exhaust aftertreatment system are positioned proximate to an associated combustion engine to minimize thermal energy loss from the exhaust gases prior to interaction with the exhaust aftertreatment system.

An automotive exhaust aftertreatment system for a combustion engine in an automobile includes an ammonia gas distribution system for delivering gaseous ammonia to an exhaust stream. The ammonia gas distribution system is configured to mix the ammonia and the exhaust stream together before the exhaust gas and ammonia are exposed to a catalyst in the SCR.

By using a spun extrusion method to form a side entry exhaust inlet, a muffler can be completely stuffed and end caps can be spun onto opposing ends of the muffler on a high speed production line without interruptions. The side entry exhaust inlet is formed within a muffler shell at a position between the opposing ends. A spinning tool engages an internal peripheral area of the side entry exhaust inlet to form a spun extruded surface that extends outwardly from the muffler shell.
