摘要： An aftertreatment system comprises a housing defining an internal volume. The housing includes an inlet, an outlet and a first sidewall. A sleeve is positioned within the internal volume and protrudes through the first sidewall. An inner shell is positioned within an inner region defined by the sleeve and defines a recess therein. The inner shell spaced apart from the sleeve so as to define a channel therebetween. A base is positioned within the recess and includes an injection port which is in communication with the internal volume. An injector is disposed on the base and is disposed completely within the recess. The injector is in fluidic communication with the internal volume via the injection port.

摘要： In an engine exhaust gas purifier having a urea-SCR-catalyst and an injector, the urea-SCR-catalyst is regenerated periodically to remove stack up sulfur caused by the diesel fuel, by stopping supply of urea water, and raising exhaust gas temperature to heat the catalyst. The injector locates in the downstream of cooling wind of a variable speed cooling fan which creates variable cooling wind based on the temperature of the cooling component like radiator, oil cooler, after cooler of the engine. At the regeneration of the urea-SCR-catalyst, controller changes preset fan-speed to higher speed to increase cooling wind to inhibit overheating.
