Methods and systems are provided for regenerating an aftertreatment device of a vehicle. In one example, a method may include adjusting conditions of the regeneration in response to a stickiness of the exhaust valve. Adjusting conditions may include adjusting an air/fuel ratio and/or a post-injection amount.

Methods and systems for regeneration of an exhaust aftertreatment device

An exhaust system includes first and second exhaust pipes each of which has an upstream end communicating with an engine and a downstream end. The exhaust pipes are of different lengths. A length equalizer includes an outer pipe and an inner pipe disposed within the outer pipe. Once end of the inner pipe communicates with a space between the inner and outer pipes. The longer of the two exhaust pipes communicates with the space between the inner and outer pipes of the length equalizer. The shorter of the two exhaust pipes communicates directly with the inner pipe of the length equalizer. The distance between the downstream end of the longer exhaust pipe and the inner end of the inner pipe of the length equalizer is substantially equal to the difference in length between the longer and shorter exhaust pipes.
