ABSTRACT:
Method, system, and controller for controlling exhaust gas temperatures by adjusting exhaust valve timing and/or fueling for one or more cylinders wherein normal operating cylinders receive additional fuel to compensate for the adjusted cylinders, thereby increasing exhaust gas temperatures. The method, system, and controller may be applicable in systems having an engine which emits exhaust gases having particulates which are captured by the particulate filter.
