摘要： Various systems and method are described for controlling an engine having an exhaust system which includes a particulate filter. One example method comprises, after shutting down the engine and spinning down the engine to rest, operating a vacuum pump to draw fresh air through the exhaust system to an intake system, and regenerating at least a portion of the particulate filter during the engine rest.

摘要： Methods and systems are provided for controlling exhaust emissions by adjusting a fuel injection into an engine cylinder from a plurality of fuel injectors based on the fuel type of the injected fuel and further based on the soot load of the engine. Soot generated from direct fuel injection is reduced by decreasing an amount of direct injection into a cylinder as the engine soot load increases.

摘要： Systems and methods for controlling regeneration of a particulate filter positioned downstream of an engine in a vehicle are provided herein. One exemplary method includes, during combusting engine conditions, directing exhaust from the engine to a three-way catalyst and then to a particulate filter positioned downstream of the three-way catalyst. The method also includes, during non-combusting engine conditions and while the vehicle is in motion, directing fresh ram-air to the particulate filter to regenerate the particulate filter.

摘要： Method and electronic control system using a unique driver demand (calibration) table stored in system memory to provide torque output values specific to a 4×4 mode of operation of the vehicle drive unit. For example, the torque output of the electronic control system for a 4×4 low mode of operation is controlled using a unique calibration table stored in system memory for 4×4 low mode of operation, while the torque output of the electronic control system for other modes of operation is controlled using one or more different, other calibration tables stored in system memory.

摘要： Systems and methods for controlling regeneration of a particulate filter downstream of an engine in a vehicle are provided herein. One exemplary method includes, during an engine shutdown, increasing a throttle opening and regenerating a particulate filter downstream of a three-way catalyst. The method also includes, during an engine start following an engine shutdown, setting one or more engine parameters based on whether the particulate filter was regenerated during a last engine shutdown before the engine start.
