Abstract
A method of selective hydrocarbon injection in in-cylinder late post injection in an exhaust manifold of a diesel engine comprises providing the exhaust manifold of the diesel engine comprising a plurality of cylinders, an exhaust gas recirculation valve disposed adjacent the exhaust manifold, a diesel particulate filter disposed adjacent the exhaust manifold, an exhaust gas recirculation cooler disposed adjacent the exhaust manifold offset from the exhaust gas recirculation valve, and an engine control unit operatively connected with the diesel engine for controlling at least the plurality of cylinders. At least a first cylinder is disabled via the engine control unit to reduce post injection of hydrocarbons during regeneration of the diesel particulate filter. The diesel particulate filter is regenerated. In-cylinder late post injection of hydrocarbons is conducted during regeneration of the diesel particulate filter via cylinders other than the first cylinder.
