An engine control system includes an injection determination module and an injection distribution module. The injection determination module determines a desired amount of hydrocarbons (HC) to inject into exhaust gas produced by an engine for regeneration of a particulate matter (PM) filter. The injection distribution module controls a ratio of auxiliary injection to post-combustion injection based on engine load, engine speed, and the desired amount of HC injection, wherein auxiliary injection includes injecting HC into the exhaust gas, and wherein post-combustion injection includes injecting HC into cylinders of the engine during a period after combustion. |
