Abstract
An engine control system includes an injection determination module, a correction factor determination module, and a regeneration control module. The injection determination module determines a desired amount of hydrocarbons (HC) to inject into exhaust gas produced by an engine based a flow rate of the exhaust gas. The correction factor determination module determines a correction factor for the desired amount of HC based on engine speed and engine load. The regeneration control module controls injection of an adjusted amount of HC into the exhaust gas during regeneration of a particulate matter filter, wherein the adjusted amount of HC is based on the desired amount of HC and the correction factor.
