摘要： An engine control system includes an injection determination module and an injection regulation module. The injection determination module determines a desired rate of hydrocarbon (HC) injection into exhaust gas produced by an engine for regeneration of a particulate matter (PM) filter. The injection regulation module increases a rate of HC injection from a first rate to the desired rate during a predetermined period before regeneration of the PM filter, wherein the predetermined period is based on a difference between a predetermined temperature and a temperature at an outlet of an oxidation catalyst (OC).

摘要： An apparatus and a method for enhancing diesel engine performance is provided. At low engine load and cold ambient temperatures, an intake air heater increases the engine load via an engine alternator, which in turn, enables the engine to burn more fuel by the process of combustion. The combusted fuel elevates exhaust gas temperatures, which thereby accommodates cold start, controls white smoke, and aids DPF regeneration.
