Abstract
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.
