United States Patent Application

View the Complete Application at the US Patent & Trademark Office
A GDCI engine recirculates exhaust gases to a combustion chamber using desired early injection parameters for a steady state engine operation from a controller. An engine control system detects a load increase relative to the steady state engine operation, and insufficient recirculated exhaust gases to the combustion chamber are delivered in response to the detected load increase as a result of transport delays. A last fuel injection into the combustion chamber during an engine cycle with multiple fuel injections is delayed as compared to the steady state engine operation. Combustion phasing within the combustion chamber is retarded in response to the delayed injection.
