Abstract: A method of quantifying a particulate matter in an exhaust stream includes the steps of accumulating a particulate matter on a sensor. The sensor provides a signal that varies based upon an amount of the particulate on the sensor. The sensor includes a measurement cycle that includes a deadband zone, followed by an active zone, which is followed by a regeneration zone. The particulate matter is calculated after an end of the deadband zone is reached and prior to an end of the measurement cycle.

Abstract: A system includes an exhaust system fluidly configured to define an exhaust stream.

Abstract: 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.

When the valve opens, the fuel flows into the compression chamber, pushed by the resilient member which takes back its original shape.
