Abstract
A system and/or method of controlling smoke or noise emanating from a diesel engine wherein a throttle is drivingly coupled to the diesel engine, and wherein an operator of the engine changes a throttle position. The system may comprise a high pressure fuel pump in fluid communication with a fuel reservoir, a fuel accumulator, in fluid communication with the high pressure fuel pump, one or more injectors that are in fluid communication with the fuel accumulator and each of the fuel injectors. A main controller transmits a signal in response to a change in the throttle position. A fuel injection controller, in electrical communication with the main controller, in response to one or more signals relative to a transient operation, transmits one or more signals relative to fuel injection parameters of a fuel injection made during the transient operation.
