Abstract
A diesel engine injection timing signal interceptor module comprised of a micro-controller-based control module and interface circuitry that intercepts engine speed and position signals from engine sensors and produces output signals which are shifted in time (advanced or retarded) relative to the sensor signals. By controlling the amount of time shift, the interceptor manipulates fuel injection timing. Use of the interceptor module provides the ability to reduce NOx emissions while achieving acceptable fuel consumption, without having to change the engine's sensors, electronic controller or fuel injectors.
