ABSTRACT:
An apparatus and method for reducing white smoke during start up of a compression ignition engine is disclosed. The apparatus includes an engine cylinder, a fuel injector, an engine speed sensor, and a microprocessor. The microprocessor preferably includes an engine speed controller that governs the engine speed to a desired value. The microprocessor issues a first fueling level corresponding to a difference between an actual engine speed and the desired engine speed signal. The microprocessor quits fueling the engine cylinder then determines a second fueling level. A determination about whether the cylinder is firing is then based on a comparison between the first and the second fueling level.
