Abstract
A system and method are disclosed for controlling an internal combustion engine in which actual concentration of combusted gas in the intake is compared with desired concentration of combusted gas in the intake. When a difference is detected, at least one of start of injection timing and quantity of fuel injected is adjusted in accordance with the difference. The actual concentration of combusted gas in the intake is estimated based on engine sensors such as an oxygen sensor coupled to an engine intake. The adjustment of injection timing and/or quantity of fuel is performed, according to some embodiments, during a transition between a low temperature combustion mode and a standard diesel combustion mode.
