Abstract
An engine control apparatus includes an engine information detector for detecting engine information including an engine speed, a fuel amount, an air amount, a boost pressure, injection timing, an intake air temperature, an atmospheric pressure, and an atmospheric temperature, a combustion pressure sensor for detecting a combustion pressure of an engine, and a controller performing an IMEP control for adjusting a main injection amount and a combustion noise control for adjusting a pilot injection amount by using the engine information detected by the engine information detector and the combustion pressure detected by the combustion pressure sensor, and calculating a final main injection correction amount and a final pilot injection correction amount by using an IMEP pilot correction amount and an IMEP correction amount outputted from the IMEP control and a combustion noise correction amount outputted from the combustion noise control.
