exhaust emission control is exercised to restrict the exhaust amounts of hc , co , nox , and the like . however , since the intake air amount for startup unduly increases due to an engine speed overshoot for startup , the exhaust amounts of hc , co , and nox increase excessively . therefore , there is a need for optimizing the intake air amount for startup . the present invention proposes an engine startup control method that assures excellent startability and low exhaust emissions . disclosed is an engine control device for starting an engine . the engine control device includes a section for setting a target engine operating state of each combustion ; a section for detecting an actual engine operating state of each combustion ; and a section for computing a control parameter for each subsequent combustion in accordance with the target engine operating state of each combustion and the actual engine operating state of each combustion .
