    摘要： An engine control apparatus for controlling the amount of the air flowing into each cylinder in accordance with the amount of the fuel flowing into the cylinder at the time of starting the engine is disclosed. Further, at the engine starting time, the target amount of the air flowing into the cylinder is calculated and/or the amount of the air flowing into the cylinder is controlled, based on the amount of the fuel flowing into the cylinder. The amount of the fuel remaining in the neighborhood of the engine intake port or in the intake pipe is calculated by being separated into a balanced liquid film amount and unbalanced liquid film amount. Based on the unbalanced liquid film amount, the injection fuel amount is corrected so that the amount of the fuel flowing into the cylinder is controlled with high accuracy.

    摘要： Exhaust emission control is exercised to restrict the exhaust amounts [g] 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 (small gas amount). Disclosed is an engine control device for starting an engine (from its stop state). 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.
