    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.

    摘要： An engine controller capable of optimizing both the air-fuel ratio and the ignition timing to provide HC-minimized performance under the relevant driving conditions (environmental conditions) in order to minimize the amount of HC emitted from an engine at the time of start-up (before catalyst activation) is provided. The engine controller includes: air-fuel ratio control means for controlling the air-fuel ratio to be within a predetermined range (for example, 14.5 to 16.5) when the engine is operated at a certain driving condition (for example, in a state in which the catalyst is not activated such as the time of starting a cooler, or idling time); and ignition timing correction means for correcting the ignition timing to the retard side when the engine is operated at the certain driving condition and the air-fuel ratio is within the predetermined range.
