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.

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.
