    摘要： An engine control apparatus for controlling the amount of the air flowing into each cylinder in accordance with the amount (TICy1) 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 (TgTp) 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 (TICy1) 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 (TI S) and unbalanced liquid film amount (TI US). Based on the unbalanced liquid film amount (TI US), the injection fuel amount is corrected so that the amount (TICy1) of the fuel flowing into the cylinder is controlled with high accuracy.
