摘要： A method of controlling fuel composition learning includes steps of monitoring changes in airflow within an engine to determine steady state conditions. The method further includes steps of initiating a fuel composition learning process during steady state conditions. A current fuel component concentration factor is updated using a temporary fuel component concentration factor. The temporary fuel component concentration factor is calculated as the average of an air/fuel correction factor. Once the current fuel component concentration factor is updated, the temporary fuel component concentration factor is reset. The air/fuel correction factor is reset to reflect any difference that existed between the temporary fuel component concentration factor and the air/fuel correction factor at the update time.

摘要翻译：控制燃料组成学习的方法包括监测发动机内的气流的变化以确定稳态条件的步骤。该方法还包括在稳态条件下启动燃料组合学习过程的步骤。使用临时燃料成分浓度因子来更新当前的燃料成分浓度因子。临时燃料成分浓度因子被计算为空气/燃料校正系数的平均值。一旦当前的燃料成分浓度因子被更新，临时燃料成分浓度因子被重置。空气/燃料校正因子被重置以反映在更新时间之间临时燃料成分浓度因子和空气/燃料校正因子之间存在的任何差异。

摘要： A cylinder intake air amount calculating apparatus for an internal combustion engine for calculating a cylinder intake air amount which is an amount of fresh air sucked into a cylinder of the engine, is provided. An intake air flow rate, which is a flow rate of fresh air passing through an intake air passage of the engine, is obtained, and an intake pressure and an intake air temperature of the engine are detected. A theoretical cylinder intake air amount is calculated based on the intake pressure, the intake air temperature, and a volume of the cylinder. A volumetric efficiency of the engine is calculated by dividing a preceding calculated value of the cylinder intake air amount by the theoretical cylinder intake air amount. The cylinder intake air amount is calculated using the volumetric efficiency, the intake air flow rate, and the preceding calculated value of the cylinder intake air amount.
