    • 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.
    • 提供一种用于计算吸入到发动机的气缸中的新鲜空气量的汽缸进气量的内燃机的汽缸进气量计算装置。 获得作为通过发动机的进气通道的新鲜空气的流量的进气流量,并且检测发动机的进气压力和进气温度。 基于进气压力,进气温度和气缸体积计算理论气缸进气量。 通过将汽缸进气量的先前计算值除以理论气缸进气量来计算发动机的体积效率。 使用体积效率,进气流量和前一个计算出的气缸进气量的值来计算气缸进气量。
