    • A control apparatus for an internal combustion engine having a throttle valve disposed in an intake passage of the engine is provided. A wide-open intake air amount, which is an intake air amount corresponding to a state where the throttle valve is fully opened, is calculated, and a theoretical intake air amount, which is an intake air amount corresponding to a state where no exhaust gas of the engine is recirculated to a combustion chamber of the engine, is calculated according to the wide-open intake air amount and the intake pressure. An air-fuel ratio correction amount and a learning value thereof are calculated according to the detected air-fuel ratio, and a reference intake air amount is calculated using the intake pressure, the engine rotational speed, the air-fuel ratio correction amount, and the learning value. A lower limit value of the detected intake air amount is set according to the reference intake air amount, and a limit process is peformed for limiting the detected intake air amount within a range of values which are equal to or greater than the lower limit value. An amount of the evaporative fuel/air mixture supplied to the intake passage is calculated, and the limit-processed intake air amount is corrected using the evaporative fuel/air mixture amount to calculate an intake gas amount. An exhaust gas recirculation ratio is calculated using the theoretical intake air amount and the intake gas amount.
    • 提供了一种用于内燃机的控制装置,该内燃机具有设置在发动机的进气通道中的节气门。 算出与节气门全开的状态相对应的吸入空气量即全开吸入空气量和作为与没有排气的状态相对应的吸入空气量的理论吸入空气量 的发动机再循环到发动机的燃烧室,根据全开进气量和进气压力来计算。 根据检测到的空燃比计算空燃比校正量和其学习值,并且使用进气压力,发动机转速,空燃比校正量以及空燃比校正量来计算基准进气量 学习价值。 根据基准进气量设定检测到的进气量的下限值,并且执行限制处理以将检测到的进气量限制在等于或大于下限值的值的范围内。 计算供应到进气通道的蒸发燃料/空气混合物的量,并且使用蒸发燃料/空气混合量校正极限处理进气量以计算进气量。 使用理论吸入空气量和吸入气体量来计算排气再循环率。
