    • An intake throttle valve is located in an intake passage upstream of first and second intake ports, such that intake air flows into mainly the first intake port to generate a swirl flow when an opening degree of the intake throttle valve is not larger than a predetermined value, and flows into both the first and second intake ports when the opening degree thereof is larger than the predetermined value. Furthermore, first and second fuel injection valves for respectively injecting fuel to the first and second intake ports are controlled to inject fuel from the first fuel injection valve when the opening degree of the intake throttle valve is not larger than about the predetermined value, and to inject fuel from both the first fuel injection valve and the second fuel injection valve when the opening degree of the intake throttle valve is larger than about the predetermined value.

    • An intake pressure sensor is provided in an intake manifold of a first cylinder. During steady operation, intake quantities of respective cylinders are sensed with an airflow meter provided in an intake pipe of an engine, and the intake quantity of the first cylinder is compared with the intake quantities of the other cylinders to obtain intake pressure variation correction coefficients of the other cylinders. Also, average intake pressure of the first cylinder is corrected with the intake pressure variation correction coefficients to calculate average intake pressures of the other cylinders. During transient operation, estimation intake pressure is anticipated from a target opening degree of an intake throttle valve with the use of a physics model. Intake quantities of the respective cylinders are calculated with the use of the estimation intake pressure and the intake pressure variation correction coefficients.
    • 进气压力传感器设置在第一气缸的进气歧管中。 在稳定操作期间,用设在发动机的进气管中的气流计检测各气缸的进气量,并将第一气缸的进气量与其他气缸的进气量进行比较,以获得进气压力变化校正系数 其他气瓶。 此外,利用进气压力变化校正系数校正第一气缸的平均进气压力,以计算其他气缸的平均进气压力。 在瞬时动作中,使用物理模型,从进气节流阀的目标开度预测估计进气压。 使用估计进气压力和进气压力变化校正系数来计算各气缸的进气量。
