  • Patent number: 9273616
    Abstract: An intake control system for an internal combustion engine is capable of ensuring a differential pressure across an EGR valve, and controlling an EGR amount with high accuracy. A target fresh air amount is set based on a demanded torque calculated according to operating conditions of the engine. A differential pressure across an EGR valve is set as a target differential pressure. When it is determined that the across-valve differential pressure is not in a state in which the target differential pressure can be ensured, an opening degree of the EGR valve is controlled to limit an EGR amount. An opening degree of a throttle valve is controlled based on the target fresh air amount, so as to ensure the target differential pressure.

  • Publication number: 20140060485
    Abstract: An intake control system for an internal combustion engine, which, even when there are a plurality of intake air amounts for attaining one target torque, is capable of positively selecting a minimum intake air amount therefrom without causing hunting, and setting the minimum intake air amount as a target intake air amount, thereby making it possible to improve fuel economy. The intake control system calculates a maximum intake air amount, sets a plurality of provisional intake air amounts within a range of 0 to the maximum intake air amount, calculates torques estimated to be output from the engine with respect to the provisional intake air amounts, respectively, selects a minimum provisional intake air amount that makes the estimated torque equal to or close to the target torque from the relationship between the provisional intake air amounts and the estimated torques, and sets the same as the target intake air amount.

  • Publication number: 20140067212
    Abstract: A control system for an internal combustion engine, which is capable of quickly and properly ensuring excellent fuel economy of the engine even when atmospheric pressure has changed. The control system includes an ECU. The ECU performs weighted average calculation on lowland map values and highland map values, based on atmospheric pressure, to thereby calculate map values of a demanded torque that minimize a fuel consumption ratio of the engine in the atmospheric pressure, and calculates engine demanded output. The ECU calculates demanded torque and demanded engine speed using the map values and the engine demanded output, respectively. The ECU controls the engine using the demanded torque.
