  • Patent number: 9964027
    Abstract: The objective of the present invention is to provide a controller for a supercharger-equipped internal combustion engine and a control method that can reduce man-hours for data measurement and matching, which are required to perform while the internal combustion engine and the supercharger are combined. In a controller, a target turbine flow rate for realizing a target compressor driving force is calculated; a target wastegate flow rate is calculated based on an exhaust gas flow rate and the target turbine flow rate; a target turbine-upstream pressure is calculated based on a target before/after-turbine pressure ratio for realizing the target compressor driving force and a turbine-downstream pressure; a target gate effective opening area is calculated based on the target wastegate flow rate, the target before/after-turbine pressure ratio, and the target turbine-upstream pressure; then, a gate valve control value is calculated.

  • Patent number: 9957883
    Abstract: A controller, for a supercharger-equipped internal combustion engine, that can improve the feedback response of compressor driving force is provided. In a controller, inertial force produced by an inertial moment of a supercharger is calculated, based on a real rotation speed of the supercharger; then, driving force feedback control is implemented in which a gate valve control value, which is a control value for a gate valve actuator, is changed so that an addition value obtained by adding the inertial force to the real compressor driving force approaches a target compressor driving force.

  • Patent number: 9932887
    Abstract: Methods and systems are provided for adjusting flow of exhaust gas from downstream of an exhaust turbine outlet to an exhaust gas aftertreatment device inlet via a compact turbine outlet cone with adjustable swirl vanes. Exhaust flow reaching the exhaust gas aftertreatment device is adjusted based on a desired exhaust gas temperature and exhaust gas flow rate at the aftertreatment device. During cold start conditions, the swirl vanes may be closed to concentrate exhaust gas flowing towards a portion of the aftertreatment device while after attainment of aftertreatment device light-off temperature, the position of the swirl vanes may be adjusted to introduce turbulence and homogeneity to exhaust flow reaching the exhaust aftertreatment device.
