  • Patent number: 10174719
    Abstract: In a non-EGR region that is a light load operating region, an EGR control valve (21) is opened at a predetermined infinitesimal opening degree M that corresponds to such infinitesimal EGR ratio as not to affect an ignition timing. With this control, since an EGR passage (20) is basically in a state in which the EGR passage (20) is filled with EGR gas, when an operating condition is changed from the non-EGR region to an EGR region and the EGR control valve (21) is opened so as to gain a target EGR ratio, a desired quantity of the EGR gas is introduced into an intake passage (2) substantially at the same time as the opening of the EGR control valve (21). An actual EGR ratio can thus follow the target EGR ratio with a good response.

  • Patent number: 10012167
    Abstract: An ECU loads detected values of a rotation angle sensor and a pressure sensor which are mounted to an electric throttle, and executes an abnormal-sensor determination control to determine whether one of the rotation angle sensor and the pressure sensor is abnormal. Specifically, the ECU determines that one of the rotation angle sensor and the pressure sensor is abnormal, in a case where a state that a tendency of the actual opening angle detected by the rotation angle sensor does not match a tendency of the pressure detected by the downstream pressure sensor has continued for a period greater than or equal to a predetermined period. Therefore, since the pressure sensor can replace the rotation angle sensor used for detecting abnormality in a conventional technology, two rotation angle sensors can be reduced to one rotation angle sensor, and a cost is reduced.

  • Patent number: 9956946
    Abstract: A method and system for cleaning a brake booster aspirator shut-off valve are provided. The shut-off valve is operable to selectively permit flow of intake air through an aspirator; the aspirator bypasses a throttle of an engine and provides a vacuum source for a brake booster. The method comprises determining whether the shut-off valve may require cleaning, opening the shut-off valve so as to permit a flow of air through the shut-off valve and clean the shut-off valve and adjusting the throttle position of the engine to compensate for the additional flow of intake air through the aspirator.

    Abstract: A multi-speed drive for a supercharger includes a planetary gear mechanism with a sun gear mechanism, a plurality of planet gears mounted on a planet carrier, and a ring gear, all mounted for rotation on a stationary shaft. A rotary-mechanical drive input is received by either the ring gear or the planetary drive, and a rotary-mechanical drive output is provided by the planetary drive when the ring gear receives the input, or by the ring gear when the planetary drive receives the input. A one-way roller clutch is disposed coaxially with the planetary gear mechanism, between the sun gear mechanism and the stationary shaft. A hydraulically-actuated, clutch assembly mounted coaxially with the planetary gear mechanism on the stationary shaft engages the sun gear and the ring gear to change the gear ratio of the drive.
