  • Patent number: 10975790
    Abstract: Systems and methods are provided for using an electric machine as a generator to control boost during an engine cold start. In one example, a method may include receiving a request to increase an engine load during the engine cold start, determining an available capacity of a battery, operating the electric machine as a generator to increase the engine load with an electrical load, and responsive to the available capacity of the battery being less than a charge threshold, charging the battery with the electrical load while generating an increased boost pressure with an electric boosting device by powering the electric boosting device via the battery, and coordinating an amount of the increased boost pressure to compensate the electrical load. By increasing the engine load during the engine cold start, an exhaust gas temperature may be increased to achieve catalyst light-off.

The hydraulic circuit includes a dual displacement motor, which provides high torque for acceleration yet converts to a single motor for high-speed operation. When the exhaust driven turbine function allows compressor speeds, beyond which the hydraulic system can contribute, a slip clutch allows disengagement of the hydraulic drive. The hydraulic circuit is integrated with the power steering circuit to conserve energy and supportive components such as lines and reservoir. In an alternative embodiment, there is no turbocharger and the hydraulic drive provides means of forced induction air alone.

  • Patent number: 8033272
    Abstract: There is provided a method of controlling an engine system having an internal combustion engine, a supercharger arranged in an intake air passage of said internal combustion engine and a motor capable of driving the supercharger. The method comprises, driving the motor to operate the supercharger to boost airflow inducted into the internal combustion engine when the internal combustion engine is in operation. The method further comprises driving the motor to determine a state of the supercharger when the internal combustion engine is stopped and indicating the determined state of the supercharger. According to the method, by driving the motor of the supercharger to detect a state of the supercharger when the internal combustion engine is stopped, the state of the supercharger can be more accurately detected because the condition is most stable.

  • Publication number: 20110174278
    Abstract: An on-off switch is provided between a first battery acting to supply an electric power to on-vehicle electrical equipment and a second battery acting to supply an electric power to an electric supercharger. In the case that charge voltage of the first battery is smaller than a predetermined value and operating power of an electric supercharger 3 is larger than a predetermined value, the on-off switch is opened to suppress electrical effects on the on-vehicle electrical equipment. In other cases, the on-off switch is closed and the second battery is charged by a generator and the first battery. As a result, it is possible to suppress adverse effects on the on-vehicle electrical equipment due to voltage drop or voltage fluctuation of a power source occurring by driving the electric supercharger and thus to make a stable power supply.

  • Publication number: 20110022289
    Abstract: Suitable for retrofitting conventional turbo charged engines, an electrically controlled turbocharger is installed in a Compression Ignition Direct Injection (CIDI) Engine and controlled to maintain a predetermined optimal air/fuel ratio throughout the operating range of the engine. Electrical energy is applied to the motor/generator of the turbocharger to boost its operation when the engine is being operated at relatively low speeds or under high torque loads and the engine exhaust gases applied to the turbine are insufficient to drive the turbocharger to maintain the predetermined air/fuel ratio. Electrical energy is produced by the motor/generator of the turbocharger when the engine is being operated at higher speeds and the engine exhaust gases applied to the turbine are excessive in driving the turbine to maintain the predetermined air/fuel ratio.

  • Publication number: 20100326407
    Abstract: The purpose of the present invention is providing a supercharging system which uses both of a mechanism such as VN or the like and an electric motor generating an assist force while making the supercharger operate smoothly when the assist by the electric motor is stopped. The system controls the electric motor in a feedback manner so that enough assist force is generated (FIG. 2A and FIG. 2B) while controlling the VN in an open manner (FIG. 2D) until status of the supercharger reaches target status (time t1) when an accelerator requirement arises in a low revolution region. The control of the electric motor is changed to an open control, and the control of the VN is changed to a feedback control, respectively, at time t1. The open control of the electric motor is continued so that necessary complement torque occurs until time t2. After time t2, the system maintains the target status only by the feedback control of the VN.

  • Patent number: 7854118
    Abstract: A supercharged internal combustion engine system wherein the supercharger assembly includes an ejector pump driven by high-pressure air for pumping intake air into engine combustion chamber. Included are means for sensing engine power demand and controlling the supercharging action. A compressor and an air tank for providing high-pressure air for driving the ejector pump are also disclosed. During periods of natural aspiration the ejector pump can be by-passed to reduce flow impedance. The ejector pump can use a driving nozzle with a fixed throat or a variable throat, or a lobed nozzle. Effective supercharging is achieved even at low engine speeds. One of the objects of the invention is to obtain more power from small displacement ICE and thus providing automotive vehicles with sufficient acceleration in addition to good fuel economy.
