  • Patent number: 8820056
    Abstract: Disclosed is a super-turbocharger system that increases power and efficiency of an engine. The system uses the exothermic properties of a catalytic converter to extract additional energy from exhaust heat that is used to add power to the engine. Compressed air is supplied and mixed with exhaust gases upstream and/or downstream from a catalytic converter that is connected to an exhaust manifold. The gaseous mixture of exhaust gases and compressed air is sufficiently rich in oxygen to oxidize hydrocarbons and carbon monoxide in the catalytic converter, which adds heat to the gaseous mixture. In addition, a sufficient amount of compressed air is supplied to the exhaust gases to maintain the temperature of the gaseous mixture at a substantially optimal temperature level. The gaseous mixture is applied to the turbine of the super-turbocharger, which increases the output of said super-turbocharger, which increases the power and efficiency of said engine.

Even when a temperature (ambient temperature) in the engine room detected by a temperature sensor (47b) rises up to an upper limit temperature (upper limit ambient temperature) of the ambient temperature, if a temperature (driver temperature) of a portion of the driver (41) that has a highest temperature detected by a temperature sensor (47a) is yet to rise to an upper limit temperature (upper limit internal temperature) of the driver temperature, the control device (51) causes the rotary motor (20) to continue to drive as the motor while lowering an upper limit of an output current.

  • Patent number: 8413439
    Abstract: A power supply of equipment onboard a motor vehicle equipped with a micro-hybrid system that can operate in a regenerative braking mode during which the energy recovered by a reversible rotary machine (1) of the micro-hybrid system is stored in an auxiliary energy storage unit (4). The micro-hybrid system provides a dual-voltage network including, on the one hand, a low voltage (Vb) for supplying a battery (3) of the vehicle and, on the other hand and at the terminals of said auxiliary energy-storage unit, a floating voltage (Vb+X) higher than the low voltage. The floating voltage (Vb+X) is used for powering the onboard equipment of the vehicle that may require high currents during short periods of time for the dynamic operation thereof. The power supply is particularly useful for powering an electric-assistance turbocharger.

  • Patent number: 8393152
    Abstract: An lubricating oil from an oil pump that is driven by rotation of an engine is supplied as a refrigerant to a rotor of an assist motor via a pressure valve. The pressure valve is configured to be closed when the pressure of the lubricating oil is less than a predetermined value, and to open when the pressure of the lubricating oil is greater than or equal to the predetermined value. As a result, when the rotor is in low need for cooling down because the temperature rise of the rotor is small although the rotation speed of the rotor rises, that is, when the engine is operating at a low rotation speed with a high load, the supply of lubricating oil to the rotor is reduced or stopped.

  • Publication number: 20120266595
    Abstract: A hydraulic drive assists to increase the acceleration rate of a turbocharger impeller/turbine shaft assembly and provide a secondary means of driving the compressor impeller at lower engine speeds where exhaust gases alone does not generate adequate shaft speeds to create significant induction boost. 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.
