  • Patent number: 9481371
    Abstract: A method and apparatus for controlling a speed change of a hybrid vehicle are provided. The apparatus includes an engine for combustion of fuel to generate power and a motor that is configured to supplement the power from the engine and operate as a generator during braking to generate electrical energy and store the generated electrical energy generated a battery. A transmission is configured to convert the power from the engine to a required torque based on a speed and transmit the power to wheels and is directly connected to the motor. In addition, a controller is configured to operate the transmission to shift in a constant power section of the motor when the motor is performing regenerative braking. The apparatus minimizes the sense of difference felt by a driver by shifting in the constant power section of the motor during the regenerative braking of a hybrid vehicle.

  • Patent number: 9334833
    Abstract: A turbocharger system for ensuring a sufficient exhaust gas recirculation (“EGR”) amount in all operating conditions, and reducing NOx emission from an engine. The system includes an EGR controller that re-circulates a part of exhaust gas discharged from the engine to an intake side. The turbocharger is a power-assisted turbocharger including an electric motor that assists a drive force of a compressor. The EGR controller controls an amount of exhaust gas recirculated to the intake side so as to inhibit the generation of NOx regardless of an amount of oxygen necessary for combustion of the engine. An electric motor control unit drives the electric motor, by the control of the EGR controller, when the amount of oxygen necessary for the combustion of the engine is deficient.

  • Patent number: 9297341
    Abstract: Systems and methods are provided for engine systems including a multiple tap aspirator with a throat tap and a diffuser tap. Suction passages coupled to the throat and diffuser taps, respectively, may fluidly communicate via a leak passage with a flow restriction. During conditions where the pressure at a suction flow source of the diffuser tap is less than the pressure at the diffuser tap, backflow from the diffuser tap may travel through the leak passage into the throat tap.

  • Patent number: 9151266
    Abstract: Improvements in an ocean wave energy conversion unit that converts kinetic energy from oceanic waves into useable form of energy that will benefit society called and Aqua-tamer. The unit is designed to be modular in nature where the units can be deployed to function individually or assembled into groups where units will rely on each other and function together as a whole. Each individual unit has an electrical output. As a group (Colony) during deep sea surface applications, the electrical output of each Aqua-Tamer unit will be consolidated and used to operate a water-electrolysis operation that produces Oxygen Gas (O2) and Hydrogen Gas (H2). This production of O2 and H2, instead of electrical output, is designed to eliminate the requirements of an Ocean-wide electrical grid system and still facilitate an economic logistically efficient) method of energy transportation (energy in a gas state.
