20130081889TWIN ENGINE FOR IMPROVING FUEL EFFICIENCY AND METHOD OF OPERATING ENGINE USING THE SAME - A twin engine improves fuel efficiency in a low-load section and generates sufficient output in a high-load section by selecting a specific bank or operating all of the banks in accordance with necessity of required load. The twin engine may include a plurality of engine banks that independently operates in a unit of a cylinder block equipped with a plurality of cylinders, transmissions that are provided at the same number of engine banks and disposed between output ends of engine banks, a power controller that selectively collects the power output from the output ends of transmissions and transmits the power to driving wheels, and a driving controller that controls the operations of the engine banks and the power controller, such that the engine banks are selectively or simultaneously operated in accordance with traveling conditions.04-04-2013
20080236919Electric grid for an electric machine - An electric machine including an engine, generator, and motor. The electric grid is positioned between an input passage and output passage of an exhaust system of the engine. While in retard mode, excess electric power is dumped to the electric grid. Continuous airflow from the engine through the exhaust system removes the energy, in the form of heat, away from the electric grid.10-02-2008
20110203863MULTI-POWER OUTPUT DEVICE FOR VEHICLE DRIVING SYSTEMS - The present invention discloses a multi-power output device for vehicle driving systems, which propels a vehicle having at least one wheel and comprises a primary power output device, a primary speed-change device, at least one auxiliary power output device, at least one auxiliary stepless speed-change device and at least two transmission devices. The primary power output device and the at least one auxiliary power output device respectively output driving power. The primary speed-change device, auxiliary stepless speed-change device and the transmission devices are coupled to drive the wheels to rotate and propel the vehicle to move. The present invention uses the primary power output device and the auxiliary power output devices to output driving power and uses the auxiliary stepless speed-change devices and the primary speed-change device to change the rotation speed of the driving power to output severalfold horse power to upgrade the acceleration capability of the vehicle.08-25-2011
20110232984Independent axle drive - The presented application is used to power an electric vehicle using this efficient and compact method of transmitting rotational power within a single compact enclosure. The unforeseen positive byproducts from this system of transmitting rotational energy are flywheel and gyroscopic energies.09-29-2011
20090242301Efficient Vehicle Power Systems - The present disclosure teaches a fuel efficient method for powering a vehicle. The total peak power requirements for a moving vehicle under a set of performance criteria are divided into at least two subgroups. A primary engine is provided with a size and output to provide for the peak power for one of the at least two subgroups and one or more auxiliary engines or auxiliary engine subsystems are provided with a size and output to provide for up to the peak power for the remaining one or more subgroups.10-01-2009
20100038162AUTOMOTIVE CONSTRUCTION MACHINE - A ureal water tank (02-18-2010
20080223640Methods and Devices for Altering the Transmission Ratio of a Drive System - The transmission ratio between a first motor and an output shaft is varied by changing the speed of a second motor. The first and second motors are coupled to the output shaft with a planetary gear set. The first and second motors may both add power to the drive system.09-18-2008
20100032222Auxiliary Power Units For Vehicles - Cooperative operation of an auxiliary power unit having a mechanical power output shaft with a transmission coupled power takeoff operation system of a vehicle is provided by allowing the vehicle's main engine to be cranked by the auxiliary power unit through the power takeoff operation system.02-11-2010
20120111655ELECTRIC RIDE-ON MOWER - This invention provides an electric ride-on mower that can easily lift up and down the mower deck and can also lift up and down the mower deck so that it remains horizontal. The electric ride-on mower has driving motors, mower blades spinning for mowing grass, mowing motors for the mower blades, batteries for the driving motors and the mowing motors, a mower deck for covering the mower blades from the above and sides and for setting the mowing motors on, and a mower deck lifting device for lifting up and down the mower deck, wherein: the mower deck lifting device has a booster for assisting the mower deck lifting device in lifting up and down the mower deck, and the mower deck lifting device is set at the center on the mower deck.05-10-2012
20090288899Vehicle with multiple engines coupled to a transmission via a jackshaft - A motor vehicle is provided with a power train having primary and auxiliary internal combustion engines which selectively feed power to a jackshaft. The power accumulated in the jackshaft is conveyed to a speed change transmission. Fuel economy is achieved by utilizing only one engine when lesser power is needed by the vehicle.11-26-2009
20120125705VEHICLE - A vehicle includes a PCU serving as a power control unit controlling the electric power for vehicle running, a battery storing the electric power for vehicle running, and an EHC serving as an electrically heated catalyst. The PCU includes a converter, an inverter, and a positive line and a negative line each connecting the converter and the inverter. The converter boosts a voltage VL output from the battery to a requested voltage value VHsys. The EHC has a positive end connected to the positive line. The EHC also has a negative end connected to the negative line.05-24-2012
20120073890Multi-Worm Circle Drive Gearbox - A work vehicle comprises a frame, a circle gear mounted to the frame to rotate relative thereto, a moldboard coupled to the circle gear to rotate therewith, and a circle drive gearbox comprising gearing, a first worm, and a second worm, the gearing meshing with the circle gear, the first and second worms meshing with the gearing.03-29-2012
