摘要： A turbocharger system includes first and second turbines arranged such that exhaust gas passes through the first turbine then the second turbine. A bypass channel is configured such that exhaust gas entering the channel passes only through the second turbine. A valve positioned in the bypass channel regulates the flow of gas therethrough. The valve accelerates a stream of gas and focuses the stream toward the second turbine such that a large part of the added velocity of the stream is preserved as it enters the second turbine. Operation of the valve may be controlled so as to maintain the valve in a closed position while exhaust gas pressure above the first turbine pressure is below a first threshold, to progressively open the valve as the pressure increases above the first threshold, and to maintain the valve in a full-open position while the pressure is above a second threshold.

摘要： A hydraulic manifold has features adapted to the needs of hybrid vehicle applications. In one embodiment, multifunction valves selectively regulate fluid flow among primary and auxiliary flow paths. A normally closed butterfly valve is biased by a relatively small secondary biasing force against rotation in first and second (opposite) directions, and by a relatively large principal biasing force against rotation in the first direction past a transitional angular position at which the principal biasing force takes effect. An actuator selectively controls the transitional angular position and the magnitude of the principal biasing force. In the first direction, flow must overcome only the secondary biasing force to pass the valve. In the second direction, any flow sufficient to overcome the secondary biasing force but not the principal biasing force will divide into a first flow passing the valve and a second flow induced to enter an auxiliary path upstream. Additional flow causing the principal biasing force to additionally be overcome will substantially pass the valve as part of the first flow. This and other embodiments provide a manifold that is controllable to allocate flow among primary and auxiliary paths while remaining responsive to sudden large changes in flow independently of immediate control response.

摘要： A fluid power system includes a hydraulic machine. A pilot-controlled supply valve controls high-pressure fluid to the machine. The valve is coupled between the hydraulic machine and a high-pressure fluid source, and includes a control port for an actuation signal. The supply valve allows passage of fluid from the machine to the fluid source, but blocks passage of fluid from the fluid source to the machine while closed, or permits passage of fluid from the fluid source to the machine while open. The supply valve biases toward closed or open according to an actuation signal at the control port. A pressurization valve is also coupled between the hydraulic machine and the high-pressure fluid source. The pressurization valve blocks passage of fluid from the fluid source to the machine while in a first position, and allows a restricted passage of fluid between its input and output ports while in a second position, to allow pressure to equalize on either side of the supply valve before the supply valve opens.

摘要： A hydraulic pressure accumulator has an interior chamber containing a fire-suppressing gas such as nitrogen. The fire-suppressing gas in the accumulator is fluidly connected to a thermal device, such as a valve with a thermal fuse or a controlled valve triggered by a thermal sensor. The thermal device is designed to open a fluid connection between the accumulator's interior chamber to ambient when the exterior temperature exceeds a determined safety threshold, thereby releasing the fire suppressing gas from the accumulator.

摘要： A method for operating a series hybrid vehicle in a manner that responds to an operator's demand for power output, while maximizing engine efficiency and minimizing disruptions in vehicle drivability, may include determining, when the operator makes a demand for power output, whether the secondary power source(s) is supplied with secondary energy stored in an energy storage device(s), direct input energy generated by an engine(s), or both, based on an amount of available secondary energy stored in a secondary storage device(s) alone, or in combination with vehicle speed. While the engine is generating secondary energy, the power efficiency level at which the engine operates may depend on the amount of available stored secondary energy alone, or in combination with vehicle speed. Further, when the engine is not generating secondary energy, the engine may be selectively turned off or idled in response to various operating conditions.

摘要： A fuel injection supply system includes an intensifier cylinder having an intensifier piston configured to pressurize fuel in an intensifier chamber of the cylinder during a pressurizing stroke, and further configured to draw fuel into the intensifier chamber during a recharge stroke. A fuel rail receives pressurized fuel from the intensifier chamber, and supplies the fuel to a plurality of fuel injectors. A control unit controls switching of the intensifier piston between a pressurizing stroke and a recharge stroke, controlling recharge strokes of the piston to occur between two consecutive injection events of the plurality of fuel injectors. The common fuel rail may be hydraulically locked except during injection events of any of the plurality of fuel injectors, or during a recharge stroke of the piston. The intensifier piston may be controlled to perform a recharge stroke once during each engine cycle, or more than once during each engine cycle.

摘要： The invention is directed toward methods for operating a series hybrid vehicle in a manner that responds to the operator's demand for power output, while maximizing engine efficiency and minimizing disruptions in vehicle drivability. According to principles of the present invention, when the driver of a series hybrid vehicle makes a demand for power output, whether the secondary power source(s) is supplied with secondary energy stored in an energy storage device(s), direct input energy generated by an engine(s), or both, depends on the amount of available secondary energy stored in the vehicle's secondary storage device(s) alone, and in combination with vehicle speed. During the time that the engine is used to generate secondary energy, the power efficiency level at which the engine is operated also depends on the vehicle speed and the amount of available secondary energy stored in the vehicle's secondary storage device alone, and in combination with vehicle speed. Further, in some embodiments, when the engine is not generating secondary energy, the engine is selectively turned off or idled in response to various operating conditions.

摘要： A vehicle drive-train includes a drive-motor having an output shaft and a transmission having an input shaft, an output shaft, a plurality of discrete forward gear ratios and a corresponding plurality of synchronizers. Each of the synchronizers is configured to mechanically synchronize rotation of the drive-motor output shaft with the transmission output shaft according to a value of a selected gear ratio, during shifting of the transmission to the selected gear ratio. The output shaft of the drive-motor and the input shaft of the transmission are coupled together such that, during normal operation of the drive-train, rotation of the output shaft of the drive-motor results in a proportionate and uninterrupted rotation of the input shaft of the transmission.
