    摘要： A hydraulic hybrid vehicle includes elements such as a hydraulic pump driven by an internal combustion engine and arranged to draw in low pressure fluid and pump the fluid at high pressure to an accumulator. A hydraulic motor is powered by the pressurized fluid. Safety processes are provided for detecting and addressing a number of conditions that may arise in the operation of the hydraulic hybrid vehicle, including an initialization procedure for start-up of the vehicle, a shut-down procedure, and procedures for detecting and responding to failure of the pump or motor, internal and external fluid leaks, and non-responsive actuation and mode control systems.

    摘要： In a series hybrid vehicle, a system for determining a shift schedule for shifting a multi-gear transmission connected to a drive means is disclosed. A vehicle operator selects among a plurality of shift styles respectively representing a plurality of shift schedules variously optimized for performance or fuel economy. A performance-based shift schedule favors providing maximum power to the road by starting at the first (lowest) gear when accelerating from a stop and utilizing all available gears of the transmission. An economy based shift schedule favors energy efficiency by skipping the first gear and optionally one or more higher-numbered gears in order to bias operation of the drive means toward lower speeds and higher torque output while reducing shift frequency. The invention provides for maintaining the number of gear ratio choices provided by a transmission having relatively many distinct gear ratios, while providing for reduced frequency of shifting and driver choice of a shift schedule favoring either performance or economy.

    摘要： A quasi free piston engine uses, a small, lightweight crankshaft to connect the piston assemblies of the free piston engine with a flywheel. While most of the power output from the combustion pistons is extracted by pumping pistons as hydraulic power, the small crankshaft and flywheel ensure exact TDC position of the combustion pistons in operation, and provide a rotating means to drive combustion cylinder intake and exhaust valves. Flywheel speed may be monitored to provide feedback on power extraction for further control of the system. In addition, a hydraulic push-rod system for efficient valve actuation is provided.

    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 vehicle includes an internal combustion engine configured to power a hydraulic pump to pressurize hydraulic fluid, which is used to power the vehicle directly or is stored in an accumulator. A drive module, including a hydraulic pump/motor and a multi-speed mechanical transmission, is operatively coupled to drive wheels of the vehicle to provide motive power to the vehicle. The drive module can also include a second hydraulic motor (or multiple hydraulic motors) configured to provide motive power. The transmission is configured to progress through its gears at ratio shifts of no less than 2:1 between adjacent gear positions. The transmission is configured to place the hydraulic motor in neutral during some portions of vehicle operation, and to engage the motor during other portions of vehicle operation.

    摘要： A variable displacement engine comprises two engine modules fed from a common fuel source, each engine module having an individual crankshaft. The first engine module has a high compression ratio (e.g., greater than 13:1), while the second module has a typical compression ratio for a gasoline engine (e.g., between 9:1 and 11:1). In one embodiment, the first engine module operates through high efficiency optimized alcohol fuel combustion when the fuel content exceeds a minimum alcohol content. In an alternative embodiment, the first engine module operates at high efficiency through gasoline HCCI combustion when conditions permit. When operating conditions do not permit the first engine module to operate at high efficiency, the second engine module operates as the primary engine module, with the first engine module available to provide supplemental power (at less than optimal efficiency) if needed to meet driver demand.

    摘要： In a bent axis hydraulic machine, a back plate and cylinder barrel vary in distance from a drive plate as a stroke angle of the cylinder barrel changes, thereby minimizing unswept fluid volume in the cylinders of the barrel at any stroke angle. Distance is controlled by one or more rollers, engaging respective tracks that define a profile of contact that determines the distance as a function of the stroke angle. Telescoping fluid supply channels are employed to maintain a fluid supply to the cylinder barrel as the distance changes.

    摘要： A turbocharged engine system is configured to vaporize methanol using heat from exhaust gases and uses the vaporized methanol to drive the engine's turbocharger. The methanol may also be dissociated into hydrogen and carbon monoxide. After passing through the turbocharger, the vapor is injected into the engine by port injection. By selective timing of exhaust valves, the exhaust gases are separated into two streams, a first stream comprising gases ejected during exhaust blowdown, and a second stream of gases ejected during the remainder of the engine's exhaust stroke. The blowdown gases are employed to drive a separate turbine of the turbocharger.
