摘要： To reduce emissions at higher engine loads and speeds, methanol fuel is port-injected with charge-air into a diesel engine, and diesel fuel is then direct-injected to initiate combustion. The charge-air has a reduced oxygen concentration sufficient to prevent pre-ignition of the methanol prior to injection of the diesel fuel, and to reduce NOx formation. At low engine speeds and loads, the engine may run on diesel fuel alone.

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 fuel injector nozzle for use with an internal combustion engine utilizes arrangements of nozzle openings that are designed to increase fuel contact with oxygen within a combustion chamber. Nozzle openings are positioned in more than one plane substantially parallel with the cylinder head surface, with the planes preferably at least 2 millimeters apart, and with the respective pluralities of nozzle openings oriented to provide diverging injection angles in relation to the cylinder head surface. The fuel injector is particularly designed for use with oxygen-dilute (e.g., high EGR) controlled temperature combustion, direct injection compression ignition engines.

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.
摘要翻译：可变排量发动机包括从共同燃料源供给的两个发动机模块，每个发动机模块具有单独的曲轴。第一发动机模块具有高压缩比（例如大于13:1），而第二模块具有用于汽油发动机的典型压缩比（例如在9:1至11:1之间）。在一个实施例中，当燃料含量超过最低酒精含量时，第一发动机模块通过高效优化的醇燃料燃烧进行操作。在替代实施例中，当条件允许时，第一发动机模块通过汽油HCCI燃烧以高效率运行。当操作条件不允许第一发动机模块以高效率运行时，第二发动机模块作为主要发动机模块运行，如果需要满足驾驶员需求，第一发动机模块可用于提供补充功率（不到最佳效率）。

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.

摘要： A fluid bearing includes hydrostatic pads formed in a surface and positioned to exert a separating force, and a land formed on the surface of the insert and configured to act as a bushing to allow rotation while the first and second pads are pressurized at less than a hydrostatic balance force. Pressurized fluid to the pads of the insert is controlled to prevent operation in full hydrostatic mode. More particularly, a separating force generated by surface force of the pads is controlled such that the separating force does not exceed a force exerted on the bearing. The fluid pressure is also controlled to keep the separating force within a selected margin of the force exerted on the bearing, to control wear of the bearing. Control of the separating force is achieved by selectively pressurizing individual hydrostatic pads, thereby effectively varying the active hydrostatic area of the bearing.
摘要翻译：流体轴承包括形成在表面中并定位成施加分离力的流体静力垫，以及形成在插入件的表面上并且构造成用作套筒以允许旋转的平台，同时第一和第二垫在小于静水平衡力。加压流体到插入件的垫被控制以防止在完全静液压模式下操作。更具体地，控制由垫的表面力产生的分离力，使得分离力不超过施加在轴承上的力。还控制流体压力以将分离力保持在施加在轴承上的力的选定余量内，以控制轴承的磨损。分离力的控制通过选择性地加压各个静压垫来实现，从而有效地改变轴承的主动静水压面积。

摘要： A vehicle includes an integrated drive module coupled to an axle thereof. The module includes a hydraulic motor configured to provide motive power at an output shaft, and a differential for distributing the motive power to right and left portions of the axle. The hydraulic motor and the differential are encased within a common housing. The vehicle may include a second integrated drive module having, within a housing, a second hydraulic motor (or multiple hydraulic motors), and a second differential coupled thereto and configured to distribute motive power to right and left portions of a second axle. The second module may also include a transmission within the same housing. The transmission may be a two speed or other multi-speed transmission. The second module is configured to operate in neutral while power demand is below a threshold, and to engage while the power demand exceeds the threshold. The second module may be configured to remain engaged for full-time four-wheel-drive operation.

摘要： An actuator includes a piston within a cylinder, the cylinder having a first fluid port in communication with an open side of the piston, and a second fluid port in communication with a shaft side of the piston. The piston travels in a first direction, toward the shaft side of the piston and in a second direction, toward the open side of the piston. The actuator includes a valve circuit configured to selectively couple the first fluid port with a high-pressure fluid source when piston travel in the first direction is desired, and with a low-pressure fluid source when piston travel in the second direction is desired. The valve circuit is further configured to couple the second fluid port to the high-pressure fluid source when piston travel is desired in the first or second direction, and to close the first and second fluid ports when no piston travel is desired.

摘要： A hydraulic accumulator includes a rigid tank containing a flexible but non-elastic bladder formed of a metal foil and separating the interior of the tank into a gas space and a liquid space. The gas and liquid spaces respectively communicate with exterior sources of gas and liquid through fixtures provided on the accumulator tank. One of the fixtures is provided with an anti-extrusion valve to prevent the bladder from being forced out through the fixture. In one preferred embodiment the bladder is a bellows. In another preferred embodiment the accumulator tank is provided with a vent in communication with the liquid space within the tank to allow for venting of any gas separating from the liquid and accumulating within the liquid space.
