    摘要： The invention relates to an apparatus and method of statically sealing a reciprocating-type fuel pump, such as a direct injection high pressure piston-type fuel pump. The first embodiment of the invention is a fuel pump comprising a pump body, a fuel reservoir within the pump body, wherein the fuel reservoir is capable of holding fuel and a bellows attached to the pump body, wherein the bellows is a stretchable membrane acting as a static seal. The second embodiment further comprises a diaphragm seal inside the pump body, and adjacent to the fuel reservoir, and a working fluid reservoir adjacent to the diaphragm seal, wherein the working fluid reservoir is capable of holding fluid. The diaphragm seal is a static seal separating the working fluid reservoir and the fuel reservoir.

    摘要： A valve actuator assembly for an engine includes a movable poppet valve, and movable first and second spool valves. The assembly also includes an intermediate channel interconnecting the first and second spool valve, a driving channel, and a first and second feedback channel interconnecting the second spool valve and the poppet valve. The valve actuator assembly includes an actuator cooperating with the first spool valve to position the first spool valve to selectively allow high pressure fluid flow to the second spool valve and the driving channel to position the engine valve. The valve actuator assembly further includes a first and second on/off valve in respective fluid communication with the first feedback channel and the second feedback channel to selectively exhaust the first and second feedback channel to control motion of the second spool valve. The second spool valve includes a detent feature operable to maintain the second spool valve in a center biased position.

    摘要： An internal combustion engine includes a crankshaft and first and second cam actuated intake valves. A method for operating the engine includes providing a first intake cam configured to actuate the first cam actuated intake valve, and providing a second intake cam configured to actuate the second cam actuated intake valve. The second intake cam is phase adjustable relative to the crankshaft independently of the phase of the first intake cam relative to the crankshaft. A controller is provided and configured to selectively retard the phase of the second intake cam to effect later closing of the second cam actuated intake valve sufficiently to reduce the effective compression ratio of the engine. Additionally, the first intake cam may be phase adjustable relative to the crankshaft independently of the phase of the second intake cam relative to the crankshaft and the controller may additionally be configured to selectively advance the phase of the first intake cam to effect earlier opening of the first cam actuated intake valve sufficiently to increase internal exhaust gas recirculation.

    摘要： A method for a multi-fuel vehicle includes: determining a first target amount of fuel to be injected for a combustion event of a combustion chamber of an engine; determining first and second fractions for the combustion event based on at least one of engine speed, engine load, and engine temperature; determining a second target amount of liquid fuel for the combustion event based on the first target amount and the first fraction; determining a third target amount of gaseous fuel for the combustion event based on the first target amount and the second fraction; selectively injecting a liquid fuel directly into the combustion chamber for the combustion event based on the second target amount and using a first fuel injector; and selectively injecting a gaseous fuel into a port of the combustion chamber for the combustion event based on the third target amount and using a second fuel injector.
