International Classification:

F02P 1900
F02B 908

US Classification:

123298

Abstract:

A fuel injector, system and method comprising means for ejecting fuel directly into a cylinder (14) an engine through a non-conductive, heat storing element. The element including a nozzle (44) portion comprising a preferably ceramic body having a narrow, first passage (158) in communication with a conical second portion (164). The two portions cooperating to cause the fuel to flow turbulently therethrough. The nozzle further includes a heater (174) for elevating the temperature to the nozzle to a predetermined temperture. In this manner, as the fuel contacts the heated nozzle it is atomized. In one embodiment of the invention a solid ceramic body is employed. In another embodiment, the nozzle (178) is formed by a plurality of stacked ceramic disks which include a central opening (182) therethrough and a plurality of heating elements (184), one for each disk. The openings (182) are sized to approximate the continuous conical portion of the solid body nozzle. A control (45) is provided for electrically heating the nozzle (44,178) during certain operating intervals of the engine and a method of operating the engine is described which permits the removal of the electrical energy and permits the nozzle to thereafter be heated by the heat of the combustion process in the cylinder.

Siemens Automotive L.P. - Troy MI

International Classification:

F02D 700

US Classification:

123481

Abstract:

A multiple cylinder two-stroke fuel-injected internal combustion engine is operated at idle by interrupting the fuel injection stages in a predetermined pattern such that over a certain number of crankshaft revolutions a fewer number of injections occur than over the same number of revolutions at non-idle. The quantity of fuel injected per injection is increased relative to that required to operate the engine at idle wihtout any injection interruptions. Spark timing is also advanced.

Assignee:

Siemens Automotive L.P. - Auburn Hills MI

International Classification:

F02M 5106
F02M 6113

US Classification:

2395854

Abstract:

The fuel injector has several swirl passages in a fuel swirl and needle guide member that direct swirl fuel onto the frusto-conical surface of a valve seat member that is disposed at the injector's nozzle end. The needle lift is such that with the needle unseated to open the injector to flow, the swirl fuel is throttled as it passes between the rounded tip end of the open needle and the frusto-conical surface of the seat member. The throttling tends to spread the swirl flow so that it is more uniform in the circumferential sense. If the injector is closed before equilibrium flow occurs, a toroidal shaped fuel cloud is created; if the injector is closed after equilibrium flow occurs, an ellipsoidal shaped fuel cloud is created.

Abstract:

A reversible flow pump (12) comprising: a first port (16) and a second port (20); a rotor (60) comprising a plurality of pump elements (74-80) movable through a fill mode and a discharge mode, a pump chamber (140) associated with each pump element (74) which are respectively filled and discharged; a ported shaft (30) rotatable between a first position and a second position, for carrying fluid to and from the various pump chambers (140), such that when in the first position fluid received at the first port (16) is communicated to fill each pump chamber (140) during the fill mode, at least a portion of such fluid is discharged therefrom and communicated to the second port (20), and wherein in the second position fluid flow is reversed. A brake system incorporating the pump is also disclosed.

International Classification:

F02B 7502

US Classification:

123 65A

Abstract:

A method and system, including a valve (32) for controlling the amount of fluid purged from a cylinder (12) of a two-cycle engine prior to the combustion of an air-fuel mixture within the cylinder especially during low demand periods of engine operation. The system including a throttle (26) disposed upstream of an inlet port (14) and controlled to be maintained in an open condition during such intervals. The valve (32), which is adapted to communicate with a scavenge port (30) includes a piston (80) that is movable relative to an aperature (76) in response to a pressure differential created in part by the operation of a cooperating electromagnetic valve (54), such that when the piston is moved to uncover the aperture a predeterminable amount of fluid within the cylinder can be purged therefrom as the cylinder piston is moved through its compression cycle.
