Appl. No.:

6/942526

Inventors:

Mark A. Brooks - Sterling Heights MI

Assignee:

Allied Corporation - Morris Township, Morris County NJ

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.

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.

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.

International Classification:

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.

Abstract:

A pressure sensor including a pressure capsule such as a dual diaphragm quartz capacitance pressure capsule. The pressure capsule having two parallel quartz plates spaced by a dielectric ring forming a vacuum chamber therein. A registration fixture is described which contains a plurality of flat plates, each plate having a pressure capsule receiving cavity sized to closely receive one of the quartz plates and further provides a uniform temperature radiation pattern for sealing of the pressure capsule during the controlled pressure-temperature profile.

Abstract:

A pressure sensor including a pressure capsule such as a dual diaphragm quartz capacitance pressure capsule and structure for supporting and sealing same within the pressure environment to be measured. The pressure capsule having two parallel quartz plates spaced by a dielectric ring forming a vacuum chamber therein. The structure providing a force balanced support for compressively loading the pressure capsule through the dielectric ring. The structure further having transfer port therein to communicate the pressure environment to both plates. The method of making the quartz capacitive pressure capsule includes the steps of surface preparation, preglazing of the component parts and vacuum cooling by utilizing a controlled pressure-temperature profile. A registration fixture is described which contains a plurality of flat plates, each plate having a pressure capsule receiving cavity sized to closely receive one of the quartz plates and further provides a uniform temperature radiation pattern for sealing of the pressure capsule during the controlled pressure-temperature profile.

Abstract:

A high pressure vortex fuel injector comprising a hollow housing or body including a plurality of passages at least one of which is adapted to receive fuel through an inlet. The injector also includes a passage for guiding the piston into seating relationship with the valve seat to control the flow of fuel through the metering orifice and a solonoid assembly for moving the piston relative to the valve seat. The injector further includes a swirl or vortex chamber, to angularly accelerate the fuel, formed in cooperation with the first surface of the valve seat. The injector additionally includes passages for permitting fuel to circulate about an electric coil thereof, thereby cooling same during instances when the metering orifice is closed. The injector further includes passages within the swirl chamber for assisting in the rapid formation of a conical spray pattern upon the opening of the metering orifice.
