US Patent:

49915584, Feb 12, 1991

Filed:

Jan 3, 1989

Appl. No.:

7/461557

Inventors:

Paul D. Daly - Troy MI
Douglas R. Verner - Sterling Heights MI
Mark A. Brooks - Sterling Heights MI
Robert E. Fallis - Milford MI

Assignee:

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.

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:

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.

Assignee:

Allied-Signal Inc. - Morris Township, Morris County NJ

International Classification:

F16K 3106

US Classification:

25112915

Abstract:

An electro-mechanical fuel injector comprising: a housing and valve seat including a valve setting surface and a metering orifice disposed at a lower end of the housing. An armature assembly is movable relative to the valve seating surface for opening and closing the metering orifice and includes an armature and a pin extending therefrom and adapted to engage the seating surface; a coil assembly and spring are provided to move the armature assembly in a direction to open and close the metering orifice. The injector includes a fluid chamber defined upstream of the metering orifice, in surrounding relation to a portion of the armature assembly. A damping assembly is also provided, movable with the armature assembly, for generating a viscous shear damping force by interacting with the wall of the chamber.
