Appl. No.:

09/919005

Inventors:

Bryan T. Jett - Lowell MI
Hans-Joachim Schulz - Grand Rapids MI
David Huber - Hudsonville MI

Assignee:

Diesel Technology Company - Kentwood MI

International Classification:

G01M 1500

US Classification:

73119A

Abstract:

A method for calibrating a fuel injection pump for an engine fuel injection system comprising determining the pressure made available to an injector nozzle at a portion of the injection cycle before the top dead center position of the engine crankshaft. A solenoid-operated control valve establishes a rate of fuel delivery through the injector nozzle. The method calculates a boot current for the valve, which will achieve optimum pressure delivery through the nozzle. An electronic controller for the injection system calibrator relies upon an algorithm to find the lowest and the highest boot current level that will achieve injector stability. The logic of the system will increase the precision of the boot current by repeated substitution of incremental current values to determine an upper limit and a lower limit for the boot current.

International Classification:

F02F 1/00

US Classification:

1231932, 1231933, 1231934

Abstract:

A power assembly for an internal combustion engine includes a cylinder with a circular wall defining a first inside diameter. A piston is reciprocably housed within the cylinder. An integral, unitary piston deposit scraper is formed in a portion of the circular wall of the cylinder by upsetting a portion of the metallic wall so as to configure a piston scraper with a second inside diameter which is less than the first inside diameter. The inside diameter of the piston scraper closely matches that of the outside diameter of the top land of the piston. As a result, the piston scraper removes combustion deposits from the piston each time it moves into the top dead center position.

International Classification:

B61C 1/00
F02M 37/04

US Classification:

105 2605, 123501

Abstract:

A railroad locomotive includes a naturally-aspirated reciprocating internal combustion engine, and a traction generator driven by the engine. A throttle position sensor produces a signal corresponding to the throttle position selected by the locomotive's operator. A load regulator receives a speed signal derived from the throttle position signal and outputs an excitation signal for the traction generator which is modified by a controller in response to air availability so that engine speed and load are controlled independently of the selected throttle position, so as to limit the exhaust smoke output of the engine.

International Classification:

B61C 17/00

US Classification:

105 2605

Abstract:

A railroad locomotive includes a naturally aspirated reciprocating internal combustion engine driving a traction generator. A speed control system and load regulator provide an output signal which is operated upon and modified by a controller in response to the barometric pressure at which the locomotive is being operated.

Inventors:

Manoj Prakash Gokhale - Bangalore, IN

Assignee:

General Electric Company - Schenectady NY

International Classification:

F02M 55/02

US Classification:

123468, 123575, 123576, 123510, 123511, 123544

Abstract:

An improved high viscosity fuel injection pressure reduction system and method is disclosed for use in an internal combustion engine. The system may include a first fuel line and a second fuel line. The first fuel line may be configured to be coupled upstream of a combustion chamber of the engine when the engine is operated with the first fuel and to provide a first pressurized volume when installed. Likewise, the second fuel line may be configured to be coupled upstream of the combustion chamber of the engine when the engine is operated with the second fuel and to provide a second pressurized volume when installed. The first and second volumes of the fuel lines may provide peak injection pressures lower than a desired pressure when the engine is operated with the first and second fuels, respectively.

Appl. No.:

9/265683

Assignee:

Diesel Technology Company - Kentwood MI

International Classification:

F02M 3704

US Classification:

123446

Abstract:

Pumps and injectors utilize a control valve having a valve body with a valve stem having a step adjacent to the seating surface. The step extends a limited distance away from the seating surface to provide limited pressure relief when the valve body is at an intermediate position that is between the opened and closed positions. Step cross-section and axial length may be configured based on desired hydraulic behavior. In a preferred embodiment, the control valve step is configured for injection rate shaping.
