Abstract: Disclosed is a fuel injection mechanism having a horizontal control surface formed within a plunger for regulating the start of fuel injection. The horizontal control surfaces are formed within one or more of the two opposed ridges formed within the plunger defining a recessed channel there between. The horizontal control surfaces of the ridges regulate the opening and closing of the ports formed within the bushing of the injector. The horizontal control surfaces contribute to reduced wear and provide for accurate timing and fuel quantity delivery.

Abstract: Disclosed is a nameplate which can provide both part and manufacturer information and timing guidance is a functional identification nameplate for a diesel fuel injector. The nameplate is attached to the top of the injector body and provides an alternative to the practice of re-machining the injector body's front face to remove past information in the remanufacture of the injector. Additionally, the nameplate serves as a functional static timing reference indicator in providing a vertical riser extending up from the top of the injector.

Abstract: Disclosed is an electronic module designed to use the locomotive engine's speed sensors to detect such changes in engine speed (rpm), as required by the locomotive operator moving the throttle notch handle. Once a speed change is detected, the module commands an air valve on each of the locomotive's main air reservoir tanks, (designed to handle the normal operating main reservoir air pressure), to open and allow them to discharge into the engine's intake manifolds located on both sides of the diesel engine.

Abstract: Disclosed is a fuel injection nozzle assembly comprising a poppet type valve assembly capable of producing a circumferential spray pattern. The fuel injection nozzle assembly includes a nozzle body defining a valve outlet into which is fitted a needle valve having a flanged portion extending from the nozzle body. The flanged portion opens and closes the valve outlet as the needle valve travels up and down the nozzle body as dictated by the fuel pressure within the nozzle body. The flanged portion may further direct the fuel spray into a combustion chamber.

Abstract: Disclosed is a fuel injection mechanism for regulating the volume of fuel injected into a cylinder comprising a selectively detachable helix ring configured to be removably affixed to an outside diameter of a plunger. The selectively detachable helix ring includes a ridge that has at least one helix angle. The helix angle is associated with a throttle position of the mechanism.

Abstract: A skipfire control system for use in a locomotive engine includes a plurality of skipfire mechanisms. Each skipfire mechanism is operatively associated with a respective injector rocker arm of the plurality of cylinders of the engine. Each skipfire mechanism includes an actuator movable between an inoperative position wherein the actuator allows the camshaft of the engine to engage and move the associated injector rocker arm to actuate the associated fuel injector, and an operative position wherein the actuator disengages the associated injector rocker arm from the camshaft to prevent the associated rocker arm from actuating the associated fuel injector. A skipfire controller is operatively connected to the skipfire mechanisms and is responsive to an engine operating parameter to actuate selected ones of the skipfire mechanisms to move the actuators thereof to operative positions to prevent actuation of the fuel injectors associated with the selected ones of the skipfire mechanisms.
