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 an apparatus and method for lubricating a plunger residing within a bushing of a fuel injector. The apparatus includes a fuel lubrication mechanism comprised of lubrication grooves formed within and around the outer axial surfaces of the plunger. The grooves act as fuel reservoirs for storing a small portion of fuel on the outer axial surface of the plunger. The stored or retained fuel interfaces with the walls of the bushing during injection to provide a lubricated interface between the bushing and plunger. The lubricated interface increases the service life of the fuel injector by reducing seizing, scoring and scuffing caused by excessive heat.

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.
