Abstract: A fuel injection pump is proposed in which the fuel metering takes place during the intake stroke of the pump pistons via a fuel supply line in which a switching valve is mounted, which is opened upon the onset of the intake stroke of the pump pistons, closes in the course of this intake stroke and with this closing point also determines the injection onset upon the ensuing supply stroke of the pump pistons. The quantity of fuel to be injected is then limited by means of a pump-guided control edge, which is disposed on an annular slide provided on a free end of the distributor of the fuel injection pump; when a first control opening on the distributor which communicates with the pump work chamber coincides with a second control opening on the annular slide, the pump work chamber is relieved. The diversion or gradual shutoff point is controlled in the course of the compression stroke movement of the pump pistons by means of the relative rotation of the working point of the second control opening.

Abstract: An automatic shut off device for preventing air from entering the fuel system of an internal combustion engine when the fuel supply becomes low. The device provides a fuel chamber having an inlet connected to a fuel supply line, a float switch and an outlet connected to the engine fuel pump or fuel system. When the fuel supply falls below a preselected low level, but before the level reaches a lower inlet to a standpipe, the float switch is actuated to shut down the engine before air can enter the engine fuel system, thereby eliminating the necessity of bleeding the fuel system when the fuel supply is restored. A bleed orifice at the top of the fuel chamber allows trapped air to escape and return to the fuel tank when fuel is restored to the device.

Abstract: A fuel injection nozzle of this invention includes a nozzle housing which defines therein a fuel sump chamber, stepped cylinder bore and fuel passage connected at one end to the sump chamber and at the other end to a smaller diameter bore section of a stepped bore. A stepped plunger is fitted into the stepped cylinder bore to define a pump chamber communicating with the fuel passage and a main fuel chamber into which the main fuel is supplied from a fuel injection pump. An auxiliary fuel is supplied from a feed pump through the fuel passage into the sump chamber and pump chamber. A nozzle needle is located within the nozzle housing and is responsive to a fuel pressure within the sump chamber to cause it to be lifted to permit an injection hole to be opened. The nozzle needle is urged under a predetermined force of a pressure spring in a direction in which the injection hole is blocked.

Abstract: A device for the recovery of fuel vapors originating in the fuel system of a vehicle, particularly at the gas tank thereof or in the carburetor float bowl. In one arrangement, a fuel vapor line connects the fuel tank to an input port of a fuel vapor storage and recovery canister containing activated carbon or charcoal, with another port thereof, referred to as a "purge" port, being connected with either the engine intake manifold or else a vacuum port of the carburetor. Carried by the canister is a self-regulating electric heater assemblage adapted to heat air flowing into the canister through a large air port, thereby to also heat the charcoal. When the vehicle is idle, fumes from the gasoline tank can enter the input port of the canister to be adsorbed and stored by the charcoal. When the vehicle is operated, vacuum from the intake manifold draws air into the canister, causing the heated charcoal to release its stored fuel which is then burned in the engine.

Abstract: The timing of the injection of fuel to the cylinders of a diesel engine is normally determined in accordance timing values obtained from an empirically derived steady state timing schedule but is modified during transient engine operation by an amount determined in accordance with the cylinder-to-cylinder change in requested fuel amount. In light to moderate engine acceleration, the steady state timing value is modified by a correction amount which serves to retard the start of injection for effecting a reduction in engine noise and exhaust emissions. In periods of heavy engine acceleration, the steady state timing value is modified by a correction amount which serves to advance the start of injection to improve the engine performance. When the cylinder-to-cylinder change in requested fuel quantity indicates a return to substantially steady state engine operation, the correction amount is reduced in relation to the correction amount magnitude and the cylinder firing frequency.

Abstract: A mechanism for pumping fluid in response to pressure pulses, the mechanism comprising a fluid pump including a reciprocating piston operable to pump fluid, a rotatable eccentric wheel including a cam surface, a linkage engageable with the cam surface for rotating the wheel in response to pressure pulses, and a linkage engageable with the cam surface for causing reciprocation of the piston in response to rotation of the wheel.

Abstract: A trouble light is provided and consists of a reflector adjustably supported around an electric light socket for an electric light bulb with a guard to provide illumination, a device for turning the reflector around the socket in 360.degree. to direct the illumination from the bulb in any direction therefrom and a friction spring for holding the reflector in position after the reflector is turned. The guard is multi-sided so that it does not roll when laid down to rest.

Abstract: A motorcycle having a V4 crankcase compression, two-cycle internal combustion engine having an improved, compact induction system. The induction system for the cylinders of one bank discharges directly into the crankcases of those cylinders and is fed with a pair of carburetors through an induction system which induction system is positioned at least in part in the area between the banks of cylinders. The carburetors are disposed at least in part at the sides of the engine. The cylinders of the other bank are supplied with a charge indirectly to their crankcases through a similarly configured induction system. The induction system of one bank has its charge forming devices positioned above the charge forming devices of the other bank.
