Abstract: A minimum quantity lubrication (MQL) tool including a lance. The lance includes a passageway and an orifice. The passageway extends axially from a first end of the lance toward a second end of the lance and allows a lubricant supply to flow therein from the first end of the lance toward the second end of the lance. The first orifice extends radially through the lance at a location near the second end of the lance. The lubricant supply flowing through the passageway exits the orifice and is impinged upon by air flowing around the lance.

Abstract: A method for shaping a blind slot in a workpiece includes using a standard computer numerical controlled machine center to radially step a single slot broaching tool into a precursor slot in the workpiece for a predetermined distance to form a slot with a blind end. After the slot with the blind end is formed, the method includes rotating at least one of the workpiece and the single slot broaching tool and radially stepping the single slot broaching tool into another precursor slot for another predetermined distance to form another slot with another blind end in the workpiece. The another predetermined distance is the same as the predetermined distance, or in the alternative, the another predetermined distance is different than the predetermined distance.

Abstract: A fuel pressure sensor 12 which receives air 62 from an intake manifold 58 and fuel 15 from a fuel rail 14 and which uses the received air 62 and fuel 15 to measure the fuel pressure within the fuel rail 14. The fuel pressure sensor 12 further including a semi-permeable membrane or member 60 which allows the air 62 to pass into the fuel pressure sensor 12 while concomitantly preventing the fuel 15 from passing into the intake manifold 58.

Abstract: A fuel tank pressure sensor assembly includes a pressure sensing element portion and a rollover valve portion. An area of reduced section between the sensor element portion and the valve portion provides a controlled fracture location for the pressure sensor assembly. In addition, the valve portion prevents inadvertent closure under normal vehicle operating conditions.

Abstract: An onboard diagnostic mechanism for a sealed vehicle fuel delivery system. By controlling fuel system valves, the electronic engine controller (EEC) periodically subjects the sealed system to an initial vacuum level, then monitors the pressure increase due to evaporative effects during a predetermined test interval. Excessive deviations in measured pressure compared to predetermined criteria produce indications of potential undesired operational conditions. To prevent fuel sloshing which results from aggressive driving or rough roads from producing false output indications, the instantaneous system pressure is compared with a rolling average of tank pressure to produce a difference signal indicative of fuel sloshing. If the resulting difference signal exceeds a predetermined threshold, the monitoring process is aborted in favor of a later test after the fuel sloshing condition terminates.

Abstract: In one embodiment of the present invention, a vapor management system for the fuel system of a motor vehicle includes two carbon canisters for the capturing of fuel vapor from the vehicle's fuel tank. A fuel vapor control valve allows loading of the fuel vapor into the canisters in series and subsequent purging in parallel to the air intake of the vehicle's engine.
