  • Patent number: 6911830
    Abstract: A method by which contaminant (soot) content in Diesel engine oil is determined using electrical conductivity measurements of the Diesel oil at a high frequency, or by which contaminant (soot and/or water and/or anitfreeze) content is determined using the ratio of electrical conductivity measurements of the Diesel oil at a high frequency to the electrical conductivity measurements of the Diesel oil at a low frequency. Both the conductivity ratio and the high frequency conductivity are essentially independent of the brand of oil. High frequency is defined to be above 2 MHz whereas low frequency is defined to be D.C. to about 1 kHz.

  • Patent number: 6904937
    Abstract: A switchable fluid control valve assembly having a regulating spool and a pilot spool disposed within a common bore. A regulating spring urges the regulating spool toward a rest position wherein an oil supply port is fully uncovered. Supply oil entering the assembly causes the regulating spool to assume a position wherein oil flow is throttled to a downstream pressure insufficient to activate an associated valve deactivation mechanism but sufficient to provide lubrication to the engine. When activation of the mechanism is desired, a solenoid moves the pilot spool wherein oil at full pressure is engaged against the regulating spool, de-throttling the flow of oil to the mechanism. When the solenoid is again deactivated, a dump port is opened into the oil flow path, immediately reducing the pressure on the regulating spool which then moves to eclipse the supply port and open a path from the mechanism to drain.

The tubes extend in parallel relationship between the headers for establishing fluid communication between the first header and the second header. The second header includes a header portion and a receiver portion. A conduit extends into and out of and is surrounded by the receiver portion to define a space between the conduit and the receiver portion. Heat is transferred between hot refrigerant flowing in the receiver portion, the header portion, and cooler refrigerant flowing through the conduit as the refrigerant flows through the conduit independently of the refrigerant flowing in the space and in the header portion to increase an overall efficiency of the air conditioning system.

  • Patent number: 6904752
    Abstract: The invention provides a controller and cylinder deactivation system to regenerate an exhaust aftertreatment device for a multicylinder engine that operates primarily at an air/fuel ratio that is lean of stoichiometry. The invention uses the cylinder deactivation system to control temperature and air/fuel ratio of an exhaust gas feedstream going into an aftertreatment device. The invention also increases the amount of fuel delivered to each non-deactivated cylinder by an amount sufficient to maintain operating power of the engine. The regeneration action includes desorbing NOx from a NOx adsorber catalyst, desulfating the NOx adsorber catalyst, and purging a diesel particulate trap.

  • Patent number: 6906399
    Abstract: An integrated circuit (10) includes a thermal sensing device (20) and a power-switching device (12) such as an IGBT. The power device (12) is fabricated in a conventional manner on a semiconductor substrate, and the thermal sensing device (20) is fabricated on an electrical insulation layer (74) formed over the substrate. The thermal sensing device (20) may be provided in the form of a number of series-connected polysilicon diodes (D1-D3) positioned adjacent to the power device (12) such that the operating temperature of the thermal sensing device (20) is near that of the power device (12). In response to an input current IC, the thermal sensing device (20) produces an output voltage (VD) that is substantially linear with surface die temperature, and which reacts rapidly to changes in surface die temperature. The thermal sensing device (20) is completely electrically isolated from the power device, thereby eliminating any electrical interaction therebetween.

  • Patent number: 6901914
    Abstract: A fluid pulse damper having increased dynamic range and sensitivity, being especially useful in suppressing pulsations in the fuel supply rail of an internal combustion engine. The damper is a longitudinal gas-filled plastic pillow having walls formed by opposed flexible short sides and opposed flexible long sides, and includes at least one internal self-contact element, and preferably a plurality of such elements. As the short sides flex, the elements make contact internally, shifting the damper into a different compression regime and extending the pressure/response over an increased range of pressures. A feature of some embodiments is that the inner surface within the contact elements is shifted into tension after the elements make contact, thereby stiffening the damper and increasing the damper's resistance to further deformation. The damper is formed of a plastic such as ultra-high molecular weight polyethylenes, high flow polyetherimides, or tubing grade polyphthalamides.
