Abstract: A camshaft phaser includes an input member and an output member. A valve spool is moveable along an axis between an advance position and a retard position and includes a valve spool bore. A check valve within the valve spool bore includes a check valve member which moves between a seated position and an unseated position such that the check valve member prevents fluid flow out of the valve spool bore through a passage and such that the check valve member permits flow into the valve spool bore through the passage. An insert within the valve spool bore supports the check valve closes one end of the valve spool bore and abuts an insert retainer to retain the insert within the valve spool bore. A spring urges the insert toward the insert retainer and holds the insert retainer in compression against the insert retainer.

Abstract: A method of testing a fuel injection system or components thereof includes running a high pressure fuel pump to provide fluid under pressure to the fuel injection system or components. The pump flow is controlled via an inlet metering valve by controlling current or voltage supplied to the inlet metering valve dependent on the power to the fuel pump.

Abstract: An apparatus is configured to determine the leakage resistance in respect of the positive and/or negative terminals of a vehicle battery. The apparatus includes a first pair of serially arranged resistors connected between the terminals with a first switch connected between the resistors and a second pair of serially arranged resistors connected between the vehicle chassis/nominal ground and the negative terminal or the positive terminal, with a second switch connected between the resistors. A further fifth resistor is connected between the vehicle chassis/nominal ground, and the negative terminal or the positive terminal via a third switch, and a controller is configured to selectively control the switches during processing steps.

Abstract: A particulate matter sensor includes a shield through which exhaust gases flow in a direction of flow from upstream to downstream. A sensing element with a positive electrode and a negative electrode separated from the positive electrode by an electrode gap is located within the shield. The positive electrode includes a plurality of positive electrode branches each having positive electrode extensions extending downstream and separated from each other by positive electrode slots. A positive electrode extension tip for each has a positive electrode extension tip width. The negative electrode includes negative electrode branches each having negative electrode extensions extending upstream which are each flanked on each side thereof by a plurality of negative electrode slots. A negative electrode extension tip for each has a negative electrode extension tip width. A sum of the positive electrode extension tip widths is greater than a sum of the negative electrode extension tip widths.

Abstract: A fuel system includes a fuel injector having an inlet conduit extending along an axis, a nozzle opening, and a valve needle which is moveable to selectively permit and prevent flow of fuel from the inlet conduit through the nozzle opening. The inlet conduit has a seal support flange which provides a seal support shoulder which is traverse to the axis. A fuel rail assembly includes a fuel rail having a main fuel passage which receives fuel from a fuel source and a socket having a socket bore extending thereinto from a socket open end such that the socket bore is in fluid communication with the main fuel passage and such that the inlet conduit is received within the socket. A sealing ring which is metallic circumferentially surrounds the inlet conduit within the socket bore such that the sealing ring is compressed between the socket bore and the inlet conduit.

Abstract: A method of determining the electrical resistance of an actual harness connecting the Engine Control Unit (ECU) to a solenoid valve. The method includes providing a dummy harness connected at one end to the ECU and at the other end to a terminal connection in the vicinity of the solenoid valve. The method also includes determining the estimated RMS current through the actual harness and passing a current through the dummy harness such that the heat exchange to the environment is substantially the same as the actual harness. Power consumption of the dummy harness is measured and resistance of the actual harness is determined from estimated RMS and power consumption of the dummy harness.

Abstract: An oxygen sensor is in a system including compensator circuitry connected to the oxygen sensor. The oxygen sensor includes a pump cell and the compensator circuitry includes a feedback control loop which includes a digital compensator which determines and outputs a compensation current to the pump cell or adjusts a pump cell voltage. A method of controlling the oxygen sensor includes, subsequent to a period of time when the feedback control loop is disrupted, pumping a balancing current into or out the pump cell for a balancing time interval, the balancing current and/or the balancing time interval is dependent on a current pumped into or out of the pump cell prior to the feedback control loop being disrupted.
