    Abstract: An engine catalytic converter misfire protection method and apparatus which controls engine parameters in response to the detection of potentially damaging cylinder misfire. A misfire counter responsive to engine cylinder misfires, counts misfires over a predetermined time period, with the positive changes in the counter output integrated and then compared with a threshold count to determine if the count corresponds to a damaging misfire condition. The apparatus and method simultaneously samples a short term fuel correction signal and compares the short term fuel correction signal with a second threshold. When both thresholds are exceeded substantially at the same time, the apparatus and method shut off fuel to the misfiring cylinder and shuts off the short and long term fuel control. Verification that the proper cylinder has the fuel shut off is made by repeating the control sequence to determine if the fuel has been shut off to the same cylinders.

    Abstract: A fuel injector comprises a body having a longitudinal axis, a length-changing actuator that has first and second ends, a closure member coupled to the first end of the length-changing actuator, and a compensator assembly coupled the second end of the actuator. The length-changing actuator includes first and second ends. The closure member is movable between a first configuration permitting fuel injection and a second configuration preventing fuel injection. And the compensator assembly axially positions the actuator with respect to the body in response to temperature variation. The compensator assembly utilizes a configuration of at least one spring disposed between two pistons so as to reduce the use of elastomer seals to thereby reduce a slip stick effect. Also, a method of compensating for thermal expansion or contraction of the fuel injector comprises providing fuel from a fuel supply to the fuel injector; and adjusting the actuator with respect to the body in response to temperature variation.

    Abstract: A method and apparatus for defining a spray pattern to reduce the variation in the metering, targeting, distribution, and atomization of the fuel output of a fuel injector. The fuel injector contains a closure member extending along the longitudinal axis of the injector. The closure member can be positioned contiguous to a seat to occlude fuel flow. A sealing radius is defined when the closure member is in this position. The closure member can also be positioned such that it is not contiguous to the seat, thereby permitting fuel flow. A plate is disposed proximate to the seat with a first and second face, the first face facing the seat. An inlet is located on the first face of the plate, and at least one chamber is disposed on the second face of the plate. The inlet and the at least one chamber are in fluid communication. An orifice disc is disposed in a confronting arrangement with the second face of the plate such that each chamber is located proximal to each orifice. The orifice disc is positioned such that its axis is generally coincident with the longitudinal axis of the fuel injector. At least one orifice is located at a second radius from the axis of the orifice disc, wherein the second radius is greater than the sealing radius.

    Abstract: A controller for an internal combustion engine detects a demand variable showing a demand from a driver, and controls an intake air volume to the internal combustion engine according to the detected demand variable. When trouble is detected in a system controlling the intake air volume, the controller switches a driving control of a vehicle to a emergency driving mode. In the emergency driving mode, the controller keeps the intake air volume to the internal combustion engine constant. The controller calculates a emergency driving control variable according to the detected demand variable, and controls the driving of the vehicle according to the calculated emergency driving control variable. The emergency driving control variable is a control variable different from the intake air volume. Thus, in the emergency driving mode, the driving of the vehicle can be controlled by the control variable different from the intake air volume, and a better drivability is ensured.

    Abstract: A throttle control for an internal combustion engine comprising an electric motor and a motor drive connecting the motor to a throttle plate of a throttle body, whereby throttle plate control is established solely by the electric motor without a mechanical motion-transmitting mechanism between the vehicle accelerator pedal and the throttle plate. The motor is under the control of an electronic microprocessor that responds to a signal indicating that the engine ignition system has been deactivated. A command is sent by the microprocessor at the time of engine shutdown to the motor to actuate the throttle plate to an intermediate position, thereby avoiding throttle plate freezing and avoiding throttle plate sticking at closed throttle due to deposits, such as hydrocarbon deposits, on the wall of the throttle body.

    Abstract: A powertrain control method for an internal combustion engine having a throttle responsive to a throttle position command. The method comprises the steps of determining the engine speed, determining the actual throttle position, and generating a desired throttle position value. In one aspect of the invention, the desired throttle position value is generated as a function of the actual throttle position and engine speed. In particular, the throttle position divided by the engine speed can be resolved to a single constant. As such, a simplified powertrain control monitor can be obtained by comparing the throttle position divided by engine speed to a predetermined constant. If the throttle position is greater than the desired throttle position value, the commanded throttle position is limited to the desired value.
