摘要： A vehicle engine throttle valve control device (10;121) is applied intermediate the vehicle operator's accelerator pedal (14) and the engine's throttle body (12) to selectively override or modify the operator's ability to control vehicle/engine speed and to assert independent control thereof as a function of various input parameters (49,50,52,54). Linkages (26,28) interconnect opposed ends of a lever (18;136) respectively, with accelerator and throttle. The lever rotates upon a pivot (20;126) which is selectively displaceable to effectively shorten or lengthen the linkage in response to an operator independent signal from a control circuit (42).

摘要： A servo motor operated rotary air throttle has a driving member connected to the throttle shaft. The motor rotor is connected to the driving member in a lost motion connection. If the throttle is lodged due to ice formation, the motor rotor acquires rotary momentum relative to the driving member during the lost motion rotation and a projection on the rotor impacts the end of a slot in the driving member to impart a momentum pulse to the driving member and throttle shaft and dislodge the throttle.

摘要： A vehicle engine throttle valve control device (10) is applied intermediate the vehicle operator's accelerator pedal (14) and the engine's throttle body (12) to selectively override or modify the operator's ability to control vehicle/engine speed and to assert independent control thereof as a function of various input parameters (49,50,52,54). Linkages (26,28) interconnect opposed ends of an assembly of half levers (21,23) with accelerator and throttle. The half levers rotate upon a pivot (20) which is selectively displacable to effectively shorten or lengthen the linkage in response to an operator independent signal from a control circuit (42). A half lever stop (27) fixes the relative positions of the half levers whenever the throttle body is in an off-idle position.

摘要： A variable valve actuation assembly (41) to be mounted about a camshaft (43) including a concentric portion (47) and an eccentric portion (49) which orbits the axis of rotation (A1) of the camshaft and defines an axis (A2). The assembly (41) includes a secondary cam member (51) surrounding the concentric portion (47) and including a cam surface (59,59L). The assembly (41) also includes an arm assembly (61) which surrounds the eccentric portion (49), and defines a longitudinal axis (A3) perpendicular to, and intersecting the axis (A2). The arm assembly (61) can pivot about a pin (71), and at the opposite axial end is pivotally connected to the secondary cam member (51) by means of a pin (75). Rotation of the camshaft (43) causes the arm assembly (61) to pivot about the pin (71) in one direction, rotating the cam member (51) to lift the valve (17), then pivot in the other direction, rotating the cam member (51) in the opposite direction.

摘要： A transducer housing for mounting a port in a combustion chamber has a metal diaphragm exposed to the combustion gasses. The pressure of the combustion gasses deflects the diaphragm which locally deflects a simply supported beam. The beam is formed of refractory material having epitaxially grown crystalline piezoresistors formed on one surface of the beam and connected in a bridge circuit. Noble metal foil leads connect to the piezoresistors to form the bridge and provide attachment pads. The pads are noble metal welded to other noble metal foil pads provided on a ceramic substrate to form a sensor subassembly for mounting adjacent the diaphragm to form a transducer.

摘要： A torch ignitor for a lean burn internal combustion engine is disclosed in which a small quantity of gaseous fuel is activated by exposure to an electrical arc and injected into the main fuel air charge in the combustion chamber. The arc is established by causing a current to flow to a pair of electrodes which are separated by the application of the torch fuel under pressure to generate the arc. The arc is caused to migrate about the space between the electrodes by the impingement of the fuel flowing through the space.

摘要： A servoactuator for a vehicle throttle having a direct current motor driving a speed reducer with the output thereof connected to slidably move a fulcrum member having a lever arm pivoted thereon. The lever arm has a cable to the engine throttle connected to one end and a cable to the vehicle accelerator pedal connected to the other end on the opposite side of the pivot. In one embodiment the speed reducer drives an axial lead screw threaded in the fulcrum member. In a second embodiment the speed reducer output is a slotted crank arm having a pin on the fulcrum member slidably received therein. In a third embodiment the speed reducer output is connected by a two-bar linkage to the fulcrum member. A potentiometer is disposed to have the movable element thereof moved by one end of the lever to provide a throttle position feedback signal for use by an external motor control signal generator. The servoactuator is intended for use with a vehicle traction control system.

摘要： Fuel is activated prior to combustion in an engine by an electrical arc established across an annular gap between two electrodes, and sustained for a significant portion of the injection cycle. The vaporized or gaseous fuel is directed through a spiral recess to be caused to flow vortically and cause the arc to migrate about the annular gap to reduce electrode erosion and increase exposure of the fuel to the activating effects of the arc. The arc is formed by separating contacting electrodes which applying a current to the electrodes. One of the electrodes is movable under the influence of the pressurized fuel to cause separation from the other fixed electrode, so that the arc is established as fuel begins flowing. The electrodes have opposing rimmed cavities, with fuel flow shifting the arc radially inwardly, migrating to extend between the inner wall of each cavities, and around which the arc rotates under the influence of the vortical fuel flow.

摘要： A misfire detection system and method for use in conjunction with an internal combustion engine. An engine cylinder has a pressure sensor disposed therein for providing a signal indicative of the pressure in the cylinder's combustion chamber. Compression pressure measurements are obtained at crankshaft angles reached prior to the top dead center position of piston travel. For crankshaft angles greater than that at which top dead center is reached, the pressure measurements are reflected about a vertical axis extending through the top dead center point. The reflected compression pressures for crankshaft angles reached after the top dead center point are subtracted from the actual compression chamber measurements obtained over those crankshaft angles during the power stroke of the engine. The difference values are integrated over a range of crankshaft angles to produce a difference pressure integral which is normalized through multiplication by an optional factor and then subsequent division by the maximum pressure occurring in the compression chamber during the engine's power stroke. The resulting normalized integral value is compared to a threshold, below which partial or complete engine misfire is presumed.
摘要翻译： 与内燃机结合使用的失火检测系统和方法。 发动机气缸具有设置在其中的压力传感器，用于提供指示气缸燃烧室中的压力的信号。 在活塞行程的上止点位置之前达到的曲轴角度获得压缩压力测量值。 对于大于达到上死点的曲轴角度，压力测量反映在延伸穿过上止点的垂直轴线上。 在发动机功率冲程之前，从在上止点之后达到的曲轴角度的反射压缩压力从在这些曲轴角度获得的实际压缩室测量值中减去。 差值被集成在曲轴角度的范围上，以产生差压积分，该差压积分通过乘以可选因子然后在发动机的动力冲程期间随压力室中发生的最大压力而被归一化。 将所得到的归一化积分值与阈值进行比较，低于该阈值时，推定部分或完全发动机失火。
