摘要： The probe includes a tubular housing having a first portion and a second portion. The first portion is adapted to be mounted in place of the glow plug of a selected engine cylinder. A light pipe within the first portion directs light from the combustion zone to a phototransistor within the second portion. The front of the first portion has a reduced size aperture defined by an internal shoulder against which the front of the light pipe is seated. The rear of the first portion carries resilient sealing means which is deformed when the second portion is telescoped thereon so as to provide a detachable, frictional, light-tight thermally insulated connection therebetween. A phototransistor is mounted within the second portion to convert light passing through the light pipe into electrical signals. A cable carries these electrical signals to processing equipment. A base resistor is located in the second portion between the base of the phototransistor and the cable. The part of the first portion that projects from the engine is short with respect to the part that fits into the engine. The projecting portion carries wrench-engaging bosses.

摘要： The apparatus comprises a luminosity probe to provide an electrical signal in response to the combustion event in a diesel engine and also comprises a probe to provide another electrical signal indicative of top dead center. Both electrical signals are processed and applied to a circuit which generates an output pulse having a duration corresponding to the time between the start of the electrical signals. A meter displays the angle represented by the duration of such pulse. Circuitry is provided to compensate for offset.

摘要： A first signal at a first frequency which is a selected harmonic of the resonant frequency of a bolt in a first loaded condition is determined. Then there is determined a second signal at a second frequency being the same harmonic of the resonant frequency of the bolt in a second loaded condition. Both frequencies are multiplied by a factor M. The up input of a counter receives one of the signals for a predetermined duration, and the down input receives the other signal for the same duration. The number of pulses remaining in the counter is representative of the difference in load between the first and second loaded conditions.

摘要： The adapter includes a luminosity probe for replacing the glow plug associated with the selected cylinder in a diesel engine, a timer circuit responsive to inception of each electrical signal generated by the luminosity probe to produce a timer signal. The timer signal is differentiated to produce a spike. A pickup loop receives the spike and produces an inductive signal for application to the clip of a spark-ignited-engine timing meter.

摘要： The adapter includes a housing containing a rectifier for supplying flash voltages to an LED. The rectifier rectifies inductive signals derived from an inductive pickup. The adapter can be used to enable a spark-ignited engine calibrator to calibrate a diesel-engine-timing meter by converting the inductive electrical signals from the calibrator to light signals for the diesel timing meter. The adapter also can be used to enable a diesel-engine-timing meter and analyze and time a spark-ignited engine by converting the inductive pulses derived from a spark plug wire into light impulses for the diesel-engine-timing meter.

摘要： A self-adjusting engine timing pickup probe adapted to be received in a tubular engine mounting bracket, the probe extending into close proximity with a position indicator on a rotating engine part to provide an air gap. An elongated sensor assembly extends through the tubular member and has relative axial movement therewith for initial manual adjustment of the sensor assembly to provide an effective air gap. Interference means are provided between the tubular member and the sensor assembly, the interference means establishing substantial resistance to relative axial movement between the tubular member and the sensor assembly. The tubular member has a spring means which engages the engine mounting bracket and holds the two together in a yielding manner. The spring means urges the tubular member and associated sensor assembly inwardly toward the rotating engine part. However, during engine operation, the rotating engine part, due to tolerances, wear, vibrations, etc., engages the sensor assembly and tends to move both the sensor assembly and the tubular member outwardly of the mounting bracket. In so doing, the spring means holding the tubular member in the engine mounting bracket yields, while the interference means between the tubular member and the sensor assembly does not yield. Thus, the engagement between the sensor assembly and the rotating engine part does not cause relative axial movement between the tubular member and the sensor assembly.
摘要翻译： 一种自适应引擎定时拾取探头，其适于容纳在管状发动机安装支架中，探头与旋转的发动机部件上的位置指示器紧密接近以提供气隙。 细长的传感器组件延伸穿过管状构件并且具有相对的轴向运动，用于传感器组件的初始手动调节以提供有效的气隙。 干涉装置设置在管状构件和传感器组件之间，干涉装置建立了对管状构件和传感器组件之间的相对轴向运动的实质阻力。 管状构件具有弹簧装置，该弹簧装置接合发动机安装支架并以屈服的方式将两者保持在一起。 弹簧装置将管状构件和相关联的传感器组件向内推向旋转的发动机部件。 然而，在发动机操作期间，旋转的发动机部分由于公差，磨损，振动等而接合传感器组件，并且倾向于将传感器组件和管状构件两者移动到安装支架的外部。 在这样做时，将管状部件保持在发动机安装支架中的弹簧装置产生，同时管状部件和传感器组件之间的干涉装置不产生。 因此，传感器组件和旋转的发动机部件之间的接合不会导致管状部件和传感器组件之间的相对轴向运动。

摘要： The tool is a pliers or cutters having two members that are pivotally joined. The portions of the members on one side of the joint define cutter jaws or plier jaws as the case may be. On the other side of the joint, the members define handles located on the same side of the jaw axis. The rear handle has a first section nearest its associated jaw extending away from the jaw axis at an acute angle, and a second section extending from the first section at an obtuse angle. The other handle also has two sections, the first section nearest the jaws having a slight curvature and the second section having a curvature which is convex outwardly and is more pronounced than that of the first section.

摘要： An engine timing apparatus includes a piezoelectric transducer and a device for mechanically coupling it to a fuel injector body of the engine. A 6-inch clamping-type pliers is clamped to the injector body. A metal housing is fastened to the pliers at the jaw pivot, the housing having a cylindrical side wall and a circular bottom wall in positive contact with the pliers. The transducer is supported in a recess in a rubber sleeve in the housing and cooperates with the housing to define a resonant chamber at substantially 40 Khz. The dimensions of the pliers are such that the ultrasonic acoustic emissions of the injector body induce in the pliers a standing wave at substantially 40 Khz or a harmonic thereof, the jaw pivot being disposed substantially at an antinode, or point of maximum displacement, of the standing wave. The housing above the transducer is filled with an acoustically insulating foam and covered with a plastic cap.
