摘要： Engine cylinder contribution analysis is provided. An engine cylinder contribution tester includes a displacement measurement device and a signal analyzer. The displacement measurement device detects engine block movements or displacement relative to a fixed position caused by a poorly contributing cylinder. The displacement measurement device provides a displacement signal to the signal analyzer. The signal analyzer includes a cylinder contribution module for evaluating the displacement signal. If a particular cylinder is contributing less than the average of the other cylinders, the displacement signal indicates engine block movement associated with a lack of contribution from that cylinder.

摘要： A capacitive sensor for a coil-on plug ignition testing apparatus includes a first portion of the capacitive sensor and a second portion of the capacitive sensor, at least one of which has a substantially planar base, and each of which has one or more engagement members projecting downwardly therefrom. One of or both of the first portion and the second portion may be a capacitive element forming a part of the capacitive sensor. The second portion is connected, and is configured to slide relative, to the first portion. A biasing element is disposed between the first and second portions to bias the first portion toward the second portion and to maintain the first portion and second portion in a compressed state. The first portion may be translated relative to the second portion against a bias of the biasing element, to an extended state for securing to a coil-on plug housing. An electrical connector electrically connects the first portion and/or the second portion forming a capacitive element to an output terminal.

摘要： A testing apparatus for testing a waste-power ignition coil is provided and includes an igniter simulator having a first switching device electrically connected to an output of the primary side of a waste-power ignition coil under test and a triggering means for changing a state of the first switching device at a predetermined interval. A second switching device bears a first pair of contacts being electrically connected to one of a positive going and negative going output of a secondary winding of the waste-power ignition coil under test and a second pair of contacts being electrically connected to another of a positive going and negative going output of the secondary winding of the waste-power ignition coil under test. The second switching device acts substantially synchronously with the igniter simulator actuator to ground a respective one of the positive going and negative going output of the secondary winding of the waste-power ignition coil under test to simulate a waste-stroke phase.

摘要： An apparatus for measuring ignition charge signals produced by coils of coil-on-plug devices of an internal combustion engine. A signal detector comprises an insulating substrate having a first conductive planar layer on a first side and a second conductive planar layer on a second side. The first layer is coupled to a signal wire and the second layer is coupled to a ground wire. When the signal detector is held in close proximity to the coil of the coil-on-plug, ignition signals generated by the coil and passing to the plug are detected. The detected signals may be coupled to a signal analyzer for display and analysis. The amplitude of the signal that is output by the signal detector may be adjusted to different coils having different output signal strengths by modifying the ratio of the surface areas of the first layer and the second layer.

摘要： A connector for joining two strings in precise axial alignment including a first enlarged section having a bore with a recess for receiving a knotted connector string, a second reduced-diameter section having alignment surfaces, and a third section having clip ends. Two such connectors are clipped together by inverting one and placing its clip ends over the second section of the other connector. The connectors are preferably of unitary plastic design, such that the clip ends are substantially rigid, with some resilience to allow for clipping. The inner shape of the clip ends corresponds to the outer shape of the second sections, and may be circular, trapezoidal, or some other shape. Clip ends may be provided with elongated ends to assist in removing the connectors from one another. The connector is designed to clip coaxially to another connector, such that the two string lines are coaxial, thus avoiding lateral forces from being exerted by the string lines on the connectors when assembled. A ridge may be provided in the second section to enhance rigidity. The connectors are disassembled by cocking or twisting one connector relative to the other.

摘要： A method for efficiently determining whether a distributorless or hybrid ignition system is the origin of engine problems by consecutively disconnecting and reconnecting the primary connector from each coil of the ignition system. Once a single primary connector is disconnected from a coil and engine misfiring or roughness declines, the problem cylinder pair has been located. The method further includes measuring the firing line voltage of accessible spark plug wires for each cylinder to identify a single faulty cylinder, that may now be serviced.
