    摘要: An ignition coil durability testing apparatus and method utilizing an electronic spark timing circuit, a plurality of SCRs, a plurality of LEDs, and a voltage detection circuit. The electronic spark timing circuit activates an ignition switching transistor which applies a time varying voltage to a primary winding of an ignition coil. The plurality of SCRs are connected in series. A sustaining voltage device in the form of a spark gap or zener box is connected in series with the plurality of SCRs. The secondary winding of the ignition coil is connected to one end of the spark gap or an input of the zener box and to one input of a comparator through a voltage divider and a voltage reference is also connected to the other input of the comparator. When the output voltage of the secondary winding exceeds a preset breakdown voltage, the comparator turns on the plurality of LEDs which activate the plurality of SCRs. The high voltage of the secondary is then applied across the plurality of SCRs and the sustaining voltage device.

    摘要: A thick film resistor strain gauge is applied to a stainless steel shell portion of a spark plug. There are two preferable ways of applying a thick film resistor to the metal shell. In a first embodiment, the thick film resistor may be directly printed on to the shell portion with special screen printing equipment. In a second embodiment, the thick film resistor is printed and applied as a decal to the shell portion. The thick film resistors may be included in a quarter, a half, or a full wheatstone bridge strain gauge circuit. One of two embodiments of an automatic drift compensating circuit is used to determine the change in resistance experienced by the thick film resistors affixed to the spark plug. Either one of the automatic drift compensation circuits output a voltage signal which is proportional to the pressure changes occurring inside the engine cylinder into which the spark plug is threaded.

    摘要: A drive circuit for an ignition system includes an ignition coil and spark plug associated with each cylinder of an internal combustion engine. Each ignition coil has a primary winding with the first end connectable to a power source and a second end opposite the first end connected to a silicon-control rectifier (SCR). Each coil also has a secondary winding connectable to a respective spark plug. The SCR may be integrated with the coil. A main driver device is connected between the other end of the SCR and ground. The driver device is configured to conduct a primary current in response to a drive signal. The SCRs are controlled into conduction by a respective gating signal. A control circuit is configured to generate the gating signals and the drive signal in response to one or more ignition control signals. An SCR for each coil is used to select which coil is allowed to carry current when the main driver is turned on. This allows the use of a single driver device, and multiple SCRs as selectors, thereby reducing the cost of the drive circuit since SCRs are less expensive.

    摘要: An ignition coil, spark plug, and pressure sensor for an internal combustion engine are, in a preferred embodiment, integrated into a single assembly and mounted directly on a plug hole of an internal combustion engine. A hard spark plug shell serves as a pressure member and on which a strain gage is affixed. Changes in the pressure in the combustion chamber deform the shell, causing a corresponding change in the resistance of the strain gage. A bridge circuit or the like is used to measure the resistance change thereby providing a direct indication of cylinder pressure.
