摘要： The present invention provides a spark plug coil and pressure sensor assembly for providing a spark to a cylinder of an internal combustion engine. The assembly comprises a spark plug configured for mounting in a cylinder and a pressure sensor associated with the spark plug configured to detect a pressure in the cylinder and generate a pressure signal in response thereto. The assembly includes a first electrically conductive ring connector configured to receive the pressure signal and a housing having a main axis and having at least one electrically conductive leaf spring member. The leaf spring member is configured to resiliently engage the first electrically conductive ring connector over a first predetermined circumferential angle relative to the main axis of the coil housing.

摘要： A biasing circuit for an ion current measurement system draws power from a primary side of the ignition coil, and applies a positive polarity bias voltage to a low voltage side of a secondary winding of the ignition coil. The biasing circuit includes a silicon-controlled rectifier (SCR) which has an on state for carrying spark current during a spark interval of operation, and further includes an off state which prevents the stored biasing voltage on a capacitor from being shunted to ground, thereby allowing ion current sensing through the low voltage side of the secondary winding. The low on-state voltage drop of the SCR during conduction of spark current minimizes losses of spark energy.

The coil winding assembly includes a plastic coil spool that carries a pull-in coil and a hold-in coil. One end of the coil spool supports a plurality of axially extending metallic threaded studs that are insert molded into the end of the coil spool. The end leads of the coils are wrapped around the studs and welded thereto. The studs, together with nuts that are threaded onto the threaded portions of studs, serve to secure a plastic cover to an end of the metal case.

摘要： An ignition coil cassette having bushings retained by an irregularity of the bushings being encased by epoxy. As a result, the process by which the bushings are installed into the ignition coil cassette avoids the cost associated with the overmolding installation process, and further avoids the potential for damage associated with the ultrasonic insertion process. The irregularity is located generally adjacent one end of each of the bushings and may be, for example, in the form of an undercut or a protrusion.

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： Staggered firing of first and second spark plugs in a dual-plug spark ignition engine is achieved by apparatus that fires the first spark plug based on an output signal produced by an engine control module and firing the second plug based on the output of a delay control circuit responsive to the output signal produced by the engine control module. The delay control circuit additionally detects engine speed based on the firing frequency of the first spark plug, and selects a delay time so that the firing of the second spark plug is delayed with respect to the firing of the first spark plug by a calibrated angle of engine rotation.

摘要： An impulse noise suppression circuit for an integrator-based ion current signal processing system includes a one-shot circuit activated by a trigger signal that is produced when a noise transient in a bandpass filtered ion current signal exceeds a predetermined threshold. The output pulse of the one-shot circuit is selected to have a pulse width configured to mask a substantial portion of the noise transient without masking the remaining filtered ion current signal during the remainder of a knock window in which knock is detected.

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.
