摘要： An ignition coil for an internal combustion engine improves high-voltage sealing performance and moreover reduces housing outer diameter. The ignition coil for an internal combustion engine is made up of a transformer portion of cylindrical configuration housed within a housing chamber of a case, a control-circuit portion, that is positioned on one end portion of this transformer portion, causing primary current of the transformer portion to be intermittent, and a connecting portion that is positioned on another end portion of the transformer portion, supplying secondary voltage of the transformer portion to a spark plug. A silicone rubber injection molding serves as the encapsulant while forming the high voltage boot to the plug.

摘要： A method for inhibiting or eliminating case erosion in a pencil ignition coil having an internal primary winding and an external secondary winding and shield. Three alternative means for resisting damage due to the partial discharge phenomenon arising from a high electric field in such coil configurations are provided: (i) applying an ozone resistant coating on the case; (ii) applying a coating on the case for eliminating partial discharge under the shield; and (iii) applying a polyimide tape covering to the case for resisting partial discharge under the shield. Several significant benefits include: an increased commercial value by allowing the use of an efficient internal primary winding which increases energy density and eliminates the need for a spool, thereby lowering the manufacturing costs, the processing costs falling well beneath that of liquid polymer processing, the ease of processing by coating or molding, the reduction of electrical noise, the improved durability even through thermal cycling, and the lowering of case manufacturing costs by allowing the use of lower cost plastic.

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.

摘要： A system and method of providing multicharge ignition are provided. The method and system preferably are adapted to trigger at least some of the multicharge events of the system and method in a current-dependent manner. Preferably, existing power train control units (PTCUs) can be used with the system and method, without the need for signals other than the timing signal (e.g., EST pulse) from the PTCU. The method comprises the steps of charging an inductive energy storage device by flowing electrical current through a primary side of the inductive energy storage device until a predetermined amount of energy is stored therein, discharging a portion of the predetermined amount of energy through a secondary side of the inductive energy storage device by opening a path of the electrical current through the primary side upon achieving the predetermined amount of energy in the inductive energy storage device, and repetitively closing and reopening the path to recharge and partially discharge, respectively, the inductive energy storage device, wherein reopening of the path is triggered based on the amount of energy stored in the inductive energy storage device. The multicharge ignition system comprises an inductive energy storage device and electronic ignition circuitry. The inductive energy storage device has primary and secondary sides inductively coupled to one another. The electronic ignition circuitry is connected to the primary side and is adapted to implement the aforementioned method.

摘要： An ignition coil, spark plug, and pressure sensor for an internal combustion engine are 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 magnetostrictive section for pressure detection. A radially polarized biasing magnet is disposed adjacent the spark plug shell thereby generating an initial flux through a sensing winding. The sensing winding is wound about the lower end of the coil case to sense changes in the induction characteristics of the spark plug shell as a result of pressure changes in the cylinder. A first passive method of sensing pressure whereby the flux change due to the permeability change generates a signal voltage in the sensed coil. This voltage is proportional to the time rate of change of pressure which is integrated to produce a cylinder pressure waveform. A second active method employs an oscillator to drive the sensing circuit with a frequency at least ten times that of the pressure signal content. The frequency or amplitude of this signal is then modulated in response to the induction property change of the spark plug shell the induction changes The second method is capable of detecting both static and dynamic pressure.
