摘要： A plasma ignitor, or plasma source, for igniting a combustible mixture in an internal combustion engine. The ignitor includes at least two spaced apart electrodes dimensioned and arranged such that an outwardly moving plasma is formed when a voltage is applied across the electrodes. The present invention is characterized by its efficient use of input electrical energy for driving the plasma ignitor and by an ignition plasma kernel which is several orders of magnitude larger than that produced by conventional spark plugs. Outward motion and expansion of the plasma kernel is produced by a combination of Lorentz and thermal forces. Use of very lean combustible mixtures, in which the dilution of the mixture is achieved by use of exhaust gas recirculation, is made possible by the present ignition system. Improvement in engine efficiency, and a major reduction in exhaust gas pollutants are obtained.

摘要： An ignition device sets a total discharge period, each discharge period and each intermittent period of a multiple discharge are set by a control map in addition to the setting of a throttle opening, fuel injection timing, fuel injection period and ignition timing for the range of non-stratified charge combustion, when a direct injection-type engine operates in the range of stratified charge combustion. Ignition signals including a plurality of rises and falls are outputted in time with a specific ignition timing after fuel injection. Thus a plurality of sparks are generated from the spark plug, ensuring reliable ignition in response to changes in the concentration of sprayed fuel within the operation range for stratified charge combustion.

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.
