摘要： An ignition device for an internal combustion engine (1) includes a superpose voltage generation circuit (47) that, after the initiation of a discharge with the application of a discharge voltage by a secondary coil, applies a superpose voltage between electrodes of an ignition plug (29) in the same direction as the discharge voltage to continue a discharge current, and performs a superposed discharge in a superposed discharge activation range of high exhaust recirculation rate. Upon shift from the superposed discharge activation range of high exhaust recirculation rate to a superposed discharge deactivation range of low exhaust recirculation rate, the deactivation of the superposed discharge is delayed by a delay time ΔT. Although the exhaust gas recirculation rate becomes temporarily increased with decrease in intake air after the closing of an exhaust gas recirculation control valve, the superposed discharge is continued for the delay time ΔT so as to avoid misfiring.

摘要： An ignition unit (11) has a superimposed voltage generation circuit (17) that feeds, between electrodes of an ignition plug (9), a superimposed voltage of the same direction as a discharge voltage, and in an operation range wherein an engine rotation speed is equal to or lower than a given speed and an engine load is equal to or lower than a given load, feeding of the superimposed voltage is carried out. Although the energization time for a primary coil (15a) is basically set in accordance with the engine rotation speed, the energization time TDWLON for the superimposed voltage feeding is set shorter than the energization time TDWLOFF for the superimposed voltage non-feeding. With this, temperature increase of the ignition unit (11) caused by the feeding of the superimposed voltage is suppressed.

摘要： A control apparatus for an internal combustion engine according to the present invention includes a spark plug (30) for igniting an air-fuel mixture in a cylinder, and is configured to be capable of measuring a discharge voltage of the spark plug (30). The control apparatus calculates a turbulence intensity index value that indicates the turbulence intensity of in-cylinder gas based on a predetermined frequency component extracted from a discharge voltage during at least a part of a discharge duration leading up to ignition and, in accordance with the turbulence intensity index value, adjusts the ignition energy that is supplied to the spark plug (30) during a combustion duration in a cycle in which the turbulence intensity index value is calculated.

摘要： An ignition circuit and a method of operating an igniter (preferably a travelling spark igniter) in an internal combustion engine, including a high pressure engine. A high voltage is applied to electrodes of the igniter, sufficient to cause breakdown to occur between the electrodes, resulting in a high current electrical discharge in the igniter, over a surface of an isolator between the electrodes, and formation of a plasma kernel in a fuel-air mixture adjacent said surface. Following breakdown, a sequence of one or more lower voltage and lower current pulses is applied to said electrodes, with a low "simmer" current being sustained through the plasma between pulses, preventing total plasma recombination and allowing the plasma kernel to move toward a free end of the electrodes with each pulse.

摘要： An embodiment of a plasma ignition system for an internal combustion engine having up to N cylinders includes a power splitter, N phase shifters, N amplifiers, a power combiner network, and up to N radiation devices. The power splitter divides an input RF signal into N divided RF signals. Each phase shifter applies one of multiple pre-determined phase shifts to one of the N divided RF signals to produce N phase shifted RF signals. The N amplifiers amplify the N phase shifted RF signals to produce N amplified, phase shifted RF signals. The power combiner network combines the N amplified, phase shifted RF signals to produce N output RF signals. Each of the radiation devices receives one of the N output RF signals, and produces a plasma discharge when a power level of the output RF signal is sufficiently high.
