摘要： PROBLEM TO BE SOLVED: To provide an ignition device which appropriately suppresses spark discharge-derived high frequency noise without interposing a resistance for reducing the high frequency noise between a center electrode of an ignition plug and a terminal. SOLUTION: In the ignition device 100, a center coil 3 and the center electrode 12 are connected without a resistance but by use of a conductor 13 and a coil 14 for reducing noise generated in ignition. It is not necessary, therefore, to interpose a resistance for reducing the high frequency noise between the center electrode 12 and the terminal 11. Particularly, when plasma atmosphere is generated in a space between the center electrode 12 and a grounding electrode 17 by high frequency voltage from a high frequency oscillator 5, the ignition device 100 avoids a trouble such that the high frequency voltage is attenuated by the resistance.

摘要： PROBLEM TO BE SOLVED: To provide an internal combustion engine control system which can maintain a discharge condition during a discharge requirement period, while maintaining discharge current at a high level under any conditions.SOLUTION: When primary current decreases at switching timings t2-t3, a DC-DC converter increases the inclination of the primary current at the switching timings t3-t4, thereby controlling the primary current so that it may reach a specified value I1th at a switching timing t4. The value of discharge current I2 is slightly reduced by improving the primary current immediately. As the primary current is improved at the switching timing t4, the current value of the discharge current I2 is also improved at the switching timing t4. For this reason, the degree of the discharge current I2 to drop beyond the specified value I2th of the discharge current is restrained, and the value of the discharge current I2 is maintained at a high level. As a result, the discharge current I2 can keep a stable discharge condition with almost no interrupted discharges.
