<P>PROBLEM TO BE SOLVED: To shorten the length of a wave guide by disposing the magnetron adjacent to the internal combustion engine and to restrain breakage of a cathode part of the magnetron by mechanical vibration in an igniter comprising a spark-ignition internal combustion engine for igniting a fuel/air mixture by generating plasma in a combustion chamber and reacting the plasma with spark discharge by an ignition plug and a magnetron used in combination for generating a microwave for generating the plasma. <P>SOLUTION: The igniter used in combination with a spark-ignition internal combustion engine for igniting a fuel/air mixture by reacting spark discharge by an ignition plug and plasma produced in a combustion chamber is used in combination with a magnetron comprising a cathode part for discharging electrons and an anode part for accelerating the discharged electrons with respect to the cathode part, and a magnet part for forming a magnetic field in the interaction space of the cathode part and the anode part for producing plasma in the combustion chamber. The axial direction of the cathode part of the magnetron is disposed coinciding with the principal vibration direction of the spark-ignition internal combustion engine. <P>COPYRIGHT: (C)2010,JPO&INPIT |
