MICROWAVE SPARK PLUG FOR MICROWAVE ENERGY INJECTION

Japanese Patent JP2016186306

A

PROBLEM TO BE SOLVED: To provide a method for injecting microwave energy to an existing engine.SOLUTION: A microwave spark plug (1) for injecting microwave energy into a combustion space (18) of an engine comprises an elongated housing (2) including an elongated space (10) forming a hollow conductor inside and a microwave window (8) that is disposed in a first end of the internal space and encapsulates a hollow conductor (10) to a combustion chamber. The hollow conductor (10) includes a connection element (4) for a high frequency supply conductor in a second end that is disposed at an opposite side of the microwave window (8). The connection element has a high frequency inlet cross-sectional shape (7) that is different from a high frequency outlet cross-sectional shape in the microwave window and includes continuous provision of a transition from the high frequency inlet cross-sectional shape in the first end of the hollow conductor to the high frequency outlet cross-sectional shape in the second end of the hollow conductor. The microwave spark plug is screwed into a typical through-hole for spark plug.SELECTED DRAWING: Figure 1
