PURPOSE:To perform perfect combustion of gas even at low temperature, by utilizing pressing force of plurally provided reed springs and pressing out oil dregs from the reed in addition to opening and closing action of the reed itself of a plug while providing a vent hole to a mounting screw. CONSTITUTION:Explosion is operated in a cylinder of an engine, and the next moment a negative pressure is gnerated in the cylinder. Then the outside air flows in through a vent hole 6 into the cylinder, and a pressure of the outside air overcomes tension of a reed spring 8 to open a reed 7, then the outside air flows in through a gap between a plug mounting screw 2 successively formed to an internal wall 4 of a ring groove 3 and a thread of the engine finally flows into the cylinder. Engine oil adheres to the reed 7, and opening and closing action of the reed 7 is immediately worsened by remaining heat of the engine after its stopping, but pressing force of the spring 8 is utilized and oil dregs are pressed out from the reed 7. While the reed spring 8 consists of springs 8a, 8b having different tension. |
