Abstract

PURPOSE:To control the electric circuit of an ingnition device through detecting the air pressure of a fan rotated by an engine so that the ignition of the ignition device is stopped to prevent accident when the engine rotates at an excessively high speed. CONSTITUTION:When an engine on a grass cutter rotates at a normal speed, a switch 37 is opened, and a condenser 53 is charged with the voltage generated in a primary coil 31 by the rotation of a magnet wheel 9 fastened on the crank shaft 7 of the engine. When the crank shaft 7 has turned to a fixed position, an ignition switch 51 is connected, and high voltage is generated in a secondary coil 33 to generate spark on an ignition plug 3. When the engine 1 has come above a fixed value of revolutions, the cooling air pressure of a fan 13 is raised, and the switch 37 is closed by a wind plate 41. Consequnetly, the circuit of the primary coil 31 is shorted to stop spark generation.
