Ignition device for two-cycle engine

TLDR: In this paper, the authors proposed to improve self-cleaning work of a spark plug and prevent smoking and wetting damage of the spark plug, and ignite the dense air-fuel mixture securely for combustion by providing a current break type ignition and a capacity discharge type ignition.

Abstract: PURPOSE:To improve self-cleaning work of spark plug, and prevent smoking and wetting damage of the spark plug, and ignite the dense air-fuel mixture securely for combustion by providing a current break type ignition means and a capacity discharge type ignition means CONSTITUTION:A spark plug 50 is connected to an ignition device 52 electrically This ignition device 52 consists of a current break type ignition means 53 and a capacity discharge type ignition means 54 At this stage, electric spark is thrown from the ignition means 53 to the spark plug 50 at a point near a compression top dead center to ignite the air-fuel mixture for combustion When a piton is pushed down by the combustion explosion of the air-fuel mixture and an exhaust port starts to be opened, the electric spark is thrown from the ignition means 54 to the spark plug 50 Consequently, carbon adhered to an electrode of the spark plug 50 can be burned off for elimination Besides, since the spark connection time of the ignition means 53 is long, chance of igniting the air-fuel mixture is increased
