Ignition device for spark ignition type internal combustion engine

Abstract

Abstract PURPOSE:To reduce combustion time and operate efficient combustion, by providing a plurality of ignition gaps in a combustion chamber and igniting an air-fuel mixture at many places simultaneously. CONSTITUTION:Many electrodes b and b', c and c', ..., y and y' are fitted on the upper surface of insulation plate 4 of the flat part of the upper surface of piston. Each pair of electrodes b and b', c and c', ..., y and y' form an ignition gap. When high voltage is applied with ignition plug 6 set plus and ignition plug 7 minus, a spark is produced simultaneously in many gaps between electrodes a and a', b and b', c and c', ..., y and y', z and z'. By these sparks, the air-fuel mixture in the combustion chamber is ignited at every place on the upper surface of the piston, and even and speedy combustion is operated.
