Abstract

A crank case pre-compression spark ignition type two-stroke internal combustion engine, in which during the compression stroke of the piston in the combustion chamber, gas is introduced into the crank case and compressed while the piston is descending, the compression pressure is used to introduce gas into the combustion chamber through a gas discharge pathway, which is characterized in : installing a thick gas mixture suction pathway for introducing a thick gas mixture into the crank case, and a thin gas mixture suction pathway for introducing a thin gas mixture or air into the crank case, connecting the thick gas mixture suction pathway with a line of fuel supply device on the peripheral of the crank arm, and installing the thick gas mixture suction pathway at a position where the thick gas mixture flow from the fuel supply device to the crank case coincides with the rotation direction of the peripheral of the crank arm, and forming a thick gas mixture discharge pathway on the extension line of the thick gas mixture suctionpathway.
