PURPOSE:To accelerate atomization of fuel by installing a fuel-nozzle opening and closing member linked with an air valve installed onto the upstream side of a throttle valve. CONSTITUTION:An air valve 3 which turns around a shaft 5 is installed onto the upstream of a throttle valve 2, and a piston 10 for adjusting the opening degree of a nozzle opened port 7 is attached onto the edge part of the air valve 3 by a spring 12. Though the air valve 3 is opened in accordance with the flow-rate of air, the piston 10 is pressed against the spring 12, and the fuel corresponding to the amount of air is supplied from the left-side opened port of the nozzle 7. Since fuel is supplied from the position where air stream is sufficiently throttled, superior atomization is permitted, and the fuel which adheres onto the wall surface is reduced. |
