Abstract

PURPOSE:To improve accelerating quality of an engine, by directly injecting fuel to a scavenging passage when the engine is accelerated. CONSTITUTION:A lever 1 is connected to an accelerating device consisting of a pump 3, operated interlocking to increase of a throttle opening, and a nozzle 4, connected to said pump 3 and injected with fuel. This nozzle 4 is mounted to an engine b respectively to appear in a scavenging passage 19 of each scavenging cylinder, and an end part of the nozzle 4 is diagonally protruded toward a scavenging port 21 opened from a wall side of the scavenging passage 19 to a wall side of a cylinder 20, then may injection holes 4a are opened to the end part of said nozzle. In this constitution, a rod 14 rushes into the pump main unit 5 in accordance with clockwise turning motion of the lever 1, and this causes a piston 7 to compress a pump chamber 6, then fuel in this chamber 6 is press fed to the nozzle 4.
