<p>A system for automatically adjusting the diffuser and gasoline passage sections of carburetors. During acceleration, the passage section of the diffuser (5) is increased gradually simultaneously with the opening of the throttle valve, and a needle valve (3) for the inlet of gasoline to the nozzle is opened. A gasoline overfeed valve (43) is activated to initiate acceleration, which activation is interrupted at successive positions of the accelerator. Said overfeed valve is also activated when starting a cold engine by pulling the starter, closing its throttle valve and partially opening the acceleration valve, with the consequent increase in the diffuser and gasoline passage sections.</p> |
