Abstract

PURPOSE:To smooth a transition property upon transferring from a primary stage to a secondary by a method wherein a big amount of suction air is supplied through the primary suction air path and a small amount of the same is supplied through a sub-suction air path in a partial load zone to generate a swirl. CONSTITUTION:A carburettor is provided with an inflow port 20a at the upstream of a secondary throttle valve 18 and a nozzle 20z directed to a combustion chamber 2 at an immediate upstream of a suction valve 6. Further, the ramificated opening 26 of a secondary slow path 24 is communicated with the inflow port 20a of the sub suction air path 20. In a partial load zone, fuel is sucked through the primary suction air path 10 into the combustion chamber 2 while a small amount of suction air is sucked through the inflow port 20a and high-speed suction air is supplied to the combustion chamber 2 through the nozzle 20z to generate the swirl in the combustion chamber 2. During this period, a small amount of the fuel is continued to be supplied to the path 20 from the path 24 bia a communicating path 30. According to this method, the responding property of the fuel may be improved.
