導入するための第１および第２のエアーブリード
と、このうちの第２エアーブリードを開閉する制
御バルブを備え、この制御バルブはエンジン温度
を感知する温度感知手段により制御される駆動装
置で操作され、エンジン温度がある設定温度以上
となつた暖機時にのみ前記第２エアーブリードを
開いて二次側ステツプの混合比レベルを暖機時に
適合した希薄混合比とし、エンジン温度が前記設
定温度に達しない冷機時には前記第２エアーブリ
ードを閉じて二次側ステツプの混合比レベルを冷
機時に適合した濃混合比とするように構成されて
いることを特徴とする二段気化器。 It includes first and second air bleeds for introducing air into the fuel flowing to the secondary step port, and a control valve that opens and closes the second air bleed, and this control valve senses engine temperature. The second air bleed is operated by a drive device controlled by a temperature sensing means, and opens the second air bleed only during warm-up when the engine temperature exceeds a certain set temperature to adjust the mixture ratio level of the secondary step to a lean level suitable for warm-up. The second air bleed is closed when the engine temperature does not reach the set temperature and the mixture ratio is set to a rich mixture ratio suitable for when the engine is cold. A two-stage vaporizer.
