摘要： In a variable venturi type carburetor having a slow speed system, a fuel vapor conduit is provided, an inlet of which is open to a main fuel passage, an outlet of which is open to an intake passage. Fuel vapor occurring in the main fuel passage is carried through the fuel vapor conduit, so as not to be introduced into a slow fuel passage; thereby, the engine is rotated stably with a relatively lean air-fuel ratio.
摘要翻译： 在具有慢速系统的可变文丘里型化油器中，设置燃料蒸气管道，其入口与主燃料通道相通，其出口向进气通道开口。 在主燃料通道中产生的燃料蒸汽通过燃料蒸汽管道被运送，以便不被引入缓慢燃料通道中; 由此，发动机以相对较稀的空燃比稳定旋转。
