摘要： In an apparatus for controlling an air/fuel ratio of a general-purpose internal combustion engine (12) using mixed fuel containing alcohol and gasoline and operated at a desired engine speed inputted by the operator while a throttle opening is regulated such that a detected engine speed converges to the inputted desired engine speed, a fuel injection amount determined for mixed fuel based on fuel injection amount characteristics is increased/decreased when a load is kept constant and the output air/fuel ratio is estimated to correct the fuel injection amount by the estimated air/fuel ratio, while a switch (knob 50) is installed to be manipulated by the operator to switch the fuel injection amount characteristics.

摘要： A fuel feed system of an engine is provided with a gas-fuel separating unit for separating oil mist generated in an engine case from air with a labyrinth, and an auto fuel cock is operated by pressure pulsation of the air from which the oil mist is separated by the gas-liquid separating unit. Thus, infiltration of the oil mist into the auto fuel cock is suppressed to the minimum, and a malfunction of the auto fuel cock caused by accumulation of the oil can be prevented. Additionally, a breather passage for feeding the air, from which the oil mist is separated by the gas-liquid separating unit, to a breathing unit is connected the auto fuel cock via a negative pressure tube. Thus, it is unnecessary to provide a specific passage for transmitting the pressure pulsation of the air in the engine case to the auto fuel cock.
摘要翻译：发动机的燃料供给系统设置有气体燃料分离单元，用于将发动机壳体中产生的油雾与具有迷宫的空气分离，并且通过气雾的压力脉动来操作汽油燃料旋塞，由气液分离单元分离。因此，将油雾渗透到汽油燃料旋塞中被抑制到最小限度，并且可以防止由油的积聚引起的汽油燃料旋塞的故障。此外，用于将由气液分离单元分离的油雾的空气供给到呼吸单元的通气通道经由负压管连接到自动燃料旋塞。因此，不需要提供用于将发动机壳体中的空气的压力脉动传递到汽车燃料旋塞的特定通道。
