通用发动机用的燃料供给设备
摘要：
本发明涉及一种通用发动机(10)用的燃料供给设备(30)，该燃料供给设备包括：化油器(42)，该化油器设置在从空气清洁器(41)延伸到所述通用发动机(10)的进气管线(31)中；减压连接通道(81)，该减压连接通道连接到所述化油器(42)的浮子室(63)和所述空气清洁器(41)；控制阀(82)，该控制阀设置在所述减压连接通道(81)中；减压泵(83)，该减压泵设置在所述减压连接通道(81)中并且抽吸所述浮子室(63)以减少其中的压力；空燃比传感器(84)，该空燃比传感器检测从所述通用发动机(10)排出的废气的空燃比；以及控制单元(85)，该控制单元基于所述空燃比传感器(84)的检测信号来控制所述控制阀(82)的打开程度。
摘要（英）：

The invention relates to a fuel supply apparatus for a general purpose engine. The fuel supply apparatus (30) for a general purpose engine (10) includes a carburetor (42) provided in an air intake line (31) extending from an air cleaner (41) to the general purpose engine (10), a pressure reduction connection channel (81) connected to a float chamber (63) of the carburetor (42) and the air cleaner (41), a control valve (82) provided in the pressure reduction connection channel (81), a pressure reduction pump (83) provided in the pressure reduction connection channel (81) and sucking the float chamber (63) to reduce the pressure therein, an air fuel ratio sensor (84) detecting the air fuel ratio of an exhaust gas discharged from the general purpose engine (10), and a control unit (85) controlling the opening degree of the control valve (82) based on a detection signal of the air fuel ratio sensor (84).
