    • An internal combustion engine includes a cylinder head having a plurality of intake ports; throttle devices including a plurality of respective intake passages equipped with throttle valves therein; a plurality of fuel injection valves for injecting fuel into the corresponding intake passages; a fuel pipe adapted to supply fuel to the fuel injection valves; and a pulsation damper connected to the fuel pipe to damp fuel pressure pulsation. In the engine, a connection pipe coupled to the pulsation damper is formed between a plurality of branch portions with respect a longitudinal direction of the fuel pipe, adapted to deliver fuel from the fuel pipe to the fuel injection valves and the connection pipe is disposed to at least partially overlap the fuel injection valve as viewed from the longitudinal direction of the fuel pipe.
    • 内燃机包括具有多个进气口的气缸盖; 节流装置包括在其中配有节流阀的多个相应的进气通道; 多个燃料喷射阀,用于将燃料喷射到相应的进气通道中; 燃料管,适于向燃料喷射阀供应燃料; 和连接到燃料管的脉动阻尼器以阻止燃料压力脉动。 在发动机中,连接在脉动​​阻尼器上的连接管相对于燃料管的纵向方向形成在多个分支部分之间,适用于将燃料从燃料管输送到燃料喷射阀,连接管设置在 从燃料管的纵向方向观察燃料喷射阀至少部分重叠。
