摘要：
A pulsation damper is provided between and in series with a low pressure fuel system pipe and a high pressure pump of a fuel supply system. During startup of an engine, low pressure fuel supplied via the low pressure fuel system pipe is injected from an intake passage fuel injector. When the fuel pressure is equal to or less than a fuel pressure at which good startability can be maintained, the pulsation damper closes off communication between the high pressure fuel system pipe and the low pressure fuel system pipe using the spring force of a spring.
摘要（中）：
在低压燃料系统管道和燃料供应系统的高压泵之间提供脉动阻尼器并与其串联。 在发动机起动时，通过低压燃料系统管道供给的低压燃料从进气通道燃料喷射器喷射。 当燃料压力等于或小于能够保持良好启动性的燃料压力时，脉动阻尼器使用弹簧的弹簧力来阻断高压燃料系统管道和低压燃料系统管道之间的连通。
