摘要:
A fuel rail includes an elongated tube having an inlet and a plurality of outlets. The elongated tube defines a fuel passageway for directing fuel toward the plurality of outlets. The fuel rail also includes a plurality of baffles positioned within the elongated tube to divide the fuel passageway into a plurality of chambers such that each outlet is positioned in one of the plurality of chambers. The plurality of baffles restricts fluid flow between adjacent chambers. A majority of the plurality of outlets are located essentially at an acoustic node of each corresponding chamber to reduce noise generated by the fuel rail.
摘要(中):
燃料轨道包括具有入口和多个出口的细长管。 细长管限定用于将燃料导向多个出口的燃料通路。 燃料轨道还包括定位在细长管内的多个挡板,以将燃料通道分成多个腔室,使得每个出口位于多个腔室中的一个中。 多个挡板限制相邻腔室之间的流体流动。 多个出口中的大多数出口基本上位于每个对应腔室的声学节点处以减少由燃料轨道产生的噪音。
