摘要： In some examples, a fuel injector rail assembly may include a fuel rail including a tubular body, with a fuel outlet passage formed through a wall of the tubular body. An injector cup may be connected to the tubular body and may include an injector chamber configured to receive a fuel injector. A first fuel passage formed in the injector cup may include a first diameter, and the first fuel passage may be connected to the fuel outlet passage of the tubular body. Additionally, a second fuel passage may be formed in the injector cup between the first fuel passage and the injector chamber. The second fuel passage may have a second diameter that is smaller than the first diameter of the first fuel passage.
