摘要: An engine fuel injector includes an internal fuel passage in which pressure waves can develop upon opening and closing of an injection valve. A fuel pressure damper is associated with the fuel passage and operates to vary the internal volume of the fuel passage in a manner to reduce the amplitude of pressure variations and pressure waves in the fuel passage. A variety of fuel pressure damper embodiments are disclosed.
