Abstract

A mounting assembly for a vehicle fuel delivery system includes a mount body having a fuel injector receiving portion, a resonator portion, and a fuel rail attachment portion. The fuel injector receiving portion includes a fuel delivery passage and the resonator portion includes an internal cavity having a cavity outlet adjacent to an inlet end of the fuel delivery passage and a cavity inlet for receiving fuel with pressure waves of an estimated or known frequency. The internal cavity and the cavity inlet together define a resonator that is tuned to resonate at a frequency that is out of phase with the estimated or known frequency to cancel at least a portion of the pressure waves.
