Abstract:
1. A mounting arrangement, comprising: a fuel rail; a fuel injector cup connected to the fuel rail, the fuel injector cup having a fuel communication area defining a longitudinal axis, a fuel rail mounting section, and a retaining surface; a fuel injector including a fuel metering end and a fuel outlet end, the fuel inlet end being exposed to the communication area; and a fastener that (1) allows the fuel injector to reciprocate along the longitudinal axis of the fuel injector cup and to limit reciprocation of the fuel injector along the longitudinal axis in a direction toward the fuel injector cup and away from the fuel injector cup, the fastener having a wall and a pair of legs projecting from the wall, the pair of legs straddling both the fuel injector cup and fuel injector, the legs and wall each having a respective length along the longitudinal axis, the length of the wall being less than the length of each leg, and (2) secures the fuel injector to the fuel injector cup during an environmental vibration test that includes, while vibrating the mounting arrangement for a minimum of 15 hours in a longitudinal, lateral, and vertical direction at varying frequencies no greater than 600 Hz sinusoidal, subjecting the mounting arrangement to at least: (1) a thermal cycle test over a range of approximately −40 to 140° C.; and (2) a pressure cycle test of at least 30,000 cycles over a range of approximately 0 to 1500 kPa.
