Abstract: The invention relates to a fuel charging system having pressure pulsation damping. The fuel charging system includes a first side rail connected to a second side rail by a crossover tube. Defined within the crossover tube are first and second passageways; the first passageway including a restricted flow section therein.

Abstract: A vehicle fuel rail system for fuel delivery and liquid fuel retainment therein. The vehicle fuel rail system comprises a fuel rail and a chassis connector in fluid communication with the fuel rail. The fuel rail has a first bank and a second bank connected to the first bank by way of a crossover line. The first bank has a first top portion and a first bottom portion and the second bank has a second top portion and a second bottom portion. The crossover line has a first end disposed at the first bottom portion and a second end disposed at the second top portion. The chassis connector has a tank end and an rail end wherein the tank end is connected to the vehicle fuel tank and the rail end is disposed at the first top portion.

Abstract: The invention relates to a fuel system having pressure pulsation damping. The invention specifically locates restrictors in relation to identified critical elements of the system to control the maximum operating system pulse magnitude, as well as damping the overall pulsations of the system.

Abstract: A method of securing fuel rail dampers within a fuel rail using clips and fingers that engage the damper and rail surfaces while providing substantially no motion between the rail and the damper assembly.

Abstract: A tubular fuel pressure damper for use in a fuel rail. The tubular fuel pressure damper includes a first and second end and an inner surface defining a cavity. The first and second ends of the fuel pressure damper are closed by crimping to form contact areas. The contact areas may be additionally sealed by welding, soldering or other means.
