Claims17
A crossover hose for communicating fuel between two fuel rails of a fuel-injected, spark-ignited internal combustion engine comprising:
- a polymeric tubular member having opposite end connections for joining with said fuel rails;
- a main body connected with said end connections having a flattened portion for damping pressure pulsations within said hose.
A crossover hose for communicating fuel between two fuel rails of a fuel-injected, spark-ignited internal combustion engine comprising:
- a plastic tubular member having opposite end connections for joining with said fuel rails;
- and
- a main body connected with said end connections and forming a U-shape channel therewith, said main body having a flattened portion with a width generally larger than the width of said end connections for damping pressure pulsations with said hose.
A fuel rail assembly for a fuel-injected spark-ignited internal combustion engine comprising:
- first and second fuel rails, each said fuel rail formed by a tube having a plurality of injector outlets, at least one fuel rail having an inlet for receiving pressurized fuel, and each said fuel rail having orifices to allow for fluid communication between said fuel rails;
- a first crossover hose for communicating fuel between said fuel rails, said crossover hose including:
- a polymeric tubular member having opposite end connections for connection with said fuel rail orifices;
- and
- a main body connected with said end connections having a flattened portion for damping pressure pulsations within said hose.
