Fuel rail clamping arrangement
View Patent ↗A fuel rail arrangement for an engine includes a fuel rail mounting cradle and a fuel rail fixed to the cradle. The fuel rail includes one or more outlets connected to respective fuel injector pipes. The fuel rail arrangement includes a clamp to fix both the rail to the cradle and to fix the fuel injector pipes to respective outlets in the fuel rail.
1. A fuel rail arrangement for an engine, the fuel rail arrangement comprising:
a fuel rail mounting cradle including a first fuel rail mounting cradle recess and a second fuel rail mounting cradle recess;
a fuel rail received within said first fuel rail mounting cradle recess and fixed to said fuel rail mounting cradle, said fuel rail including one or more outlets connected to respective fuel injector pipes;
common fixing means to fix both said fuel rail to said fuel rail mounting cradle and fix said fuel injector pipes to respective said outlets in said fuel rail, said common fixing means includes clamping means adapted to provide a force to hold said fuel injector pipes into position to respective said fuel outlets on said fuel rail, said force additionally providing force to secure said fuel rail to said fuel rail mounting cradle, said second fuel rail mounting cradle recess receiving a camshaft of said engine therein such that said second fuel rail mounting cradle recess partially surrounds said camshaft.
2. A fuel rail arrangement as claimed in claim 1 wherein said clamping means includes bracket means which includes a bracket means recess within which said camshaft is located, and wherein said fuel rail mounting cradle and said bracket means are formed as separate components such that said second fuel rail mounting cradle recess co-operates with said bracket means recess surround and retain the camshaft.
3. A fuel rail arrangement as claimed in claim 2 wherein said bracket means includes at least one tapping or bore to allow a securing means to pass therethrough to a tapping or bore in said fuel rail mounting cradle.
4. A fuel rail arrangement as claimed in claim 2 wherein said bracket means includes at least one pipe tapping or bore to allow said fuel injector pipes to be connect and/or tightened to respective said outlets in said fuel rail.
5. A fuel rail arrangement as claimed in claim 4 including a screw adapted to cooperate with said pipe tapping or said bore to tighten to said outlets in said fuel rail.
