Fuel supply rail with integrated fuel injector load spring

摘要

A fuel supply rail assembly (30) includes a plurality of fuel injector-receiving housings (34) for mounting on a cylinder head (12) of an internal combustion engine and a plurality of fuel injector load springs (50) with each spring disposed in each fuel rail housing (34) in a manner to bias a fuel injector received therein within a preselected injector load tolerance range relative to the cylinder head (12).
