Abstract
A wear resistant, reduced stress at increased injection pressure fuel distributor assembly for distributing high pressure fuel to the fuel injectors of an internal combustion engine is provided. The assembly includes a fuel distributor rotor with a surface profile configuration that effectively and efficiently distributes high and low pressure fuel to the fuel injectors without internal fuel distribution channels. The rotor is preferably formed from a high thermal expansion, wear-resistant ceramic or coated metal material.
