Abstract
A fuel delivery rail assembly for supplying fuel to a plurality of fuel injectors in an engine is provided. The assembly comprises an elongated conduit and a plurality of sockets. The conduit has a four-wall section consisting of a single aluminum wall and three steel walls. Opposing steel walls are provided with cavities for receiving edges of the aluminum wall. Abutment portions between the aluminum wall and the steel walls are mechanically shrinked from outside and combined tightly. The sockets are integrally formed with the aluminum wall through an aluminum die casting process. The steel walls can be made from a high damping steel element.
