ABSTRACT:
An improved actuating fluid inlet manifold for a plurality of hydraulically-actuated fuel injectors. The manifold includes fluid dynamic tuning apparatus for controlling the flow of relatively high pressure actuating fluid between the common rail passage of the manifold and the injectors. The fluid dynamic tuning apparatus includes a predetermined flow restriction defined in each of the rail branch passages of the manifold. Advantages of the fluid dynamic tuning apparatus include improved injector performance and/or a reduction in structural stresses of various engine components.
