ABSTRACT:
A fuel injection system is disclosed comprising a high pressure actuating fluid pump, a first plurality of hydraulically-actuated unit injectors, and a first high pressure actuating fluid manifold arranged in fluid communication with each of the first plurality of unit injectors. The system further comprises a second plurality of hydraulically-actuated unit injectors, a second high pressure actuating fluid manifold arranged in fluid communication with each of the second plurality of unit injectors, and a device for controlling Helmholtz resonation of pressure waves between the manifolds and/or between the pump and either manifold. Hydraulically-actuated unit injector fuel systems, having multiple manifolds for supplying high pressure actuating fluid to the unit injectors, can establish a Helmholtz resonance effect between the manifolds. The present invention controls the creation of Helmholtz resonance between the manifolds and also between the pump and either manifold.
