Abstract
The design and manufacture of past fuel injection systems required extensive modification of the cylinder head in order to provide and actuate hydraulically actuated fuel injectors. Additionally, methods to avoid the cylinder head modifications have presented reliability concerns. The present invention overcomes these problems by providing an adapter assembly releasably connected to the cylinder head. The adapter assembly includes an adapter which has an integrally formed actuating fluid manifold and an integrally formed fuel manifold. The present invention provides a means for communicating between the actuating fluid manifold and the actuating fluid inlet passage of a hydraulically actuated fuel injector and a means for communicating between the fuel manifold and the fuel inlet passage of the fuel injector. Actuating fluid is communicated through the actuating fluid manifold and into the actuating fluid inlet passage in order to actuate the fuel injector. This results in a more reliable system which eliminates costly modifications to the cylinder head.
