Abstract
A hydraulically-actuated fuel injection system is disclosed comprising an actuating fluid sump, a high pressure actuating fluid pump having a pumping chamber arranged in fluid communication with the sump, and a priming reservoir arranged in fluid communication between the sump and the inlet of the pump. Engines equipped with a hydraulically-actuated fuel injection system must be able to quickly pressurize actuating fluid in order to quickly start an engine. The priming reservoir is provided in order to prime and thereby facilitate rapid pressurization of the high pressure pump during startup of an engine.
