<p>This invention relates to a novel hydraulically actuated fuel injector for an internal combustion engine. More particularly, the application pertains to a hydraulically actuated gaseous injector for injecting main fuel and optional pilot fuel into an internal combustion engine at different times at controlled pressure. A hydraulically actuated fuel injector for a piston displacement engine comprising: (a) an injector (2) which is actuated by an actuator means and injects fuel into the engine (5) at predetermined times; (b) a means (1) for introducing hydraulic oil into said injector; (c) means for pressurizing said hydraulic oil; (d) means for opening a fuel inlet means (6) and injecting the fuel into the engine (5) upon the pressure of the hydraulic oil reaching a predetermined level; and (e) a means (7) for preventing the pressure of the hydraulic oil from rising above the predetermined level.</p> |
