ABSTRACT:
A fuel injector adapted for an internal combustion engine has a cam driven pumping mechanism, a pressure intensifier mechanism, an injection mechanism, and an electronically responsive relief valve mechanism. The cam driven pumping mechanism has a pumping piston operably reciprocating to pressurize a hydraulic fluid to a first pressure. The pressure intensifier mechanism receives the hydraulic fluid at the first pressure from the pumping mechanism, and acts against fuel to pressurize it to a second pressure greater than the first pressure. The injection mechanism receives the highly pressurized fuel from the intensifier mechanism. The injection mechanism includes a check blocking an orifice in an end portion of the injection mechanism. The pressurized fluid displaces the check away from the end of the injection mechanism by the pressurized second fluid to begin fuel injection. The relief valve mechanism is connected to the first pressure chamber and operably exhausts the first pressure chamber in response to an electrical signal.
