Abstract
The present invention provides an improved fuel injection system and related method for controlling fuel heating and circulation in diesel type engines configured to use carbonaceous aqueous slurry fuels. The fuel injection system comprises: at least one fuel injector including an injector nozzle through which fuel is atomised and a fuel injector pump for pressurising fuel for supply to the injector nozzle; and a controlled bleed valve fluidly connected to each fuel injector and positioned to allow a controlled amount of carbonaceous aqueous slurry fuel to flow from the fuel injector.
Claims28
A fuel injection system of a diesel type engine configured to use carbonaceous aqueous slurry fuels, the fuel injection system comprising:
- at least one fuel injector including an injector nozzle through which fuel is atomised and a fuel injector pump for pressurising fuel for supply to the injector nozzle;
- and
- a controlled bleed valve fluidly connected to each fuel injector and positioned to allow a controlled amount of carbonaceous aqueous slurry fuel to flow from the fuel injector;
- wherein the controlled bleed valve comprises at least one of an electronically controlled bleed valve or a hydraulically controlled bleed valve.
