The present invention relates to a fuel injection arrangement for a diesel type engine configured to use carbonaceous aqueous slurry fuels. The fuel injection arrangement includes an injector nozzle for injecting fuel into a combustion chamber; a pump chamber housing a fuel pumping element for generating a pressurised fuel flow to the injector nozzle along an injection path between the pumping element and the injector nozzle; and a check valve connected to a fuel supply for regulating and supplying fuel to the injection path via a check valve outlet. A region immediately downstream of the check valve outlet defines an outlet region and the check valve is arranged to expose the outlet region to the pressurised fuel flow to facilitate flushing of the outlet region during fuel flow between the pumping element and the injector nozzle.

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.

Biomass is processed into a slurry (Heavy Biofuel Oil or HBFO) comprising a fuel slurry suitable for low and medium speed diesel engines or other suitable power equipment that is produced by subjecting biomass feedstock to steam explosion processing, washing and separating unwanted materials, micronization to a targeted size, de-ashing with high pressure steam combined with micronization, and separation by means of classification of unwanted materials and a slurrification processes to make the HBFO suitable for use in internal combustion engines, such as diesel engine systems.
