Fuel

Abstract

An improved fuel, particularly an improved transport fuel composition is provided. Alternate fuels to traditional oil derived petrol and diesel have been considered particularly for transport purposes. However, there are limitations that have prevented their widespread use. A fuel composition is provided for use in an internal combustion engine comprising an organic carrier fuel having a particulate additive dispersed therein, the particulate additive being a lubricant.

1 . A fuel composition for use in an internal combustion engine comprising an organic carrier fuel having a particulate additive dispersed therein, the particulate additive comprising a lubricant. 
     
     
         2 . The fuel composition according to  claim 1  wherein the organic carrier comprises or includes alcohol. 
     
     
         3 . The fuel composition according to  claim 1  wherein the organic carrier fuel comprises or includes an ether selected from Dimethyl Ether (DME) and/or Methyl Tert-butyl Ether and/or biodiesel and/or pyrolysis oil. 
     
     
         4 . The fuel composition according to  claim 1  wherein the particulate additive comprises a graphitic carbon material. 
     
     
         5 . The fuel composition according to  claim 1  wherein the particulate additive has a high graphitic carbon content. 
     
     
         6 . The fuel composition according to  claim 4  wherein the particulate additive comprises carbon char, and wherein the carbon char may comprise biochar. 
     
     
         7 . The fuel composition according to  claim 1  wherein the particulate additive is dispersed through the organic carrier fuel, and the organic carrier fuel is stored for use in liquid form. 
     
     
         8 . The fuel composition according to  claim 1  wherein the particulate additive comprises individual particles having a maximum dimension of less than 20 microns. 
     
     
         9 . The fuel composition according to  claim 8  wherein the maximum particle size dimension is less than 1 micron, and optionally less than 0.1 micron, and optionally less than 0.01 micron. 
     
     
         10 . The fuel composition according to  claim 1  wherein the particulate additive is present in the organic carrier fuel in the range of 0.1 to 2 wt/%, and more preferably in the range of 0.5 to 1 wt/%. 
     
     
         11 . A method of manufacturing a fuel composition for use in an internal combustion ignition engine comprising the steps of combining an organic carrier fuel with a particulate additive such that the particulate additive is dispersed in the organic carrier fuel. 
     
     
         12 . The method according to  claim 11  wherein the organic carrier fuel is provided in a vessel, and the particulate additive is injected into the vessel. 
     
     
         13 . The method according to  claim 11  wherein the organic carrier fuel is in liquid form when combining with the particulate additive.
