Low toxicity fuel and lubricant for two-stroke engines

Abstract

A low toxicity fuel and lubricant for two-stroke engines includes a fuel component that is based on ethanol and includes 2-25% volatile hydrocarbon fractions, and a lubricant component based on an oil that is soluble in ethanol, for example castor oil.

1 . A fuel and lubricant package for two-stroke engines, including a fuel component that is based on ethanol and includes 2-15% volatile hydrocarbon fractions, and a lubricant component based on an oil that is soluble in ethanol, wherein the fuel component includes 85-95% ethanol, the lubricant component is based on a vegetable oil or an equivalent synthetic oil, the lubricant component is combined with the fuel component at a rate of 1-4 cc per 100 cc of the fuel component, and the fuel and lubricant package has a low toxicity. 
   
   
       2 . A fuel and lubricant package according to  claim 1 , wherein the ethanol and hydrocarbon is blended for high octane and low toxicity. 
   
   
       3 . A fuel and lubricant package according to  claim 1 , wherein the fuel component includes 3-15% volatile hydrocarbon fractions. 
   
   
       4 . A fuel and lubricant package according to  claim 1 , wherein the volatile hydrocarbon fractions are selected from the group consisting of pentane, iso-pentane, butane, iso-butane, propane and combinations thereof. 
   
   
       5 . A fuel and lubricant package according to  claim 1 , wherein the fuel component includes one or more additives selected from the group consisting of corrosion inhibitors, combustion enhancers, solubility aids and cold starting promoters. 
   
   
       6 . A fuel and lubricant package according to  claim 1 , wherein the fuel component includes 3-10% water. 
   
   
       7 . A fuel and lubricant package according to  claim 1 , wherein the lubricant component is based on castor oil. 
   
   
       8 . A fuel and lubricant package according to  claim 1 , wherein the lubricant component is based on jojoba oil. 
   
   
       9 . A fuel and lubricant package according to  claim 1 , wherein the lubricant component includes one or more additives selected from the group consisting of corrosion inhibitors, solubility aids and detergents. 
   
   
       10 . (canceled) 
   
   
       11 . A fueled engine comprising a two-stroke engine and the fuel and lubricant package according to any one of  claims 1  to  9 .
