A method of formulating a fuel emulsion composition for use in a specified compression ignition engine in which the fuel composition includes a hydrocarbon petroleum distillate purified water, alcohol; and an , additive composition comprising various ingredients. The types and amounts of the fuel and alcohol are selected so that the sum of its net heating value (lower heating value * percent of total composition) and the net heating value of the additive composition yields a net heating value of the aqueous fuel composition that is within the operating parameters for fuel heating values for the engine.

Why it's free to use
- Filed December 10, 1998 and granted February 22, 2011. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended December 10, 2018.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by December 10, 2020.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
