Crack emissions with emulsions, says fuel company 17 September 2014

London mayor Boris Johnson is being urged to back fuel emulsions to reduce pollution, rather than recommending a ban on diesel vehicles.

The call comes from SulNOx Fuel Fusions, which says that, by mixing diesel and water into a static emulsion, an cut NOx (nitrogen oxide) emissions and significantly reduce particulate matter (PM).

The company points out that the benefits of adding water to diesel have long been known, but until now there has been no solution to 'stratification' – when water and fuel separate into their component parts.

Stratification, says SulNOx director Stephen Bamford, has "baffled scientists for decades".

"Thanks to the application of nanotechnology and the addition of our revolutionary emulsifying agent, we have overcome this problem," he insists.

"By altering the size of the particles being burnt at a nano-level, we can significantly improve the burning process, reducing emissions and without any costly modifications."

Earlier this year the firm staged a public test, in front of the London Mayors' Association, when it used emulsified fuel in an unmodified 1959 Routemaster bus – PM was cut by 91% and NOx emissions by almost 60%.

To validate these results and continue testing the new range of fuel emulsions, SulNOx has commissioned engineering consultancy Ricardo and is in talks with Cambridge University.
