SulNOx held a successful public test of the SulNOxEco Fuels last week at the London Bus Museum. The fuel was trialled on a 1959 Routemaster bus, resulting in a reduction in particulate matter of 91%. Nitrogen oxide emissions decreased 60%, when compared with the use of normal diesel on the same engine.
Stephen Bamford, Director of SulNOx Fuel Fusions, said the trial was “an historic moment in the world’s fight against pollution”.
“The benefits of adding water to diesel fuel has been known about since the early 1900s, but the problem has been stratification of the emulsion and the excessive cost to consumer.
“The problem is water and fuel don’t mix. Over a relatively short period of time these two components separate, and as every engineer knows, putting pure water into a combustion engine has catastrophic results”.
The company told an audience at the Museum that they have overcome this by developing a new mixing process that smashes the fuel together, repeatedly at great speed and under high pressure to alter the mixture at a nano, or quantum level. An additive is then injected into the mix, which helps to further stabilize the emulsion, that can then by burnt just like regular fuel in any engine that burns hydrocarbon based fuel.
Bamford continued: “The challenge facing every country and company is how to reduce their emissions of toxic gases and particulate matter, while still remaining competitive”.
“By altering the size of the fuel particles being burnt at a nano-level we can dramatically improve the efficiency of the combustion engine by using stable emulsion without the need for costly modifications.
“This solution has the dual benefit of cutting pollution without damaging the economy”.
The company will be targeting the marine sector, considered the world’s worst polluters by environmentalists, because the biggest 16 ships produce as much pollution as all the cars in the world put together. Bunker fuel used by ships contains 4% sulfur, 4500 times more than is allowed in car fuel in the EU.
This means that ships can emit as much as 5000 tpy of sulfur, the equivalent of 50 million cars. Emulisifed fuel could potentially cut this, but will require further testing and development before these results can be confirmed.
