testing a new diesel/water emulsion
testing a new diesel/water emulsion
(OP)
We are looking for a reputable laboratory to test a newly developed fuel composed of diesel and water for vehicles. Could anyone suggest one? Ideally they should be UK based near London. We are happy to pay all fees up front.





RE: testing a new diesel/water emulsion
when you say you want to have the fuel tested do you mean that you want an engine that is running the fuel to be put on a dyno or do you mean a chemical analysis of the fuel???
If you want to have the fuel tested in an engine on a dyno then there are a few companies that you might want to conside Lotus Engineering (near Norwich), Ricardo Engineering (Shoreham-on-sea) or Janspeed (Salisbury). If you want the chemical stuff done then I don't really know.
As far as the fuel being 'new' I think that Ricardo done some research on the subject of water/diesel emulsion a few years back, the benefits where said to be a reduction in Nox emissions. The biggest drawback was the tendency of the fuel to degrade (diesel and water separating) after a few weeks standing.

MAN B&W favour this approach over water injection into the air inlet. Both approaches are designed to procvide "No Smoke" operation of the engines even at reduced loads.
Fuel is a critical topic for engine manufacturers and users and hence CIMAC (the International Council on Combustion engines) at www.cimac.com has a working group on fuels.
In the UK the Society of Motor Manufacturers and Traders in London (Haldane House?)should also be able to advise on appropriate facilities.
Other than that, what happened to NIFES in Slough? the National Industrial Fuel Efficiency something or other. Are they still there?

Over this level the heat to evaporate the water, lowers the thermodynamic efficiency. It is the old trade-off again.
It probably helps the emissions as well.
In WWII tthe Spitfire went better on foggy days or in cloud for the same reason but these were carburetted not injected engines.
Universities probably have test facilities available still in their laboratories.

I hope you have found a reputable laboratory to test your work. In the future, I work for a "CERTIFIED EMISSIONS TESTING LABORATORY" here in Canada.

As far as I can recall, the tecnique of injecting water with fuel reduces emissions and fuel sensitivity but suffers from other practical problems in the field. Namely, you must carry distilled water, with an additive to prevent freezing, and use a fuel pump capable of injecting the mixture.
In DI diesel engines the fuel is often the only lubricant that some parts of the pump see, so having a significan amount of water in the fuel changes the requirements of the materials in the pump.

Any suggestions would be appreciated.
