Credible Testing at The University of Hertfordshire

For some time we have been asked for VEFRIFIABLE, INDEPENDENT, ACCURATE LABORATORY tests to prove that our product works.

In the past with thousands of happy customers, 30-day money back guarantee’s and our own in house testing we knew it works.

However, as many other HHO companies have failed to produce any results when tested in this way it was obviously a concern of some people and bodies, such as the Advertising Standards Association, Transport for London, etc. The following test was completed under our new trading name of WATERFUELCELL.
We are the only HHO company in the world to have proof that our systems work backed by an independent University who are willing to put their name and reputation to the accurate results!

The Test

On 16th December 2013, we paid for credible independent Laboratory testing at Hertfordshire University Automotive Facility for the day. 

Why University of Hertfordshire

We watched a program on TV, Channel 4′s ‘Fifth Gear’ where they tested five ‘fuel saving’ products at the University of Hertfordshire.

All failed to improve fuel economy and in two cases made it worse. These tests were completed at the University by the Senior Lecturer, Gareth Williams PhD, and his staff running the Automotive facility. We then contacted him and arranged for testing using our fuel cell system and some other devices on the market which we found in our own testing to make no difference in fuel saving which was consequently confirmed.

Test Equipment used

Dyno Dynamics Rolling Road
Sykes Pickavant Advanced 5 Gas Diesel analyzer SP550
Bespoke PC software plus PC

Test Vehicle (shown above)
Vauxhall Astra 1.7cdti Van 100BHP 2007, 105,987 miles.

This vehicle has a common rail injection system. Yes the number plate is real, not made up!

So how was it tested?

Dr. Gareth Williams has devised an ingenious way of testing fuel economy with extreme accuracy. It involves a separate external fuel tank which is weighed before and after each run completed on the Dyno. The amount of fuel used is measured to a thousandth of a gram. He has a mathematical formula that works out exactly the miles per gallon used, which in turn gives us the differences in fuel economy to an accuracy never before possible.

We completed various runs starting with a base line run with the vehicle in standard stock form and likewise finishing with a stock run to confirm the original results. We then tested it with the fuel cell system only, then various different electronic systems including some third party electronics (mainly for our own development research).

Before each individual test a horsepower run was undertaken at maximum revolutions in every gear (five gears not using six). Then a setting of 3000 revs was held in 4th gear for 5 minutes duration. The astonishing results are shown below.

Best fuel economy result was 81.9 miles per gallon or 3.4 litres per 100 kilometres

The Vehicle manufacturer states the best this vehicle can ever attain is 65MPG, so that’s just over a 20% fuel increase

The second part of the testing was to test for harmful emissions. We had to wait several weeks before testing while the five gas diesel test machine was calibrated by the manufacturers. The gases tested were as follows:

1/ Carbon Monoxide.

2/ Carbon Dioxide

3/ Hydrocarbons

4/ Oxygen

5/ Oxides of Nitrogen.

Best Results as follows:

Gas                                    Baseline           With fuel cell system (best)         %reduction

Carbon Monoxide           (Not working)                  (Not working)                  (Not working)
Carbon Dioxide                   4.3                                   4.1                                  -4.88%                        
Hydrocarbons                     6.0                                   1.0                                  -500%
Oxygen                               15                                    12.1                              -23.97%

NO                                     618                                   110                             -461.82%

It was unfortunate that the CO was not working on the day, however, we will be returning the vehicle to the university when this is corrected.

Future testing very soon

We also will be testing another vehicle with a different engine configuration with a mechanical diesel injection type system in the near future similar to the Black Taxi cabs.

However the results speak for themselves but does poses the question….how can we reduce emissions and improve fuel economy by so much more than the motor manufacturers with their multi-billion budgets??

You must look to the Governments and fuel companies who would lose some of their revenue if this fuel system was utilized on a worldwide scale for the answer.

We were not surprised the CO2 was not reduced dramatically, in fact, from our testing this emission and the CO usually increases initially before dropping significantly.

The Reason?

 According to Dr. Stephen Samuels at Oxford Brooks University, a world leading expert in Thermodynamics, this happens because the HHO gas starts to remove the old carbon (soot) deposits from the inside of the engine when the fuel cell system is switched on.

Once the old Carbon deposits have been removed, the emissions drop significantly.

We will publish the final results here when we return to the University for the next stage.

We tested for horsepower also just for reference as this is not relevant to our core directives.

Interestingly however, the overall horsepower increased from 102.2BHP to a best of 111.4BHP. This confirms also that the vehicles engine and electronics were working perfectly and it was in a healthy condition. The manufacturer suggests it will have around 100BHP.

This is in line with our and customers experience of ‘feeling’ more power and response from the engine. We are also hoping to test the engine temperature on a future test.
