Testing Commercial SL50 Oxy Hydrogen Generator on Dodge Sprinter

We have a 2006 Dodge Sprinter cargo van (see picture below) for business use at DiaSolid Tools and Supplies Inc. It runs on diesel and is good on fuel – it uses 12.44 liters diesel for 100 KM (18.91 MPG) according to the average of 6 records (which correspond to 6 full tanks of filling) we had for it in the past. However, with diesel ($1.229/liter) selling higher than gasoline ($1.099/liter) – prices given are the prices at the time of this writing in Calgary, Alberta, Canada – we would like to save more money on fuel.

Before Christmas 2007, we had been searching for ways to increase fuel efficiency for vehicles we drive. Oxy hydrogen generators – both the commercial available ones and the home-made ones – caught our attentions.

We bought the commerical SL50 stainless steel oxy hydrogen generator found here last year on December 5, 2007 but only had the time to install it on our Dodge Sprinter yesterday (March 23, 2008). Here are two pictures taken after the installation was finished:

After installing the oxy hydrogen generator, we did not sense any noticeable change of engine noise – probably because it is a new vehicle (Dodge Sprinter 2006). However, one thing we did notice was that the coolant temperature did not rise up as fast as before – this makes sense as the product of burning HHO is simply water and water is the best in absorbing heat.

Also the temperature appeared to stay lower than before. Before installing SL50, the coolant temperature stayed usually around 85 degrees for city driving and 90 degrees for highway driving. After installing the oxy hydrogen generator, the temperature stays around 83 degrees for city driving. What is the temperature for highway driving? We have not tested that yet. One of our staff will be driving this cargo van to Edmonton (from Calgary) to deliver diamond tools to our Red Deer and Edmonton customers on March 8, 2008 – we should know the result pretty soon

Anyway, so far so good. We have now filled up the fuel tank with diesel and recorded the mileage meter reading. Once we have the result, we will report it here.

Note 1: We are going to run tests as well on the 2005 Toyota Sienna and 1999 Hyundai Elantra which we own and drive.

Note 2: Accidentally, we found that the water level in the plastic bubbler (marked IN above) decreased fast in the original design and also since it was made of black plastic we could not see when the water level was low. So we built one ourselves with a wide-mouth fruit jar – see picture below:

This home-made one is almost transparent and can hold a relatively large amount of water compared with the one that came with the commercial device we bought.

Note 3: To save your time of having to go over all our test entries in the comment area below, we summarize our tests here. Basically we got 31% fuel saving in our recent apple-for-apple road tests. We just need to do one more test on a longer route to confirm this. Will report here when we get that done.

Note4: I have not done it myself, but this YouTube video shows one guy in Guelph, Canada did it with his ScanGauge on his HHO generator:

From my own tests I have learned that you need to calibrate the MPG reading on ScanGauge with real tank-fill data. But the above video is the first one I’ve seen showing instant change of MPG reading with the HHO cell turned ON and OFF. Need to test this as I do have a ScanGauge II.
