Carl,

I’d like to thank you and Walt Block for your assistance today in the Mileage Tests performed on a 1982 Chevrolet 6.2 Diesel Pickup truck.

After today’s tests Walt and I reviewed the results: We confirmed a 14% to 17% mileage improvement using Our Hydrogen Boost Technology.

Here are the test details:

Test Vehicle: 1982 Chevrolet 6.2 Diesel, 135 HP, 240 Lbs Torque, as built at factory

Dynamometer used: Super Flow Model 602 Dynamometer

This test sequence was selected to mimic the pattern of a trash truck, in town delivery truck, etc. that has frequent stops and starts.

Set load on vehicle at 40% to 45%.
Note the starting mileage on odometer and the starting fuel level on the site gauge on the external fuel tank.
Run without Hydrogen at 15 mph for 1/10^th of a mile, stop, run another 1/10^th mile, stop, and repeat sequence for several miles.
Stop the test. Note the ending odometer reading and the ending fuel level on the site gauge.
Set load on vehicle at 40% to 45%.
Note the starting mileage on odometer and the starting fuel level on the site gauge on the external fuel tank.
Run with Hydrogen at 15 mph for 1/10^th of a mile, stop, run another 1/10^th mile, stop, and repeat sequence for several miles.
Stop the test. Note the ending odometer reading and the ending fuel level on the site gauge.

We based our results on the following data:

Without Hydrogen:
Ending Odometer reading:   82356.6              Starting fuel reading :   3.9
Starting Odometer reading:  82352.8               Ending Fuel reading:    3.1
                                                -------------                                                ------------
Miles run without hydrogen:          3.8    Fuel used without hydrogen:      8 units x .125 =
                                                                                                                                      1 gallon
3.8 / 1 Gal = 3.8 miles per gallon Without Hydrogen On Demand

With Hydrogen:
Ending Odometer reading:   82362.6         Starting fuel reading :   2.8
Starting Odometer reading:   82357.6        Ending Fuel reading     1.9
                                                    -------------                                        ------------
Miles run with hydrogen:                 5.0         Fuel used with hydrogen: 9 units x .125
                                                                                                                              = 1.125 gal
5 / 1.125 Gal = 4.44 miles per gallon With Hydrogen On Demand

Percentage calculation: ((4.4 -3.8) / ((4.4+3.8)/2)) x 100 = 14.63% mileage improvement.

The equation for determining the percent difference, (assuming both x₁ and x₂ are positive), by comparing values x₁ and x₂ is:

$\mathrm{%Diff} = \cfrac{|x_1-x_2|}{((x_1+x_2)/2)}\times100$

In sentence form, one is dividing the absolute difference of the two values by the average value of x₁ and x₂. Because this equation contains the absolute function, percent difference will always be positive and therefore it does not matter which value one assigns to the variables (x₁ and x₂) used in these equations shown in this article.

This particular truck could not take more than a few minutes on this large dynamometer without damage to the engine or transmission, so the sampled miles had to be smaller than desired.

However these numbers were closely recorded and are an accurate representation of the results achieved.

Sincerely,
Richard A. Connors, President
