Rotten test run - need help!
Did an HHO test run in a diesel RV. The bus is a full size coach at 40,000 lbs. Engine is a Detroit diesel 8V-92, 2-stroke. Displacement is of course 92 cubic inch per cyl. the math puts it at 12 liters. I built 2 dry cell units each with 2 stacks configured with 9 neutrals per stack. Between both cells there was 44 plates. the plates measured 5.25 by 7.5 inches with a 1/2 wide gasket. After several tests I found the best gasket thickness was .25 inch. Total output was a steady 12 liters per minute drawing 60 amps per dry cell.
We filled the tank drove 182 miles and refilled at the same pump. Mickey (the bus owner) said he got a steady 5.7 mpg before HHO. Our test mpg was 6.1 mpg. This was an increase of only 7%. I was very discouraged wit a .4 mpg improvement. We were hoping to get perhaps 1.5 mpg or better.
Would love to get any advice or input you guys have as to what to do to improve results.
