Increase in Gas Mileage in HHO has its Dangers!

This increase in gas mileage in HHO system was posted in Utube more than a week ago. The conversion was done on a 2006 Dodge Ram which has a rated mpg of 12-19 mpg from the manufacturer. According to him, he never went to 17 mpg since he owned the truck and this was the reason he added a HHO gas generator to the engine.

The increase in gas mileage was accomplished using a HHO generator consisting of a HHO fuel cell with an oxygen computer enhancer or EFIE. I saw all of his test previously but it was incomplete until last week. I am posting this so you will know the significance of his work:

EFIE will lean out the fuel mixture on its own even without using the HHO generator. Please take this seriously because if you do it without monitoring with a scangage, there is the danger of having a too lean fuel mixture and can raise the combustion temperature and damage the engine.

Here are some bad side effects of just using EFIE without the HHO generator:

1.) Lost of power which can be felt thru engine hesitation and cutting out at stop lights.
2.) Increase in engine temperature due to lean condition which will cause pinging or premature detonation and subsequent melting of spark plug tips and piston tops. If this happens to you then your engine is toast!

Prevention:

Always use the HHO gas from the HHO fuel cell when using the EFIE device. At the same time, monitor the scangage for signs of increase engine temperature and performance. The hydrogen gas when introduce will make up for the lean condition and give the engine power. You can also monitor the engine temperature using your dash gage.

The question now is: What is the SAFE way to get an increase in gas mileage?

Using your scangage, always set the HHO gas production to the lowest amount using the PWM adjuster. Most tests I have seen is set under 20 amp maximum setting. But test it at a small increment until you get the best increase in gas mileage without harming the engine. This can be done by watching the engine temperature always. I would also remove the spark plug frequently because that will be the first indicator if the engine mixture becomes too lean. I would start by checking the spark plugs (one spark plug will do) every time the HHO system is used then gradually increasing it every other day up to once a week. But I will never take it for a long continuous drive for more than I hour without checking the spark plugs. If it shows that driving it for over 1 hour is safe, then I would check it again after 4 hours until I am satisfied. I cannot over emphasize this because I have seen a lot of damaged engines when the fuel engine mixture is too lean.

Note when testing the increase in gas mileage:

When propane or LPG conversion was first introduced in in early 80’s in Calgary, lots of engines blew up because the fuel setting was too lean. This is how I learned first hand that getting an increase in gas mileage does not mean anything until you set the fuel mixture properly. This can be done and all you do is test it gradually as I have outlined here.

Again, this test shows that EFIE plus HHO generator will give you an increase in gas mileage. However, I wonder what would have happened if he added PWM, scan gage and MAP/MASS sensor adjuster? In the end, I will be happy with this test as long as he monitors his engine temperature and spark plugs. Of course if you do this test yourself, you know what to do after reading all my post about HHO testing.
