When i used to work at Jiffy Lube a guy came in with a 92 XJ he had 296000 miles he ran a kit that let him switch from city driving to town driving to high way driving and he told me that he got 7 MPG better from factory he told me that it tripped the MAP sensor into running lean and he had some sort of hydrogen kit on it also but i didnt ask about that

 

He probably installed it the week before. It probably didn't live to see the next oil change.


...unless he already figured out the Lucas and Zero Water secret...

 

I forgot to mention that if the oxygen isn't vented, the HHO will compress back into water molecules during fuel compression. I saw plans for a "water implosion generator" that used this idea to run an engine on nothing but HHO. The difference was that the timing was changed almost 180 degrees. Normally, the pistons compress the fuel just before TDC, and then combustion occurs pushing the piston over the TDC hump and down. With the water implosion generator, the chamber is combusted just after Bottom Dead Center so that the compression action turns the HHO into water and the suction pulls the piston towards the top of the chamber.

The popular mechanics article isn't too specific about the voltage/amperage the water was electrolyzed at, or what grade of stainless steel was used for electrode plates. I hate to tell Popular mechanics, but they overlooked a few important details...Like separating the gases before introducing the hydrogen into the engine, as well as how far the gas travels from the electrolysis unit to the intake. Also, those 8 little electrolysis units can't cycle enough water to produce the gas volume needed to see a marked increase in mileage...

The only thing I believe he got right, was the fact that the computer has to be modified to allow the engine to run a bit leaner. A controller with a potentiometer can be spliced in to make the computer receive normal O2 readings while actually running lean. The controller and electrolysis units can be turned off, enabling the vehicle to still pass emissions tests.
