HHO ASSIST: Hydrogen cell used for HHO assist to help boost MPG, increase power, and reduce pollution out the tailpipe. Vehicle shown is NOT running solely on the hydrogen gas from the cell! It is running on the hydrogen-oxygen gas from the cell but also some gasoline as the programming of automotive computers won't allow fuel flow to stop, although pulling the fuse to the fuel pump could accomplish that! :) There are portions of the engine's powerband where it's pulling enough HHO gas from the cell to cause the computer to reduce the amount of gasoline being pumped into the engine than normal (it thinks the engine is running rich, so it reduces fuel flow which is where the gain in MPG comes from) but the cell is not powering the engine alone. There is some gasoline that still gets pumped into the engine (the computer's programming will not completely stop the flow of petrol during operation). We will need to create more efficient cell designs before engines will run on just the...
