Hydrogen fuel system for SUV is basically using hydrogen gas (H2) as a supplementary fuel to normal gasoline. H2 can be generated from water with electrolysis process. When electricity is passed through water, H2 is produce. The next step is to vent the hydrogen gas into the engine air filtration system. The concept is the same as shooting nitrous oxide into the engine to generate a higher engine power output. By introducing H2 into the combustion chambers, it will mix with gasoline fume and produce a bigger explosion in the engine. The end result is a smoother and stronger power from the engine.
When a SUV is consuming the same amount of gas but is achieving a higher engine output, the vehicle will cover more ground hence increasing its mileage and saving fuel. The only by product of hydrogen fuel system is pure water vapor released into the exhaust pipe.
It used to be very expensive to convert a SUV to run on water fuel. The modification process has to be done in a high tech workshop with specialist automotive engineers. Nowadays, the conversion process has been made easier and simpler. Anyone with some car maintenance skill can do it. You will need to get an instructional guide online to assist you. With the local gasoline prices hitting the roof, any ideas that can reduce the fuel cost of a SUV will be a blessing.
