Abstract

Vehicular exhausts are responsible for more than half of the carbon dioxide emissions in / the Earth’s atmosphere. In response to this, researchers have been looking at hydrogen as a / replacement for gasoline because its only byproduct is water, and this significantly reduces / carbon dioxide emissions. This research focuses on a comparison of gasoline and hydrogen / efficiency and the return on investment for each. It was hypothesized that the gas­hydrogen / motor would be more work efficient. Hydrogen is more combustible than gasoline and would be / less expensive in the long run. For the gas­hydrogen one would only have to pay for the / hydrogen kit and smaller amounts of fuel whereas for gasoline only one would have to / continuously pay for larger amounts of gasoline. Trials were run for the engine using gasoline / only and for the engine using a combination of gasoline and hydrogen. A hydrogen production / kit was added to the regular gasoline engine to make it a hybrid for the gasoline­hydrogen trials. / Fuel efficiency was tested by timing how long it took for 25 mL of fuel to consumed. Hydrogen, / produced through water electrolysis, was included in the fuel consumption by introduction / through the air intake. The gasoline motor had a run­time mean of 11.490 minutes and a standard / deviation of 0.885 minutes. The gas­hydrogen motor had a run­time mean of 17.564 minutes and / a standard deviation of 0.928 minutes.
