Abstract—The principle of this type of combustion is to addition of hydrogen gas to the combustion reactions of either compression or spark ignition engines. The addition of hydrogen has been shown to decrease the formation of NOx, CO and unburnt hydrocarbons. Studies have shown that added hydrogen in percentages as low as 5-10% of the hydrocarbon fuel can reduce that hydrocarbon fuel consumption. The theory behind this concept is that the addition of hydrogen can increase the lean operation limit, improve the lean burn ability, and decrease burning time. To apply this method to an engine a source of hydrogen is needed. At this time the simplest option would be to carry a tank of hydrogen. Research is being conducted to allow the hydrogen to be reformed from the vehicles hydrocarbon fuel supply or produce hydrogen from electrolysis of water. In the future, better methods could be developed for storing hydrogen in the vehicle or production of hydrogen on-board the vehicle.
