In order to realize the ultra lean bum, the method of hydrogen supplement in spark ignition engine has been examined and analyzed. As the results, lean limit was extended to ultra lean region which normal combustion was impossible by gasoline fuel. It was found that the lean limit was extended, and that the combustion process was promoted. It also comfirmed the existence of suitable hydrogen mass fraction.<br/>
