Hydrogen (H-2) owns some excellent fuel specialties and can be used as enhancer to improve the performance of original engine. In the present survey, percent of performance improvement of a Wankel gasoline rotary engine by H-2 enrichment was experimentally studied. The tested engine was initially run at idling and then 3000 rpm with an intake pressure of 37.5 kPa. For the two tested operations, H-2 energy percent (beta(H2)) in the total energy was varied from 0% to 37.0% and 0% to 28.3%, respectively. Results indicated that engine performance was improved by extending beta(H2). Overall, performance improvement of idling was more effective than that of 3000 rpm. Percent of performance improvement of idling was generally bigger than that of 3000 rpm. Besides, performance improvement by adding H-2 was relatively efficient at low beta(H2), especially below 10%.
