Study on Hydrogen as a Substitute Fuel for Engines

Hydrogen is a new renewable energy resources which causes low pollution while burned. In the paper , the problems in operation of hydrogen-fueled engine are summarized , and a plan to improve the combustion in hydrogen-fueled engine is put forward. The research shows that abnormal combustion can be cont rolled and operation performance can be improved by means of high pressure injection for spark ignition and optimum selection of injection timing and ignition timing.
