Improvement on the combustion of a hydrogen fueled engine

Abstract More and more attention is being paid to hydrogen as a future fuel. Hydrogen has the intrinsic physical—chemical characteristics of wide ignition limits, high flame propagation rate and low ignition energy. By using hydrogen, the combustion process in engines can be improved and the rapid burning of the lean mixture in them can be realized, thus leading to improvements both in fuel economy and in emission characteristics of the original engine. The experimental results of burning hydrogen fuel, hydrogen-gasoline mixed fuel and hydrogen-diesel oil mixed fuel in the engine to improve the combustion processes are discussed.
