Hydrogen is in many ways an attractive clean alternative to fossil fuel. However, as hydrogen has a higher burning velocity and a shorter quenching distance than hydrocarbons, and these characteristics of hydrogen influence the degree of constant volume combustion and the cooling loss by the heat transfer from burning gas to the combustion chamber walls. The cooling loss fraction and the degree of constant volume are two of the major factors influencing the thermal efficiency of internal combustion engines. On the other hand, hydrogen has good anti-knock properties, and hydrogen engine can run with higher compression ratios than gasoline engines. This paper analyzes the influences of compression ratio on thermal efficiency of hydrogen engine.
