Abstract

Abstract: In order to reduce the emissions of diesel engine, the investigation into the effect of H₂ addition on the emissions of heavy-duty diesel engines is attracting attention from researchers in recent years. The effects of H₂ addition at different proportions (the highest volume proportion of hydrogen is 7% of hydrogen air mixture in inlet pipe) on the emissions of CO, CO₂and HC in Cummins ISM370 diesel engine are researched. Research shows that the addition of hydrogen can benefit the reduction in the emissions of CO, CO₂ and THC in various loads, and has little effect on the emissions of THC. Moreover, with the increase in amount of hydrogen, the emission characteristics of CO, CO₂ and THC varies with the change of load. The amount of hydrogen added should be appropriate to load operation to reduce the emission in maximum extent.

Key words: power machinery engineering, hydrogenation, Cummins ISM370 diesel engine, CO, CO₂ and THC, emission characteristics
