Abstract

A hydrogen enriched CNG engine can be stably operated at ultra lean condition and reduce emission extremely. It also has advantage to increase gradually the use of hydrogen for the coming hydrogen-energy age. In this studies, the combustion and emission characteristics of heavy-duty hydrogen-CNG engine were investigated to verify the enhancement of performance by enriched hydrogen into natural gas. The results showed that a hydrogen-CNG engine could achieve ultra lean operation and low emission, while power was reduced by the decrease of intake air flow.
