TL;DR: In this paper, the effect of hydrogen addition on a natural gas engine's thermal efficiency and emission was analyzed using variable composition hydrogen/CNG mixtures (HCNG), and the results showed that hydrogen enrichment could significantly extend the lean operation limit, improve the engine's lean burn ability, and decrease burn duration.
