Investigation of intake air temperature effect on co-combustion characteristics of NH/gasoline in naturally aspirated high compression ratio engine with sub-chamber.

Recently, ammonia (NH), which has a higher energy density than hydrogen, has gained attention for zero-carbon emission goals in the transportation sector. However, in a conventional internal combustion engine (ICE), NH combustion mechanism is still under investigation. In this paper, to further expand the knowledge on the adoption of NH in ICEs, authors conducted NH/gasoline co-combustion experiments in a modified, 17.
