The re quest to develop the engines that are able to run without air or with very little oxygen condition is raised with the interest of ocean science or the mines. This research had already be gun before the world war Ⅱ, but had been stagnant owing to the appearance of nuclear power. Recycle diesel engines have ability to run under the above -mentioned condition. the recycle diesel engine recirculates exhaust gases into intake port and consumes additional oxygen supplied by oxygen tanle Carbon dioxide is controlled by the absorber. The combustion and emission characteristics of recycle diesel engines are quite different with conventional one because the working fluids of recycle diesel engines consist of Ar, CO₂ and O₂ as well as N₂.
Recycle diesel engine is therefore different with general diesel engine from the viewpoint of intake air composition. It is required to investigate the effect of intake composition on the combustion and emission to know recycle diesel engine. In this study, NOx concentration, smoke and cylinder pressure are measured with the variation of Ar and CO₂ Reduces show that the addition of Ar reduces NOx but increases smoke. Otherwise CO₂ reduces smoke and NOx simultaneously. Only CO₂ increases the ignition delay and both gases increase fuel consumption Ar addition is superior to CO₂addition for the performance of recycle diesel engine system but CO₂has the avantage with respect to emission.
