with the value for neat diesel fuel. Hydrogen combustion turns out into water only and it does not form any particulate matter (soot) [19].
The diminution of particulate matter is caused by the non appearance of carbon in the hydrogen fuel[22].
The high diffusivity of hydrogen than that of other fuels,increases the homogeneity of the combustible mixture and increases the availability of oxygen, thereby providing a improved condition for complete combustion [1,31]. The results of this study are similar to the results of Zhou et al. [30]
and Bose and Maji [19].
