What is it about?
A porous medium is a medium to retain the heat inside a combustion chamber to help achieve a complete combustion which in turn helps in achieving better performance and lower emission levels, especially in diesel engines.

Why is it important?
We have reduced some of the emission gas level using porous medium which is a zirconium based porous material.The reduction in emission on NOx, CO with porous medium and conventional type CI engine were progressively found to be increased with 69% & 23% respectively on maximum load conditions.
Perspectives
There is reduction in the formation of NOx and particulate emissions (soot formation) by achieving the homogeneous combustion inside the combustion chamber. Consequently, temperature distribution inside the combustion chamber gets constant.
