The currently employed heterogeneous combustion results in incomplete combustion and an uneven temperature distribution in the engine cylinder. The major effect of this improper combustion is on the efficiency of the engine. This yields high NOx, CO and HC, etc., emissions, resulting also extensive soot formation. The emission can only be improved by catalytic treatments, but such treatments, however, result in high cost and relatively low conversion efficiency. This paper suggests development of new combustion techniques to yield improved primary combustion process inside the engine for improving the efficiency with drastically reduced exhaust gas emission. The porous medium combustion technology for energy efficient and environmentally safe operations in IC engine. The main attention is focused on the engine concept having potential for homogeneous [nearly emission free] combustion process under variable engine operating conditions. The porus media can be used to great variety of improvement in combustion process. The key role of NOx reduction and soot emission elimination in homogeneous combustion engine. A brief identification and survey of porous material (PM) used in this area is also presented with their operating and limiting parameters. Homogeneous 3D thermal self-ignition, wide and dynamic power regulation, extremely low pollutant emissions, incorporation of porous medium in the cylinder head, open type-and closed type- PM – engines. for in this technique may implemented from IC engines for improving the efficiency drastically and reduced exhaust gas emission.
