Abstract
At present IC engines are experiencing with partial ignition and irregular temperature circulation inside the engine cylinder due to improper mixing of air and fuel mixture. Due to this effect, NOx , CO and Unburned hydro carbons will be released into the atmosphere. Excessive soot formation also takes place in the IC engine. To perform the homogeneous combustion inside the engine cylinder the new Porous Medium concept has been proposed. Porous Medium engine concept is mainly for reducing the emissions and improving the performance characteristics of the IC engine. Gun Metal Porous Medium has been introduced at the top of the Kirloskar 5BHP diesel engine cylinder head. When compared to conventional engine, reduction of total fuel consumption quantity up to 13%, Specific fuel consumption quantity up to 12%, increment in Brake thermal efficiency up to 12% and Indicated thermal efficiency up to 6% are obtained during part load operations. When compared to conventional engine, Mechanical efficiency has been increased up to 8%, NOx level gets reduced up to 53% and CO2 level gets decreased up to 46% from no load to full load operations.
