Experimental investigation on Impact of Hot and Cold Exhaust Gas Recirculation on Diesel Engine with Cetane Improver

Today most of the transport vehicles in countries like India where cost effective is the predominant criteria utilize diesel engines rather than petrol engines. From past 5 years usage of diesel engines was rapid which can be addressed from the sales report of many automobile companies. The reason behind this could be cost of diesel fuel and efficiency of the diesel engine when compared to petrol engine. But when we look on the worse side of diesel engine, emissions from diesel engine are high especially NOx. So there is a need for a technique which could reduce the emissions without affecting the performance of engine. One such technique could be Exhaust gas recirculation and adding cetane improver to the fuel. To enhance the performance and reduce the other emissions other than NOx cetane improver di tert butyl peroxide (DTBP) was used. Present paper aims to find the impact of cold and hot EGR on emissions of diesel engine along with cetane improver.
