Investigation On Diesel Engine Performance By Injecting Di-Ethyl Ether As An Additive With Exhaust Gas Recirculation Using Diesel Particulate Filter

Abstract

Diesel engines are the main power source for the automobiles but emission norms are strict for any engine. Among the main pollutants PM, NOx, CO, HC, SOx, aldehydes most harmful pollutants of diesel engine are NOx and PM. Exhaust gas recirculation (EGR) is effective for the reduction of NOx emission from engines but also reduces efficiency. This happens due to accumulation of burnt gases in combustion chamber. Diesel Particulate Filters (DPF) are designed to reduce the mass emissions of diesel particulate matter and have proven to be effective in this aspect. The aim of this work is to analyze the effect of EGR on the engine performance and exhaust emission characteristics. The work carried out on the four stroke four cylinder Diesel engine. Experimentation involves the addition of oxygenated fuel Di-Ethyl Ether with the Diesel fuel. The results showed the increase in brake thermal efficiency and decrease in specific fuel consumption with increase in EGR valve opening due to the supply of extra oxygen molecule by the additive. Further, a significant reduction in the emissions of PM, NOx, HC, CO was observed with the application of DPF into the exhaust of engine.
