Emission Characteristics for Single Cylinder DI Diesel Engine with EGR (Exhaust Gas Recirculation) System

This paper includes experimental investigations of various exhaust gas recirculation rates on engine emission characteristics like NOx, HC, CO, CO2, exhaust gas temperature by AVL gas meter. By passing exhaust gas from venturi meter and regulating it with EGR valve so as to find out its effect on critical NOx emission and other harmful HC,CO & NOx emission parameter. So to reduce such harmful gases exhaust gas recirculation is economical and effective method to control emission. We cant reduced it 100% but up to little bit extent we can reduce it from CI as well as in SI type of CI engine. Some external coupling technology like EGR of cold type installed with turbo intercooler, hydrogen, oxygen enriched air to displace fresh intake air volume and so reduced amount of oxygen in combustion chamber to control peak temperature of cylinder. in this paper we have also look toward some coal trapping method installed with dampener cause to break bond between NO at high temperature.
