In this research, experimentally investigate convection heat transfer of Exhaust Gas Recirculation system with an array of square fins and fin spacing of 10, 20, and 30 mm and fin height 5 mm,10 mm,15 mm. By changing the surface temperature by varying the input power of the heating element.To measure the temperature of various points on each EGR. We used six thermocouples and measured its temperature under the steady-state condition. In addition, average natural heat transfer coefficient increases to a certain value and then decreases when fin spacing increases .In Exhaust Gas Recirculation system Nitrous Oxides are formed at higher Temperature. These Nitrous Oxides are Very harmful For Environment. To Improve Heat transfer Characteristics of EGR pipe by placing Fins at different spacing and height such that it reduces temperature of Exhaust gases so that it helps in reducing Nox pollutants from Diesel Engines. For this Purpose we used fins with 10mm spacing & height 5 mm, 20 mm spacing & height 10mm and spacing 30 mm &height 15 mm and heat transfer like convection heat transfer coefficient and convection heat transfer rate are observed.
