PERFORMANCE ANALYSIS AND RECIRCULATION OF DIESEL ENGINE EXHAUST GASES

Abstract

A diesel engine is an internal combustion engine that sparks a fuel spray at the starting of compression stroke by using highly compressed air. Diesel engine emission consists of gases such as Oxygen (O2), Carbon Monoxide (CO), Carbon Dioxide (CO2), Nitrogen Oxide (NO), Nitrogen Dioxide (NO2), and Hydrocarbons (HC’s). An exhaust gas analyzer can measure these parameters in percentage or ppm. Diesel fuel is a mixture of hydrocarbons which would produce only carbon dioxide (CO2) and water vapor (H2O).Also, diesel exhaust gases are primarily composed of CO2, H2O and the unused portion of engine charge air. The objective of this paper is to do analysis of engine performance and emissions analysis of the exhausted gases of diesel engines with Exhaust gas analyzer and recirculate them with EGR.
