This research paper is focused on an experiment conducted on a Four Stroke Compression Ignition Engine Test Rig at different loads using a Fabricated Catalytic Converter known as Innovative Catalytic Converter coated with iron oxide nano-particles. A gas analyzer of the model KIGAZ 310 PRO was utilized to find the concentrations of carbon dioxide and oxygen. The thermocouples installed on the test rig were employed to find the Exhaust Gas Temperatures. The results obtained from the experimentation clearly show a significant increase in the concentration of carbon dioxide, oxygen and exhaust gas temperatures after using the Innovative Catalytic Converter coated with iron oxide nano-particles. Behavioral Modeling was also later done to estimate the values of carbon dioxide, oxygen and exhaust gas temperatures at all the values of percent loads on the engine within the given range. The results from the simulation of the developed model reveal that the developed model exactly mimics the practical behavior of the selected test rig. So, it can be used to simulate the values of carbon dioxide, oxygen and exhaust gas temperatures at all the loading conditions within the range.

Wei and Hong have pointed out that air pollution has become an alarming problem than ever before owing to huge number of automobiles moving on roads. This asks for an appropriate treatment method before the exhaust from the automobiles is allowed to enter the atmosphere. Specially, the Compression Ignition engine automobiles have increased tremendously causing heavy traffic and subsequent air pollution [1]. Exhaust emissions from automobiles contain a variety of exhaust emissions among which the main pollutants are CO, HC, NOx and other particulates. All of these pollutants are formed as a result of incomplete process of combustion [2]. Ali et al. reviewed the emissions from diesel engines and the relevant technologies for treatment of exhaust. They described that the emissions from the diesel engine automobiles are one of the main culprits of contaminating the environment [3]. Ladommatos stated that the shortage in supply of oxygen leads to reduction in the formation of CO2 and water vapor leading to an increase in the formation of CO and soot particles. SO, surplus oxygen is required to reduce the concentration of CO and HC in the exhaust emissions. Oxidation of harmful emissions including CO and HC in to CO2 is necessary [4]. Baskar, P. and Kumar, A.S. analyzed the effect of oxygen enrichment on the variation of the exhaust emissions from a single cylinder diesel engine. The results clearly revealed substantial decrease in HC, CO and smoke density levels. Increasing the oxygen content facilitates the conversion of CO into less harmful CO2 along with decrease in the smoke content due to improved combustion process. The content of hydrocarbons, though very small in content also reduced post supply of extra oxygen [5]. Shojaeefard, M.H. et al. used Artificial Neural Networks for the purpose of predicting performance and exhaust emissions from a diesel engine at different conditions of load and speed. Use of a mathematical modeling and simulation software helps in easy prediction of performance and exhaust emissions at all the values of load within the range [6].
