Calculation and Analysis of Temperature and Pressure Drop of Exhaust Gas in the Front Pipe of Engine Exhaust

Authors(2) :-Shravan Raj K, Rakesh M

Temperature and pressure plays a critical role in the engine performance. The exhaust gases coming out of the engine needs to be treated before they are let into the atmosphere. The treatment of gases is done using various catalysts in the catalytic converter. For these catalysts to work properly the exhaust gas temperature plays a vital role. This paper deals with the creation of a tool which calculates the temperature and pressure drop of the exhaust gas in the front pipe of the exhaust system, (i.e. pipe starting from engine outlet till the gasses reach the ATS, i.e. After Treatment System) of an engine. The tool is created in visual studio using visual basis. For calculation of the temperature and pressure drop, the exhaust line is discretized into finite element of 1mm. Then the temperature and pressure drop in this finite element is calculated. The procedure is continued for the entire pipe and then the total temperature and pressure drop in the pipe is calculated.
