Effect of Cone Angle on Performance of Catalytic Converter Ch.Indira Priyadarsini, Dr.T.Ratna Reddy, Mr.N.Chandra Sekhar, R
Journal of Information and Computational Science ISSN: 1548-7741 Effect of Cone Angle on Performance of Catalytic Converter Ch.Indira Priyadarsini, Dr.T.Ratna Reddy, Mr.N.Chandra Sekhar, R. Hathiram Assistant Professor, Mechanical Engg. Dept., Chaitanya Bharathi Institute of Technology Hyderabad, [email protected] Associate Professor, Mechanical Engg. Dept., Chaitanya Bharathi Institute of Technology Hyderabad, [email protected] ABSTRACT Catalytic converter plays a vital role in reducing harmful gases, but the presence of catalytic converter increases the exhaust back pressure. Catalytic converter is the main pollution control device for modern vehicles in order to reach the ever-increasing legislative demands for low emission standards. in this work a flow analysis is carried out by varying four different Cone angles 45o, 60o. The velocity, pressure and temperature flow in converter has been presented for different configurations. It is observed velocity profile is uniform for 450 cone angle compared to 60 and even back pressure also less with 450 angle for pipe diameter of 0.018m. Keywords— Cone angle, Catalytic converter, CFD, Fluent, Performance I. INTRODUCTION A catalytic converter is a device used to reduce the emissions from an internal combustion engine (used in most modern day automobiles and vehicles). Not enough oxygen is available to oxidize the carbon fuel in these engines completely into carbon dioxide and water; thus toxic by-products are produced. Catalytic converters are used in exhaust systems to provide a site for the oxidation and reduction of toxic by-products (like nitrogen oxides, carbon monoxide, and hydrocarbons) of fuel into less hazardous substances such as carbon dioxide, water vapour, and nitrogen gas. -

Raja Shangaravel3 Head R&D, Sharda Motor Industries Ltd., Chennai, Tamil Nadu, India1 Assistant Manager R&D, Sharda Motor Industries Ltd., Chennai, Tamil Nadu, India2 Senior Engineer R&D, Sharda Motor Industries Ltd., Chennai, Tamil Nadu, India3 ABSTRACT: Manufacturing elements that are affecting design parameters, the performance and durability of exhaust catalytic converter was analyzed. Catalytic converters with different outlet pipe insertion lengths were designed and adopted for virtual analysis. Prediction from Computational Fluid Dynamics(CFD) modeling shows insertion length of outlet pipe is inversely proportional to UI &ΔP characteristics. However, required minimum insertion length need to maintain to achieve optimum FOS for the system. According to American Weld Standard(AWS) the minimum overlap of parts in stress carrying lap joints overlap length for lap joint for fillet weld should be five times of its thickness. In this paper what happens when the performance and durability of catalytic converter varies with increase in overlap length of the outlet cone. These prediction of performance data's were verified using bench tests. The paper will discuss in detail the experimental procedures, data acquisition and data handling that were followed. KEYWORDS: Pressure drop, Uniformity index, Durability, CFD, FEA, Cold flow bench. I. INTRODUCTION In an automobile exhaust system catalytic converter and muffler are important components to reduce emission. -

Dhanalakshmi and M.Suresh Faculty, Department of Mechanical Engineering, Sri Sairam Engineering College, West Tambaram, Chennai-600 044, India ABSTRACT Catalytic converters play a major role in automobiles which reduce the harmful gasses from engine exhaust significantly. The three way catalysts (TWCs) are widely used in automobiles for the past 25 years and are more successful (20). The aim of our work is to reduce the harmful gasses, by replacing conventionally used noble materials by comparatively cheaper and economically viable Silver (Ag). CATIA V5R15 software is used to create geometric model of our catalytic converter. To oxidise HC and CO, at a higher rate atmospheric air is injected inside the catalytic converter at constant pressure. The presence of oxygen in the exhaust gas helps to increase the oxidation process (13). This work is aimed to reduce harmful gases from diesel engine exhaust.

Air pollution is predominately emitted through the exhaust of vehicles. Pollution control is playing an key role to control the upcoming generation and toxic emissions like CO, HC, NOx and soot (particulates). Plan of this research study is to reduce the emissions from the automobiles through develop and manufacturing of Copper Cerium oxide based catalytic converter by replacing the existing costly Nobel metals such as Platinum, Palladium, and Rhodium. Copper Cerium oxide will get ready by using Sole-gel method. The obtained gel will coat on the wire mesh substrate. Keywords: Emission, Types of catalytic converter, Catalyst preparation steps, Fabrication of new Copper Cerium Oxide wire mesh catalytic converter, Experimental testing rig, Results and discussion I. INTRODUCTION A Today, one of the toughest challenges faced by the mankind is the increasing of pollution at an alarming rate. It is causing an environmental imbalance and contributing to increase in the greenhouse effect. Automobile pollution is the major source of pollution. The majority of the environmental pollution is due to the three- wheeler and four wheeler automobiles due to their large number.
