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.

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.
