Emmision control in two wheeler using catalytic

converter

The main content of our project is to develop an eco friendly environment by reducing pollution mostly in highly rushed traffic’s porn area’s . We have developed a small change in the earlier design of converter’s where the inner shell has been slightly modified and bought a platinum coated shell which allows to reduce the emmision and makes the vehicle to run more eco friendly, earlier it was made in heavy vehicle’s but we have made out in two wheeler’s

ABSTRACT

Catalyst's Simply put,

catalysts are substances which, when added to a reaction, increase the rate of reaction by providing an alternate reaction pathway with a lower activation energy (Ea).

In biochemistry, catalysts are known as enzymes

The catalytic converter was invented by Eugene Houdry , a French mechanical engineer and expert in catalytic oil refining  who lived in the U.S. around 1950. Catalytic converters were further developed by a series of engineers including  John J. Mooney  and  Carl D.Keith creating the first production catalytic converter in 1973

INTRODUCTION

CATALYTIC CONVERTERCatalytic

converters are found in automobiles.

Their role is to reduce to emissions of harmful gases (CO, VOC’s, NOx) that are the result of the combustion of fuel in vehicle engines

METHOD OF OPERATION OF THETHREE-WAY CATALYTIC CONVERTER

Specifics of Catalytic Converters Most modern cars are

equipped with three-way catalytic converters. "Three-way" refers to the three regulated emissions it helps to reduce -- carbon monoxide, and NOx molecules .

The converter uses two different types of catalysts, a reduction catalyst and an oxidization catalyst. Both types consist of a honeycomb-shaped ceramic structure.

The main salint feature’s for the working is the catalytic converter. The emmision taking place in the engine will be lebarated through the exhaust valve and then goes out into the atmosphere here the exhaust from the engine is taken into the converter of platinum filled shell which absorbs the exhaust toxic gases and then goes to the environment which will almost emmit’s the gases coming out , which will reduce the gases of 80% of what exhausted than the earlier .

Working principle

Lambda sensors are not used to adjust the engine mixture but simply to identify the performance of the Catalytic Converters .

Used in vehicle’s to reduce the emmision .Used as a non-toxic agent.

Application's

Used to reduce the toxic gasesHigh efficincy of performance’sLow costHigh durability of core working

Advantage's

We construct a project successfully. On completing the project we come to a conclusion that constructing a mechanical project is a good experience. This project will surely make a change in the environment by running such kind of eco friendly vehicle which make the world to stay more longer.
