“CATALYTIC CONVERTER”

PREFACE
Catalytic converter is most effective device which converts harmful gases due to engine exhaust into eco-friendly gases. In this report, we have tried to bring into focus imports of reducing air pollution and why catalytic converter is necessary in automobile. We also tried to bring advance technology found out now a day for reducing air pollution. By best effort, we try to focus necessity of subject. We hope our report is one step ahead in this direction.

CHAPTER-1
INTRODUCTION
7.1 INTRODUCTION: As we know, air pollution is big challenge for the world. Air pollution is not national problem. An under developed country like India control of air pollution is very necessary. Air pollution due to industrial west, automobile & by nature. But among that air pollution due to automobile 70% of total air pollution. So now a day control of automobile pollution & its bad effect is very necessary. We have several ways for controlling automobile pollution, but most effective way is by using catalytic converter in the automobile.
7.2 CATALYTIC CONVERTER AS A POLLUTION CONTROLLER DEVICE:
The catalytic converter does a great job at reducing the pollution, but it can still be improved substantially. One of its biggest shortcomings is that it only works at a fairly high temperature. When you start your car cold, the catalytic converter does almost nothing to reduce the pollution in your exhaust.
What is catalytic converter?
As the name suggests, it basically converts harmful gases into harmless gases, which are environment friendly, with the help of a catalyst. Engine exhausts having harmful gases like CO, NOx & HC which are converted into harmless gases like CO2, N2 & H2O respectively with the use of catalytic converter.
7.3 HISTORY:
In 1973, General Motors faced new air pollution regulations and needed a way to make its cars conform to the stricter standards.

    Engineers are continually working on improving the efficiency of car engines. A more efficient engine means that a car will burn less fuel to travel the same distance reducing pollutants. This is good for car owners too because they do not need to buy so much fuel. Even a very efficient engine will still produce air pollutants. This is why scientists have developed ways of removing the worst pollutants from the exhaust. All new cars have catalytic converters fitted to their exhaust system. The waste gases pass through a metal…

    Catalytic converters are an integral part of converting much of the pollution that comes out of a car 's exhaust. Almost every car since the year 1970 has come with a catalytic converter in order to reduce harmful emissions. I chose to explain the function and chemistry behind the catalytic converter because I have an interest in cars and I wanted to know more about them.…

    With this involves combustion of a fossil fuel, a process that emits gases and affects the environment (King & Media n.d.). The U.S. Department of Transportation reported in December 1970 that over 89.9 billion vehicles travel our nation highways. However, by December 2011 that number increased to over 246.3 trillion automobiles. With such a high incline, how do automobiles affect our environment and the ozone layer? Majority of the pollution throughout our nation is caused by automobiles. The ozone layer is there to protect life from the ultraviolent rays from the sun. These layers become depleted due to high concentrations of chlorine or bromine atoms and include chlorofluorocarbons, or CFC’s, halons, methyl bromide, carbon tetrachloride and methyl chloroform (King & Media n.d.). Since the automobiles, emission gases contain few chlorine or bromine; therefore, they have little effect on depleting the ozone layers. However, the different gases and particles that automobiles emit affect our environment. Our vehicles contain different fluids such as motor oil, antifreeze, gasoline, refrigerants, and brake, transmission, hydraulic, and windshield-wiper fluids. There fluids can leak into our waterways and harm humans, animals, and fish. In addition, theses fluids pick up metals for wear and tear of the engine, which makes them more toxic to the…

    The invention of motor vehicles and the development of the automotive industry in the 20th century has led to the development of the concept of auto mobility. Cars have become a part of our life and has become difficult to live without them. For most Americans it has changed their life immensely and most wouldn't know what to do if tomorrow all cars were banned. However even with all the advances and pro's that the car has given to us it has been noted that they have been the main cause of air pollution from the emission of green house gases…

    When a car’s engine is running, several different types of gasses and particles are emitted that can have detrimental effects on the environment. Of particular concern to the environment are carbon dioxide, a greenhouse gas; hydrocarbons -- any of more than a dozen volatile organic compounds, some of which are known carcinogens; nitrogen oxides; sulfur oxides; and particulate matter, tiny particles of solids, such as metal and soot. Other emissions that affect human health and create smog include ozone and carbon monoxide. (See Reference 1) The good news is that despite the increase of vehicles on the road, air quality today is actually better than it was in the 1970s, thanks to the 1970 Clean Air Act. In fact, lead emissions from cars have been almost completely eradicated because of the phasing out of leaded gasoline. (See Reference 2, page 2)…

    Efficient has raised a question in the auto industry; by questionable about whether the world can support the efficient in cars. If a single driver in a car that is able to carry 4 to 6 for a distance of 2 to 300 miles is not so efficient when we need only commute 30 miles each day to work and back. One study is the “heat engine” which is the internal combustion engine. This efficient vehicle can have more of efficient. Cars and trucks account for more than 60 percent of U.S. oil consumption and more than 25 percent of domestic carbon pollution, environmental statistics show. The auto industry has held on to cleaner burning fuels, more efficient engines and advanced battery technologies for gasoline-electric hybrids and full-electric cars that produce few to no emissions. Automakers are growing to boost efficiency, and many cars on the road already meet or exceed the 2016 targets. General Motors and Japan 's Nissan are racing to roll out the first mass-produced electric cars later this year and other manufacturers have designs in the pipeline.…

    Specifically, technology has magnified our vision of automobiles. From luxury features to safety features, many things, such as heated seats and voice activation systems, have come from the many years of research and the testing of new technologies. I sincerely believe that with the help of new technologies, a safer and more economical environment has been created. With the inventions of hybrids, flex fuels, and components such as night vision, parking assist, and blind spot sensors, drivers are provided with cleaner and more fuel efficient alternatives, with the added benefit of safety. In fact, the Economist newspaper states that, “Hydrogen fuel-cell vehicles promise to be the cleanest mode of transportation, eliminating harmful tailpipe emissions altogether” (Economist). Increasing the number of these vehicles will help to reduce the amount of the pollution in the air, and as a result, reduce destruction and death of plants and animals, as well as, human diseases associated with the lungs.…
