Automobile Emissions Control
Automobile Emissions Control
Abstract - The Automobile emissions control focus on the different types of technologies that have been introducing from early 1960’s to reduce the air pollution. They describe the different control methods involved in all the devices employed for the purpose of controlling pollution. This paper entails the information of impact of using these control techniques and devices. The detrimental effects of pollutants from automobile emissions on environment and on human beings are also covered.
I. INTRODUCTION Automobile emissions control covers all the technologies that are employed to reduce the air pollution-causing emissions produced by automobiles. Emission control systems have been incorporated into automobiles to prevent pollution by limiting the amount of partially burned and evaporated gases into the atmosphere. These systems have been efficient in reducing the pollution caused by automobiles to a large extent.Exhaust emissions control systems were first required on 1966 model year vehicles produced for sale in the state of California, followed by the United States as a whole in model year 1968. Their use became widespread in the following decades and now they are ubiquitous in industrialized nations and common in most others [pic] Emissions controls have been highly successful in reducing the emissions produced by motor vehicles in terms of quantity per distance traveled. However, substantial increases in the distance traveled by each vehicle, and equally substantial increases in the number of vehicles in use, have meant that the overall reduction in pollution has been much slower.
II. EMISSIONS
The emissions produced by a vehicle fall into three basic categories.
[pic] A. Exhaust emissions. B. Evaporative emissions. C. Life cycle emissions
A. Exhaust Emissions These are the most common form of vehicular air pollution emissions. These are the emissions which
