The pollusion problems in our country are increasing day by day. Euro 2000 norms came to reduce the pollusion problems. Now a day LPG vehicles are more preferred due to this reason.

Atmospheric pollusion from automobiles mainly occured from the fuel tank, the carburattor, the crank case and the exhaust system. One of the main method to reduce pollusion from engine is to introduce positive crankcase ventilation valve (PCV valve) in between the crankcase and intake manifold. Other methods to reduce pollusion from different parts are

Emission Control Techniques
1. INTRODUCTION
The need to control the emissions from automobiles gave rise to the computerization of the automobile. Hydrocarbons, carbon monoxide and oxides of nitrogen are created during the combustion process and are emitted into the atmosphere from the tail pipe. There are also hydrocarbons emitted as a result of vaporization of gasoline and from the crankcase of the automobile. The clean air act of 1977 set limits as to the amount of each of these pollutants that could be emitted from an ....etc

Petrol vehicles uses device called carburetor for supplying the air fuel mixture in correct ratio to cylinders in all rpm ranges. due to construction of the carburetor is relatively simple, it has been used almost exclusively on gasoline engines in the past. However in response to recent demands for cleaner exhaust emission, more economical fuel consumption, improved drivability, etc., the carburetor now must be equipped with various compensating devices, making it more complex system. ....etc

Emission Control Technology for Stationary Internal Combustion Engines


INTRODUCTION
Internal combustion (IC) engines are used in a variety of stationary applications ranging
from power generation to inert gas production. Both spark ignition and compression ignition
engines can be found. Depending on the application, stationary IC engines range in size from
relatively small (~50 hp) for agricultural irrigation purposes to thousands of horsepower for
power generation. Often w ....etc

THE IMPACT OF TRANSPORTATION CONTROL MEASURES ON EMISSION CONTROL DURING THE OLYMPIC GAMES IN BEIJING

1. INTRODUCTION
1.1 GENERAL

Emissions from vehicles come from the by-products of the combustion process which takes place inside the vehicle when it moves. In addition to this, volatile organic compounds (VOC) also escape through fuel evaporation. As vehicle exhaust systems have improved, evaporative emissions have become a larger component of total vehicle VOC emissions
