Abstract :

The automobiles play an important role in the transport system. With an increase in population and living standard, the transport vehicles as well as car population is increasing day by day. In addition to this there is a steep increase in the number of two wheelers during the last two decades. Vehicular Exhaust emissions of some popular automobile models will be assayed for regulated parameters of carbon monoxide (CO) and hydrocarbons (HC) Carbon di-oxide (CO2 ) and Nitrogen oxide (NO) for gasoline powered vehicles. Production of 2-wheelers and 3-wheelers vehicle has been expanding rapidly over the past several years, especially in the urbanized areas of Asia. These vehicles emit substantial quantities of pollutants such as hydrocarbons (HC), carbon monoxide (CO), nitrogen oxides (NOx) and particulate matter (PM). These pollutants have significant adverse health effects and deteriorate environmental quality. Presented in this project are the results of experimental studies carried out to investigate the 2-wheeler emissions (CO2 , CO, NOx, and HC) by an on-board measurement method in a sub-urban area- Chidambaram. Total number of fourty 2-wheelers vehicles randomly selected relatively between the 1990-2012 model years at various places. Vehicles of various makes and models are in use in Chidambaram. The most common among the two wheel gasoline vehicles are Hero Honda motor bike (4 stroke, 100cc), Yamaha motorbike (2stroke 100cc) Tvs jive motorbike, Tvs flame motorbike 125cc, Bajai platinum motorbike, Tvs XL motorbike, Apache motorbike, Bajai Discover 135cc motorbike, Bajaj Pulsar 150cc DTS-I motorbike and Honda Unicorn motor bike etc. The real time values were compared with standard ones, and the level qualified. Emissions from motor vehicles have substantially changed over the last decade because of new fuels, changed engine designs, and improved emission-control technology.
