Abstract: The rise in civilization is closely related to the improvement is transportation. In the development of transportation, internal combustion engine play an important role of petrol and diesel engine. This problem is increasing day by day with increasing pollution, & urbanization air pollution has been identified as one of the potential source of air pollution. The Petrol and diesel engine power automobile achieve symbol of our modern technological society but in recent time. The I.C. engine powered vehicle has come under heavy attack due to various problems created by them. One of the various problems is air pollution and this pollution problem facing the developing countries. First of all we know about pure air means it is a mixture of nitrogen and oxygen with some rare gases argon, neon etc. Now air pollution is defined as the addition of any material which will have a dangerous effect of our planet to our atmosphere. This pollution of air problem is very serious such than a one metrologies predicted recently that air could put an end to life on this planet within century. So our aim is to find out the air pollutant from petrol as well as diesel engine and control those pollutants so that we minimize the pollution problem. The main pollutant from automobile is carbon monoxide (CO), un burnt hydrocarbons (HC). Oxides of nitrogen and lead and particular emissions. Automobiles are not only sources of air pollution but also other sources like electric generation power stations (Which mainly emit sulpher oxides and nitrogen oxides) and industries processing. In advanced countries like USA the air pollutant by automobile is about 50% of total air pollutant. It is true that the pollutant from car say half kgf for single days driving. Day by day the pollutions are increased due to number of vehicles increases and hence air pollution by vehicles are also increased. The paper deals with the types of pollutants, its sources and how to control emissions from an automobile.
Keywords: internal combustion engine, air pollution, carbon monoxide, Oxides of nitrogen, unburnt hydrocarbons.
