Introduction: Emissions and existence of abundant carbon particulates in the atmosphere, turns the planet into a green house and traps the temperature. Factories, electronic appliances used at home are sources of release of carbon particulates. However the primary source of carbon emissions has been motor vehicles that run on petroleum or diesel as fuel. Earlier the number of cars was less and the emission norms were not formed to control the excessive carbon emission. Today the number of cars has risen drastically. Even though the emission norms are strict and gave a set emission level for each automobile that is registered, damage to the environment can’t be controlled. Internal combustion Engines: There are various types of engines that have been used over the time, since automobiles were invented. Internal combustion engines have been the most used and dominating form over several years, due to their efficiency and reliability compared to other engine types. Fuels majorly used with these engines are gasoline and diesel, converting chemical energy into mechanical energy. In this process by-products are emission of carbon particulates and aerosol lead. Recirculating the carbon particulates from exhaust back to inlet, has negative effect on the efficiency of the vehicle, which is negligible, can reduce the carbon emission from the engine. Large reductions in the emissions of NOx and carbon particulates are recorded by following that methodology. (Zhao et al., 1998)
