Study and Effect of Exhaust Gas Recirculation (EGR) on the Performance and Emission Characteristics of Compression Ignition Engine.

Abstract

When used in a diesel large scale engine as power sources applications medium and heavy range, due to lower fuel consumption and lower emissions of carbon monoxide (CO) and unburned hydrocarbons (HC), compared with engines gasoline. The efficient use of natural resources is one of the basic conditions for any country to be self-sufficient. Both in the formal and informal sectors of the internal combustion engine has become the main driver is indispensable. With the increasing demand for fossil fuels, the strongest threat to clean up the environment and posed as linked to burning fossil fuel emissions such as CO2, CO, sulfur oxides, nitrogen oxides and particulates which it is currently the main source of global emissions. In diesel engines, and the formation of nitrogen oxides is a very temperature dependent phenomenon. Therefore, in order to reduce emissions of nitrogen oxides in exhaust gases, it is necessary to maintain peak combustion temperature under control. of exhaust gas recirculation is the most important to reduce emissions of NOx method. recycling portion of the exhaust gas helps in reducing nitrogen oxides, but the emission of particles observed in a high concrete loads, and therefore there is a tradeoff between NOx and smoke. For most of this trade-off of interest, and can be used to trap particles to reduce the amount of unburned particles equitable geographical representation, and this in turn reduces particulate emissions as well. The pilot conducted an investigation to control the effect of exhaust gas recirculation exhaust gas temperature and exhaust opacity. The development of this experimental system proposed experiments in a single cylinder, direct injection, air-cooled engine compression ignition. Matrix has conducted experiments to observe the effect of different amounts of equitable geographical representation in the degrees of the temperature of the exhaust gas and opacity
