Design analysis and fabrication of Innovative waste heat recovery System and its impact on emission Control in a compression Ignition engine

Abstract

Global energy demand is increasing constantly, due to various reasons such as transportation of people, products, excess population and industrial purposes, the researchers are exploring novel ways to meet the energy demands. From the fuel energy supplied, the diesel engine utilizes only a maximum of 30% whereas the rest of the energy is wasted for cooling and exhaust gases. 40% of the fuel energy is wasted in exhaust gas whereas 30% is received by the engine crankshaft. The remaining amount of heat energy remains unused in cooling system as well as in friction losses. The fuel cost increase and amendment of stringent emission norms all over the world have drawn special attention upon Internal Combustion Engines(ICEs). This made the researchers to pay serious interest towards maximizing effective utilization of available heat energy and reducing the level of harmful pollutants emitted by the engines. The present research investigates the energy recovery potential of exhaust gases in ICEs aiming at low grade waste heat energy and its impact on the corresponding harmful gas emissions. newline
