Effect of Using Exhaust Gas Recirculation (EGR) on the Emission Characteristics of the CI Engine Fuelled by Acetone-Butanol-Ethanol (ABE) Diesel Blends 2019-01-0748

The power generation, agriculture, and transportation sectors are dominated by diesel engines due to better thermal efficiency and durability. Diesel engines are also a major contributor to the air pollutants such as NOx and particulate matter. Acetone-butanol-ethanol (ABE) is considered a promising alternative fuel as it emits less pollutants compared to conventional fuels. In current work, the ABE used was of the ratio (3:6:1) and four samples were prepared for engine trial ABE (10%90%diesel), ABE (20%80%diesel), ABE (30%70%diesel) and ABE (40%60%diesel). Their physio-chemical properties like kinematic viscosity, density, specific gravity and calorific value were checked and tested on compression ignition engine at different operating parameters. The experimental work was conducted upon Kirloskar 4-stroke single cylinder, vertical, air-cooled 661cc compression ignition engine at different speeds and loads. The operational parameters taken were injection temperature, injection pressure and injection timings. The main aim of the current work is to find the effect of exhaust gas recirculation (EGR) on the emission characteristics of acetone-butanol-ethanol (ABE) blends with diesel in compressed ignition engine. Exhaust gas recirculation (EGR) is a promising technology to significantly decrease NOx emissions from diesel engines. The EGR reduces NOx by reducing the oxygen concentration in the combustion chamber, along with this through absorption of heat. The emission characteristics were evaluated using avl gas analyzer and the results were then compared with emission characteristics of ci engine when run with pure diesel
