Emission and Performance Characteristics of DHA Biofuel on Diesel-Powered CI Engines
Main Article Content
Abstract
This study focuses on evaluating emission rates and performance attributes of a diesel-powered CI engine run on the blends of Docosahexaenoic acid (DHA) oil biodiesel. The blends used include B10 (DHA biofuel (10%) + diesel (90%)), B20 (DHA biofuel (20%) + diesel (80%)) and B30 (DHA biofuel (30%) + diesel (70%)). The engine’s performance is assessed through Brake Specific Fuel Consumption (BSFC) and Brake Thermal Efficiency (BTE). Emission properties like Nitric Oxide (NOx), Carbon Monoxide (CO), Hydrocarbon (HC), Smoke, Carbon Dioxide (CO2) and Oxygen (O2) are also analysed. Results show a notable decrease in CO, HC, and smoke emissions for DHA biodiesel blends compared to neat diesel, though NOx, CO2, and O2 emissions increase with higher bi-biodiesel content.
