  • Abstract:
  • The quantity of crude oil is continuously declining, which forces researchers to create new sustainable alternative fuels, particularly biofuels. The project’s main aim is to optimize the diesel engine operation on biodiesel concerning performance and emission and to find optimum engine parameters using the hybrid AHP- Topis method. In direct-injection (DI) diesel engines, algae methyl esters are used as biodiesel. The general best biodiesel mixture AME20 (80% diesel and 20% algae methyl esters) is used. The engine injection pressure was varied from 200 bar to 240 bar in 20-bar increments. The outcomes demonstrated that AME20 injection pressure adjustment enhanced emissions and diesel engine performance. Algal oil is obtained from the microalga Scenedesmus obliquus. A 20% biodiesel blend was created. The fatty acid composition of S. obliquus affects its fuel properties. Blend20 is similar to diesel oil in terms of its chemical and physical characteristics. A study was done on the performance metrics and exhaust emissions of a diesel engine burning diesel fuel and biodiesel blends. The biodiesel blend showed improved thermal efficiency, reduced exhaust gas temperature, and decreased specific fuel consumption. B20 produced fewer gas emissions than biodiesel. In this paper, compression ratio (CR) and injection parameters such as injection time (IT) and injection pressure (IP) are used to determine the performance and emissions of DI diesel engines using biodiesel (0%, 50%, and 100%). Experiments were performed using CR 18, Its (19, 20, and 27), and IP (200, 220, and 240 bar) (200, 220, and 240 bar).
