Fuel modification can be conducted through the addition of nanoscale metallic, carbon, and organic additives 3, 11, 12, 13, 14, 15. Many researchers explored possibilities to enhance the properties of biodiesel Among them, fuel modification is one the powerful techniques. Despite various advantages, application of biodiesel has several shortcomings, such as low calorific value, poor cold flow properties, and combustion characteristics. Biodiesel provided promising economic viewpoint in the energy market, and positive effect on the environment 6, 7, 8, 9, 10. ![]() The other important characteristics of biodiesel include its’ availability, transportability, non-toxic, ease of blending with diesel. Also, the engine test results demonstrated that 30 ppm of ZnO nanoparticles in Mahua biodiesel (MOME2030) and diesel (D10030) with diethyl ether resulted overall enhancement of CRDI engine characteristics.īiodiesel is considered as the unsurpassed renewable fuel source due to its’ comparable diesel properties, preparation methods with high yield 1, 2, 3, 4, 5. Similarly, the TRCC cylinder bowl geometry illustrated advanced ignition due to an improved swirl and turbulence. The 7-hole fuel injector with the nano fuel blends at an injection timing and pressure of 10° btdc and 900 bar demonstrated the overall improvement of the engine characteristics due to the better air quality for fuel mixing. The cylinder pressure and heat release rate for D10030 and MOME2030 were enhanced by 6.8% and 17.1%, and 7.35% and 12.28%. For injection timings (IT) and injection opening pressure (IOP) average increase in brake thermal efficiency for fuel blend D10030 and MOME2030 was 9.65% and 16.4%, and 8.83% and 5.06%, respectively. The effects of modification of fuel injectors (FI) holes (7-hole FI) and toroidal reentrant combustion chamber (TRCC) piston bowl design on the performance of CRDI using different fuel blends were assessed. ![]() The physicochemical properties of diesel, diesel + 30 ppm ZnO nanoparticles (D10030), 20% Mahua biodiesel (MOME20), and Mahua biodiesel (20%) + 30 ppm ZnO nanoparticles (MOME2030) were measured in accordance to the American Society for Testing and Materials standards. This study deals with an experimental investigation to assess the characteristics of a modified common rail direct injection (CRDI) engine utilizing diesel, Mahua biodiesel, and their blends with synthesized zinc oxide (ZnO) nano additives. ![]()
