The Effects of Dill Oil Biodiesel on CI Engine Emissions and Performance

The primary cause of global warming and human respiratory problems is the impact of engine emissions from fuel combustion. The mitigation procedure for these pollutants involves altering the design of engine components or using alternative fuel sources. To effectively use biofuel, one must focus on minimizing engine emissions and addressing the issue of fuel shortages. This work specifically examined the impact of using novel forms of biodiesel derived from dill oil on the performance and emissions of CI engine. Blends of conventional Iraqi diesel fuel and dill oil biodiesel were created and mixed in volumetric proportions of 10%, 20%, 40%, 60%, 80%, and 100%. A compression ratio of 18 and a fuel injection timing of 23 degrees bTDC were the settings used for the test engine. The testing findings reveal that this particular biodiesel enhances brake -specific fuel consumption (BSFC), themass of fuel burnt rate, and exhaust gas temperature (EGT), while decreasing engine thermal efficiency (BTHE), delay period time (DP), and cylinder pressure (ICP). Also, it decreased emissions of HC, soot, and CO, but increased emissions of CO2 and NOx.
