The Performance and Emission Traits of a Compression Ignition Direct Injection (CI DI) Engine Employing Mixtures of Biodiesel Derived from Waste Cooking Oil and Conventional Diesel Fuel

The study provides the experimental analysis of CI DI engine performances using blends of biodiesel (waste cooking oil) and diesel fuel. This experimental analysis has 6 permutations of blends of biodiesel with diesel in various quantity such as diesel, 100%WCO, 80% WCO diesel, 60% WCO diesel, 40% WCO diesel, 20% WCO diesel. Respective graphs depicting the correlation with multiple affecting parameters on engine performance is also presented in this paper. Based on the experimental findings, it is demonstrated that the highest mechanical efficiency achievable, at 83.54839%, is attained when utilizing 100% biofuel, surpassing all other combinations tested. Furthermore, the results indicate a proportional increase in mechanical efficiency with the rise in biofuel usage, while maintaining consistent environmental conditions. The future scope of biodiesel lies in its potential to serve as a sustainable alternative to conventional fossil fuels, offering reduced greenhouse gas emissions and greater energy security. Continued research and technological advancements are expected to enhance its production efficiency and widen its applications across various sectors.
