Abstract
In this study, exergy, energy, performance and emission analysis were investigated for the repurpose used cooking oil (RUCO), Jatropha curcas (JC), Pongamia Pinnata (PP) and petroleum diesel fuel (PDF) fueled compression ignition engine under various engine loads. In this study, 20% of each biodiesel was tested in single cylinder, four stroke, diesel engine, given that open literature shows the potential use of biodiesel of up to 20% in a diesel engine without modification. The diesel engine was used to investigate their performance, combustion and emission characteristics of diesel-repurpose used cooking oil, Jatropha curcas, and Pongamia Pinnata fuel samples at different compression ratios and load condition. The results showed that thermal efficiency is higher with the PDF compared to DRUCO20, DJC20, DPP20 biodiesel blends. The exhaust gas temperature decreased and specific fuel consumption of the engine were increased by adding RUCO, Jatropha curcas, Pongamia Pinnata to petroleum diesel fuel. Engine ecological analysis showed that blended fuel reduces the average hydrocarbons (HC), carbon monoxide (CO) and NO X than petroleum diesel fuel. While DRUCO20 showed better performance and reduction in ecological analysis but higher ecological of CO 2 is comparable with DCJ20 and DPP20.
