COMBUSTION AND PERFORMANCE ANALYSIS OF KARANJA, JATROPHAAND COTTON-SEED OILBASED BIOFUEL AS SUBS....

Biofuel has established itself as a primary source of substitute fuel and is poised to become a future renewable energy source. Because of its renewable source and lower emissions, biodiesel has emerged as a viable diesel fuel substitute. The utilisation of non-edible filtered Jatropha (Jatropha curcas), Karanja (Pongamia pinnata), and Cottonseed oil based biodiesel blends with diesel as alternative fuels in diesel engines was investigated. The goal of the current research was to see if biodiesel could be employed in a single cylinder compression ignition engine used in agricultural applications in India. For the testing, diesel and biodiesel from Jatropha, Karanja, and Cottonseed, as well as their blends (10 to 50% by volume), were employed (0, 50, 75 and 100 percent ). The combustion parameters of the engine were calculated, including peak pressure, heat release rate, and performance. According to combustion study, Karanja biodiesel produces the highest peak cylinder pressure (5.32 bar). The results show that when the test engine was run on JME (Jatropha Methyl Ester) and CSME (Cottonseed Methyl Ester), the engine performance was somewhat lower and the combustion characteristics were slightly different than when the engine was run on diesel. Biodiesel lowers carbon dioxide (CO2) and unburned hydrocarbon (HC) emissions while increasing nitrogen oxides (NOx) emissions. The Karanja biodiesel showed improved heat release properties.
