“…The calorific value of biodiesel is lower than diesel fuel (42-45 MJ/kg), indicating biodiesel is 11.5% lower in calorific value than diesel fuel. The flash point of Jatropha oil is very high which above 200 C, then by converting the Jatropha oil to biodiesel, the flash point has reduce approximately 26% (219 C to 163 C) [83]. The flash point of diesel is much lower than biodiesel, which makes biodiesel safer to handle, store and transport.…”

Jatropha Curcas stands out as a promising plant-based feedstock, offering a non-edible oil that holds great potential as an alternative fuel to traditional diesel. Notably, Jatropha oil boasts favourable fuel properties, including a higher oil content compared to other alternatives. This attribute makes it an attractive candidate for biodiesel production. Importantly, as a non-edible oilseed feedstock, Jatropha Curcas helps mitigate concerns related to food prices and the ongoing food versus fuel debate, offering a sustainable solution to the growing energy demands. Furthermore, the plant exhibits impressive yields, with the potential to produce up to 40% oil weight per seed. This high yield not only enhances the economic viability of Jatropha-based biodiesel but also underscores its efficiency as a feedstock. The discussion extends beyond mere fuel properties, encompassing a comprehensive comparative review that delves into engine performance and emission characteristics associated with Jatropha Curcas. The novelty of this paper lies in its exploration of the crude oil aspects of Jatropha curcas, shedding light on an essential facet often overlooked. By presenting a thorough analysis of fuel properties, engine performance, and emission characteristics, the paper contributes valuable insights to the discourse on sustainable energy solutions. Moreover, it goes beyond technical aspects and provides perspectives on the current economic status, offering a holistic view of the potential impact of Jatropha Curcas in the broader context of renewable energy and economic development.

“…Using Ansys Fluent, CFD analysis for biodiesel at high ambient and pressure conditions as well as Jatropha burning characteristics in CI engines are described (Dixit et al, 2020). Many researchers worked hard to improve the Jatropha biodiesel fuel blend which ended in increasing NOx (Madiwale et al, 2018, Kavitha et al, 2019, Gautam et al, 2022, Khalaf et al, 2022, Yadav et al, 2023, D'Silva et al, 2023.…”

Diesel engines are the primary source of power in many types of transport applications, so many countries are currently working to reduce the vehicle exhaust emissions from diesel engines. Jatropha oil methyl ester was mixed in various amounts (20%, 40%, 60%, 80%, and 100%) during an experimental investigation to assess diesel engines' efficiency and emissions at different engine speeds, such as 500 rpm and steps increase with 250 till 1500 rpm. For various blending ratios at each speed, the engine was run at no load, quarter, half, three quarters, and full load. The brake thermal efficiency, the exhaust gas's temperature, and the brake specific fuel consumption (BSFC) are the performance characteristics that are assessed, whilst the exhaust emissions include the specific emissions of O2, CO, CO2, and NOx. Combustion modeling for the fuel was done using ANSYS Fluent to predict the performance and emissions for diesel and biodiesel fuels. It was found from both the simulated and the experimental results that the use of biodiesel blends causes a 21% decrease in brake thermal efficiency and a 32% increase in brake-specific fuel consumption. The use of biodiesel fuel blends results in a rise in exhaust gas temperature. Increased biodiesel content in fuel blends results in a reduction in specific emission of CO2. The results suggest that biodiesel made from oils that are not suitable for human consumption, such as Jatropha, may be a suitable replacement for diesel fuel in diesel engines.
