“…They found that 15 % castor oil methyl ester blend with diesel fuel was an optimum compared to other blends of fuel and offered a comparable engine performance parameters related to a diesel fuel. The thermodynamic and economic analysis of a diesel engine using diesel fuel and different blends of biodiesel is also reported (Caliskan & Mori, 2017). They found that, BSFC increased with increasing percentage fractions of biodiesel in blend ratios and inversely proportional to the lower heating values (LHVs) of the blends of fuel.…”

In this paper, energy, exergy, suitability and economic evaluation of a diesel engine running with diesel fuel and five different types of preheated biodiesel blends were evaluated experimentally. The experiments were carried out at varying engine brake mean effective pressures (bmeps). The energy and exergy rate components of the engine were callcualted and compared for each operating conditions and blends of fuel. The fuel properties of the castor oil methyl ester (COME) at different preheating temeperatures have been tested with a consideration of different biodiesel international standards. The test results shows that the fuel properties of COME improve with increase of fuel inlet temeperatures. At 114°C, kinematic viscosity and density decreased to (5.74 mm2/s and 862 kg/m3), whcich is close to diesel fuel, and the brake specific fuel consumption (BSFC) and brake thermal efficiency (BTHE) was improved by 33.1% and 49.6% compared to the fuel preheated temeperature of 42°C. The input fuel energy and exergy rates of blends of fuel were seen to be improved than diesel fuel. The maximum energetic and exergetic efficiency for blended fuels in the test engine at 372 bmep were found in the range of 25−28 % and 23-26%, respectively. The blends of fuel are marginally less sustainable than diesel fuel at every bmeps. The cost analyses show that, all blends of fuel offer quite higher economic cost with respect to diesel fuel. The full economic analysis reveals that only up to 60% blends of fuel is more affordable as compared to diesel.

This study presents the comparative performance analysis of WCO15 and NEEM15 fuelled diesel engine using the experimental record data. Investigations are carried out with a natural aspirated, single-cylinder diesel engine at different load conditions. Exergetic and energetic parameters are determined by using the experimental data for both biodiesel blends at constant speeds. Exergy parameters namely exergy destruction, exhaust-exergy, cooling water-exergy, energy, and exergy distributions are compared. It is observed that the exergy variation follows a similar trend of their corresponding energy. At 100% load, brake thermal efficiency for NEEM15 and WCO15 is 30.88 and 32.35%, respectively. At 100% load, the exergetic efficiency for NEEM15 and WCO15 is 28.95 and 30.48%, respectively. NEEM15 gives higher exergy destruction as compared to WCO15, which is validated with the sustainability index for NEEM15. Evaluation of engine performance based on exergy is a better option instead of energy analysis only.

In response to the escalating emphasis on sustainability across diverse sectors, this study addresses the imperative to combat environmental degradation through conscientious development. The primary focus is on assessing the feasibility of replacing fossil fuels with renewable alternatives in internal combustion engines (ICEs) equipped with direct fuel injection. The research employs energy and exergy analyses, coupled with economic analysis, to comprehensively evaluate the performance of fuels and blends. Applying the Lotus Engine software, computational analyses are conducted, taking into account the specific geometry of the engine. Simulations explore different λ‐factors to identify optimal performance configurations for each fuel or blend. Noteworthy outcomes reveal that blends featuring green hydrogen yield remarkable improvements, showing high torque (max. +11.5%), power (max. +14.35%), thermal efficiency (max. +3%), and exergy efficiency (max. +21.56%). These blends also demonstrate reduced operating costs (max. −10%), although with higher exergy losses, indicating areas for potential enhancement. Conversely, fuels containing ethanol show intermediate values between the blends and pure fuels. Consequently, this study effectively establishes the significance of these fuels in ICEs, supported by comprehensive energy, exergy, and economic analyses. The findings underscore the promising potential of renewable fuels as viable alternatives to fossil fuels, marking a substantial stride towards sustainable energy solutions and environmental preservation.
