“…These characteristics of biodiesel reduce the emissions of CO, UHC, PM in the exhaust gas compared with diesel fuel [5][6]. Considerable research has been conducted to investigate the properties of biodiesel and its performance in engines [7][8][9][10][11][12][13][14][15]. Since the majority of modern diesel engines have direct injection (DI) fuel systems, these engines are more sensitive to fuel spray quality than indirect injection engines.…”

In this work experimental and theoretical investigations were carried out on a single cylinder, direct injection diesel engine operating on different blends of a soybean methyl ester (SME) with diesel fuel. The effect of blending on the cylinder pressure, heat release rate, carbon monoxide (CO), unburned hydrocarbon (UHC), nitrogen oxides (NOx), and smoke opacity were measured. The results indicate that the use of biodiesel produces lower smoke opacity up to 48.23% with 14.65% higher brake specific fuel consumption (BSFC) compared to diesel fuel. The measured CO emissions of B20% SME and B100% SME were found to be 11.36% and 41.7% lower than that of diesel fuel respectively. All blends of SME were found to emit significantly lower UHC concentration compared to that of diesel over the entire load. NOx emissions are observed to be higher for all blends of SME. The experimental results are compared with the results of Diesel-rk software and a good agreement between them is noticed.

“…Recently, the top CO2 emitters; China and USA agreed to cut greenhouse gas (GHG) emissions by 28% and 20%, respectively, by the year 2030. Many advantages of using biodiesel as an alternative fuel can be found in [1][2][3][4][5][6][7][8][9][10]. Zhu et al [1] and Deepak et al [11] have reported that modern diesel engines can operate using biodiesel with significant reduction in emission and without a major change to their design.…”

The ignition characteristics of palm oil biodiesel and conventional diesel fuels are simulated using the two stage Lagrangian (TSL) 0-D modeling technique. For the diesel fuel surrogate, thermochemical and reaction kinetic data of n-heptane detailed mechanism was utilized. For the palm biodiesel, simulations were done using the reduced mechanisms for the palm oil biodiesel using mixture of methyl decanoate, methyl decenoate and n-heptane as surrogates. Validations of the simulated data were performed against experimental results. The simulation results were able to reproduce the experimental trends in the ignition delay. The chemical kinetic processes responsible for controlling ignition were investigated using the TSL model.

“…In published experiments the effects of different types of biodiesel blends on combustion and the exhaust emissions and performance of diesel ICE (see [8][9][10][11]) were studied. Anand et al [8] used a nondispersive infrared analyser (NDIR) (AVL DiGas 444), gas analyser, and smoke meter (AVL437) and measured the emissions of blends of waste cooking oil methyl ester from B10 (10% by volume biodiesel in diesel) to B80 in a single-cylinder diesel engine.…”

“…Nabi and Hustad [10] employed a gravimetric method and examined the 20% in volume jatropha biodiesel blend in diesel in a six-cylinder turbocharged direct injection engine, and found that smoke decreased with the use of blended fuel. Zhang et al [11] used a portable exhaust gas analyzer (FGA-4100) along with a smoke opacity meter (AVL 439) and investigated the combustion and emission characteristics of soybean methyl ester biodiesel blends in a single-cylinder direct injection engine at different loads and constant speed. It was found that smoke opacity decreases with higher percentage of biodiesel blends [11].…”

There is a recent interest for the utilisation of renewable and alternative fuel, which is regulated by the European Union, that currently imposes a lower limit of 7% by volume of biodiesel fuel blend in diesel fuel. The biodiesel physical characteristics, as well as the percentage of biodiesel blend in diesel fuel, affect the injector nozzle flow, the spray characteristics, the resulting air/fuel mixture, and subsequently the combustion quality and emissions, as well as the overall engine performance. In the present study, two different types of pure biodiesel fuel, namely, methanol-based biodiesel and ethanol-based biodiesel, were produced in the laboratory of Frederick University by chemical processing of raw materials. The two biodiesel fuels were used for blending pure diesel fuel at various percentages. The blends were used for smoke emissions measurements of a diesel internal combustion engine at increasing engine speed and for increasing engine temperatures. From the experimental investigations it was found that ethanol-based biodiesel blends result in higher smoke emissions than pure diesel fuel, while methanol-based biodiesel blends smoke emissions are lower compared to pure diesel fuel.
