“…used TGA to show that PM derived from pure biodiesel exhibited the fastest oxidation rate compared to ultra-low sulfur diesel and synthetic Fischer-Tropsch fuel. Sukjit et al 15. demonstrated that the oxidation temperature of PM decreased when using rapeseed biodiesel (RME) or oxygenated additives (butanol and castor oil methyl ester).…”

This paper focuses on oxidation reactivity and nanostructural characteristics of particulate matter (PM) emitted from diesel engine fuelled with different volume proportions of diesel/polyoxymethylene dimethyl ethers (PODEn) blends (P0, P10 and P20). PM was collected using a metal filter from the exhaust manifold. The collected PM samples were characterized using thermogravimetric analysis (TGA), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and Raman spectroscopy. The TGA results indicated that the PM produced by P20 had the highest moisture and volatility contents and the fastest oxidation rate of solid carbon followed by P10 and P0 derived PM. SEM analysis showed that PM generated from P20 was looser with a lower mean value than PM emitted from P10 and P0. Quantitative analysis of high-resolution TEM images presented that fringe length was reduced along with increased separation distance and tortuosity with an increase in PODEn concentration. These trends improved the oxidation reactivity. According to Raman spectroscopy data, the intensity, full width at half-maximum and intensity ratio of the bands also changed demonstrating that PM nanostructure disorder was correlated with a faster oxidation rate. The results show the use of PODEn affects the oxidation reactivity and nanostructure of PM that is easier to oxidize.

“…The increase in smoke emissions with increasing the engine operating loads for both engine speeds tested is found. This is attributed to the high overall equivalence ratio and the number of fuel rich regions in the combustion chamber when the engine is operated at high load, resulting in the high critical conditions for soot formation which relates to the increase in smoke emissions [15]. The addition of castor oil and ethanol in diesel fuel tends to decrease the smoke emissions at all conditions tested.…”

“…However, this drawback of castor oil is expected to recover a substantially reduction of viscosity due to the addition of alcohol to diesel fuel. The utilisation of COME as blend component to extend the use of alcohol-diesel blend were studied in previous works [15], [16]. The results showed that the combination of alcohols with COME improved the most relevant fuel properties of the blends which influence the combustion process closer to diesel fuel.…”

Castor oil which is produced from non-food crop and contains high proportion of ricinoleic acid was added to ethanol-diesel blend, forming the ternary blend. The extremely high viscosity and good lubricating properties of castor oil were expected to restore the substantial reduction in such fuel properties due to the presence of ethanol in the blend. The basic physical and chemical properties of the test fuels were measured according to ASTM standards and the engine test was conducted on a four-cylinder direct injection diesel engine with naturally aspirated and water-cooled system. The experimental results showed that the high viscosity, density, flash point of castor oil can help to improve the properties of the fuel blend due to some poor properties of ethanol leading to keep the fuel properties of the ternary blend under the limit of diesel fuel specifications. The emission benefits of the reduction in CO, NOx and smoke emissions were obtained by the combustion of the ternary blend without the significant increase in THC emissions at high engine operating loads, compared to diesel fuel combustion. It is evident that the incorporation of castor oil and ethanol as blend components to reduce the use of diesel fuel for compression ignition engines is a feasible alternative for next generation fuels. 

“…Therefore, it can be ignited easier when burned in diesel engine. It has straight chain with OH group and has lower hydrophilic compared to methanol and ethanol [13][14]. High cetane number, good miscibility and higher heating value attract many researchers to consider n-butanol as an additive to biodiesel.…”

Biodiesel can be used as an alternative fuel for the diesel engine and have a good combustion characteristic because of their longchain hydrocarbon structure. However, biodiesel possesses few disadvantages such as lower heating value, higher viscosity, higher density and will contribute to several engine problems such as low atomization during injection and carbon deposit formation. There are many types of additives on the market but the extent of the additives on engine performance is unknown and only several researches has been done in studying the performance, emissions and fuel consumption of 100% palm oil methyl ester (B100 biodiesel). In this study, there is five type of B100 biodiesel. The objectives of this research are to identify individual composition in each biodiesel samples, such as the identification of additives and fatty acids methyl esters using gas chromatography (GC-FID). The experimental measurements of density, viscosity and calorific value of B100 biodiesel were conducted. The results showed that a blend of biodiesel with diethyl ether and n-butanol has the closest calorific value to fuel diesel followed by the combination additives of ethanol, butanol and methyl pyrrolidone. Engine performance and emission were also investigated by determining the BSFC, BTE and CO, HC, and NOx gas emissions by simulation using CONVERGE CFD software based on single-cylinder, direct injection YANMAR TF90 diesel engine parameters. Performance results show that the combination of diethyl ether and n-butanol as an additive with crude palm oil will give a higher brake power and lower NOx and brake specific fuel consumption among all samples. The emission studies revealed that the addition of n-butanol additive can reduce carbon monoxides (CO), nitrogen oxides (NOx), particulate matter (PM) emission while diethyl ether can improve the spray characteristics when it blends with B100 biodiesel due to its low density and viscosity.
