“…A similar observation was made in other studies [16,17]. Several investigations have correlated the presence of high oxygen content and large surface area of the biodiesel-derived soot to its higher rate of oxidation [18,19]. Furthermore, the effect of dilution of diesel with the addition of biodiesel and the relative significance of oxygen content has been statistically studied by some research groups [20].…”

Less viscous and low cetane (LVLC) fuels have emerged as the promising alternative fuels or additives to fossil fuels. Camphor oil is one such potential LVLC fuel currently under consideration. However, it's sooting propensity and subsequent effects on soot nanostructure, when blended with diesel, are not well understood. In this work, the effects of camphor and camphor oil addition to diesel on the sooting propensity, soot oxidative reactivity, and the chemical composition, structural disorders, and the morphology of soot particles are studied using a diffusion flame. The chemical and the microstructural changes in soot are investigated using several experimental techniques such as energy dispersive X-ray spectroscopy, high resolution transmission electron microscopy, Raman and electron energy loss spectroscopy, and powder X-ray diffraction, while the oxidative reactivity is studied using thermogravimetric analysis. The activation energy for O2-induced soot oxidation during the initiation stage shows a significant reduction in its value with the addition of camphor and camphor oil to diesel, which were 220 kJ/mol for diesel soot, 175 kJ/mol for 5% camphor/95% diesel soot, and 150 kJ/mol for 10% camphor oil/90% diesel soot. The blending of camphor and camphor oil with diesel results in soot with smaller fringe length and primary particle diameter, but increases the fringe tortuosity, the degree of crystal disorder, and the amounts of oxygen functionalities and aliphatics in soot. These physico-chemical changes in soot are used to explain the observed trend of oxidative reactivity. This study successfully demonstrates the potential of terpenoid keto compounds with characteristic bicyclic ring structure in improving 2 oxidative reactivity of combustion derived soots as desired in diesel particulate filter technologies.

“…First, biodiesel represents a strategic renewable energy source that can replace diesel oil; second, biodiesel may be useful for reducing the emission of greenhouse gases [1]. It has been established that the combustion of diesel oil by engines produces mixtures of anhydride pollutants (CO x , SO x and NO x ), solid particles and unburned hydrocarbons that generate multiple environmental and health problems and contribute to global warming and the formation of acid rain [2][3][4].…”

The increasing use of petrodiesel-biodiesel fuel blends throughout the world requires fast, economic and efficient analytical techniques that can be used for the quality control of these fuels. In this work, we developed an analytical method for determining the concentration of African palm biodiesel in blends with petrodiesel; the method is based on infrared spectroscopy (FTIR-ATR). To build a prediction model, nineteen petrodiesel-biodiesel blends were prepared in triplicate with biodiesel concentrations for 0%-100% by weight. The blends were analyzed using Fourier transform infrared spectroscopy, the spectral fingerprint data were used to build a prediction model through PLS regression. The optimal number of principal components (PCs), the standard error of calibration (SEC), the standard validation error (SEV), the correlation coefficient of calibration (r Cal) and the validation correlation coefficient (r Val) were used to validate the predictive ability of the model. The results show that the model obtained in this work has a good ability for determining the concentration of African palm biodiesel in petrodiesel-biodiesel blends.

“…As one kind of renewable alternative fuels, ethanol could be produced by alcoholic fermentation of sugar from vegetable materials, such as corn, sugar cane, sugar beets, or agricultural residues [4]. There are many utilizations of ethanol in diesel engine [6,7], and the most convenient method of employing ethanol in the diesel engine is blending ethanol and diesel with a solubilizer to form uniform and stability blend fuels.

This paper describes the simulated study on atomization, wall-film formation, combustion and emission forming process of ethanol-diesel blend fuels in a high speed light duty diesel engine. The result shows that increased ethanol volume percentage of the blend fuels could improve atomization and reduce wall-film formation. However, in the meanwhile, with the increased ethanol volume percentage, low heat values of blend fuels decrease, while both total heat releases and cylinder pressures drop. By adding codes into the FIRE software, the NOx and soot formation region mass fractions are outputted. The simulated results display a good correlation with the NOx and soot formation. Besides, the NOx, soot and CO emissions decrease with the increased ethanol volume percentage. The power output of engine penalize, while energy utilization of blend fuels improve and combustion noise reduce, owing to the increased ethanol volume percentage
