“…As expressed before, flash point will be estimated using these two properties. Therefore, in this section the focus will be on an exhaustive review of flash point experimental data of biodiesel/diesel blends from edible [25-27, 30, 38-67] and non-edible oils [9,25,49,50,52,53,[59][60][61][62][68][69][70][71][72][73][74][75][76][77][78][79][80][81][82][83][84][85].…”

This paper presents characterization studies of flash point, kinematic viscosity and refractive index for several biodiesel/ diesel blends. Biodiesel is produced from soybean, corn, olive, canola, almond, grape and peanut oils. Regression equations are presented to estimate the kinematic viscosity, refractive index and flash point of the studied biodiesel and their blends with diesel fossil fuel as a function of the blend composition. Moreover, as viscosity and refractive index measurements are simple, fast and require very small volume of samples, a correlation study for the blends is conducted to estimate the flash point from these two properties. It is shown that when kinematic viscosity and refractive index are both used for the estimation of the blends flash point, the R 2 values are higher than those found using simple correlations.

“…In that study, it was said that the NOx generation of biodiesel blends was complex and not conclusive and there were many factors that can influence NOx emissions such as fuel cetane number, density, volatility, degree of unsaturation, the chemically bound oxygen content, equivalent ratio or aromatic fuel composition. Mangus et al [60] used four biodiesels (palm, jatropha, soybean, beef tallow) and its blends (0%, 5%, 10%, 20%, 50%, and 100% by volume) to compare the emission characteristics of NOx after application to diesel engines. In this study, NOx decreased with increasing the biodiesel blend rate.…”

This paper presents the combustion and emissions characteristics including volatile organic compound (VOC) of a common rail direct injection diesel engine fueled with palm oil biodiesel blends contained 0%, 10%, 30%, and 100% (by volume) biodiesel at low idle speed, i.e., 750 rpm. The nitrogen oxide (NOx) emissions of biodiesel blends were lower than that of pure diesel and NOx tended to decrease as the blending ratio increased. Soot opacity and hydrocarbon (HC) were reduced with an increasing blend ratio. Carbon monoxide (CO) varied with the engine load conditions. Under low load, CO emissions tended to decrease with increasing blending ratio and increased under high load. Alkane and aromatic VOCs were mostly emitted. Benzene and tetrahydrofuran accounted for the largest percentage of total detected VOCs in all test conditions. Benzene, toluene, ethylbenzene, xylene (BTEX, toxic aromatic VOCs) were detected for all tests. Among BTEX, benzene has the highest emission ratio, followed by xylene, toluene, and ethylbenzene. Benzene increased for all tests. At low engine load, toluene, ethylbenzene, and xylene decreased with increasing blend ratio. However, these increased at high engine load. When pure palm oil biodiesel was applied at high engine load, benzene decreased.

“…Compliance with new regulations on sulfur content in fuels used by ships, when operating in emissions control areas, can be made using a fuel with a sulfur content of 0.1% always of the vessel's operation or switching from a high sulfur fuel to a 0.1% sulfur fuel when the vessel enters the emission control area. Several studies have shown that fuel conversion during ships' operation could have several problems related to the properties of the fuel such as viscosity, lubricity, flash point, ignition, and combustion quality ) (Mangus et al (2015)). Regulations around the world are beginning to require the use of ultra-low sulfur fuels.…”

As a rule, the highest permissible sulfur content in the marine fuel must drop below 0.5% from 1 January 2020 for global fleets. As such, ships operating in emission control areas must use low sulfur or non-sulfur fuel to limit sulfur emissions as a source of acid rain. However, that fact has revealed two challenges for the operating fleet: the very high cost of ultra-low sulfur diesel (ULSD) and the installation of the fuel conversion system and the ULSD cooling system. Therefore, a solution that blends ULSD and biodiesel (BO) into a homogeneous fuel with properties equivalent to that of mineral fuels is considered to be significantly effective. In the current work, an advanced ultrasonic energy blending technology has been applied to assist in the production of homogeneous ULSD-BO blends (ULSD, B10, B20, B30, and B50 with blends of coconut oil methyl ester with ULSD of 10%, 20%, 30% and 50% by volume) which is supplied to a small marine diesel engine on a dynamo test bench to evaluate the power and torque characteristics, also to consider the effect of BO fuel on specific fuel consumption exhaust gas temperature and brake thermal efficiency. The use of the ultrasonic mixing system has yielded impressive results for the homogeneous blend of ULSD and BO, which has contributed to improved combustion quality and thermal efficiency. The results have shown that the power, torque, and the exhaust gas temperature, decrease by approximately 9%, 2%, and 4% respectively with regarding the increase of the blended biodiesel rate while the specific fuel consumption and brake thermal efficiency tends to increase of around 6% and 11% with those blending ratios.
