“…Thus, researchers, engine makers, and designers are interested in the evaporation of liquid fuel droplets impinging on heated surfaces. The interest in this subject has been simulated by several researchers via the heated wall surface method in the early studies on the evaporation characteristics of fuel droplets [21][22][23][24][25]. The rate at which fuel evaporates on various hot surfaces, such as the combustion chamber, affects exhaust emissions, including PM and NOx, and its efficiency in compression ignition engines [25].…”

The purpose of this study is to investigate the evaporation characteristics of different types of fuels by applying the hot surface deposition test (HSDT). Generally, HSDT method is a simplified method to simulate fuel deposition in diesel engines. In this study, diesel fuel (DF) and palm oil biodiesel with different blend ratios (B10-B50) were used to evaluate the fuel droplet evaporation behavior on a heated aluminum alloy plate surface. Single fuel droplet was impinged on the heated plate at various surface temperatures (Ts). Important data from the evaporation characteristics was the maximum evaporation point (MEP), which is the temperature point where a droplet evaporates in the shortest lifetime (tlife). MEP is referred to identify the surface temperature range in which fewer deposits will be produced by the test fuel. Furthermore, MEP is also used to determine the appropriate droplet interval to create wet and dry conditions in the fuel deposition test. The obtained MEP was 360°C (DF), 365°C (B10, B50), 375°C (B20, B40), and 385°C (B30).

“…High viscosity and density lead to poor atomization, time-consuming breakup and mixture formation, increased carbon deposition, and a high energy demand for pumping fuel (Aliyah et al, 2016). Until now, some techniques, such as blending, preheating, and emulsification, have been applied to improve the above-mentioned disadvantages of biodiesel (Suryantoro et al, 2016;.…”

Biodiesel has been considered as the potential fuel type with many advantages such as environmental pollution reduction, no sulfur production, and biodegradation. However, disadvantages of biodiesel such as high viscosity and high density affected diesel engines and fuel systems negatively. Thus, it is necessary to reduce the viscosity and density of biodiesel fuel in unmodified diesel engines. Until now, a large number of empirical correlations have been used to predict the viscosity and density of biodiesel-fossil diesel fuel blend This study was conducted to predict the kinematic viscosity and density of blends of biodiesel and fossil diesel fuel. Three types of biodiesel were examined: Coconut oil-based biodiesel (COB), Jatropha oil-based biodiesel (JOB), and Waste oil-based biodiesel (WOB). Twenty-four samples of the three types of biodiesel-diesel fuel blends were created by blending 5% (B5), 10% (B10), 20% (B20), 40% (B40), 50% (B50), 60% (B60), 75% (B75), and 100% (B100) of biodiesel with conventional diesel fuel to produce the corresponding blends for experimental purposes. Experimental correlations and mathematical equations for predicting the relationship between the kinematic viscosity and the density of the biodiesel-fossil diesel fuel blends, the dependence of the kinematic viscosity and the density of the biodiesel-fossil diesel fuel blends on biodiesel fractions, and the effects of temperature on the kinematic viscosity and density of pure biodiesel were developed. The results of the experimental correlation data were near the predicted mathematical equation with a confidence level of 95%.

“…To solve this challenge, further research with a focus on fuel characteristics and the ability of deposit formation in engine parts is required. It should be noted that research on the formation of deposits in combustion chambers and injectors basically includes measurement of deposit thickness in engine components in response to the application of test and reference fuels [10,11]. The purpose of this research is to analyze the effect of hydrotreating in biodiesel (HVO) on the growth of deposits in biodiesel.…”

The usage of biodiesel has been encouraged by government based on the issuance of The Regulation of Minister of Energy and Mineral Resources No. 12/2015 on the supply, utilization, and administration of biofuels as other alternative fuels. This regulation sets mandatory biodiesel mixture by 30 percent for national energy consumption by 2025. But the usage of biodiesel with a larger percentage in diesel engines still leaves some problems with the decline of biodiesel fuel quality and the formation of deposits in combustion chamber and injectors. The purpose of this study is to compare biodiesel fuel (B20) with Hydrotreated Biodiesel (HBD) in an experiment by using fuel droplet method on a plate to observe the characteristics and mechanism of deposit formation. Plates are heated in few temperature variations in a sealed test rig so that the conditions are similar to the engine real conditions. Deposit growth of Hydrotreated Biodiesel as known as Hydrotreated Vegetable Oil (HVO) less better than Fatty Acid Methyl Ester (FAME). It may occurred because the lubricity of HVO is very low due to the absence of sulfur and oxygen compounds in the fuel, that causes oxidation that can lead to deposits in the combustion chamber..
