“…Fig.3. Interaction of the fuel spray with the combustion chamber wall [29] Mechanism of decay of fuel spray: secondary decay plays a decisive role in the formation of fuel liquid film on the wall surface because it governs the ability to separate fuel particles from the spray [22]. The secondary decay process occurs when the surface tension of the fuel droplet is small, affecting the resistance to the deformation of the fuel droplet.…”

One of the important researches on fuel use in diesel engines is the basic study of deposits formation in engine combustion chambers. The process of creating deposits in the engine combustion chamber is a complex phenomenon causing many different problems. Therefore, it is necessary to study the mechanism of deposits formation and development in engine combustion chamber when using traditional diesel or biodiesel. The study of combustion chamber deposits in internal engines was conducted to understand the effects of deposits on the engine and how they were formed and developed. Most of the current studies on deposits are carried out using statistical results from vehicle's engines. Testing on real engines requires a long time and long distance travel, which makes the cost of both tests very high, causes damage to the engine during deposits testing. Studying and finding a simpler, more cost-effective experimental model that meets the requirements of the deposits formation testing and assessing the factors that make up them are essential. An experimental model design to determine the formation mechanism of deposits in the combustion chamber is the key point of the paper. This study clarifies the deposits formation of fuel in the engine by using a method called a heated surfaces deposits formation testing (HSDFT) and simulate the accumulation and development of deposits in combustion chamber. This model will help researchers to initially build the database effectively to determine the deposits formation mechanism in the combustion chamber of diesel engines when using different fuel.

“…The storage stability of biodiesel was studied since 1985, exposure to heat and air greatly accelerated degradation of biodiesel, but when stored at 20 °C in closed containers or stored after the addition of an antioxidant, the biodiesel remained stable. Furthermore, researcher monitored the production of acids, peroxides, and aldehydes, as well as increase in viscosity induction storage time over a period of 90 days [5][6][7][8][9]. It found that the stability of biodiesel for 180 days of storage showed that exposure to metals also increased the rate of degradation and exposure to higher temperatures in pro-oxidizing conditions accelerated loss of stability [10][11][12][13][14][15].…”

In recent years, there was a major drawback in the reduction of fossil fuels. Researchers attempts to find solutions to overcome this crisis including using biodiesel as replacement for fossil fuel. The aim of this study is to investigate the effects of ambient and storage characteristics on flash point and water content of biodiesel derived from crude palm oil, jatropha and waste cooking oil. There are three types of biodiesel blending which is 5 vol %, 10 vol % g and 15 vol% blending and compare with commercial diesel. There are three type of biodiesel blended from Crude Palm Oil, Jatropha, and Waste Cooking Oil. The biodiesel samples were stored in clinical compartment, at different temperatures and were monitored at regular interval over a period of 1960 hours’ periods and storage temperature from 28oC~35oC. The analysis of blending biodiesel properties is performed with ASTM D6751 and EN 14214 standard. The changes of properties of biodiesel such as density, kinematics viscosity, acid value, water content and flash point of biodiesel were discussed in detail. High blending ratio CPO blends and longer storage period influences the increasing of viscosity for both conditions. Storage characteristics has a great influence on the biodiesel blends especially under high blending ratio. Increasing storage duration and temperature for all variant blending ratios are found to influences the increasing of the water content fuel density, resulting in increased the biodiesel viscosity. However, flash point of all biodiesel blends tends to decrease with increasing storage duration at different storage temperature.

“…Because of these reasons, two strategies such as finding the renewable energy sources [3] and technical solutions for emission management for the improvement of the effectiveness in the use of energy and the environmental protection are essential [4]. Among emissions emitted into the air from the fossil fuel combustion of diesel engines, sulfur emission (SOx) is a dangerous pollutant and it is complicated to control [5], [6]. In the exhaust line of engines, SOx reacts to water under the appropriate conditions to form sulphuric acid, resulting in negative impacts on materials (corrosion) and environment (acid rain).…”

Pollution in the maritime field is considered as such a serious problem that scientists, policymakers, and managers are always urged with a desire to find solutions and strategies one way or another to minimize its negative impacts on the environment and the life. Among the effective solutions, the use of fuels with limited-sulfur content or bio-based fuels has been paid much attention to due to their advantages in the use of marine diesel engines. In the current study, a type of fossil diesel fuel with ultra-low sulfur content (ULSD) was mixed with coconut oil (CO) through the ultrasonic treatment under the changes in volume fraction of as-used fuels, the correlation on viscosity selected the rate mixing between ULSD and coconut oil. After 12 minutes of ultrasound treatment, the highest stability of the ULSD-CO emulsion was achieved correspondingly to 97.8% for a mixing rate of 76%(ULSD):24%(CO) along with the distance of 85mm from the containing-vessel bottom to the ultrasound horn tip. Moreover, the spray characteristics including penetration length and a cone angle of ULSD, CO, and ULSD-CO emulsion were also examined and compared to diesel fuel. The similarity of spray characteristics to diesel fuel, containing ultra-low sulfur content and oxygen content, renewability are considered as some advantages of ULSD-CO emulsion as used for diesel engines aiming to meet the stricter requirements of IMO regulations about the strategies of environmental protection.
