Abstract

The use of fossil diesel fuels still produces carbon dioxide emissions (CO2), sulphur dioxide (SO2), hydrocarbon emissions (HC), nitrogen oxide (NOx), and high total particles and carbon monoxide (CO). Moreover, the need for transportation of motor vehicles will always increase every year. The emission of exhaust gases resulting from the combustion process can essentially be reduced by improving fuel quality, the homogeneity of the fuel mixture, and regulating proper combustion. There are several ways to reduce exhaust emissions from diesel engines by providing precise injection pressures. This is done to get the perfect combustion. In addition, improving fuel quality is a way to reduce emissions of exhaust gases. Another one is by adding methanol to the diesel. The addition of methanol can reduce the emission of exhaust gas produced. The process of mixing the solar and methanol takes the addition of surfactants to obtain good homogeneity. Testing was conducted using simulation software with engine modeling. The result can be seen in the reduction and the addition of standard pressure 200 bar, that the emulsion fuel in SFOC (specific fuel oil consumption) suffered a decrease and increased by 0.2% and 0.3% at pressure 160 bar and pressure 240 bar. The fuel solution on SFOC suffered a decrease and an increase of 0.3% and 0.25% was produced by pressure 160 bar and pressure 240 bar. The highest NOx is produced by 240 bar injection pressures with Dexlite fuel while the lowest NOx is produced by 160 bar injection pressure with emulsion fuel.

Abstract

Environmental needs to reduce pollution caused by used lubricants from mineral oil encourage the development of biolubricant. One of the biolubricant raw materials from plants available in the environment is the castor plant (ricinus communis). The biggest composition in castor oil is ricinoleic acid which can be used in the manufacture of biolubricants. The purpose of this study was to study the physical properties of biolubricants from castor oil, to compare the properties of biolubricants and mineral lubricants after conducting a diesel engines durability test, and comparing performance between both lubricants during durability test. Experiment were carried out on the Dongfeng R180 diesel engine using Pertamina Dexlite fuel and mineral oil Pertamina Mesran B SAE 40 as a comparison. The results of biolubricant properties test (kinematic viscosity, viscosity index, pour point, flash point, and total alkali number) were obtained according to the flash point value not fulfilling the Minister of Energy and Mineral Resources Regulation regarding standard. From properties between biolubricants and mineral lubricants after a 200-hour endurance test there is properties change in both lubricants. Increase the value of viscosity, total number of base, and flash point because it contains water in the biolubricant causing oxidation. The iron content of the biolubricants after the endurance test is greater than mineral lubricants. However, the aluminum content in biolubricants is smaller when compared to biolubricants. From the performance test obtained SFOC which is produced when using mineral oil at peak torque is 3.1% lower than compared when using biolubricants. The average SFOC in the value condition when using biolubricants is 2.3% lower than using biolubricants. The average power when using mineral lubricants is 0.72% lower when compared to biolubricants and the resulting torque is 0.23% lower when compared to using biolubricants.

Abstract

The Indonesian government's policy of using biodiesel as an alternative fuel in the shipping industry is still an intensive discussion. Biodiesel as a substitute for diesel fuel has an impact on engine performance, lifetime and emission. The use of biodiesel fuel will increase the wear rate on metal components in diesel engines. From a series of tests carried out in accordance with Engine Manufacturer Association (EMA) standards, wearing on several engine components would be increase when the engine run using biodiesel palm oil (B30). The results showed that there was 19.8% aluminum content, 0.75% iron content, and chromium content in diesel engine lubricating oil with B30 biodiesel fuel higher than using diesel fuel. In addition, the clerance in the pisthon ring also increases and wear is seen on the journal bearing. However, the deposits formation in the diesel engine components made from palm oil biodiesel B30 is 5.43% increase than diesel fuel. From these results, it may be concluded that using of B30 palm oil biodiesel as fuel reduce durability of diesel engine standart.

Abstract

The application of a dual-fuel engine has massively been used as the main engine. However, in dual-fuel engine operations, problems occur in low-load operations. The combustion quality with unstable combustion conditions and relatively low thermal efficiency. In this research, a gas split injection strategy was implemented on the dual-fuel engine. The purpose of this research is to compare the performance of the engine between dual-fuel operations using gas split injection strategy and single injection. Furthermore, split injection is a fuel injection system by dividing the injection into several injection stages with a certain mass and period. This injection system was applied on a dual-fuel engine system, which was previously a modification of the conventional diesel Yanmar TF 85 MH. The variation in this study is the injection split ratio (ISR) 75-25, variations in injection time, and variations in load with specified engine speed at 2000 RPM. The results obtained in this study are the best variations found in ISR 75-25 gas split injection with injection distance at 260°bTDC & 244°bTDC. Due to the injection distance, a significant difference occurred in all parameters tested between single injection and split injection. The significance of the difference in power, torque, BMEP, SFOC, and the thermal efficiency only occurs at 100% load, which is 4.3%; 4.2%; 4.2%; 16%; 18.3%.

Abstract

One of the alternative and renewable energies is green diesel. Despite the fact that both use the same raw material, vegetable oil, the processes for producing green diesel and biodiesel are somewhat different. Green diesel is generated via the hydrotreating process, which involves injecting hydrogen gas into an oil to remove oxygen. The combustion process in the engine is influenced by the nature of the fuel. Green diesel fuel has a higher yield of material than biodiesel fuel. High pressure caused by combustion in the engine combustion chamber affects the vibrations and noises of diesel engines. By varying engine speed and load, this study compares noise and vibration produced by green diesel fuel to biodiesel B30 using a simulation process. The results showed that green diesel fuel produces more noise and vibration than biodiesel B30 fuel and that this is directly proportional to the pressure and power produced in the combustion chamber by the green diesel fuel combustion process. As the pressure in the combustion chamber rises, the explosion becomes more powerful, resulting in increased diesel engine noise and vibration.

Abstract

Piston is one of the important parts in the combustion process in a diesel engine, it consists of two namely the piston head and connecting rod, where the piston head consists of three parts, namely the piston crown, piston rings, and piston pins. This paper wants to prove which is more effective in modifying the TCC piston crown shape on a four-Stroke one-cylinder diesel engine fueled with B-30 in terms of noise. To measure noise, several experiments were carried out. One way is to use an application that can help make measurement easier is to use the simulation. The Simulation can measure the level of noise by using the tools in an application the same as in reality. The piston area is very influential on the combustion process, with the greater piston area, the resulting explosion is greater which results in and produces a high pressure also it is directly proportional to the noise level. After everything is measured, then we compare it with the engine's performance and give maximum results between the level of noise with engine performance. The result is using a piston case 4 (+1) which has a larger area experiencing the highest noise level using B30 Diesel Fuel or High-Speed Diesel (HSD) Fuel. Under load conditions, with a 50% load, the noise level on piston +1 (Case 4) experiences the highest noise level using B30 Diesel Fuel or High-Speed Diesel (HSD) Fuel.

Abstract

This alternative research fuels in the form of biodiesel from waste cooking oil. In addition, the purpose of this study is to determine the effect of waste cooking oil biodiesel blends in the performance testing of a one-cylinder diesel engine simulation modeling. The method used by the author in this study is to use a simulation method. Performance-based diesel motor performance tests are performed using HSD, and also with variations of used cooking oil biodiesel fuel mixtures. From the performance test results at full load, it was found that the comparison of the value of the power mix of biodiesel waste cooking oil with HSD decreased power. At B50 decreased power (6.38%), B60 (7.6%), B70 (8.9%), B80 (10.2%), B90 (11.4%), and B100 (12.7%) at maximum RPM. The torque value obtained in the biodiesel fuel mixture also decreased compared to HSD in the same cycle. The lowest SFOC value is produced by HSD fuel. SFOC HSD value is lower than cooking oil biodiesel mixture which is higher (6.8%) B50 fuel, up (8.3%) B60, up (9.83%) B70, up (11.4%) B80, up (12.9%) B90, and up (14.5%) B100 at full load and maximum RPM conditions.

Abstract

According to Bank Indonesia, the current account deficit of Indonesia. In the second quarter of 2018 increased to USD 8.0 billion. One of the government's programs to reduce the current account deficit is by implementing a B20 biodiesel policy. The increasing percentage of biodiesel in fuel blends tends to decrease the quality of spray atomization, where it indicated by longer droplet breakup, spray penetration, droplet lifetime, and bigger droplet diameter. Higher viscosity causes a decrease in the quality of the spray from the injector. Previous research shows that the inlet temperature of the fuel can make the performance of small diesel engines slightly better. The research was conducted using petrodiesel and biodiesel fuel by varying inlet temperature of 50oC and 70oC. Based on that this research is conducted to understand the effect of fuel heating diesel engine combustion process. The result shows that generally maximum pressure is increased for every increase in fuel temperature. The heat release shows a decreasing trend for every increase in fuel temperature. Knock detection shows that generally when the fuel temperature increased the knocking is also increased. The increasing fuel temperature shows little effect on ignition delay except for the higher temperature of 60oC and 70oC where the ignition delay is the lowest and closest to that of a dexlite fuel.

Abstract

Alternative fuels for diesel engines have attracted the world's attention as an impact of the world energy crisis. For this reason, alternative fuel is needed to reduce the need for fossil fuels. Biodiesel fuel with the raw material of palm oil is the once alternative fuel to replace diesel fuel. This is because Indonesia is the largest producer of crude palm oil (CPO) in the world. But, the use of vegetable oil biodiesel can affect losses to engine lifetime. It can increasing metal wear rates in diesel engines. The experiment carried out by running diesel engines for 200 hours with Engine Manufacturer’s Association (EMA) standard. B30 palm oil biodiesel affected the wear metal contact in diesel engines. Aluminum content in used lubricating oil fueled by B30 palm oil biodiesel is 19.8% greater, iron content 0.75% greater, and chromium content greater than metal content in used lubricating oil fueled by diesel fuel. In addition, the use of B30 palm oil biodiesel causes a larger piston ring gap and worse condition on journal bearing. But, deposit forming in the diesel engine components fueled by B30 palm oil biodiesel is 4.27% lower than diesel fuel. It can be concluded that the use of B30 palm oil biodiesel causes greater metal wear than the use of diesel fuel.
