NOx as one of the exhaust emissions is harmful to human health. Many methods can reduce NOx emissions, one of them is water in fuel emulsion. By using experiment, research has been conducted in surfactant selection. The results of experiment show 4 surfactant, which is best used to the diesel engine is tween 80 and span 80. This experiment needs some water contents variation emulsifier with 10%, 15%, and 20%. In this different variation of water is very influential on performance and NOx emissions. By using water fuel emulsion of 10% in SFOC has been increase 216,2 g/Kwh or 11.6% compared to Pertamina Dex of fuel. However, the water used in fuel emulsion of 15% and 20% in SFOC increased to compare 10% emulsion. The effect of water use in fuel emulsion has been reduce NOx emission. Water in fuel emulsion has been decrease 50.5%. Generally, the emission level of a diesel engine that using water in fuel emulsion has been improved until entering on Tier 3 specification of IMO rules

The main function of cooling system is to control the temperature in the engine. To know the flow in the jacket cooling system for marine diesel engine 93 KW and the couple simulation between 1D modeling and 3D modeling, the methodology used. The analysis process was performed by using 3 diffrent softwares. The methodology to analysis fluid flow is CFD (computational fluid dynamic) with steps were problem identification, literature study, design the jacket cooling system based on the cummin diesel engine 93 KW, 1D modeling of cooling system, 3D modeling fluid flow in jacket cooling system, and conclusion. The input of 3D jacket cooling simulation are mass flow, fluid temperature, wall temperature, and heat transfer. The result from this bachelor thesis is fluid flow in jacket cooling system and another parameter output such as temperature flow and velocity if fluid in the jacket cooling system. The result of the flow in jacket cooling is much turbulance in various are of jacket cooling its mean the jacket cooling have a good enfficiency of heat transfer, and the fluid temperature show the increasing temperature from inlet to outlet because of heat transfer happen in the jacket cooling between wall of jacket cooling and fluid. The engine speed will affect the cooling system, if the engine speed is increasing, the speed of flow will increase because the cylinder block need more coolant and the temperature of cylinder block will increase

The Effect of Using Various Magnetic Materials on Diesel Engines using Biodiesel Fuel Aguk Zuhdi Muhammad Fathallah; Adhi Iswantoro; Hafiz N. H. Perdana

One of method to improve engine performance and reduce fuel consumption is to use exposure to magnetic fields in the fuel lines. Several studies have proven that magnetic field exposure can improve diesel engine performance. This research aims to test the performance of a diesel engine using fuels that are given a magnetic field from 3 types of permanent magnets, namely magnets made from Neodymium Iron Boron (NdFeB), Aluminum Nickel Cobalt (AlNiCo), and Ferrite (Fe). Performance tests on the Yanmar TF85MH diesel engine include power and torque. The fuel used in this research is Biodiesel B20. The results showed that neodymium magnets (NdFeB) are the best magnets of the 3 types of magnets tested with an average increase in power of 2.30%, an average increase in torque of 2.35%.

Previous research on biodiesel properties, based on the 2015 Indonesian National Standard (SNI), limited its characteristics to testing. Therefore, the author conducted further research on the performance and durability of single-cylinder, four-stroke diesel engine components. This led to the future use of B100 biodiesel as an alternative fuel if commercially produced. The fuel used is B100 biodiesel and biodiesel plus G57 additive. G57 additive or D.04.BXD catalyst, which can achieve low emissions, high quality, high fuel performance, and high efficiency (PT. SEGARA, 2022). The results of the 200-hour durability test revealed no changes in wear related to piston gap and groove size, or the visual condition of the main bearing. The performance results obtained by Biodiesel B100 obtained an average engine power of 0.99 Hp, an average torque of 3.5 nm, SFOC by producing an average of 798.47 Gr / kWh better than Biodiesel B100 + G57 at high idle speed the engine power obtained was an average of 0.97 Hp, torque with an average of 3.4 nm, SFOC obtained an average of 817.34 Gr / kWh, at max torque speed Biodiesel B100 + G57 obtained an average engine power of 2.93 Hp, torque with an average of 13.03 nm, SFOC produced an average of 392.08 Gr / kWh better than biodiesel B100 which obtained an average engine power of 2.84 Hp, an average torque value of 12.56 nm, The average SFOC value is 473.04 Gr/kWH and B100+G57 biodiesel at rated rpm speed obtained an average engine power of 4.6 Hp, an average torque of 15.08 nm, an average SFOC of 375.40 Gr/kWH much better than B100 biodiesel which obtained an average engine power of 4.1 Hp, an average torque of 13.57 nm, an average SFOC of 451.54 Gr/kWH. Lab test results of B100+G57 biodiesel content have a flash point of 164 °C compared to B100 which obtained a greater result of 168 °C. The water content in B100 biodiesel is 0.118% smaller than the water content in B100+addictive G57 biodiesel of 0.127%. The density of B100 biodiesel is 0.880 g/cm3, slightly higher than that of B100+G57 biodiesel, which is 0.879 g/cm3. The viscosity of B100 biodiesel is 8.05 cSt, while B100+G57 biodiesel has a viscosity of 7.67 cSt.
