Abstract

In this modern era, technological developments are growing so fast, from information technology, communication technology, transportation, medical to industrial technology. One of the advances in the rapidly developing industrial world is the technique of coating metal or material surfaces. There are many methods of material surface coating techniques such as Physical Vapor Deposition (PVD), implantation, radio frequency (RF) sputtering, chemical vapor deposition, polymer supported electrodes (PSE), and electrochemical deposition. The Electrochemical Deposition method is a simple method with cost advantages, but this method requires processing of liquid waste which has recently become a public concern regarding environmental pollution. The APD (Arc Plasma Deposition) method has a higher level of satisfaction in fulfilling the requirements for deposition of a material, namely it is easy to control the size of the particles to be deposited and is faster in the deposition process and also has a very small impact on environmental pollution. This method requires quite large assets for its application so not many people know the stages of layer deposition. Therefore, the preparation of a prototype of a laboratory scale thin film growth machine was carried out and can carry out the deposition of a material onto a material. To optimize the layer growth results, adjustments are required in the machine parameter settings and the pure gas rate used

Abstract

Lubricating oil was type of fluid needed by a machine to work. Significant changes in the temperature of the lubricating oil viscosity up to low level made the engine components less lubricated. It caused the engine components to heat up quickly due to the friction between the metals that became greater. Poor quality lubricant could cause deposits to appear in the engine room which resulted in the engine working harder. The purpose of this study was to investigate the effect of the use of cooking oil added with surfactants of estolides and diglycerides with percentages (2.5%, 5%, and 7.5%) as engine lubricants on engine temperature and power produced by motor vehicles. The research method used was an experiment on a 125cc gasoline motorcycle lubricant with standard conditions. The data taken in this study included engine temperature and power. The results showed that with cooking oil mixed with 7.5% estolides surfactants after heating produced power with an average value of 6.52 HP and a mixture of 5% diglyceride surfactant producing an average value of 5.87 HP, which had a higher average value compared to oil rated at 5.37 HP. When using 2.5% estolides, the lowest value was 83.67°C and using a diglyceride percentage of 7.5% produced the highest value, namely 107.03°C. The use of cooking oil had an influence on engine temperature and power. The average power value of 5.71 HP was higher than oil with a value of 5.37 HP. The engine temperature value using cooking oil was 92.7°C lower than oil with a value of 96.63°C

Abstract

One of the efforts to improve the performance of a gasoline motor with a 2-stroke system is to make some modifications to the combustion system components. By changing the volume of the induction tube and the thickness of the membrane the performance of a 2-stroke gasoline motor can be improved from standard conditions. The purpose of this study is to understand how changes in the volume of the induction tube affect the performance of a 2-stroke motor engine with a capacity of 150 cc, with the aim of restoring optimal performance to the motor. This study uses an experimental method on how the effect of variations in induction tube volume and membrane thickness on gasoline motor performance. The test variable in the study is to compare 3 induction tube volumes and 2 membrane thicknesses to the resulting engine performance. Tests were carried out on a 150cc 2-stroke gasoline motor using a chassis dynamometer as a tool to see the performance of the test engine and a gas analyzer as a tool to measure the level of exhaust emissions produced. From the tests that have been carried out, it shows that the volume of the induction tube and the thickness of the membrane have an influence on the performance of a 150 cc 2-stroke gasoline motor. The highest torque is obtained on a 300cc induction tube with a membrane thickness of 0.45 mm of 19.60 Nm at 9,000 rpm. While for fuel consumption using the calculation of specific fuel consumption (SFC) obtained results of 0.08 g / kW.h. for exhaust emissions on HC produced at 2452 ppm and 0.97% on CO gas.

Abstract

The development of technology in motor vehicles, especially in improving engine performance, is increasingly developing. One of the technological developments is water methanol injection or often abbreviated as WMI, which is injecting water with methanol into the engine combustion chamber through the intake manifold. Methanol can be used by mixing it with fuel or used alone (pure methanol) and is able to produce more heat than fuel. High-quality fuel certainly comes with a high price tag. For that reason, cetane booster is one of the innovations to improve fuel quality. The purpose of this study was to determine the effect of Water Methanol Injection on power and torque in Diesel Engines. In addition, this study also analyzed the interaction of the WMI mixture with the addition of cetane booster. Testing was conducted using a four-wheeled motor vehicle with an Elf Long 2771 CC engine type, using Solar B30 fuel, with three variations of WMI percentage, namely 10%, 30%, and 50%, without cetane booster and with booster. Testing was carried out at 1500 to 2500 rpm with an increase of 500 rpm using a dyno test tool. Data processing was performed using Two-Way ANOVA, commonly known as 2-way ANOVA. The tests conducted were power and torque tests. The study results showed maximum results at 2500 rpm rotation power at a WMI percentage of 30% with the addition of 150ml booster, reaching 77.19 Hp and a torque of 234.43 Nm. Therefore, it can be concluded that the use of a mixture of methanol and water has increased power and torque, although not significantly, while the addition of a 150ml booster has a major influence on the results of the power and torque tests.
