Abstract

Naphthalene is a chemical hydrocarbon compound with the chemical formula C10H16O. Napthalene is a simple polycyclic aromatic hydrocarbon compound, in the form of a white crystalline solid with a characteristic odor and detectable by the sense of smell at concentrations as low as 0.08 ppm. As an aromatic compound, napthalene's structure consists of a pair of linked arene groups or benzene rings. Objective: To determine the ratio of the power produced by a gasoline engine using a mixture of naphthalene with 90 fuel compared to the use of pure fuel in the engine. Knowing the effect of exhaust emissions produced by gasoline engines using 90 octane fuel, with a mixture of naphthalene and without a mixture of naphthalene. The method used in this study was experimental, tested only with pertalite fuel, Pertamax and added camphor (Napthalene) consisting of 5gr, 10gr, 15gr with 2lt volume of 90 octane fuel fuel. The conclusion is expected that the addition of napthalene has an effect on power and exhaust emissions.

Abstract

Along with technological developments, the system in vehicle engines is also experiencing developments, with the technology embedded in vehicle engines it is hoped that vehicles can become more efficient, powerful, produce low emissions, even vibration and sound produced is very small. This also needs to be supported by using the right fuel. Bioethanol is an alternative fuel made from vegetable and can produce complete combustion. The data collection method is by recording the proportion of the bioethanol mixture with 92 octane fuel and changes in engine speed, when vibrations occur, the LCD vibration meter will display the vibration value. Engine speed starts from 1500 to 8500rpm with a change of 1000rpm each rotation. From the tests carried out, at engine speed of 1500 to 2500 rpm the 5% mixture is a good mixture because the vibration value is lower than before mixing. Then for engine speed of 3500 to 8500 rpm a 10% mixture is a good mixture because the vibration value is lower than before mixing and lower than other mixtures.

Abstract

Cases of vehicle tank leaks throughout 2024-2025 amounted to 23,500 units. The cause of vehicle tank leaks is water vapor (condensation) because the empty space in the tank contains air. Water Level Sensor is a sensor used to detect and measure water levels. The way the Water Level Sensor works by utilizing an open conductor path that is connected when in contact with water, the Water Level Sensor used is HW 37 and HW 38. The purpose of this study is to determine the effect of the type of Water Level Sensor HW 37 and HW 38, variations in working voltage of 3V and 5V and to compare the percentage error value of water level measurements of 5, 10, 15 and 20 mm. The test method uses experiments presented in the form of tables and graphs. The independent variables are the type of sensor and voltage. The dependent variables are the accuracy of water level measurements of 5, 10, 15, and 20 mm. The test results of the Water Level Sensor HW 37 with the best accuracy occurred at a voltage of 5V with a percentage error value of 0.35%, while the Water Level Sensor HW 3 with the best accuracy occurred at a voltage of 5V with a percentage error value of 0.10%.
