Abstract

This research proposes a fuel system conversion from a carburetor to an electronic fuel injection (EFI), to save fossil fuels using gasoline-ethanol combined with water injection. Beneficial as an offer for Indonesian motorcycle environmental friendliness in terms of exhaust emissions. The goal of this study is to improve engine performance and accommodate technology for the deployment of ethanol gasoline implementations. The experiment was conducted using fuel with a ration octane number (RON) of 92, gasoline-ethanol was executed up to E25 then applied water injection (Wi). The results show that converting a conventional carburetor to EFI and additional water injection increases engine performance, mileage, and reduces exhaust emissions.

Abstract

A novel approach was devised to optimize the stator slot semi-closed type in order improve the magnetic flux connection and minimize iron leakage in high-speed spindle drives. The concept was executed through a combination of response surface approach including the technique of finite element analysis. The primary objective of this investigation would be to provide an engineering approach which improves the functionality of stator criteria, including the stator slot geometry, coil turn per slot, and wire size. The purpose is to achieve higher flux connection and minimize iron leakage. This study presents an enhanced analytical approach that incorporates the analysis of stator flux connection, finite element calculation of flux connection, and iron leakage analysis of stator variables. The results are analyzed through the utilization of finite element computation, and their accuracy is verified through experimental measurements. The findings suggest the ideal design yields increased magnetic flux connection and reduced iron leakage in comparison to the industrial layout. The precision provided by the suggested model is confirmed through the comparison of the simulation and experimental information. In general, the percentage of errors is estimated to be around 7%.

Abstract

The purpose of this study is to examine the performance of the Savonius turbine on the inner blade position in order to improve turbine efficiency. The blades used are a simplification of the Savonius U/L and the Savonius 1:2 double blade model. This research begins by creating four blade models: a single-blade model, a double-blade model at the blade's tip, a double-blade model at the blade's base, a single-blade model, and a double-blade model along the blades against the wind. The four models are then fitted in the test system for generator performance. Next, the efficiency characteristics of the turbine will be tested against rotation. The test results of the four models were evaluated by comparing each model's efficiency. The results indicate that the Savonius double-blade 1:2 and Savonius U/L turbines achieve efficiencies of 2.42% and 2.1% at 5 m/s and 7 m/s, respectively. At speeds of 5 m/s and 7 m/s, the double-tip position inner blade model increased by 81% and 61%, respectively. The double-tip inner blade variant has the maximum efficiency at 9 m/s, at 3.71 percent. Therefore, the Savonius U/L type vertical axis wind turbine with a 1:2 double blade is the most suited blade model for usage at wind speeds less than 7 meters per second. While the Savonius model with innovations in the inner blade double tip position is suitable for operation at wind speeds greater than 9 meters per second, the Savonius model without such advances is not

Abstract

The Throttle Position Sensor (TPS) is one of several sensors involved in electronic control technology in vehicle engines. This sensor is used to determine the throttle opening angle position. For automotive students, understanding how the TPS works is essential. Thus far, in learning about position angle sensors, the component used as a basis is a variable resistor/potentiometer. This component has limitations in terms of accuracy both in stimulus and sensor output. This research aims to develop a practical demonstration of a position angle sensor. The method used in this research is Research and Development (R&D). The research successfully created a demonstration of a position angle sensor with a range of rotation angles from 0° to 300°, with an accuracy of 98%. Throttle Position Sensor (TPS) merupakan satu dari beberapa sensor yang terlibat dalam teknologi pengontrolan elektronik pada mesin kendaraan. Sensor ini digunakan untuk mengetahui posisi sudut bukaan throttle. Bagi peserta didik bidang otomotif pemahaman pada cara kerja TPS menjadi salah satu hal penting. Selama ini dalam pembelajaran sensor posisi sudut komponen yang dijadikan dasar adalah variable resistor / potensiometer. Komponen ini memiliki kekurangan dalam hal akurasi baik pada sisi stimulus maupun output sensor. Penelitian ini bertujuan untuk mengembangkan sebuah peraga praktikum sensor posisi sudut. Metode yang digunakan dalam penelitian ini adalah Research and Development (R&D). Penelitian berhasil mewujudkan peraga sensor posisi dengan range sudut putar 0° hinga 300°. Dengan akurasi sebesar 98%.
