Abstract

Brown gas, known as H2O2 (Oxyhydrogen) obtained from electrolysis process can be mixed with gasoline and used in the internal combustion engines. Uncontrolled mixing of Brown gas in the internal combustion engines reduces the quality of burning (engine performance). In this paper, the development and application of the Brown gas generator with 6 chambers in series-equipped with controller is reported. The gas production rate was controlled by regulating the supply current using Pulse Width Modulation (PWM). The characteristic of the Brown gas supply system was tested for various concentrations of the catalyst (KOH) and temperatures. The Brown gas supply system was then applied to the carburetor type engine of 1300 cc and the engine performance was tested. The test results show that the maximum production of gas occurred at 30% of catalyst (KOH) and the production of gas is proportional to the room temperature. The engine performance test result show a 30% reduction of specific fuel consumption after installation of the Brown gas supply system to the engine. The emission test results show 0.67% to 0.12% reduction of CO and 16.9% to 15.5% reduction of CO2.

Abstract

Perkembangan teknologi pada mobil semakin banyak. Salah satunya Limited Slip Differential (LSD), yang diaplikasikan pada sistem powetrain dari mobil. Ketika mobil berbelok dan salah satu roda kehilangan gaya normalnya maka mobil akan mengalami guling, kemudian roda yang menempel dijalan akan kehilangan traksinya. Maka dari itu perlu adanya analisa kebutuhan LSD terhadap power, torsi dan kecepatan yang dapat disalurkan pada setiap variasi locking percentage. Dalam penelitian ini, analisa perhitungan dilakukan berdasarkan FBD mobil pada saat berbelok pada lintasan student formula. Menghitung kecepatan yang diijinkan, kemudian menghitung kecepatan yang harus ditempuh, selanjutnya analisa skid dan guling, dan yang terakhir menghitung Road-Load Horse Power (Rhp), Torsi roda saat berbelok yang dapat disalurkan oleh LSD pada salah satu roda. Perhitungan pada analisa ini diberikan variasi clutch plate (0011/60%, 0101/100%) dan variasi ramp angle (90o/0%, 60o/29%, 50o/42%, 45o/51%, 40o/60%, 30o/80%) yang dilakukan pada skidpad (R=8,55m), hairpin turns pada autocross dan endurance (Rmin=4,5m) serta pada constant turns pada autocross dan endurance (R=11m-27m). Dari analisa radius kritis (hairpin turns) yang dipengaruhi LSD didapatkan hasil penggunaan LSD akan optimum pada locking pecentage LSD terbesar, ketika mobil SAS 6 melaju dengan kecepatan 18,37 m/s, akan menyebabkan roda mobil terangkat maksimal pada hairpin turns radius 4,5 m dengan sudut angkat 17,999o. Dan ketika tidak menggunakan LSD (LP=0%) maka tenaga mobil (Rhp) adalah 0 watt dan menghasilkan kecepatan untuk melaju 0 m/s, serta torsi pada roda bagian luar 3,884 Nm. Ketika menggunakan LSD dengan locking percentage (LP) 88%, mobil akan memiliki tenaga (Rhp) sebesar 2477,352watt yang akan menyebabkan mobil memiliki kecepatan 17,480m/s dan torsi roda sebesar 17,999Nm. Dan untuk pemilihan LSD harus memiliki initial torque sama dengan nilai torsi roda pada saat roda mulai terangkat.

Abstract

Brake lining technology is developing rapidly to adjust the absorption media in which the vehicle's braking system is operating. Material commonly used as a brake lining is asbestos and its alloys, but this material is very dangerous to the environment and health. This research was developed to overcome these problems, namely finding alternative brake lining pads material that has good mechanical and physical properties. Brake lining material is made from a hybrid composite reinforced basalt, shellfish, alumina, and phenolic resin (PR-51510i) as a binding matrix. This brake lining material is produced through a process of sintering at a temperature of 150 ° C with a load of 2000 kg for 30 minutes. These hybrid composites are made in as many as three variations, each of which is tested for olie absorption at several variations of immersion time. Immersion 3 days hardness of hybrid composite and asbestos brake lining material is still quite high between 24-28 HVN. The highest hardness at that time was an H1 specimen of 28.00 HVN. Then the hardness of the brake lining material decreases with the addition of immersion time and is close to stable at the

Abstract

Electronics Continuous Variable Transmission (ECVT) is a smart transmission that has unlimited gear ratios. By analyzing vehicle conditions, ECVT can choose the most efficient gear ratio. ECVT mode requires a Planetary Gear Set (PGS) as a power splitter. This research will use PGS and double electric motor to combine the ECVT mode with electric vehicles to determine the desired speed ratio. The PGS was designed by an analytical model and simulated using CAD software. The simulation will provide several input variations to get the right speed ratio, such as speed variations and rotational direction. The analytical model obtained a PGS ratio of 1:6 with 19 sun gear teeth, 95 ring gear teeth, 38 planet gear teeth, and a motor power of 47 kW. Simulation results will be applied to build the prototype that will be made with a 3D printer. This study shows that ECVT can be a transmission system for electric vehicles with 2 to 5 levels of transmission, and using double electric motors with small power can replace an electric motor with large power. To obtain maximum efficiency, a good control strategy is needed. The control strategy will be discussed in further research.

Abstract

The development of science and technology in automotive field increases as the time went by. The conventional vehicle nowadays has a negative impact on the environment, for example gas emmisions. To cope with the impact the innovation in electric vehicle (EV) is needed. In this research, there are three stages obtain a desired outcome: the data collection stage, the calculation stage, and the analysis stage. For the data collection, there are two methods; the experimental and the simulation stage. For the experimental, dynotest needs to be performed, while in the simulation is to obtain the data generated by Solidwork. In the calculation stage, the maximum speed, traction force, power generated, energy consumption, energy requirement, and slip and skid speed were calculated to obtain the desireable performance. Then, the analysis was performed to compare the performance of ICE and designed BEV and comply with the theories. The results from this research for converting ICE to BEV are re-design of the transmission and replace the engine into BLDC motor. The transmission needed for BEV is two-speed transmission while the motor used is 60 kW BLDC motor. The BEV can performs maximum climb-ability of 30◦ and reaches the maximum speed of 136 km/h in flat road while ICE only have climb-ability of 30◦ and same maximum speed as BEV. The energy consumption of BEV is 0.431 kW.h/km while ICE version is 0.539 kW.h/km. The battery used is Li-ion Ploymer 39 kW.h due to better specific energy and less toxic. For turning behavior, ICE have the safer driving behavior due to the center of gravity and understeer tendency than BEV. But the BEV still save to drive in certain turning speed.

Abstract

Overheating is a failure mode that significantly affects the reliability of electronic devices. All electronic devices, including a 3-phase inverter driving a traction motor, produce heat dissipation. Heat dissipation needs to be controlled with cooling to prevent overheating. Overheating can be avoided by increasing cooling or reducing heat dissipation. Heat dissipation in the 3-phase inverter is caused by the internal resistance of the metal–oxide–semiconductor field-effect transistor (MOSFET), switching loss, and other factors. Cooling for the 3-phase inverter can use water coolant or air coolant. The cooling system is based on the amount of heat dissipation produced. Cooling of a 3-phase inverter can use air coolant with the addition of an extended surface area in the heat sink. The heat sink uses aluminum material, often called pin fin. There are kinds of aluminum available in the market. We calculated heat generation based on the MOSFET's internal resistance, switching loss, and other factors. We validated the simulation results experimentally using a thermal camera. Thus, we could find an optimal number, dimensions, and aluminum type of fin for the cooling system in the 3-phase inverter.

Abstract

The regenerative braking effectiveness of electric vehicles (EVs), with 8-25% range, requires designers to produce better braking systems. The antilock braking system (ABS) was chosen because it offers various advantages, such as enhanced safety considerations, vehicle maneuverability, and so on. The measurement findings revealed that ABS took longer to stop the wheels with the same wheel rotation speed. Because of the lesser differentiation of magnetic flux to time, it created lower induced emf in the generator. ABS 50 Hz performance was 19.5% at 4500 pm, whereas hydraulic brake performance was 21% at the same speed. ABS used model-based algorithms (MBAs) to boost the friction frequency with the wheels from 10 to 50 Hz. As the frequency increased, the ABS graph approached the hydraulic graph, and the ABS performance improved. Although ABS loses to hydraulics in stopping wheel rotation, it gains in saved energy and battery temperature. Longer wheel stop-times allow the rotational kinetic energy of the wheel more time to be converted into electricity.

Abstract

Para nelayan yang terletak di pesisir pantai utara kota Probolinggo, setiap hari harus melaut untuk menjaring ikan. Selama melaut, para nelayan membutuhkan listrik yang sangat banyak sehingga memerlukan biaya bahan bakar yang mahal. Sementara itu di laut terdapat sumber energi yang dapat dimanfaatkan yaitu energi gelombang laut. Berdasarkan dari permasalahan tersebut, maka Tim Abmas KKN, Departemen Teknik Mesin, ITS tahun 2024, merancang mekanisme Pembangkit Listrik Tenaga Gelombang Laut (PLTGL), yang dipasang pada kapal nelayan. Mekanisme ini terdiri dari turbin air, susunan roda gigi, generator dan frame. Turbin air dipasang menyentuh air, sehingga dapat bergerak karena aliran arus laut. Gerakan rotasi dari turbin air dihubungkan dengan generator dan menghasilkan listrik. Kemudian listrik yang dihasilkan dapat disimpan di battery dan digunakan selama melaut. Karena kapasitas dari generator kecil, maka mekanisme ini bisa dipasang beberapa sehingga dapat memenuhi kebutuhan listrik selama di laut. Pemakaian mekanisme PLTGL ini, mampu mereduksi biaya operasional setiap harinya.
