Abstract

This research is experimental research using a 110 cc petrol engine with a chassis type dyno test measuring instrument. This research aims to determine the performance and exhaust emissions when using LPG and pertalite gas. The engine speed variation in this research is 2500-5000 rpm. Data collection techniques use observation techniques to record the test results obtained. The data analysis technique uses descriptive analysis to present research results. As for the research results from the engine performance analysis, it was found that there was an increase in engine performance at each engine rotation, the lowest power was obtained when using LPG gas fuel at 2500 rpm of 2.22 kW and pertalite fuel of 2.73 kW. Meanwhile, the highest power was obtained when using LPG gas fuel at 5000 rpm of 4.88 kW and using pertalite fuel of 4.81 kW. However, for fuel consumption, the lowest consumption was obtained when using LPG gas. Meanwhile, for exhaust gas emission analysis, it was found that there was a decrease in emission levels when using LPG gas. It was found that CO and HC exhaust emissions increased as the engine speed increased, so emissions decreased further. However, CO2 gas emissions increase with each engine rotation compared to using LPG gas.

Abstract

Gasoline fuel is a kind of fossil fuel that is still the primary fuel for vehicles and motorcycles nowadays. Demand for fuel continues to increase from time to time, so an effort is needed to save the use of fuel. This research is intended as an initial study to determine the quantity of heat energy converted and distributed into several engine performance parameters. Furthermore, the results of this study became the basis for the development of similar research to produce high engine performance and low emissions as well as economists by setting combustion parameters. The result shows that only a small portion of the heat generated from pertalite fuel is used as effective power. Most of the heat energy from the fuel is wasted in the environment and distributed into radiant heat, and some of it becomes heat to the exhaust gases and heat to the cooling water.

Abstract

PeneIitian ini berbasis pada penerapan hukum termodinamika pertama yang bertujuan untuk mengukur distribusi energi yang dihasilkan dari pembakaran bahan bakar gasoline (E0) dan campuran gasoline-bioethanol (E50) pada mesin spark ignition. Pengujian dilakukan pada parameter pembakaran standar mesin yaitu rasio kompressi 11:1 dan pengapian 12 BTDC. Sementara itu, variasi volume injeksi dalam rentang 100% - 200% (penambahan 25%) pada bahan bakar E50 dilakukan untuk mengetahui pengaruh variasi volume injeksi bahan bakar E50 terhadap laju energi pada daya poros, gas buang dan kerugian energi. Hasil penelitian menunjukkan bahwa energi bahan bakar campuran gasoline dan bioethanol (E50) lebih tinggidari pada energi bahan bakar, kecuali jika volume injeksi E50 sama dengan E0. Akan tetapi energi bahan bakar E0 dengan nilai rata-rata 16,62 kW realtif akan sama dengan E50 dengan nilai rata-rata 17,45 kW, jika bahan bakar E50 diinjeksikan pada volume 125% atau 0,25 kali lebih besar dari injeksi bahan bakar E0. Hasil penelitian ini juga menunjukkan bahwa semakin naik injeksi bahan bakar E50, maka energi bahan bakar akan semakin meningkat rata-rata sebesar 2,7 kW setiap kenikan volume injeksi 25%. Energi bahan bakar terkecil dari E50 adalah rata-rata 15,18 kW dan terbesar adalah 25,84 kW yang masing-masing diperoleh pada volume injeksi 100% dan 200%. Induksi bahan bakar E50 yang dianggap cocok untuk diaplikasikan pada mesin bensin adalah pada volume injeksi 125%. Pada kondisi tersebut distribusi energi pada daya dan gas buang untuk E50 pada durasi injeksi 125% masing-masing adalah 6,59 kW dan 4,70 kW, sedangkan untuk E0 masing-masing adalah: 6,35 kW dan 6,19 kW dan sisanya diidentifikasi sebagai kerugian energi.

Abstract

This research is a type of experimental research which aims to determine the effect of varying the diameter and number of groundstrap turns on the spark plug cable on power, torque, AFR and fuel consumption of a 150 CC motorbike engine. The results of the research show that there is a significant influence on engine power by using variations in the 0.3 mm diameter of the 260 winding groundstrap with an increase of 0.53 hp. When varying the diameter of 0.6 mm of winding 155 on power there is a significant influence with an increase of 0.52 HP and using a variation of 0.9 mm of winding 103 on power there is a positive influence with an increase of 0.43 HP. The use of groundstrap on engine torque with three types of variations increased by 1.03 Nm, 0.63 Nm and 0.75 Nm. There is no significant effect of using groundstrap on AFR. For the effect of using a groundstrap on fuel consumption, the variations with the most positive influence are the 0.3 mm diameter of the 260 winding and the 0.6 mm diameter of the 155 winding.

Abstract

The primary objective of this study is to evaluate the impact of providing a ground strap on the spark plug cable with varying diameters of the ground strap winding at 0.3, 0.6, and 0.9 mm. The evaluation was conducted on a 150 cc single-cylinder spark ignition engine. The engine was operated under Wide Open Throttle (WOT) conditions, with a speed ranging from 2000 to 7000 rpm in increments of 1000 rpm. The length of the ground strap winding on the spark plug cable was 23 cm, while the diameter of the spark plug cable was 0.8 mm, and its length was 23 cm. The data collected were the engine's performance results under standard conditions and at each variation of the ground strap diameter. The findings revealed that the smaller the ground strap diameter, the greater the improvement in engine performance. The provision of a ground strap on the spark plug cable significantly reduces the engine's specific fuel consumption compared to the engine without a ground strap, with an average reduction of 4.451%. Additionally, the air-fuel ratio value deviates from the stoichiometric condition by 9.25% at the best winding of 0.3 mm. On average, installing a ground strap on the spark plug cable also results in an increase in torque and engine power by 5.91% and 6.22%, respectively

Abstract

This study has a purpose to determine the number of blades effect on a water turbine regarding flow rate and turbine rotation. The turbine utilized in this study is a Pelton-type impulse turbine, which harnesses potential energy and water pressure to enhance its rotational speed. Additionally, it examines how turbine rotation affects voltage, current, and electric power generated. This research is an experimental study focusing on a prototype mini-micro hydro water turbine. The testing involved varying the valve openings at angles of 36°, 54°, 72°, and 90°, as well as the number of blades, which were set to 6, 8, and 10. The output parameters were measured using instruments that met the specifications for the test equipment. The results indicated that the minimum water discharge required to drive the turbine prototype was 30 cm³/s at a valve opening of 36°. The minimum power generated for each variation in the number of blades was as follows: 0.114 W for 6 blades, 1.426 W for 8 blades, and 1.672 W for 10 blades. At the maximum valve opening of 90°, a flow rate of 67 cm³/s was achieved. Under these conditions, the turbine generated powers of 1.5 W for 6 blades, 7.593 W for 8 blades, and 8.16 W for 10 blades. These findings demonstrate that the performance of the micro-hydro power generation system is significantly influenced by water discharge, turbine rotation speed, and the specifications of the power generator used. This study provides valuable insights for developing renewable energy sources to supply electricity in remote areas with limited access to conventional energy. Furthermore, the results can serve as a foundation for designing more efficient and sustainable micro-hydro systems in the future. The results indicate that an increase in the number of turbine blades leads to greater kinetic energy in the water, which in turn raises the rotational speed of the turbine. This increase in kinetic energy enhances the conversion of water energy into mechanical energy, resulting in improved efficiency of the turbine.
