Abstract

Penelitian ini bertujuan untuk menganalisis pengaruh variasi sudut intake manifold terhadap performa mesin sepeda motor Yamaha Aerox New Connected yang telah dimodifikasi dengan mesin performa tinggi dan ECU programmable. Tiga sudut intake manifold yang diuji adalah 90°, 126°, dan 160°, dengan parameter pengujian meliputi aliran udara (CFM) menggunakan flowbench, serta daya (HP) dan torsi (Nm) menggunakan dynamometer. Sepeda motor yang digunakan telah dimodifikasi dengan kapasitas mesin 182 cc, throttle body 34 mm, porting head, camshaft custom, dan ECU UMA Racing M9. Hasil pengujian menunjukkan bahwa intake manifold dengan sudut 90° menghasilkan aliran udara tertinggi, dengan rata-rata 94,20 CFM, menunjukkan efisiensi volumetrik terbaik. Sementara itu, sudut 126° dan 160° masing-masing menghasilkan 91,64 CFM dan 89,94 CFM. Meskipun sudut 90° unggul dalam efisiensi aliran udara, intake manifold dengan sudut 160° mencatatkan performa tertinggi dalam hal daya dan torsi pada RPM rendah hingga menengah, dengan rerata daya maksimum 16,3 HP dan torsi maksimum 30,08 Nm. Kesimpulannya geometri intake manifold memiliki pengaruh signifikan terhadap karakteristik aliran udara dan performa mesin. Sudut yang lebih tegak seperti 90° cocok untuk efisiensi volumetrik tinggi, sedangkan sudut lebih landai seperti 160° lebih optimal untuk torsi dan daya pada RPM rendah. Penggunaan ECU programmable memungkinkan penyesuaian parameter mesin secara presisi, sehingga mendukung optimasi performa sesuai konfigurasi intake yang digunakan. Dengan demikian, pemilihan sudut intake manifold harus disesuaikan dengan kebutuhan performa dan karakter penggunaan kendaraan.

Abstract

This research is motivated by the development of injection motorcycle engine management system technology that demands increased performance through optimization of the Electronic Control Unit (ECU). This study aims to analyze the performance comparison of the Yamaha MX King 180 cc using a standard ECU and a racing ECU on engine power and torque. The method used is an experiment with engine dynotest testing in the range of 6000-10000 RPM. The research sample is a 2015 Yamaha MX King unit that has been modified to 180 cc. Data were collected through direct measurements of power (HP) and torque (Nm), then analyzed descriptively in the form of tables and graphs. The results show that the racing ECU is able to produce a higher maximum power of 24.9 HP at 10000 RPM compared to the standard ECU of 22.2 HP at the same engine speed. In terms of torque, both types of ECU reach peak values ​​at 8000 RPM with a relatively small difference (18.18 Nm on the standard ECU and 18.15 Nm on the racing ECU). However, at low to mid-range revs, the racing ECU tends to produce slightly more torque, although at very high revs, it experiences a greater decrease compared to the standard ECU. The racing ECU excels at increasing high-rev power, while the standard ECU exhibits more consistent torque stability. Therefore, the choice of ECU type must be tailored to the performance requirements and the characteristics of the vehicle's use.

Abstract

Surface roughness is a critical indicator of machining quality, directly affecting the functional performance and service life of manufactured components. This study aims to optimize the surface roughness of AISI 1045 steel by varying parameters (cutting speed, feed rate, and depth of cut) using Taguchi L9 orthogonal array. Experiments were conducted on a FANUC 0i-Mate CNC lathe using Al-TiN-coated VNMG inserts. Moreover, the surface roughness was measured in accordance with ISO standards. Analysis of Variance (ANOVA) revealed the depth of cut was the most influential factor (45.21%), followed by cutting speed and feed rate. The Signal-to-Noise (S/N) ratio was identified as optimal surface roughness of 0.323 µm (N5 grade) at the parameter, with a cutting speed of 240 mm/min, a feed rate of 0.2 mm/rev, and a depth of cut of 0.6 mm. The novelty of this study is the demonstration that Taguchi's design and ANOVA combined can achieve reliable optimization results with considerably reduced experimental effort and offer practical industrial deployment, including for Small and Medium-sized Enterprises (SMEs).

Abstract

This study aims to determine the effect of methanol-blended fuel variations on fuel consumption and exhaust emissions Honda Supra X125 FI. The background of this research is the need for environmentally friendly and efficient alternative fuels to reduce air pollution from motorized vehicles. Methanol was chosen as an additive due to its high octane number and oxygen content in its structure, which can improve combustion efficiency. The tests were conducted using a Honda Supra X125 FI motorcycle with five fuel mixture variations: 0%, 5%, 10%, 15%, and 20% methanol in Shell V-Power. Data were collected using a gas aalyzer and a dynamometer to measure fuel consumption and CO and HC emission levels. The results show that methanol addition increases fuel consumption by up to 17.99% in the 20% methanol mixture due to methanol's lower calorific value compared to gasoline. However, CO emissions decreased by 23% and HC emissions by 19.26%. The 10% methanol mixture is optimal as it balances combustion efficiency and fuel consumption. The findings indicate that methanol has potential as a fuel additive for reducing emissions in gasoline motorcycles, although higher methanol concentrations may increase fuel consumption.

Abstract

This research is to determine the effect of variations in the intake manifold curvature angle on turbulence intensity, turbulent kinetic energy, flow velocity, and fluid flow patterns. One effort to reduce excessive fossil fuel consumption is modifying vehicles to consume fuel more efficiently through a more complete combustion process. One such method involves modifying the intake manifold of a motorized vehicle. This study used FD-based numerical study with a quantitative approach to investigate changes in the curvature angle of the intake manifold. The aim of The modification process of the intake manifold structure was conducted on a 2012 Vario 125 (KZR) motorcycle through simulation. The purpose of this simulation is to conduct a fundamental analysis before implementing changes to the intake manifold structure. The geometric definition of the intake manifold was created using SolidWorks 2020, and the simulation was performed using Ansys Workbench 2022. The curvature angle variations of the intake manifold were 110°, 120° (standard), and 130°. The simulation results showed differences in outcomes for each curvature angle. The highest turbulence intensity, turbulent kinetic energy, and flow velocity were observed at the 110° angle. This indicates that modifying the intake manifold through simulation can influence turbulence flow during the combustion process. These findings can be considered to achieve better torque and power output in vehicles in the future.

Abstract

Crude oil reserves are steadily depleting. One viable alternative is the use of biodiesel fuel in diesel engines. However, a major drawback of biodiesel is its susceptibility to degradation due to low oxidative stability. Antioxidants are compounds that inhibit or slow down the oxidation process by preventing the formation of oxidants or reducing the propagation of free radicals. This study aims to investigate the effect of adding antioxidant additives derived from Moringa oleifera bio-oil, produced through pyrolysis, to B30 biodiesel fuel at concentrations of 0, 500, 1000, and 1500 ppm on the performance of a multicylinder diesel engine. A quantitative approach was employed using an experimental method, and data analysis was conducted using descriptive analysis. The results showed that fuel consumption decreased with the addition of Moringa oleifera antioxidants, with reductions of 5.31%, 6.66%, and 7.08% at 500 ppm, 1000 ppm, and 1500 ppm, respectively, at an engine speed of 2500 rpm. The highest torque was achieved with 1000 ppm of Moringa oleifera antioxidant at 2728 rpm, reaching 111.9 Nm (an increase of 4.48%), while the highest power output was also obtained at 1000 ppm, reaching 70.9 HP at 5100 rpm (an increase of 3.2%).

Abstract

This study investigated the effects of camshaft modification and fuel variation on fuel consumption and air–fuel ratio (AFR) in a Honda Supra X 125 motorcycle. An experimental design was employed using three camshaft configurations standard, touring, and racing and two fuels: pure Pertamax and Pertamax blended with an octane booster. Fuel consumption was measured at idle and 5000 rpm based on the time required to consume 20 mL of fuel, while AFR was measured under idle conditions. Each test was repeated three times, and the results were expressed as mean ± standard deviation. At idle, the standard camshaft produced the longest fuel-consumption time, reaching 8.14 ± 0.09 min/20 mL with pure Pertamax and 9.22 ± 0.06 min/20 mL with the blended fuel. At 5000 rpm, the touring camshaft with the blended fuel produced the longest consumption time at 3.20 ± 0.05 min/20 mL. The racing camshaft consumed fuel more rapidly, with the lowest idle value of 6.57 ± 0.35 min/20 mL using pure Pertamax. AFR values decreased from 14.02 ± 0.06 for the standard camshaft with pure Pertamax to 13.45 ± 0.06 for the racing camshaft with the blended fuel. These findings indicate that camshaft geometry and fuel composition influence fuel-consumption characteristics and mixture richness. The standard camshaft was most efficient at idle, the touring camshaft performed best at 5000 rpm, and the racing camshaft produced the richest mixture.
