Abstract

Motorcycle engine performance is highly dependent on the air intake system, which plays a crucial role in the combustion process. One common method for improving engine performance is modifying the intake system, either by installing additional devices or adjusting the quantity of incoming air. One innovation that is starting to be widely used is the Jet Ranger, an additional device on the intake duct that is claimed to be able to increase air flow into the combustion chamber. This study aims to determine the effect of the use of Jet Ranger and variations in the quantity of incoming air on the maximum power of a 150 cc motorcycle engine, as well as to analyze the interaction between the two variables. The study was conducted using an experimental method with a two-way factorial approach. The independent variables in this study consisted of two factors, namely the use of Jet Ranger (without Jet Ranger and with Jet Ranger) and variations in the quantity of incoming air divided into four levels (0.008; 0.012; 0.016; and 0.020 kg/s). Maximum power testing was conducted using a Leads dynotest, while the mass of incoming air was calculated based on air velocity measured using a digital anemometer. The test data were statistically analyzed using a two-way ANOVA to identify the effect of each factor and the interaction between them on engine power. The results of the study indicate that the use of Jet Ranger significantly increases engine power. Variations in the quantity of intake air also significantly affect the power generated. In addition, the interaction between the use of Jet Ranger and the quantity of intake air is proven to have a significant impact on increasing the maximum engine power. These results are in line with the theory of intake systems which states that increasing optimal air flow can increase the volumetric efficiency of the engine, and are supported by findings from previous studies. Therefore, these findings can be used as a reference in the development of air intake systems on motorcycles to achieve more optimal engine performance.

Abstract

The development of electric motor vehicles drives the need for efficient, stable, and reliable energy storage systems. This study aims to compare the performance of three types of batteries commonly used in electric motorcycles, namely LiFePO4 (Lithium Iron Phosphate), Li-Ion (Lithium Ion), and Lead Acid (Lead Battery). The parameters tested include energy efficiency, capacity, and performance during the starting process. The test method was carried out for 60 minutes through a charging and discharging process (charge-discharge), using a pzem-015 measuring instrument and a multimeter to monitor the current, voltage, input/output power, and battery capacity. The test results show that the LiFePO4 battery provides the best performance. This battery has the highest efficiency and capacity, reaching 1430 mAh, with a stable average efficiency in the range of 50–60%. In addition, LiFePO4 also produces the highest current and voltage when used for starting, making it very reliable for the initial needs of electric motorcycle operation. Meanwhile, the Li-Ion battery recorded a high initial efficiency of up to 87.27%, but this efficiency decreased and then stabilized at 72%, with a recorded capacity of 1360 mAh. Although its efficiency is quite good, its long-term stability is still below that of LiFePO4. Meanwhile, the Lead Acid battery showed the lowest performance. Its efficiency continued to decline to only 26.3% at the end of the test. Its capacity is 1380 mAh, but the increase is unstable, indicating inconsistencies in power storage and discharge. Based on these results, LiFePO4 batteries are recommended as the main choice for electric motorcycles because they excel in aspects of energy efficiency, performance stability, and long-term durability.

Abstract

Disc discs are the main component in a motorcycle braking system that functions to convert kinetic energy into heat energy through friction. The geometric design of the disc, including the diameter and number of holes, affects the effectiveness of braking as well as the heat dissipation ability. This study aims to analyze the effect of variations in diameter and number of holes on disc discs on braking distance and disc temperature. The research method used was an experimental method with three variations in disc diameter (190 mm, 220 mm, and 260 mm) and three variations in the number of holes (30, 36, and 42 holes). The test was carried out through a controlled braking procedure at an initial speed of 40 km/h on flat road surfaces with stable weather conditions. Braking distance data is measured using ultrasonic sensors, while disc temperature is recorded with a high-accuracy infrared thermometer. The results showed that the diameter of the disc disc had the most significant influence on the braking distance. The larger the diameter, the greater the braking moment resulting so that the stopping distance becomes shorter. The number of holes in the disc also plays a role in heat dissipation because the holes enlarge the heat dissipation area. However, the increase in the number of holes tends to slightly increase the braking distance due to a reduction in the area of frictional contact field. The most optimal configuration is found on a 260 mm diameter disc with 42 holes, which results in the shortest braking distance of 8.25 meters and the lowest temperature rise of 4.47°C.  Statistical analysis using Two-Way ANOVA confirmed that the diameter and number of holes had a significant effect individually, but there was no significant interaction between the two. These findings confirm that the selection of the right disc dimensions is critical to improving braking performance, thermal efficiency, and rider safety.

Abstract

This study aims to analyze the effect of the combination of oil viscosity and shock load on the compression characteristics of telescopic shock absorbers on motorcycles, which include depth, time, and compression speed parameters. The experiment was carried out using two levels of oil viscosity, namely 10 cSt and 15 cSt (equivalent to SAE 10W and SAE 15W), as well as two shock load variations, namely 40 kg and 50 kg, which were dropped vertically from a height of 30 cm. Compression depth measurements were carried out using a slow-motion camera at a speed of 240 fps and the results were validated using Kinovea software. Meanwhile, the compression time measurement is carried out with a stopwatch, and the compression speed is calculated from the results of the comparison between the compression depth and the compression time. The experimental data were analyzed using Minitab software with the Two-Way ANOVA method to determine the influence of each variable on response. The results of the analysis showed that oil viscosity and shock load had a significant influence on the compression depth, while the viscosity of the oil also significantly affected the compression speed. However, neither the viscosity of the oil nor the shock load exerted a significant influence on the compression time. To support the results of the experiment, a mass-spring-damper system theory model approach was used, which represents the dynamic behavior of shock absorbers. This model helps to explain the compression response to changes in fluid and load parameters theoretically. Based on the analysis of experimental results and model simulations, the optimal combination that provides the best performance is found in the use of oil viscosity of 10 cSt (SAE 10W) with a shock load of 50 kg.

Abstract

This study aims to analyze the effect of variations in bi-LED projector power and the use of a voltage stabilizer on the luminous flux on a motorcycle. The luminous flux produced by a motorcycle lighting system plays a very important role in improving rider visibility and safety, especially at night. Therefore, this study uses a quantitative experimental method with a two-way factorial approach (Two-Way ANOVA) to test the effect of two main variables, namely the bi-LED projector power and the voltage stabilizer configuration. The power variables tested include three power levels, namely 35 W, 70 W, and 105 W, while the voltage stabilizer configuration includes three conditions, namely without a stabilizer, 14 V, and 14.5 V. Luminous flux measurements were carried out using a lux meter at a distance of five meters from the reflective surface, and the results were then combined into lumen units to facilitate comparison between power variations and stabilizers. The results showed that increasing the bi-LED projector power significantly increased the luminous flux produced. The 105 W power output produced the highest luminous flux, reaching 42,319 lumens when combined with a 14.5 V voltage stabilizer. This demonstrates that the combination of high power and proper voltage stabilizer use can improve the quality of motorcycle lighting. The very low P-value (0.000) and R² of 100% indicate that the predictive model used in this study is robust and reliable. Overall, this study emphasizes the importance of using a voltage stabilizer in motorcycle lighting systems. A voltage stabilizer is not only a complementary device but also a crucial component for improving visibility and driving safety, especially at night. Therefore, proper use of a stabilizer can improve lighting performance and provide significant safety benefits.
