Abstract

Engine overheating is a critical condition that can cause damage to internal components, reduce operational efficiency, and lead to overall system failure. The absence of an automatic protection system is one of the primary factors contributing to damage. This study aims to design and test a temperature sensor-based safety device that can automatically cut off the engine's working system when the temperature exceeds the safe limit. The method used is descriptive statistical analysis to evaluate the effect of independent variables (operational time duration and workload) on the dependent variable (coolant temperature). The system was tested through water heating simulation using an electric heater and controlled by an Arduino Nano microcontroller, a MAX6675 temperature sensor. Testing was carried out with variations in power load (150, 300, 450, 600, and 750 Watts) and operational duration (20, 40, and 60 minutes). Temperature data were collected and analyzed using ANOVA to determine the effect of load and time on temperature increase. The results showed that the temperature increased significantly with increasing power load, with temperatures approaching 100°C at loads ≥450 Watts in less than 20 minutes. The load variable shows a significant effect on temperature (p < 0.05), while the duration of time shows a nonlinear but not statistically significant upward trend. The safety device is proven to be able to automatically disconnect the system when the temperature reaches the specified maximum limit, thus effectively preventing engine damage due to overheating.

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

Dependence on fossil fuels, such as gasoline and diesel, has become a global issue that affects environmental sustainability and energy security. Increasing greenhouse gas emissions, decreasing natural resource reserves, and instability of global energy prices encourage the need for innovation in motor vehicle fuel systems. This study aims to assess fuel efficiency and engine performance on a 110 CC motorcycle with a standard compression of 10.7:1, by utilizing a mixture of RON 90 gasoline and alcohol. The main focus of the study is to compare the effect of varying alcohol content on engine power output, with mixtures of E12.5, E17.5, and E22.5. The method used is an experimental method with three variables, namely the independent variable (type and content of fuel mixture), the dependent variable (engine power), and the control variables (engine condition, temperature, and testing method). Testing was carried out using a combination of iridium spark plugs and standard spark plugs, as well as variations in Pilot Jet sizes 34 and 35 on aftermarket carburetors. Each combination was tested to determine its effect on the maximum engine power. The results showed that a blend of E12.5 fuel with Pilot Jet 35 and iridium spark plugs produced the highest power output compared to other tested combinations. This combination was proven to optimize combustion in the combustion chamber, thereby improving engine efficiency and performance. Conversely, increasing the alcohol content above E12.5 did not provide a significant increase and even tended to decrease power due to alcohol's lower calorific value than gasoline. The conclusion of this study is that the use of an aftermarket carburetor with Pilot Jet 35 and iridium spark plugs, combined with an E12.5 fuel blend, can be an effective alternative for improving the performance of a 110cc motorcycle. These findings are expected to serve as a reference for the development of more efficient and environmentally friendly blended fuel technology.
