Abstract

This paper presents the powertrain conversion of a small diesel-powered tractor into an electric tractor or electric off-road vehicle (EORV), offering a cost-effective alternative to purchasing a new electric model, which may be financially challenging for small-scale farmers. Given that electricity is generally cheaper than diesel fuel in Malaysia, the conversion approach aims to reduce long-term operational costs while maintaining or improving performance. The primary contribution of this work is a systematic and practical method for electric tractor conversion. The process begins with analysing the existing performance and operational requirements of the diesel tractor, followed by the selection of suitable components—namely, the electric motor, battery cells, and other associated systems. These components are then integrated into the tractor, and initial testing was performed. A speed run test was conducted to evaluate the power capability of the converted tractor. Results indicate that the electric motor delivers higher power and speed compared to the original diesel engine. The onboard energy monitoring device recorded a noticeable current spike and voltage sag during acceleration, as expected. The motor power was calculated from the recorded voltage and current data. The data show that the motor output exceeds the rated power of the original engine, suggesting that the system can handle higher loads. Some challenges encountered during the conversion process include the high initial cost, limited availability of components that meet performance requirements, and technical challenges in ensuring the durability and efficiency of the modified drivetrain. In conclusion, further testing under various load conditions is necessary to fully evaluate energy consumption and system performance in real agricultural environments.

Abstract

In the present study, Cu films were made over Al alloy using the electrodeposition technique. Electrodeposition conducted at various currents (80, 100, and 120 mA), with and without influence by a rotating magnetic field (100 rpm of rotation). 0.5 M CuSO4 + 20 mL of H2SO4 was used for electrolyte solutions. The sample before and after electrodeposition was weighed using digital scale to calculate deposition rate and current efficiency. All formed Cu films were characterized using X-ray diffraction (XRD), attenuated total reflectance Fourier transform infrared spectroscopy (ATR-FTIR), Scanning electron microscopy equipped with Energy dispersive spectroscopy (SEM-EDS), and Potentiostat apparatus. Furthermore, antibacterial activity using Staphylococcus aureus was also investigated. Increasing the current of electrodeposition leads to an increase in deposition rate and current efficiency for both conditions (with and without rotating magnetic field influence). Based on the XRD and ATR-FTIR investigation, Cu was successfully deposited onto Al surface. Currents used for the electrodeposition process between 80-100 mA would result in a faceted structure, while using 120 mA results near to spheroidal. Shifting to higher currents leads to decreases in grain sizes and presenting a rotating magnetic field also enhances the grain size. Current and rotating magnetic influences are not linearly influencing corrosion potential, corrosion rate and antibacterial activity. The sample made using higher current plus influencing with a rotating magnetic field has less corrosion rate and higher area of inhibition at around 0.808 mmpy and 4.01 cm2.
