Abstract

This study addresses the need for enhanced vehicle cooling systems as modern engines operate under increasingly harsh conditions, necessitating efficient heat dissipation to prevent overheating and optimize fuel efficiency. The aim of this research is to investigate the combined effect of adding Al₂O₃ nanoparticles and applying ultrasonic vibration on the heat transfer performance of automotive radiators. Experimental tests were conducted with various concentrations of Al₂O₃ nanoparticles, and ultrasonic vibrations were applied to assess their impact on fluid temperature, temperature differences across the radiator, and overall heat transfer rate. The results demonstrate that the addition of Al₂O₃ nanoparticles significantly improved the thermal conductivity and temperature differential (ΔT) between the inlet and outlet of the radiator. Furthermore, ultrasonic vibration enhanced heat transfer by disrupting the thermal boundary layer and increasing fluid turbulence. Notably, the combined use of both techniques resulted in a significant increase in the heat transfer coefficient (U) and the heat transfer rate (Q). These findings contribute to the existing body of knowledge by showing that the synergistic application of nanoparticles and ultrasonic vibrations offers an efficient solution for improving vehicle cooling systems without requiring substantial design changes.

Abstract

The automotive industry is rapidly evolving with the adoption of advanced technologies, one of which is Electric Power Steering (EPS). EPS technology replaces traditional hydraulic steering systems with an electric system that is more efficient, precise, and environmentally friendly. However, the lack of structured learning modules and teaching materials on EPS poses a challenge in vocational education within the automotive field. This community service program aims to develop a comprehensive learning module that includes the fundamental theory of EPS, practical procedures using the EPS engine trainer, jobsheets for practical activities, and troubleshooting and maintenance guidelines for EPS systems. The module is designed to enhance the understanding of students, the skills of technicians, and to support lecturers in delivering the material effectively. Through a trial run at the Automotive Electrical Engineering Study Program at Politeknik Negeri Malang (POLINEMA), the developed module successfully improves the quality of learning and helps students master EPS technology. Evaluation results indicate that the module effectively aids students in better understanding EPS concepts and performing practical procedures in a systematic manner. It is expected that this module will serve as an important reference in vocational automotive education in Indonesia, especially in response to the ongoing advancements in automotive technology
