Design and Fabrication of an Energy-Efficient Hybrid Powertrain for Urban Transport Vehicles

Abstract

The increasing need for sustainable urban transportation solutions has spurred the development of energy-efficient hybrid powertrains. This paper presents the design and fabrication of a novel hybrid powertrain optimized for urban transport vehicles, focusing on enhancing fuel efficiency and minimizing emissions. The proposed hybrid system integrates a high-efficiency internal combustion engine (ICE) with a brushless DC electric motor and a lithium-ion battery pack. The design includes a continuously variable transmission (CVT) to seamlessly combine power sources and an advanced energy management system (EMS) to optimize performance based on driving conditions. Key aspects of the study include the mechanical and electrical integration of components, implementation of regenerative braking, and development of a user-friendly driver interface. Performance analysis through simulation and prototype testing demonstrates significant improvements in fuel economy and emissions reduction compared to conventional ICE vehicles. The fabrication process involves precision manufacturing and stringent quality control to ensure reliability and performance. This research highlights the potential of hybrid powertrains to address urban transportation challenges, offering a viable path towards greener and more efficient city mobility.
