E-engine for a long-tail boat, an application in asean (Association of southeast asian nations)-design and comparison with internal combustion engine

Abstract

An Electric propulsion (E-propulsion) system for ASEAN (Association of Southeast Asian Nations) long-tail boat is proposed in this article. It offers several advantages over a traditional internal combustion engine propulsion system. Besides low noise and zero-emission, characteristics of electric engine (E-engine) allow regenerative braking and starting the propeller in the water. A design of E-engine has been achieved through finite element analyses and lump-parameter thermal simulations. It shows better performances than Honda GX270 internal combustion engine in terms of volume, weight, torque, and power. A full scale prototype of E-engine was manufactured. Experi-ments have been conducted on an engine test bench. Torque, power, efficiency and temperatures were well aligned with the simulation results.
