Comparative Study of IC Engine and Electric Powertrains for Go-Kart Applications

Abstract

A go-kart is a small, lightweight four-wheeled vehicle designed for recreational, educational and competitive driving. This project deals with the design and fabrication of a go-kart powered by an internal combustion (IC) engine. The main objective is to develop a simple, strong, economical and serviceable vehicle using commonly available mechanical components and workshop processes. The project covers the selection of the IC engine, chassis design, steering system, braking system, power transmission, wheels and tyres, accelerator and control mechanism. The frame is designed to support the engine, driver and other components while maintaining adequate rigidity and stability. The engine converts the chemical energy of fuel into mechanical power, which is transmitted to the driving axle through a suitable transmission arrangement. The methodology includes requirement identification, conceptual design, component selection, basic engineering calculations, CAD/drawing preparation, material procurement, fabrication, assembly and testing. The report also discusses important safety aspects such as braking performance, steering response, chain guarding, fastener tightening and driver protection. The project provides practical understanding of automobile engineering, IC engines, manufacturing processes, machine design, welding, power transmission and vehicle testing. The final design can be further improved by reducing weight, improving ergonomics, optimizing power transmission and introducing additional safety and instrumentation.
