Fuel consumption reduction in Bus Vehicles
Fuel consumption reduction in Bus Vehicles
This project is focused on enhancing bus efficiency by minimizing fuel consumption, revamping a traditional bus design to use less fuel without sacrificing performance or comfort. Traditional bus vehicles are subject to outdated designs as a key factor contributing to inefficiency in fuel usage. With design adjustments to enhance aerodynamics, the drag factor is reduced by 45%, saving 27% fuel mass.
Objectives:
• Drag force reduction
• CFD Analysis
