Nitrogen Gas in Tyres. Their Impact on Vehicle Operational Safety and Economy

Abstract

In the operation of passenger vehicles, fuel economy is linked to the way the vehicle is operated. Economical control of the vehicle depends on the engine, transmission, aerodynamic resistance and rolling of the vehicle. Engine, transmission, and aerodynamic losses are usually associated with the construction of these vehicle parts, while rolling losses are related to the vehicle tires and are the only vehicle part in direct contact with the road. The rolling resistance of inflated tires is an important component of the resistance that affects the movement of the vehicle and contributes to the fuel consumption of the vehicle. Much of the research has focused on how various tire parameters (e.g., load, inflation pressure, and speed) affect rolling resistance to increase fuel economy. Recent researches show that tires inflated with nitrogen gas can maintain proper pressure and reduce rubber wear. Therefore, the purpose of this study is to investigate the impact of the use of nitrogen-inflated tires on vehicle safety, performance improvement and reduction of operating costs.
