Role of nanolubricants formulated in improving vehicle engines performance

Abstract

Transportation sector is a primary consumer of different energy resources, especially in vehicles. Accordingly, industrial society needs novel affordable strategies, accessible and sustainable for fuel economy and reducing the exhaust emissions from combustion engines. The wear and friction are a principal reason for energy dissipation owing to the frictional losses that reach 17-19% of the engine output power. Improving the tribological properties and engines performance is a straightforward approach for saving energy and decreasing emissions using nanomaterials as eco-friendly based nanolubricants to replace the environmentally harmful additives of the traditional commercial engine oils. This study summarizes the recent advances in the area of nanolubricant additives and engine performance lubricated by nanolubricants additives.
