The engine warm-up period is one of the most important factors of high fuel consumption and poor engine performance due to factors such as lack of proper fuel evaporation, lack of complete fuel combustion, premature shutdown of the flame front, and infiltration of hydrocarbon substances such as engine oil into the combustion chamber. In this research, the effects of adding copper nanoparticles to engine oil with different weight concentrations of 0%, 0.2% and 0.4% on fuel consumption and engine performance during the engine warm-up period have been investigated. The engine oil used was a standard engine oil with a nominal concentration of 20w-50 with an API SL/CF quality level and the engine used was an air-cooled single-cylinder gasoline internal combustion engine. The results of this research indicate that the use of engine oil containing 0.2% and 0.4% nanoparticles, respectively, reduced fuel consumption by 5% and 9.1% during the warm-up period.
