Abstract: An energy and exergy analysis of a four stroke spark ignition engine operated with nano-lubricant is experimentally investigated to assess the environment-engine energy interaction. The warm-up period and the influence of mixing nanoparticle with the lubricant on the exergy rate at various volume fractions VOF are also reported. It was observed that the engine warm-up period is dropped up to 40% when nano-lubricant is employed. The results also showed that presence of nanoparticles in the lubricant would double the exergy potential of the engine. Energy and exergy efficiency are both augmented when nano-copper is mixed with the lubricant.
