This article reports the effects of CuO/water based coolant on specific fuel consumption and exhaust emissions of four stroke single cylinder diesel engine.The CuO nanoparticles of 27 nm were used to prepare the nanofluid-based hanes 42tb engine coolant.Three different volume concentrations (i.e 0.05%, 0.

1%, and 0.2%) of CuO/water nanofluids were prepared by using two-step method.The purpose of this study is to investigate the exhaust emissions (NOx), exhaust gas temperature and specific fuel consumption under different load conditions with CuO/water nanofluid.After a series of experiments, it was observed that the CuO/water nanofluids, even at low volume concentrations, have a significant influence on exhaust emissions.The experimental results revealed that, at full load condition, the specific fuel consumption was reduced by 8.

6%, 15.1% and 21.1% for the addition of 0.05%, 0.1% and 0.

2% CuO nanoparticles with water, respectively.Also, the emission tests were concluded that 881 ppm, 853 ppm and 833 ppm of mango veranda rose NOx emissions were observed at high load with 0.05%, 0.1% and 0.2% volume concentrations of CuO/water nanofluids, respectively.
