In this article, results of testsperformed to study the impact of Zinc Oxide (ZnO) nanoparticles as a fuel additive on the parameters of performance and emissions of an SI engine run with blends of gasoline and ethanol were presented. Experiments were done on a single cylinder port fuel injection (PFI) petrol engine, at 2500 RPM engine speed (constant) and at different loads. Ethanol was added at volume fractions of 5% and 10% while the volume fraction of nano particles was maintained constant at 50 ppm in all test cases. Load was applied on the engine from 0 to 100% using an eddy current dynamometer and the measurements were made at an interval of 20% of load. The measurement results showed that operation of the test engine using 10% ethanol and 50 ppm of ZnO nanoparticles has improved the performance and combustion characteristics that resulted in improved thermal efficiency and reduced emissions from the test engine.
