The Numerical Study on the Effect of CuO Nanoparticle Additive into SI Engine Coolant on the Engine Power 2020-01-2032

The goal of the study was to investigate the effect of different amounts of the CuO nanoparticles used as additive in the coolant on the power and efficiency of the analyzed SI engine. The temperature gradients in the engine body and its components were obtained using the elaborated model of the heat exchange in engine cooled with different fluids. The simplified model of combustion was used to estimate the temperature and power values generated during the combustion process in the engine under given load and speed values. The efficiency of the engine was estimated using the model taking into account various resistances generated during the operation of a given type of engine. The obtained changes in the engine power and efficiency resulted from the changed composition of the engine coolant were presented.
