Effect of CuO nano additive with novel punnai methyl ester in a TBC CI engine

The requirement for petroleum fuel has amplified due to the growth of automobile industries and population growth. To meet fossil fuel demand in the future, alternative fuel for diesel fuel is necessary. The technique for engine modification is also considered as the latest advance in engine research aimed to complete combustion. The engine has been coated with a mixture of a ceramic thermal barrier material of 88% Yttria Stabilized Zirconia (YSZ), 4% Magnesium oxide (MgO), and 8% Titanium oxide (TiO 2 ) of 150 μ m thickness by the plasma spray process. After engine modification, the coated engine has been analyzed with the mixing of Copper oxide (CuO) nanoadditive to the B20 Punnai Methyl Ester. The structural and chemical constituents of the biofuel are determined using Fourier transform infrared spectroscopy and gas chromatography. The test result noted that brake thermal efficiency is increased by 17.14% for the coated engine as compared to the uncoated engine. The brake specific fuel consumption for the tested fuel used in the coated engine is decreased by 11.16%. Engine emission parameters are reduced especially oxides of nitrogen (NO x ) emission of 10.84% for the tested fuel in the coated engine.
