Performance and Emissions Parameters Optimization of Thermal Barrier Coated Engine Tested with Tamanu Blended Diesel Fuel: A Novel Emission Pollution-Preventive Approach

<p>Diesel engines cause major pollutants such as hydrocarbons (HC), carbon monoxide (CO), and oxides of nitrogen (NOx). These emissions affect environmental systems lead to global warming climatic change effects. also humans health problems like lung cancer, breathing problems, headaches, etc. Hence, some necessary action has be taken minimise these pollutants. There are several steps available control emissions. The coating the piston using catalytic material is an effective method novel approach reducing in diesel with alternate fuel operated engines. copper-chromium-zirconium alloy (CuCr1Zr) known for its good thermal conductivity catalyst material, coated bycopper-chromium-zirconium 250µm thickness. Tamanu oil was blended a 20% (B20) 40% (B40) ratio used engine. results showed significant reduction improvements performance. In this research, Taguchi grey relational analysis (GRA) optimization technique study effect engine operating parameters on emission level load alloy-coated Based experimental found that most influential factor CO HCexhaust gas reductions type engines.</p>
