บทคัดย่อ: The aim of this research is modification of internal combustion engine for producing power from exhaust gases. Energy is extracted by placing turbine in exhaust gas passage. Two-third of the energy from combustion in a vehicle is lost as waste heat, out of which 40% is in the form of exhaust gases. Turbine was installed in the exhaust passage to generate power which would be utilized to run the electrical accessories of the engine. SOLIDWORKS were used for 3D CAD modeling and flow analysis of turbine with radial inlet-axial outlet. In addition to that ANSYS was used for stress-strain analysis. In addition, research has been carried out to check catalytic activity of catalysts made from salts/metal precursors; Cerium Sulphate Tetra hydrate, Manganese Sulphate Mono hydrate and Copper Sulphate Penta hydrate that are not expensive and could be replaced by the nobel metals as they are very expensive and absolutely not abundant on Earth. Test sample catalysts were prepared through co-precipitation method having different molar concentration and then tested the conversion efficiency by applying the catalysts on ceramic plates by using Flue Gas Analyzer. On basis of results, final catalysts was prepared and applied on monolithic ceramic plate and then tested concerning the resulting conversion rate of pollutants as compared to already installed Catalytic Converter. During the experimentation work it was observed that base metals catalyst have low thermal stability at higher temperature and it adversely altered the performance of the catalyst greatly. Future study can be done to do research on increasing the thermal stability of catalysts with different molar ratios.
