The performance and emission affected by piston catalytic coating have been analyzed in this study. The main contributing factors for improving performance such as load, fuel and speed have been preferred to reduce the emission and improve the performance of an IC engine. These specific standard parameters have been modified with copper alloy coated diesel engine with the aid of design of experiment by Taguchi with grey relational analysis optimization (GRA) method, for improving the IC engine performance and reducing the emissions. The result shows modified copper chromium zirconium (CuCr1Zr) catalytic coated piston produces less emission and improves performance when compared to standard un-coated piston type engine. In this investigation cotton seed oil is used as a bio- diesel and the piston and combustion chamber were coated with copper chromium zirconium material with a thickness of 250 microns. Finally the results of the experiments were compared with un-coated engine and optimized parameters have been identified for catalytic coated modified IC engine using Taguchi with GRA approach.
本文分析了活塞催化涂层对性能和排放的影响。为了降低排放、提高内燃机性能，优选了改善性能的主要因素，如负荷、燃料和转速。借助田口试验设计和灰色关联分析优化（GRA）方法，用铜合金涂层柴油机对这些特定标准参数进行了修正，以提高内燃机性能，减少排放。结果表明，与标准无涂层活塞式发动机相比，改性铜铬锆（CuCr1Zr）催化涂层活塞可减少排放，提高性能。在本研究中，棉籽油被用作生物柴油，活塞和燃烧室采用铜铬锆材料进行了 250 微米厚的涂层处理。最后，将实验结果与无涂层发动机进行了比较，并采用田口与 GRA 方法对催化涂层改性内燃机的优化参数进行了确定。
