Abstract
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.
Highlights
The results showed that copper coated piston and combustion chamber engine reduces hydro carbon (HC) and carbon monoxide (CO) emissions
The results showed that that the thermal barrier coatings exhibit higher porosity[12]
The experiments were conducted for the diesel and biodiesel B10, B20 on a coated piston engine and Table 6 shows engine performance results obtained through the experiments
Summary
The main aim of the paper is to minimize the major diesel engine emissions like CO and HC
