Effect and Optimization of Performance of Ceramic Coated Internal Combustion Engine

Abstract

Ceramic coating on the internal combustion engine has appeared as one of the great means that increase performance and efficiency of an engine. This paper presents a novel approach for the optimization and study of the effect of performance of ceramic coated internal combustion engine. In this paper, different parameters like engine load and engine speed are optimized with the consideration of various responses such as engine power output, volumetric efficiency, heat transfer rate to coolant and carbon monoxide (CO) emission. Experiments are carried out by varying the parameters of load and engine speed of ceramic coated internal combustion engine. Orthogonal array is taken to conduct the experiments with the load of 40 Nm, 120 Nm, 200 Nm and speed of 1200, 2000 and 2800 in rev/min. This method shows a good convergence with the experimental and optimum process parameters where maximum volumetric efficiency, minimum heat transfer rate and minimum CO emission are obtained by using the grey relational analysis method.
