Abstract

Thermal stresses due to long running of spark ignition engine often results in wear and tear of cylinder near the top dead center (TDC). These high thermal stresses at TDC arise due to the high temperature gradient during spark ignition. This situation eventually decreases the life and efficiency of an engine. In this study, the numerical and analytical analysis was carried out on 1298 cc in line four stroke spark ignition (SI) engine having a power output of 63 kW to drop the peak temperature at TDC. to reduce the peak value of temperature, square pin fins were used on the surface of engine cylinder wall near TDC. A parametric study is performed to get an optimal solution for removal of the peak temperature load at TDC. The results showed that the fins with dimension of 4 × 4 × 4 m m 3 along with uniform spacing of 2 mm provide the optimum solution. It has been observed that the peak temperature at TDC dropped down considerably from 160 °C to 133 °C (a percentage reduction of 16.87%) for the pin fins case as compared to without the fin case. Furthermore, the heat transfer effectiveness for the optimum case was calculated as 3.32, whereas for numerical and analytical study it was calculated as 3.43. The error recorded between both the values was limited to 3.2%.
