Abstract

This paper is to determine the
temperature and the stress distributions in a
partial ceramic coated spark ignition (SI)
engine piston and reduce the mass of the
piston for improving engine operating
parameters. Our aim of this paper is to
determine the temperature and the stress
distributions in a partial ceramic coated
spark ignition (SI) engine piston. Effects of
coating thickness and width on temperature
and stress distributions were investigated
including comparisons with results from an
uncoated piston.This paper is to determine the

and stress distributions were investigated

uncoated piston. Thermal analysis is
investigated on a conventional (uncoated) SI
engine piston, made of Al-Si alloy and steel.
Secondly, thermal analysis is performed on
piston, coated with MgO-ZrO2 material by
means of using a commercial code, namely
ANSYS. Finally, the results of different
pistons will be compared. The effects of
coatings on the thermal behavior of the
piston are to be investigated and improved.
