Improving service life of I.C engine, Heat Flux, Thermal Conductivity, Equivalent stress, Cylinder liner coating.Abstract
Now a days various methods are in use on cylinder piston group for improving service life and performance of
I.C Engine .In this study is to design and coupled field analysis of a dry cylinder liner with respect to piston, piston rings for
Diesel engine . As the performance of cylinder liner mainly depends on the design and material selected for manufacturing
it. Developed a MATLAB code for design calculations to piston, piston rings, cylinder liner (coated/uncoated) by taking input
parameters like Atmospheric and working pressures, Brake power, Engine speed, Thermal conductivity of different materials
Greycastiron, Carbon steel and NiCrAl, A (coating materials).To obtain output as Heatflux and Dimensions required to
draw a model in CATIA software. Coupled field analysis done in FEA to obtain Heat flux, Temperature gradient,
Equivalent stress, Deformation for the materials. Comparing the results will be recommend the best optimized material for
the cylinder liner and also best coated material to be applied on the cylinder liner.
