Design and Analysis of Dry Cylinder Liners Used in Diesel Engines

Abstract

A Cylinder liner is a cylindrical part to be fitted  in to an engine block to form a cylindrical space in which the piston reciprocates very smoothly. It is one of the most important functional parts to make up the interior of an engine. Generally cylinder liners are made of Cast Iron, Cast steel, Nickel CI, Nickel chrome CI. The aim of this project is to design and analyze a dry cylinder liner for Hino-X diesel engines. A Hino – X engine cylinder dry liner used in one of Ashok Leyland model manufactured by  The amount of heat generated, heat transfer rate of the component, temperature produced inside the cylinder are to be calculated using ANSYS analysis package. Various surface coatings like ceramic, aluminum alloys and Nickel chrome alloy steel are used to study the, heat flux, , thermal stresses, thermal displacement, thermal gradient ,nodal temperatures of the cylinder liner. Modeling is done in Pro/Engineer and analysis is done coupled field analysis in ansys. After comparing the results, the best coated cylinder dry liner for this type of diesel engine can be suggested.
