Design and analysis of dry cylinder liners of coated and noncoated materials used in diesel engines

A Cylinder liner is a cylindrical part to be fixed in to an engine block to form a cylinder. It is one of the most significant efficient parts to make up the interior of an engine. Aim of the thesis is to design and analysis of a dry liner for diesel engines. The first step is to model the dry liner part by using Pro/Engineer. The dimension of the liner are taken from “Kusalava Industries”, Vijayawada for the engine of Hino – X Ashok Leyland model. In the next step, the amount of heat generated, heat transfer rate of the component, temperature produced inside the cylinder are to be calculated. usually cylinder liners are ended of Cast Iron, Cast steel, Nickel CI, Nickel chrome CI. The surface of the liner is heat treated to obtain hard surface. The foremost aim of the document is to learn the heat transfer rate, heat flux, temperature distribution, thermal stresses, thermal strain, and thermal gradient of the liner by apply boundary circumstances as a temperature produced inside of the cylinder. And also by applying the surface coatings like ceramic, aluminum alloys and Nickel chrome alloy steel. Also we are conducting fatigue analysis on the liners. Fatigue analysis is used for finding the life time of the component means we can find out numeral of cycles it can with stand for the applied loads. By compa re the above results, the desirable type of liner in a diesel engine can be validated. Modeling is ended in Pro/Engineer and analysis is done in ANSYS.
