Design Optimization And Analysis Of A PISTON, PISTON RINGS AND CONNECTING ROD In Internal Combustion Engine Applications

Abstract

This project mainly deals with the design and analysis of I.C engine piston, piston rings and connecting rod. Piston
is a component of reciprocating engines, reciprocating pumps, gas compressors and pneumatic cylinders among
other similar mechanisms. In an engine, its purpose is to transfer force from expanding gas in the cylinder to the
crankshaft via a piston rod or connecting rod. For this project, there are two basic requirements. The first
requirement is to design of a model of I.C engine piston, piston rings and connecting rod. The second requirement
is to analyze of I.C engine piston, piston rings and connecting rod by the method, such as following a track, which
consists of straight lines and curves. These systems are done by modeling software’s like CatiaV5, and analysis is
done by Ansys software. Specifications of a product are detailed in terms of the product size, speed range, weight
and power consumption. Here the piston is designed; analyzed and has been studied. Piston temperature has
considerable influence on efficiency, emission, performance of the engine. Purpose of the investigation is
measurement of piston transient temperature at several points on the piston, from cold start to steady condition and
comparison with the results of finite element analysis. Even though the program worked well, there were some
errors that were identified after testing, resulting in increased performance. In this project work has been taken
up on the following aspects to cover the research gaps to present the results based on the systematic studies. Nodal
Temperature, Thermal Gradient through the piston of the engine, FEA analysis of the piston to measure Thermal
Flux at the points where it is not possible to find out practically and to observe Heat Flow inside the piston.
