DESIGN AND ANALYSIS OF I.C ENGINE PISTON, PISTON RINGS AND CONNECTING ROD

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.
