ENHANCING THE QUALITY OF BAJAJ PULSAR 150CC IC ENGINE CONNECTING ROD THROUGH THE STUDY OF STRAIGHT LINES AND CURVES

Abstract

This project mainly deals with the design and analysis of I.C engine connecting rod.
Connecting Rod 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. For this project, there are two basic
requirements. The first requirement is to design of a model of I.C engine connecting rod as per the
standard mathematical calculations. The second requirement is to analyze of I.C engine 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
Connecting rod is designed; analyzed and has been studied. Connecting Rod temperature has
considerable influence on efficiency, emission, performance of the engine. Purpose of the investigation
is measurement of connecting rod transient temperature at several points on the connecting rod, 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 different aspects of Materials like
Magnesium Alloy, Beryllium 25 Alloy and Forged Steel Materials to cover the research gaps to present
the results based on the systematic studies through the connecting rod of the engine, FEA analysis of is
to measure temperature at the points where it is not possible to find out practically and to observe the
heat flow inside the Connecting Rod.
