Design and Validation of 220cc Oil Cooled Engine Cylinder and Cylinder Head

Abstract

A cylinder head is made of box type of section of considerable depth to accommodate

ports of air and gas passages, inlet valve, exhaust valve and spark plug. The studs or bolts are

screwed up tightly along with a metal gasket or asbestos packing to provide a leak proof joint

between the cylinder and cylinder head. The cylinder head is subjected to temperatures due to

combustion in cylinder and pressure on surface.

Optimal Design means the best of all feasible designs proposed in phase one , i.e., the

conceptual design. Optimization is the processes of maximizing a desired quantity or

minimizing an undesired one. Optimization theory is the body of mathematics that deals with

the properties of maxima and minima, and how to find maxima and minima numerically.

These optimization are done by the following methods,

1. Optimization by Evaluation

2. Optimization by Trial-and-Error Modeling

3. Optimization by Numerical Algorithm

4. Optimization by Parameters

5. Optimization by Material
