ME217 and XE220 or equivalent

Type of module

Double module delivered over two semesters

Aims

To provide a firm foundation in engine design methods and techniques t
hrough the
introduction of the fundamentals of conduction, convection and radiation heat transfer as
applied to engineering devices and to illustrate the strategies used to meet the needs of
particular engine design goals.

Learning
outcomes/objectives

On
successful completion of the module the student will be able to:



Assess the suitability of the different combustion systems employed in Internal
Combustion Engines by reference to their fundamental operating principles, and explain the
factors affecting th
eir performance.



Understand and apply the methods and techniques used in the engine design process.



Design the major components of a reciprocating internal combustion engine.



Critically assess the approach required to achieve an optimal engine design.



Appr
eciate the principles of modern automotive engine management.



Analyse heat transfer problems involving conduction and convection by application of
the concept of thermal resistance.



Select the appropriate heat exchanger type for an application and evaluate

its
performance by applying the concepts of Log Mean Temperature Difference and Heat
Exchanger Effectiveness (NTU).

Brief description of
module content and/or
aims (maximum 80
words)

This module provides an in
-
depth examination of the design of internal combustion engines.
It examines the constraints on the design of an engine using the princi
ples of engineering
science. Common engine systems are examined to illustrate the application of these design
principles.
