ECM1101 P13, PSSD1
Disassembly and assembly of a simple four-stroke engine
Mechanics, thermodynamics and strength of materials
Aim
This exercise is designed to show you how a simple four-stroke engine
is constructed and how it operates. You will also have to answer questions
about the engine. These questions relate to topics which you will encounter
in the core courses, such as measurement, thermodynamics, and materials.
Handout and Report
It will be advantageous if you read the questions in the handout and
prepare some of them in advance.
You will have to submit a report answering the questions at the begining of the 2nd year (counting 10% of PSSD2). This
report will be judged on the quality of the answers, of course, but also
on its neatness.

Engines
You may like to look at the Howstuffworks page on engines.
Or at the Java applets created by Klaus Wetzstein.
Finally, NASA has a very interesting series of animations illustrating a four-stroke engine
Thermodynamics
Nasa again has a simple page on the Otto Cycle
that underpins the four-stroke engine.
You can also look at related Carnot Cycle.
