In this unit you will learn about the internal combustion engine in depth through an interactive activity as well as the website content. We will discuss the history, terminology, components, processes, and more. Use the content on this page in order deepen your understanding of the engine and to interact with the activity to demonstrate your learning.
Upon completion of this unit you should be able to:
- Identify the components of an engine
- Understand the responsibility of each component
- Describe the process of power production
- Disassemble and reassemble an engine according to manufacture specification
This unit will be broken down into three components. In order to assess your understanding for this unit, you must complete the following:
- Interactive Engine Activity (5% of Assignments grade)
- The Engine Quiz Part 1 Theory (5% of Quizzes/Tests grade)
- The Engine Quiz Part 2 Lab (10% of Labs grade)
Total: 20% of final grade
Complete the interactive Engine Activity below before proceeding with quiz part 1 and part 2.
The 4 Stroke Cycle
Understanding the process and cycles of a 4 stroke engine are crucial in being able to understand an engine and it’s components. Power occurs through the 4 stroke process as follows:
Make sure you understand this cycle before proceeding to the quizzes and labs. The greater the understanding of this cycle the easier the disassembly and reassembly process will be!
Although the 4 stroke engine is the most common, there are other types of internal combustion engines.
