SHS2 Applied Technology · Semester 1 Week 1: Introduction to Engine Technology

Lesson notes

Learning Objectives

Indicator: 2.1.1.LI.1 - Explain engine cooling system and describe the construction and operation of the air-cooling systems

By the end of the lesson, learners can:

Explain the purpose of the engine cooling system and state what happens when an engine overheats or runs too cold.
Identify and describe the two main types of engine cooling systems: air cooling and water (liquid) cooling.
Sketch and label the key components of an air-cooling system on a motor vehicle.
Describe the working principle of an air-cooling system, including how heat is transferred away from the engine.
Discuss the advantages and disadvantages of air-cooled engines based on observation and group analysis.

Exemplars (from the NaCCA curriculum)

Problem based Learning: Learners brainstorm in groups with views tolerated from others, to discuss the exact purpose of cooling system, the two main types and also examine the layout of air-cooling systems on a motor vehicle and present a report for discussions.
Experiential learning: Learners visit a local repair or school workshop to observe the working principle of air-cooled engines
