Lesson Plan for Senior Secondary 2 - Auto Mechanical - Automobile: A Diesel Engine Ii

Lessonplan for teaching Senior Secondary 2 students about "Automobile: A Diesel Engine II" in the Auto Mechanical course. This lesson will build on prior knowledge from Diesel Engine I and further explore the components, operation, and maintenance of diesel engines. ### Lesson Plan: Automobile: A Diesel Engine II #### Grade Level: Senior Secondary 2 (SS2) #### Duration: 90 minutes #### Objectives: By the end of the lesson, students should be able to: 1. Identify and explain the function of advanced components of a diesel engine. 2. Describe the operation of a diesel engine in detail. 3. Perform basic maintenance tasks on a diesel engine. 4. Diagnose common issues in a diesel engine. #### Materials Needed: - Diesel engine model (or a real engine, if available) - Projector and computer for presentations - Handouts with diagrams and notes - Basic tools for engine maintenance (wrenches, screwdrivers, torque wrench) - Safety equipment (gloves, goggles) - Whiteboard and markers #### Lesson Structure: **1. Introduction (10 minutes)** - Recap the basics of diesel engines covered in Diesel Engine I: components, basic operations, and simple maintenance. - Introduce the objectives and outline of today’s lesson. *Discussion Question:* "Can anyone name the main components of a diesel engine we learned last time?" **2. Detailed Components of Diesel Engines (20 minutes)** - Use diagrams and a slideshow to discuss the following components in detail: - Turbocharger - Fuel injection system - Intercooler - Glow plugs - EGR (Exhaust Gas Recirculation) system *Interactive Activity:* Have students label the components on a large diagram of a diesel engine. **3. Explaining Diesel Engine Operation (20 minutes)** - Explain the four-stroke cycle in detail: - Intake - Compression - Power - Exhaust *Demonstration:* Show a video of a four-stroke cycle in slow motion. If a real engine is available, use it to show the movement of parts during each stroke. **4. Maintenance Tasks (20 minutes)** - Detail common maintenance tasks: - Oil change - Fuel filter replacement - Air filter replacement - Checking the coolant *Hands-On Practice:* Divide students into small groups and let them perform one of these tasks on the diesel engine model or real engine, using the provided tools. **5. Diagnosing Common Issues (10 minutes)** - Discuss common issues such as: - Hard starting - Smoke from exhaust - Power loss - Overheating *Case Study:* Present a few common issues and ask students to diagnose the problem and propose a solution. **6. Q&A and Recap (10 minutes)** - Open the floor for questions. - Recap the main points of the lesson. - Hand out a short quiz to assess understanding. #### Assessment: - Participation in discussions and hands-on activities. - Correctly labeling engine components on a diagram. - Performing basic maintenance tasks correctly. - Answers on the short quiz. #### Homework: - Assign students to write a 1-page report on any one component of the diesel engine discussed today, detailing its function and importance. #### Safety Considerations: - Ensure students wear safety goggles and gloves during hands-on activities. - Properly demonstrate the use of tools before allowing students to use them. This lesson plan aims to be interactive, engaging, and practical, ensuring students gain both theoretical knowledge and hands-on experience with diesel engines.
