Hi, young learners! Welcome back to Primary 5 Basic Science and Technology. In our previous lesson, we learned about the definition, identification, and location of vehicle internal parts. You can review that lesson here. Today, we’re going to learn about the Function of Vehicle Internal Parts.
Objectives
By the end of this lesson, you should be able to:
- Identify the function of different vehicle internal parts.
- Explain how each part contributes to the overall operation of a vehicle.
- Show interest and appreciation for how vehicle parts work together.
Vehicle Internal Parts
Understanding the internal parts of a vehicle is essential for recognizing how vehicles function. There are many important vehicle internal parts, and each one plays a crucial role in keeping the vehicle running smoothly.
What is the Function of Vehicle Internal Parts?
The function of vehicle internal parts is to work together to convert fuel into energy that moves the vehicle. Each part has a specific job, and they all rely on each other to do their work.
Some of the Major Vehicle Internal Parts and Their Functions Include:
- Engine: The engine is the heart of the vehicle. It’s responsible for converting fuel into mechanical energy, which powers the vehicle’s movement. Think of it like the engine of a bicycle, which turns the pedals into movement.
- Transmission: The transmission system transmits the power generated by the engine to the wheels. It allows the vehicle to move at different speeds, like shifting gears on a bicycle.
- Radiator: The radiator is responsible for cooling the engine. It does this by transferring heat from the engine’s coolant to the air. Imagine it like a cooling system for the engine, preventing it from overheating.
- Battery: The battery provides electrical power to start the engine and powers the vehicle’s electrical components. It’s like a rechargeable power source for the vehicle.
- Alternator: The alternator charges the battery while the engine is running and powers the electrical system. It’s like a generator that keeps the battery charged.
- Fuel Tank: The fuel tank stores the fuel that the engine uses. It’s like a container that holds the fuel for the vehicle.
- Exhaust System: The exhaust system directs exhaust gases away from the engine and reduces emissions. It’s like a pipe that carries away the waste gases from the engine.
Evaluation Questions
Now that you’ve learned about the function of vehicle internal parts, let’s see if you can answer these questions:
- What is the main function of the engine in a vehicle?
- How does the transmission system help a vehicle move at different speeds?
- Why is the radiator important for the engine’s performance?
- What are the two main functions of the battery in a vehicle?
- Explain how the alternator works to keep the vehicle’s electrical system running.
Conclusion
Today, we learned about the function of vehicle internal parts and how they work together to power a vehicle. Remember that each part plays a vital role in keeping the vehicle running smoothly.
