Cars are amazing machines. They take us places every day. But, have you ever wondered how they work? One important part of a car is the exhaust manifold. It plays a big role in the engine. Let’s learn more about it.
What is an Exhaust Manifold?
The exhaust manifold is part of the car’s engine. It collects gases from the engine. Then, it sends them to the exhaust pipe. This is how it works:
- The engine burns fuel to make power.
- Burning fuel makes gases.
- The exhaust manifold gathers these gases.
- Then, it sends them out of the car.
The manifold is usually made of metal. It can handle high heat. This is important because the gases are very hot.
