How Does A PISTON Engine Works ?

How are you F1 fans?

Today, let's see what I have brought for those of you who want to learn about engines.

Today we're talking about how a piston engine works.

Let's Start!

So first you need to know that most piston engines have 4 cycles. It's called a 4-stroke cycle.

Let's Learn About Them One by one.

1.Intake

Intake means getting air into the piston.

And Top of the piston there are normally 4 valves.2 for Intake and 2 for Exhaust. We’ll talk about that later in this article. For now

INTAKE Valves – Get air into the piston

EXHAUST Valves - Release the hot air, burned gases out of the cylinder

2.Compression

Then, after the piston takes in air, it comes back up(We'll find out later how this comes up. For now, just remember). But all four valves I mentioned earlier are closed. So now you have to understand that the pressure inside the piston increases and that air heats up.

This is called Compression

3.Power Stroke

Now you need to remember one more thing. This is when you need fuel and a little electricity. 🔥🧨

The two come together to create a small spark. Because there is fuel, the pressure there increases, and the piston goes down again.

3.Exhaust

During this stroke, the piston returns to the top, just like on the compression stroke. But now the exhaust valves are open. The burned air and gases are released from the piston.

I know you have a problem now.

How does the piston go down on the intake stroke, up on the compression stroke, and up on the exhaust stroke? You know how the piston goes down on the power stroke, but what about the others?

Remember this point - There is not just one piston in the engine. There are at least 4 pistons.

Look at this picture. I can simply explain it as – When one piston goes down, the other comes up. When one piston is on the power (fire) stroke, the other piston is on the exhaust stroke. This happens because they are connected to the same crankshaft (rotating shaft).
