How Engines Work

Engines are able to work because of the Pistons inside.  These Pistons use 5 steps to create energy for the engine.  the 5 steps are

1. Intake
-The Pistons take in fuel  through the intake valve

2. Compression
-The fuel is compressed inside the Piston

3.  Ignition
-the fuel ignites causing it to explode

4. Power
-the release in energy from the explosion causes the piston to decompress

5.  Exhaust
-When the piston decompresses an exhaust valve opens where the waste from the explosion is released through that valve.  Also the intake valve reopens and the cycle begins again.
