How it works?
The internal combustion engine works by means of mini controlled explosions in a chamber full of compressed fuel & air mixture.
There are four key stages of the engine sequence.
1 - Intake - in this phase, the intake valve opens and chamber is filled in with a mixture of fuel and air.
2- Compression - the fuel & air mixture is compressed which then increases the temperature
3 - Power - The spark plug sitting on the top of the combustion chamber ignites this hot fuel and air mixture, causing an explosion in the combusiton chamber.
This mini-controlled explosion produces a great force that pushes the piston down, hence turning the crankshaft. This will then transmit the force to drive external loads (do work).
4 - Exhaust - The final stage in the engine cycle is the exhaust stage where the exhaust valve opens and the exhaust from the burnt fuel is then pushed out of the combusiton chamber.
