Do you know how your car engine actually works?
Impress others with your understanding of how your car engine actually makes your car move, it’s actually fairly simple!
The purpose of a petrol car engine is to convert fuel into motion, so that your car can move. This is done by igniting petrol inside a small space – converting it into gas. As the fuel is converted into gas it expands and tries to force its way out.
So the ‘combustion engine’ as it known creates a system to do exactly this, however it captures the force of this reaction and turns it into movement.
Simplifying it down into four steps:
STEP 1:
The first step would be injecting the fuel into the cylinder. This can be seen as the piston descends and pulls air through the intake port.
STEP 2:
The mixture of fuel and air is then compressed together as the piston comes back up. The reason for this is that a compressed mixture of these two causes a more explosive reaction when ignited.
STEP 3:
The spark plugs create a small flame inside the cylinder. This ignites the fuel and air mixture and pushes the piston back down.
STEP 4:
The gaseous mixture that has formed as a result of this reaction is then pushed out of the exhaust port as the piston comes back up.
This process within the car engine – repeatedly pushes the piston up and down, creating movement. All there is left to do is convert the piston’s up and down movement into moving a car in the direction desired!
This is done by attaching the bottom of the piston to a connecting rod. The connecting rod would then be connected to the propellor shaft, which is then connected to the rear axle. All these parts moving eventually results in the wheels of your car turning, making your car move forward!
