Hello. For my school project, I will be explaining how a car runs. I have a pretty solid idea but it would be nice to be sure. You don't have to go into serious details, just a general overview.
ToyotaGrl is spot on for any 4-stroke internal combustion engine.
Intake stroke: (pulls air-fuel in), Compression stroke: (compress air-fuel mixture), Power stroke: (ignites compressed air-fuel and forces pistons downward (because the explosion cannot go out the sides or top), Exhaust stroke: (pushes (expels) the burnt gasses out into the exhaust manifold to the exhaust pipe.
Here are two good examples (4Cyl and 8Cyl). Watch the 4Cyl example first then the V8 Example for more details. BTW, I used to have a similar "demonstration car" as shown within the video in my High School auto-shop class but it was an all metal real car engine & drive train (transmission) and chassis cut-away (no plastic).
Also, the principle of the 4-Stroke engine is the same for all 4-stroke engines (no matter how old or new or how many cylinders (1Cyl Lawn Mower, in-line 2,3,4,6,8,10, V6, V8, V10, V12 or Radial engine, etc.)) which is why it helps to learn about the "old school engines" principles as everything else is based upon those principles (even fuel injection Vs carburetor). What's new is old and what's old is new.

8-Cylinder Example:
@Nick1234 How do you think it runs? How would you explain it with the knowledge you have right now?
Unlike Usain Bolt, a vehicle doesn’t need to run. It’s powered by some form of propulsion.
For a conventional vehicle,
1. You fill in fuel & oil
2. Magic happens inside the engine bay
3. You enjoy the g-forces pushing you back into the seat when you stomp on the accelerator.
4. 1, 2 & 3 repeats constantly.
5. The end
