In that engine there are 3 pistons: 1 big, semi-circled, down, AND 2 small ones on the top.
My questions:
-What makes the big piston move down? The petrol that is entering? Or does it keep moving up and down by itself? If by itself, then where does the energy to move it come from? From the battery?
What makes it move up?
-Same questions to the 2 small pistons on the top: what makes them move up and down? The battery?
-Where does the petrol go after exploding there?
-Where does the energy that is trapped with the petrol go? Does it turn into heat and just it, perhaps?
Thanks in advance for any help. :)

There is only ONE piston in that video. where do you see three?
Perhaps you are confused with the two VALVES at the top. They are not pistons, they are valves.
The piston moves down due to the force of the exploding fuel. It moves up due to inertial, there is a flywheel that keeps things moving.
The valves are moved via a mechanical linkage to the rotating shaft at the bottom. Linkage not shown.
The petrol, after it explodes, is no longer petrol (actually it is diesel fuel), it is a mixture of nitrogen, carbon dioxide, and water vapor.
The energy in the diesel fuel causes the explosions, which cause the piston to move up and down. That is transferred to the drive shaft and from there to the drive wheels.
Use your brain. If the energy in the fuel just resulted in heat, how would you get any useful work out of the engine?
