The video is about building a V8 engine, a miniature electromagnetic engine that works similarly to a car engine. The creators had promised to build this engine if their previous video got over 100,000 views, which it did. The video explains the process of building the engine, including creating the crankshaft, assembling the engine, and installing the coils or electromagnets. The creators also explain the electrical part of the engine, including how the electromagnets work and how they are connected. They compare the miniature engine to a real car engine, explaining the similarities and differences. The video also mentions the importance of cleaning and lubrication in improving engine performance, and how using a fuel with additives, such as the new Shell V-Power, can make a difference. The creators then test the engine with an Opel car battery and measure its revolutions per minute, which reaches 250 rpm. They conclude that the engine's performance can be improved with cleaning and lubrication, and that using a fuel with additives can make a difference.
Here are the key facts extracted from the text:
1. The V8 engine has eight cylinders.
2. The engine is being sponsored by Shell's new V-Power.
3. The crankshaft is the most complicated part of the V8 engine.
4. The crankshaft was made from a copper wire with a maximum diameter of three and a half millimeters.
5. The crankshaft has eight parts that resemble a crank.
6. The engine has a structure to support it, with measurements provided in the video description.
7. The engine uses an electromagnetic motor.
8. The motor has two terminals, one positive and one negative.
9. The engine uses a system of switches to connect the coils.
10. The engine is similar to a car engine, with parts that can be compared to a combustion engine.
11. The engine has a flywheel and a connecting rod.
12. The engine uses an electromagnet to control the flow of "gasoline".
13. The engine was tested with a computer source, but didn't work, so it was tested with an Opel car battery instead.
14. The engine's performance can be improved with cleaning and lubrication.
15. The engine's performance can be compared to a combustion engine.
16. The engine uses oil to lubricate the parts and reduce friction.
17. The engine's performance can be improved with the use of fuel with additives.
18. Shell's new V-Power gasoline has additives that can help clean and lubricate the engine.
