How engine works with electricity?

Answer 1

I assume that your question is how you can use an engine to obtain electricity. If so, the idea is the following: You burn a fuel inside the combustion chamber of the engine. What this will do is to convert the chemical energy of the fuel molecules into thermal energy. You can then use some kind of rotor (turbine) that converts this thermal energy into mechanical energy by rotating the turbine. The mechanical energy is transmitted via an axle that connects the turbine to an electric generator. Simplifying, a generator comprises of a magnet that rotates inside a coil and electricity is then generated inside the coil of this generator via induction. That's how you obtain electricity from a combustion engine. I hope I understood your question correctly.
