How does a engine work ?​

Answer 1

Answer:

An engine or motor is a machine designed to convert one form of energy into mechanical energy. Heat engines, like the internal combustion engine, burn a fuel to create heat which is then used to do work.

The engine then partially converts the energy from the combustion to work. The engine consists of a fixed cylinder and a moving piston. ... After the piston compresses the fuel-air mixture, the spark ignites it, causing combustion. The expansion of the combustion gases pushes the piston during the power stroke
