A gasoline engine, also known as a gasoline engine, is a type of internal combustion engine that uses gasoline as fuel to produce mechanical energy. Here is a basic description of how a gasoline engine works:

1. Intake stroke: The engine draws air and gasoline into the cylinder by moving the piston downwards and creating a vacuum. The inlet valve opens, allowing the air-petrol mixture to flow into the combustion chamber.
2. Compression stroke: Once the piston has reached the bottom of its travel, the valves close and the piston begins to move upward again. The air-petrol mixture is compressed in the cylinder.
3. Work cycle: Shortly before the piston reaches the upper end of its movement, the spark plug ignites the compressed air-gasoline mixture, which then burns explosively. The resulting hot gases expand and push the piston down with great force, causing the crankshaft to move and generating mechanical energy.
4. Exhaust stroke: After the piston has reached the bottom point of its movement, the exhaust valve opens. The piston moves up again and pushes the burned gases (exhaust gases) out of the cylinder and into the exhaust.

This process repeats itself several times per second in each cylinder of the engine and powers the vehicle. Gasoline engines can have different designs depending on the number of cylinders and the arrangement of the cylinders, e.g. E.g. in-line, V or boxer engines.
