How the engine piston work?

The top of the piston is mainly used to process the combustion chamber and reserve a certain space for the valve. Its shape is related to the shape of the combustion chamber and the compression ratio. At present, most gasoline engines use flat-top pistons, which are simple to process and have a small heating area. For gasoline engines that want to adjust the compression ratio, concave or convex top pistons can be used appropriately. For diesel engines, in order to better promote combustion and form a secondary turbine, the piston crown is usually made into a specific shape.
