What are the main parts of a carburetor ICE? What is the difference from a carburetor engine diesel engines have?

The engine consists of a cylinder in which a piston moves, connected by a connecting rod to the crankshaft. A heavy flywheel is mounted on the shaft. In the upper part of the cylinder there are two valves for the intake of a mixture of fuel and air and the release of exhaust gases, and a candle that ignites the combustible mixture. In a diesel engine, the combustible mixture is ignited by compressed air.
