Now you all know about different types of engines. Now let's start with the Internal Combustion engine's first part i.e. PISTON ENGINE.
Piston Engines are be classified further based on engine's cycle.... Ya, in case of Piston engine we have:
But all of them has somewhat same kind of configuration. So before beginning the lesson let's get introduced with the parts it possesses

The spark plug supplies the spark that ignites the air/fuel mixture so that combustion can occur. The spark must occur at right moment so that everything work properly.
Its a cylindrical piece of metal that moves up and down inside the combustion chamber
When the piston is moved up and down, the converts that motion into a circular motion just like a crank on a jack-in-the-box does.
Its opens the space from where the mixture of air/fuel enters and the exhaust exits. Actually two valves are present one for the Intake and the other for Exhaust. Note-That both valves are closed during compression and combustion and therefore the combustion chamber is sealed for middle two stroke.
It connects the piston to the crankshaft. It can rotate at both ends so that its angle can change as the piston moves and the crankshaft rotates.
Its around the crankshaft and oil to lubricate the Connecting rod and the crankshaft.
Here's the original of DI-section of an Internal Combustion Engine:
