Parts and Their Functions:

It is important to note that many more parts exist to increase effeceincy and depending on what the engine is designed to accomplish. 

• Crankshaft

• Connecting rod

• Camshafts

• Valves (in a two stroke engine there is no valve system just an exhaust outlet and fuel inlet)

• Cylinders

• Spark Plugs

• Piston 

• Crankpin

Types of Valves:

• -Inlet valves: let air and fuel into the combustion chamber.

       -Outlet valves: allow exhaust gases out of the engine.

Exhaust systems: manage gas from the combustion system.

Crankpin: bearing on the crankshaft to help turn linear motion to rotational motion

Camshaft: lobes on the camshaft open and close the intake and exhaust valve in time with the piston to help increase the effeciency of the engine. They are not in all internal combustion engines.

Connecting rod: it is the link between the pistons and the crankshaft, it is important to note that not all engines require rotational motion so a different part may exist to get the desired type of motion.

Cooling system: so lubricants do not degrade and the engine doesnt fail usually use a liquid cooling or air cooling system to cool the engine down. 

Piston: located in the cylinder and is made gas tight by piston rings, it transfers force from expanding gas in the cylinder to the crankshaft with the piston rod or connecting rod. This is where the magic happens the gas expands in the cylinder pushing the piston up. Not all have cylinders but all have a chamber for fuel go into to expand. 

Crankshaft: converts linear motion of the piston to rotational motion.

Flywheel: wheel attached to the crank that forms an intertial mass that helps smooth out the power delivery in each stroke. They also help mount a gear ring for a starter. The flywheel also helps smooth the idle, when your car is not moving but the engine is still on. Flywheels can also be used to mount a clutch or a torque converter.

Starter systems: some use a starter motor powered by the battery or a spark plug.

Heat shielding systems: basically help the cooling system keep the engine at a desired temperature.
