Cylinders contain the moving pistons mentioned above, and almost all modern engines have at least two. The arrangement of these cylinders contributes to different advantages and disadvantages, costs, and performance. Some arrangements are better suited for specific vehicles than others.

As seen in the 4-stroke process, the spark plug ignites the air and fuel mixture, creating combustion, which harnesses the fuel mixture as mechanical energy. This process happens hundreds of times per minute to keep the engine running.

The intake valve opens when pushing air and fuel into the chamber. The exhaust valve opens when expelling exhaust gases after combustion. During the compression and combustion strokes, both values are closed, sealing the chamber to ensure proper pressure.

Pistons are metal components that move within the cylinder. Piston rings create a seal to prevent fuel, air, and exhaust from entering the oil sump. As these rings wear out, the seal weakens and the engine may begin to burn more oil.

The connecting rod links the piston to the crankshaft, transferring motion between the two.

The crankshaft acts like the arm of a jack-in-the-box—its rotation drives the piston in a circular motion throughout the combustion process.

The oil sump holds engine oil at the bottom of the engine. This oil lubricates moving parts and prevents metal-on-metal contact between the crankshaft and the engine block.
