The area of the pistons, how far they travel in the cylinder, and the number of cylinders all come together to tell us how much air the engine is capable of displacing. Ready for some math?

In the video after the break, [Brick Technology] uses LEGO to gain some practical insight into the world of piston engine design, from single-cylinder all the way up to radial twelve-cylinder engines.

The valve for one of the cylinders has its guide exposed, which isn't something you should be seeing. Plus, there's a hunk of piston at the bottom of the engine when the timing cover comes off.

Technically speaking, the portion of the piston that's missing is small, but it doesn't take much to kill an engine. Per the video, it appears the cylinder was running hot enough to melt the piston.

Both pistons and valves move in and out of a space at the top of engine cylinders known as the “combustion chamber”.

Before both components can be put together, rings are added to the pistons. This creates an airtight seal in the engine's cylinder. The piston is placed into a machine that will marry the ...
