Cylinder
Cylinder On an internal combustion engine, a cylinder is the space in which the combustion takes place. It also houses the piston and connecting rod. By looking at an engine's cylinder block, you can tell what kind of engine the car has. If the cylinders are in a straight line, it's an inline engine. If there are two rows of cylinders facing each other at an angle, it's a V engine. It the cylinders are in two rows, but lying flat across from each other, it's a horizontally opposed or boxer engine. The number of cylinders, as well as their layout, tells you if the engine is an inline four, V8 or another type. Cylinders are also sometimes called bores
