What is an engine cc?

Engine cylinder volume or capacity is called engine cc. However, this does not indicate the total volume of the engine cylinder. 

engine cc means the volume of the cylinder between the top dead center (TDC) and the bottom dead center (BDC).

The highest position inside the cylinder where the piston can reach is called the top dead center. 

Similarly, the lowest position inside the cylinder where the piston can reach is called the bottom dead center.

The distance between TDC and BDC is called the stroke. The cylinder volume in this area (Stroke) is called the swept volume or stroke volume. 

Actually, this stroke volume is calculated as engine cc. This is also called engine displacement.

In the above picture, you can see an area above the TDC. This is the place where the ignition of fuel takes place. The volume of this area is called the clearance volume.

How to calculate engine cc?

We can calculate the engine cc if know the stroke length and the diameter of the cylinder. The cylinder diameter is also known as the bore diameter.

If the bore diameter is denoted by "d" and the stroke length is denoted by "l"

Calculating the engine cc using this equation,
                                                           
                                                                          π÷4×d²×l

If for a multi-cylinder engine, multiply this by the number of cylinders.

cc or cubic centimeter is a unit of volume. Generally, the engine cc is calculated in three units (CC or cm3, Cubic inches, and liters).

Eg: a 1-liter engine equals 1000 cc
       1.5 liter is 1500 cc
