What does cc stand for in a internal combustion engine?

The "cc" stands for "cubic centimeters". It is a unit of volume used to measure the displacement of an internal combustion engine. Displacement is the total volume swept by all of the pistons in an engine during one complete combustion cycle. It is expressed in cubic centimeters (cc) or liters (L).

For example, a 2.0-liter engine has a displacement of 2000 cc. This means that the total volume swept by all of the pistons in the engine during one complete combustion cycle is 2000 cubic centimeters.

Displacement is an important factor in determining the power and torque of an engine. In general, the larger the displacement, the more power and torque an engine will produce. However, there are other factors that affect power and torque, such as the design of the engine, the fuel used, and the air/fuel mixture.
