## About Compression Ratio Calculator (Formula)

The Compression Ratio Calculator is a tool used to determine the compression ratio of an internal combustion engine. The compression ratio represents the ratio of the maximum volume to the minimum volume inside the engine’s combustion chamber. It is an important parameter that affects engine performance, efficiency, and power output. The formula for calculating the compression ratio can be expressed as:

**Compression Ratio = (Cylinder Volume + Combustion Chamber Volume) / Combustion Chamber Volume**

Here’s a breakdown of the components involved in the formula:

- Compression Ratio: The compression ratio is the ratio of the total volume inside the engine cylinder (including the combustion chamber) at the bottom dead center (BDC) position to the volume of the combustion chamber at the top dead center (TDC) position.
- Cylinder Volume: The cylinder volume represents the total volume of the engine cylinder, including the clearance volume and the swept volume. It can be calculated by multiplying the cross-sectional area of the cylinder by the stroke length.
- Combustion Chamber Volume: The combustion chamber volume refers to the volume of the combustion chamber when the piston is at the top dead center (TDC) position. It includes the space above the piston and any additional volume due to the shape and design of the combustion chamber.

By adding the cylinder volume to the combustion chamber volume and dividing it by the combustion chamber volume, the compression ratio of the engine can be determined. The compression ratio is typically expressed as a numerical value (e.g., 10:1 or 12:1).
