Compression Ratio Calculator

What is a Compression Ratio Calculator?

A compression ratio calculator helps you calculate the compression ratio of an engine, which is the ratio between the cylinder volume at the bottom of the piston’s stroke and the cylinder volume at the top of the stroke. This ratio is crucial for determining engine efficiency.

What is the Compression Ratio?

The compression ratio is the ratio of the volume of the cylinder when the piston is at the bottom of its stroke (BDC) to the volume when it is at the top of its stroke (TDC). A higher compression ratio generally means more engine power and efficiency.

What is the Formula for Compression Ratio?

The formula for compression ratio is:

Compression Ratio (CR) = (V_E + V_C) / V_C

How to Use Compression Ratio Calculator?

To use the compression ratio calculator, simply input the volumes at the top and bottom of the stroke (V_C and V_E), and the calculator will provide the resulting compression ratio. This is essential for understanding engine performance.

Advantages of Using a Compression Ratio Calculator:

• Helps optimize engine efficiency.
• Simple and quick calculation method.
• Ensures accurate results for engine design and modification.

Disadvantages of Using a Compression Ratio Calculator:

• Requires accurate input values for precise results.
• Does not account for all engine dynamics.
