Calculate Dynamic Compression Ratio



Formula

The formula to calculate Dynamic Compression Ratio is:

\[ DCR = \frac{IVC}{TDC} \]

What is Dynamic Compression Ratio?

Dynamic Compression Ratio is a measure used in internal combustion engines to compare the volume of the combustion chamber at the point of intake valve closure (IVC) to the volume at top dead center (TDC). It provides a more accurate representation of the engine's compression ratio under actual operating conditions.

Example Calculation 1

Let's assume the following values:

Using the formula:

\[ DCR = \frac{500}{50} = 10 \]

The Dynamic Compression Ratio is 10.

Example Calculation 2

Let's assume the following values:

Using the formula:

\[ DCR = \frac{600}{60} = 10 \]

The Dynamic Compression Ratio is 10.
