What is Bore To Stroke Ratio?

The bore to stroke ratio is a measure of the relationship between the diameter of the cylinder bore and the length of the piston stroke in an engine. This ratio is important in engine design as it affects the engine's performance characteristics, such as power output, efficiency, and torque.

Example Calculation 1

Let's assume the following values:

Using the formula:

\[ \text{BTS} = \frac{4}{3} \approx 1.33 \]

The bore to stroke ratio is approximately 1.33.

Example Calculation 2

Let's assume the following values:

Using the formula:

\[ \text{BTS} = \frac{3.5}{4} = 0.875 \]

The bore to stroke ratio is 0.875.
