What is Ring Gap?

The ring gap is the clearance between the ends of a piston ring when installed in a cylinder bore. It is crucial for ensuring proper engine performance and preventing damage. The ring gap allows for thermal expansion of the piston ring during engine operation.

Example Calculation

Let's assume the following value:

Using the formula to calculate the ring gap:

\[ RG = 4 \cdot 0.004 = 0.016 \text{ inches} \]

The Ring Gap (RG) is 0.016 inches.
