The piston ring groove serves as a seating area for piston rings within an engine's piston. Its primary function is to maintain a seal between the piston and the cylinder wall, preventing the escape of combustion gases and controlling oil consumption. Additionally, the groove allows for axial movement of the rings, accommodating thermal expansion and ensuring proper ring function during engine operation. Proper design and maintenance of the groove are essential for optimal engine performance and longevity.
Yes, a groove will decrease the effective diameter of the drum, but not by twice the depth of the groove. Instead, the reduction in diameter is equal to the depth of the groove, which is subtracted from the original diameter. Therefore, the overall decrease in diameter is exactly equal to the depth of the groove, not doubled.

Krush Groove was created in 1984.
I can't tell for sure because I haven't been able to find a clear enough close-up, but it bears a striking resemblance to the class ring of Texas A&M University. The clearest shot I've been able to find of her ring appears to show the same shield crest in the center and the cannon/rifle/sabre emblem on the side of the ring. The groove running around the edges of the ring is identical to the edge found on an Aggie ring.
Feel the Groove was created in 1991-01.
one ring per piston, the pistons have a groove in it where the ring fits on.

As the piston moves up and down in the cylinder it also moves the piston rings up and down in the grooves. With the rings moving up and down it gradually increases the side clearence. Material is taken off from both the piston groove and the ring.
assuming that you have new cylinder liners and pistons or old pistons with good ring groove conditions, piston rings come with the correct/specified clearance when bought new.
There is a special tool for this purpose. Should be able to buy it or rent it at your local auto parts store.
Prevents wear on the pistin and reduces compression loss
The standard gap of a piston ring refers to the spacing between the ends of the ring when it is installed in the cylinder. This gap is crucial for proper engine function, as it allows for thermal expansion and prevents the ring from binding in the groove. Typically, the gap varies depending on the engine type and application, but it generally ranges from 0.015 to 0.040 inches for most internal combustion engines. Proper measurement and adjustment of this gap ensure optimal sealing and engine performance.
The three main functions of piston rings in reciprocating engines are:Sealing the combustion/expansion chamber.Supporting heat transfer from the piston to the cylinder wall.Regulating engine oil consumption.
To prevent oil getting by the oil ring and compression past the others. Also, if they were in line, it would tend to make a groove in the cylinder wall.
You have to disassemble the entire engine, remove the piston and check the rubber ring around that piston.
The DNJ ring spec. information, printed on each compression ring (located next to the piston ring gap), is installed facing the top of the piston for both the top (#1) and middle (#2) compression piston ring slots. The oil control ring can be installed just like any other oil control ring in the bottom (#3) piston ring slot.
