1. Seal for coolant
. Support point for liner
The inside of the cylinder liner is machined by what is known as plateau honing. This type of machining leaves a
fine pattern of grooves which ensures that the oil needed for lubrication between piston rings and liner remains
on the wall of the liner.
The design of the pattern is of major importance for ensuring low oil consumption in the engine.
Two sealing rings, one in the block and one in the liner, seal off the coolant jacket. The surface of the liner in
contact with the liner shelf seals off the lubricating oil.
In the space between liner shelf and sealing ring in the block is an overflow hole which discharges in the side of
the cylinder block under the side covers.
Leakage at any of the sealing surfaces will result in oil or coolant coming out of the overflow hole.
