Study Notes

Envelopes and sleeves form the cylinder of an engine.
Sleeves are the walls of the combustion chamber and are subject to high wear.
There are two main types of removable sleeves: wet and dry.
Removable sleeves allow for easier maintenance and reduce costs.
Sleeves must resist the pressure of the cooling water circuit and allow for laminar flow.
Wet sleeves have difficulty cooling the upper part, but tangential boring has improved this.
Cavitation erosion of the sleeve's external surface can be minimized with water treatment, special coatings, or a tighter piston-sleeve clearance.
Sleeves must be made of appropriate materials to withstand wear and tear.
Sleeves play a role in controlling lubrication and act as "intake and exhaust valves" in 2-stroke engines.
Removable sleeves can reduce the size and complexity of cylinder blocks.
