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.
