MID (Modular Integrated Deck) Wet Sleeves by Darton

Many production cast iron and aluminum blocks suffer from a design weakness of cylinder stability by nature of poor support at the upper deck area. Darton has engineered a superior patented (patent #6,799,541) solution by using a unique designed cylinder sleeve which when siamesed and nested, creates a solid deck of sleeve flanges held in tension, reinforcing the upper deck area and provides for individual replacement with what we call Modular Integrated Deck (MID).

Darton designs manage and enhance water flow from block to head to promote stability of cooling and all sleeves are of the "Wet" design. The enhanced water flow in and around the flange area is possible because of ported water flow control engineering we call "Swirl Coolant Technology™". This process begins with specific engineering models of respective cylinder head and combustion chamber designs and then we promote increased flow of water in those areas of the upper sleeve area subjected to the most heat. Heat is also dissipated through the use of " Register Fins"™. There is a different engineering model for each engine and cylinder design.

High RPM normally translates into efficient scavenging of airflow but during misfires or incomplete flame propagation, high cylinder pressures and temperatures are created. Our MID™ design compensates for this high resident heat soak condition. With Darton's "MID", Swirl Coolant Technology the cooling medium is ported and directed to significantly improve heat transfer where it is needed most, in the upper cylinder wall/flange area.

Now that Darton has solved the design issue of cylinder weakness another issue with wet sleeves is the sleeves exterior surface. In a standard wet sleeve design sleeves are punished by turbulent coolant often causing corrosion or rust. Darton now supplies the MID sleeves with a phosphate coating. Phosphate coating is the treatment with a solution whereby the surface of the metal is covered with an integral, protective layer of insoluble crystalline. This microcrystalline structure on the MID sleeve makes it optimal for corrosion and rust resistance. Adding the phosphate coating to the MID sleeve is just another way Darton is constantly evolving sleeve design and the way the industry perceives the way you can sleeve a block.
