Ceramic-coated exhausts

[email protected]
The subject of the 'management' of heat as concerns race engine exhausts is largely a matter of containment. We have covered the subject briefly before in RET-Monitor articles, and have discussed the advantages of keeping the heat in the exhaust rather than having it radiated to the outside world via the engine bay, which contains lots of electronic components that can object to becoming too hot. Heat radiated to the engine structure and the gearbox can lead to the need for greater...

Oil-shedding coating applications

[email protected]

In a previous article on oil-shedding coatings in summer 2010, I mentioned some of the reasons why they might yield performance gains in an engine where frictional losses due to the action of oil shearing are significant. These coatings are likely to offer most gain in engines where there is a combination of an excess of oil and a number of areas of small dynamic clearance where shearing takes place. The reality is that, where opportunity exists to engineer a more carefully considered...

Bearing coatings

[email protected]
The preponderance of multi-cylinder four-stroke race engines means that the production and supply of bearing shells is big business. The share of the bearing market occupied by two-stroke and four-stroke engines with assembled crankshafts that use rolling-element main and crankpin bearings, or four-stroke engines that are designed to use special rolling-element bearings with split outer races, is very small indeed. The manufacture of bearings, through the application of better...

Piston skirt coatings

[email protected]
The contribution of the piston assembly to overall engine frictional losses is well documented and has been the subject of a lot of research over a number of decades. In SAE paper 911230, for example, the authors Tsuchida and Tsuzuku study the effects of various design features on piston friction losses for high-speed engines (up to 16,000 rpm). At the time - the late 1980s and early '90s - the Japanese were selling production motorcycles with engine speeds higher than even Formula One...

DLC for pistons

[email protected]
Pistons are part of the fundamental mechanism of most internal combustion engines, and are certainly very widely employed in racing. While roadcar producers still persist in development of the rotary engine concept, it has been pretty much abandoned by racers, especially by those who produce bespoke race engines. Although rotaries might yet enjoy something of an unexpected revival as range-extenders in electrically driven vehicles, reciprocating (piston) engines will continue to dominate,...
