Whatever happened to sleeve valve engines?
The Hawker Tempest was the fastest piston powered airplane ever made, it had a sleeve valve engine. It was made obsolete, by the Me 262 and other jet engined fighters, But it's engine was the ultimate piston aircraft engine. Then piston engines became something for inexpensive planes, but why has the sleeve valve not undergone further development as a sports car engine?
The main problem was the oil consumption, since a very tight seal required close tolerances that in turn called for very precise lubrication.
As Wikipedia states (see link) if one wants to do away with poppet valves, and is willing to accept a very wide lubricated area, one might as well go all the way and go with a Wankel rotary engine which entirely eliminates the need for valve and thus timing gearing.
Note that military engines do not have to be certified the way civilian aero engine need be, this in turn makes the process of introducing any change in an engine design extraordinarily expensive, hence general aviation piston engines are rather crude (but proven) design.
For automotive engines, one of the concern is the economy of scale: it is pointless to make an engine, to invest in all the development cost, if only a handful are produced. And it is pointless to make an engine that is meant for a wide distribution unless the cost of the final product is attractive, and that the maintenance expertise is properly widespread. So again, innovation tends to be introduced very slowly.
And you cannot count on auto racing to act as a test bench for such innovations, as the rules there are often actually meant to limit how innovative one can be...
