old: Honda's Superior Supercharger

TNT writes "Supercharging has always had its shortcomings, mainly high cost, complexity and packaging requirements. According to PRIMedia, “these drawbacks… may be a thing of the past, if Honda follows through on an potential breakthrough system…” Their story continues:
The Honda concept employs the underside of the pistons in a 4-stroke engine to act as compressors in much the same way some 2-stroke engines are crankcase-scavenged.
When applied to the 4-stroke engine, each "piston compressor" pumps two volumes of air for each intake cycle, permitting pressurization of the intake charge.
Among the innovative features Honda proposes for its self-supercharged 4-stroke engine designs are:
* A large intake manifold chamber, called a "pressure air reservoir," dampens pressure pulses before passing air through the intake valves and into the combustion chamber.
* Two proposals for eliminating crankcase lubricating oil from the induction air. In one, the intake port could be designed so that induction air is forced into a spiral motion with a centrifugal separation action. The oil would be recycled for lubrication of the lower end of the engine. A second approach employs a similar centrifugal separating action in the pressure air reservoir, in this case designed with a cylindrical shape and a slightly smaller, perforated inner wall.
* A variable-displacement pressure air reservoir that reduces filling efficiency when an engine brake is applied.
* A dry sump arrangement to save packaging space.
This new approach would increase output without increasing size, and it would be factory warranted. Now the question is, will one of these new motors be able to be swapped into a del Sol?
