Automotive wants to welcome the English Audience with a beautiful Engineering concept. The Desmodromic System.
The Desmodromic System is a concept developed to avoid the catastrophic effect that appears at high rpms of the Otto Cycled Internal Combustion Engines. The Desmodromic System avoids the known floating valve effect which appears when the spring of the valve cannot recover from the camshaft push being the valve pushed again before it has closed the combustion chamber.
The subsequent and critical problems of this are two:
The piston hits the valve as it remains open and this could break the rod and also the performance of the engine is almost null as the compression in the cylinder will very low and it is not possible to complete the four stages of the combustion.
A mechanical solution to this is the Desmodromic System with Fabio Taglioni as the most representative engineer for the System since 1956 which is still being used by Ducati in their current motorcycles.
This System mainly consists on having two rods one for opening and one for closing the valve. This makes technically impossible the floating valve effect at high speed revs.
Computer Sciences have demonstrated that nowadays is not best solution in terms of performance and neither the knowledge of this System which demands a lot from the designer allows a big use of this mechanically beutiful System.
(Still needs more references and supervision, so all of this has to be considered as a draft version)
