When did Ducati start using desmodromic valve actuation?
Desmodromic valve actuation has been applied to top-of-the-range production Ducati motorcycles since 1968, with the introduction of the "widecase" Mark 3 single cylinders. In 1959, the Maserati brothers introduced one of their final designs: a desmodromic four-cylinder, 2000cc engine for their last O.S.C.A.
How are the valves opened in a desmodromic engine?
In a conventional four-stroke engine valves are opened by a cam and closed by return spring. An engine using desmodromic valves has two cams and two actuators, each for positive opening and closing without a return spring.
What does desmodromic mean in mechanical terms?
In general mechanical terms, the word desmodromic is used to refer to mechanisms that have different controls for their actuation in different directions. Desmodromic poppet valve in Ducati engine.
Why do Ducatis use Desmo instead of springs?
Thus desmo eliminates the usual problems with springs (read on), while the absence of conventional spring load saves some frictional loss at low to mid-rpm. Ultimately, Ducati uses desmo because it knows desmo and also because it is known for desmo.
