180 HP Twin Cylinder Ducati

[Ferrantelli]

The Desmosedici! Desmo is the term engineers gave the system they employ to close and open the valves. Most motorcycles use spring to close the valves and rockers to open them, at revs higher than 8000 the spring begins to loose its effectiveness so Ducati use rockers not only to open the valve but also to close them

Sedici = 16, is the number of valves on their new V-4 motors that develops 200HP.

By the way Tom Cruise just received delivery of the 1ST one in the USA.

i think ducati had desmodromic valves back in the 50's or maybe even earlier. some of the new moto gp bikes are using gas pressure instead of springs to close the valves.it eliminates the coil harmonics that cause valve bounce on the seats,and potential metal fatigue and spring failer at ultra high rpm's.as high tech as these engines are it amazes me they can't come up with a better more efficient mouse trap than the old recprocating internal combustion design.i forgot that the ducati is a v-4. quite a departure from their past. this is a very interesting discussion.as conservative as i am in everyday life. i am really into new engineering technics and innovations. i just designed a new machine for our company that will save hundreds of thousands of dollars. it actually works better than i thought it would.lol really enjoy this type of stuff.

Only the Desmosedici is a V4 Motor. They took the MotoGP Engine and made it street legal and rideable and very exclusive.

 

All other Ducati's are V2 Engines. The 1098 Motor is called 'Testastretta'.

 

For what i know, they use high pressured Air to make the Valves move. Something like small double side action pneumatic Cylinders. This comes from the Formula1 Engines. They have that since Years, because these, former V10, nowerdays V8 Engines work now near 20,000 RpM. There's no Way for Valve Springs in this Dimension of Revelations.

 

 

There is another Designs on the Market. Take a Look a Rotary Engines. Way smaller Displacement and a Lot more Power, compared to Piston Motors. Combined with a Turbocharger, unbelieveable Power with small and light Engines.

for some reason the rotary engines never caught on big. it could be they are not very fuel efficient ,and use total loss lubrication. on the rotor vanes.

The first Rotary Engines have had a Lot of Problems with the internal Seals between the Chambers. This is solved through new and better Materials over the Years. Mazda bought the Patents 30 Years ago and brought up several RX Models through the Years with powerful and reliable Motors.

 

Imho, if only 20 Percent of worldwide spend R&D Money in Motors would have been spend for rotary, they would be far ahead over the Piston now. With all the Efforts on finding reliable Power, Torque and far less Pollution, if the Industry would like to push this Technique, it would be easy. But there are a Lot different Interests involved .... Less Parts would made the Industry suffer and so on.
