How does a desmodromic valve work?
How does a desmodromic valve work?
Desmodromic engines close valves with another cam. They use use two cams and two actuators, avoiding using a return spring. So one cam pushes the valve open, and another valve pushes it closed.
How does Ducati Desmosedici work?
Desmo is short for desmodromic, and it refers to the way that a poppet valve inside of an engine is controlled. In almost every four-stroke piston engine, the valves are opened via a camshaft and closed by spring pressure which comes from a valve spring. It’s a well-known system, it works, and it’s pretty simple.
Does Ducati still use desmo?
Desmodromic engines are still being used by Ducati, notably in the MotoGP competition machine, the Desmosedici GP19 as well as the current crop of Panigale V4 super bikes along with the Diavel power cruiser and Multistrada 1260 adventure tourers in V-twin form.
What engine valve design is Ducati famous for?
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.
Is Ducati a v4 desmo?
We’re seeing the storied Italian brand venture further and further out from its traditional comfort zone and that’s very exciting.
Are all Ducatis dry clutches?
Dry clutches used to be fairly common—Ducati famously used them for decades—but today the vast majority of motorcycles being made employ wet clutches.
Is the Ducati v4r automatic?
The Ducati Panigale V4 is a sport bike with a 1,103 cc (67.3 cu in) desmodromic 90° V4 engine introduced by Ducati in 2018 as the successor to the V-twin engined 1299….Ducati Panigale V4.

How long will a Ducati engine last?
Despite this, Ducati Monsters can last long with proper maintenance and care. From the owners’ reports, you can get 40,000 to 80,000 miles on a Monster before it breaks down. Some owners have even reported crossing the 100,000-mile mark on their Monster bikes.
Why did Ducati choose desmodromic valve drive?
After World War II, when future Ducati engineer Fabio Taglioni wrote his original engineering-school paper on desmodromic valve drive, there was good reason to seek such a system: Valve springs broke at random as an era of rising rpm opened. In the 1950s, NSU pushed to 12,000 rpm, and by 1957, Mondial’s 125 was revving to 13,000.
Why did Ducati continue with Desmo in MotoGP?
In 2003, when I asked Claudio Domenicali, then in charge of racing and now CEO, why Ducati continued with desmo in MotoGP, he said, “Because it is the system we know best.” The company had, naturally, looked into pneumatic springs but understood: 1) it would cost a lot of money, and 2) there would then be a totally unfamiliar learning curve.
What is the history of Ducati?
Thanks to Fabio Taglioni, the original creator and genius behind the Desmo valve system, Ducati is now a name known all around the world for the unbeatable performance of their motorcycles. Read more on Fabio Taglioni here or explore the full history of Ducati here , on the official Ducati website.
How does a Ducati engine work?
Ducati engines are short stroke high revving engines (as far as twins go that is). The more conventional valve control systems used in Japanese motorcycles use a valve spring to return the valve to its closed position when the lobe on the camshaft releases its downward force.
