In the Ducati appeared, and only lasted for one season. From the GTV, Taglioni drew on basic experience that would change his very conservative approach to crank assembly design—the plain bearings and related forged one-piece crankshaft and cap-type rods were the optimal solution to solve the dramatic problem of multiple failures of the traditional pressed together crankshafts turning on ball and needle bearings.

Though it may sound awkwardly complex, there was a good reason: Thanks to all these characteristics, the Ducati Testastretta DVT sets new standards for Ducati twin cylinder power units and introduces new, revolutionary parameters to achieve the best possible balance among maximum power, smooth delivery, low-rpm torque, low fuel consumption and reduced emissions, thus standing out as the most technologically advanced Desmodromic twin-cylinder engine on the planet.

Ducati Monster engine. The pocket deep and spoon-shaped exploits the high-pressure injection jet of gasoline to enhance the turbulence inside the combustion chamber, for faster and more complete combustion. The Ducati R Xerox race replica was introduced in To enable the Testastretta engines to function as stressed members of the chassis which also has a steel trellis frameadditional engine-to-frame mounting bosses had to be added to the horizontal head one on the top side and the vertical head one at the front, one at testastrstta rear.

This rotation of the internal mechanism, either in advance or in delay with respect to the housing, is precisely controlled by varying the oil pressure in special chambers of the mechanism. With its mm bore and This causes greater vaporization for a more efficient fuel burn.

A reed valve atop of it controls flow. October 20, By Justin Dawes. The main-end plain bearings do not feature the usual groove and admission hole because Taglioni has always favored axial admission lubrication circuits, which require less pressure.

Fabio Taglioni designed back in the mids. The Testastretta DVT produces a testasrtetta horsepower at rpm and lb-ft of maximum torque at rpm. With full Euro 4 compliance, DVT sets a new standard in the combination of power, delivery and usability of motorcycle engines.

Multistrada S D Air.

Sleek tailpiece lines of the Monster R grab the eyes with their sporting looks. They had superb radial loads and axial thrust capacity, and thanks to their lightweight synthetic material cages they could stand extremely high rpm. Your email address will not be published. The Ducati Testastretta DVT system does not affect the valve clearance adjustment schedule, and in fact requires major services only at ownership-friendly 30, km intervals.

The new crankshaft foreground of the Ducati comes from a new forging with more accurate counterweight profiles and the new, larger main-end journals. Canada en Canada fr. Quietly, the is bringing radical change to the family of degree V-twins derived from the original 8-Valve Desmo, which, in turn, was based on the Pantah that Dr.

A new engine joins forces with the Ducati Dudati Shift gearbox to achieve acceleration and adrenaline. The full Ducati press release is reprinted below for your edification. Ducati Monster engine close-up.

The oil pressure is adjusted by dedicated valves teztastretta the timing of each cam is dynamically controlled by a sensor located in the cam covers. For the technically minded it means variable timing on both the intake and exhaust camshafts with engind overlap angle.

An anti-knock sensor ensures safe engine operation even while using lower octane fuel or in situations potentially detrimental to combustion efficiency, e. The torque is already 80Nm at a low-range value of rpm, tstastretta it remains consistently over Nm between and rpm.

View the discussion thread. Enter the Land of Joy. Ducati Monster studio. The Testastretta DVT is equipped with a Dual Spark DS system that uses two spark plugs per cylinder head, providing a twin flame-front that ensures complete combustion across a very short period of time. Skip to main content. Languages Italiano Edit links. The resulting enhanced fuel vapourisation improves combustion efficiency and ensures a smoother delivery.

Hypermotard means maximum fun everywhere. The bore goes down from the old 81mm to 45mm. In the development of the DVT, the Desmodromic valvetrain represents a major advantage over a traditional spring based timing system; the actuation of the valves at low engine speed requires less force, not having to compress the valve springs, this allowed Ducati to limit testastretga size of each cam phaser with obvious benefits tsetastretta terms of lightweight construction and compactness for a perfect engine integration.
