From Wikipedia, the free encyclopedia. Where it differs from variable valve timing, which is common in most cars, is that it works ducayi their desmodromic valve system where the valves are lifted mechanically rather than on springs. Despite this increased power and torque this new DVT engine sees an average of eight percent reduction in fuel consumption. Only the front one is used to mate the engine to the trellis frame, with a testastretha bolt.

This ghost view of the Ducati confirms that the toothed belt originally adopted by Taglioni for the Pantah has been retained, despite the good progress that has been made with chains and oil-bath toothed belts such as that used by Ford for its Ecoboost 1. The new crankshaft foreground of the Ducati comes from a new forging with more accurate counterweight profiles and the new, larger main-end journals.

There were also some chassis and aerodynamic modifications. This overlap occurs between the end of the exhaust stroke and the start of the intake stroke and is normally a single value that does not change.

Did you know that we have an online shop full of great stuff! At 94mm by Luxembourg nl Luxembourg fr. Contemporary and iconic, with an essential design, since decades the Monster family combines these elements to sportiness, fun and riding pleasure.

October 20, By Justin Dawes. Though it may sound awkwardly testsatretta, there was a good reason: The plain bearings bring significant enigne in load capacity, mechanical quietness and additional crankshaft rigidity.

Retrieved August 22, Ducati Monster engine close-up. In aerodynamic improvements as well as engine upgrades were standard. Fromthere were three different models: This was also the dycati of liquid cooling and computerised fuel injection to the V-twin range.

The DVT system varies the oil pressure in chambers inside of an external housing affixed to cam belt pulleys to adjust the camshaft timing via an internal mechanism attached to the camshafts. 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 udcati advanced Desmodromic twin-cylinder engine on the planet.

The overlap angle is defined as the interval of crankshaft rotation, expressed in degrees, during which both the intake and exhaust valves are open at the same time. Multistrada means all the Ducati technology, performance and comfort, to live great adventures and travels at any distance on any road. 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 rear one see detail is connected to the rear subframe, supporting the seat and using an 18mm bolt. This optimizes combustion without increasing emissions, by completing the oxidisation of ducatu hydrocarbonsto reduce HC and CO levels. The fuel injectors have been repositioned to target their spray directly on the hot intake valve rather than the intake port wall. Thanks to this unique system, the intake and exhaust valves are closed mechanically and with the same level of accuracy as they tesstastretta opened.

Still, he did not want to use too much oil flow and pressure, so he decided for a hybrid solution for the Pantah: The Dcuati Desmoquattro are water-cooledfour-valve engines from Ducati. The resulting enhanced fuel vapourisation improves combustion efficiency and ensures a smoother delivery. Ducati presents the first motorcycle engine with variable timing of both the intake and exhaust camshafts.

The highest peak of technology and Ducati design to reach the maximum perfomances. The DVT system consists of an external housing, rigidly connected to the cam belt pulley, and an internal mechanism which is connected to the camshaft and can independently rotate inside the housing.

Each spark plug is managed independently, to optimise efficiency throughout the rev range and in all conditions of use. With full Euro 4 compliance, DVT sets a new standard in the combination of power, delivery and usability of motorcycle engines. The new retains the basic character and layout of the original members of the testaxtretta, but looks neater, refined and more rational in the design of ancillaries such as the belt covers, which feature a net-protected air intake to keep the operating temps of the belt under control.

Ducati Monster engine. The smaller bore produces a stronger case structure thanks to the thicker annular section around the main bearing seat, plus additional webbing.

In order to achieve a smoother cycle-to-cycle engine operation, Ducati has used a secondary air system similar to that developed for extremely high-performance engines. A “symphony” of performance. Enter and find out.

Enngine Ducati features a The new Testastretta head’s included valve angle was reduced from 40 degrees to 25 degrees which was more in line with current F1 four-valve theory.

Skip to main content. This is the new oil pump. The vertical head of the Monster with its two additional bosses. The full Ducati press release is reprinted below for your edification. The larger main journals generate a much more rigid crankshaft because now they overlap the crank journal by a substantial 8. The bottom end is derived from the DS Desmodue, with the water pump in the alternator cover. The Ducati Testastretta DVT is the first motorcycle engine with variable valve timing of both the intake and exhaust camshafts.
