Ducati Announces Its First Ever Desmodromic Variable Timing Engine
With the EICMA Motorcycle Show around the
corner in Milan, Ducati released
its newest 1198cc Testastretta engine, which is the first ever
motorcycle engine that has variable valve timing with its intake
and exhaust camshafts, Motorcycle USA reported.
Ducati explained the Desmodromic Variable Timing (DVT) gives the
engine the most power, smoothest delivery and "muscular torque at
low rpm," which will limit overall fuel consumption as well, the
source reported.
Variable valve timing is not completely new on the market as the
Kawasaki
Concours 14 has VVT as well. However, the DVT is the first of
its kind that can continually adjust its exhaust cam and the
intake. The system will allow the engine to have fewer hiccups and
run a smoother ride.
Ducati used this technology from its new parent company,
Volkswagen, to create the V-twin engine, Auto Blog reported. The
German automaker is notorious for using everyone involved with the
company for input and design, and Volkswagen didn't let up with its
design of the new Ducati DVT engine.
Additionally, Volkswagen recently had Ducati help design the new
high-performance XL1, which owns a 190-horsepower engine, has a
drastically low curb weight and isn't a gas guzzler like many of
the other extreme sports cars, Auto Blog reported.
"[The DVT can be used in a] wide variety of conditions and
locations, while always delivering top performance and exceptional
user- friendliness, safety and sheer excitement," Ducati stated in
a press release.
Easier Power Delivery
The Testastretta L-Twin variable timing
engine has a peak 160-horsepower limit and 100.3-pound-foot torque,
Ultimate Motorcycling reported. The engine has 10 additional hp and
10 more pound-feet of torque than its current Multistrada 1198cc
engine.
The DVT can achieve a peak power of 9500 rpm, which is also 250 rpm
more than the Multistrada as well. However, even though the DVT is
more powerful than other models, it actually uses less fuel as
well. Ducati explained the engine consumes 8 percent less fuel on
average when compared to non-variable timing engines, the source
reported.
"[The repositioned fuel injectors] target their spray directly onto
the rear of the hot intake valve, instead of the colder surface of
the intake port wall," Ducati said in its press release. "The
resulting enhanced fuel vaporization improves combustion efficiency
and ensures a smoother delivery."
