LAS VEGAS
Big reveals abounded at the
triennial CONEXPO trade show.
Following are some of the most notable
unveilings from the desert.
Cat doubles down on diesel with new C13D platform
Caterpillar launched its new off-highway 13-liter diesel engine platform,
the C13D, in dramatic fashion on the field inside Allegiant
Stadium in Las Vegas. Cat states that the C13D was " purpose-built for
rugged, long-lasting performance in off-highway applications " and
that the new engine was designed to realize increased power density,
torque and fuel efficiency.
" Off-highway OEMs and equipment owners face a rapidly evolving
business environment that demands improved worksite productivity
and reduced operating costs while addressing increasingly stringent
emissions standards, " said Steve Ferguson, senior vice president
Caterpillar Industrial Power Systems. " Internal-combustion engines
are the prevailing workhorses on most jobsites around the world,
which is why we've invested in the next-generation Cat C13D diesel
engine platform to address their challenges. "
New and improved
The C13D is an inline, six-cylinder turbocharged design that will be
offered in eight power ratings ranging from 456 to 690 hp (340 to
515 kW) with a peak torque rating of 3,200 Nm (2,360 lb-ft). Cat said
that all power ratings will be available with no alterations to the
C13D's core architecture. The C13D also will meet emissions standards
for all markets, such as EU Stage V, U.S. EPA Tier 4 Final, China Nonroad
IV, Korea Stage V and Japan 2014. C13D models also will be
available for less regulated markets, according to Cat.
The company's philosophy for developing the C13D platform was
to supply comparable power and torque to what its current 13-, 15and
single-turbo 18-liter engine platforms offer. By providing a range
of power outputs within a single engine platform, Cat believes that it
can consolidate design, assembly and supply-chain requirements
across multiple applications.

The C13D will
be available for
early OEM pilots
in 2025 and is
scheduled for
production in 2026.
" It's a similar footprint to our current 13-liter and it's
obviously smaller than our 15- and 18-liter [engines], "
said Mark Stratton, VP and general manager of
Caterpillar's large industrial engines business. " It
comes in at just 2,500 lbs. (1,134 kg). So, we've taken
weight out of it but added strength and durability. "
Stratton said the C13D offers up to a 20% increase in
total power and as much as 25% more low-speed
torque compared to the previous-generation engine.
