CLEANSLATE INNOVATION DELIVERS ENGINE POWER,
FLEXIBILITY AND RELIABILITY
A new engine has been designed to deliver
optimal reliability, exibility and
serviceability, representing a customizable
solution for OEM customers to meet a wide
range of heavy-duty applications and power
needs in construction, agriculture and beyond.
e new PowerTech 13.6L industrial engine
from John Deere Power Systems improves total
engine life cycle, o ers a smaller size
and weight for easy machine integration, and
incorporates a rear gear train for reduced noise
and enhanced operational exibility.
What makes it different?
Much of the development for diesel engines in
the past decade has been in uenced
by upcoming emissions
regulations. Now that the
industry is largely beyond
new emissions tiers,
John Deere sought to
leverage the
technologies it had
developed to optimize
its product.
e product’s cleansheet
design – a process
undertaken from the
ground up – sets it apart from
other o erings, leveraging
technologies in new ways to meet market
and customer demands. e engine was designed
with more computer-model-based development
than past John Deere engines, which resulted in
more virtual simulation versus test cell time.
“You can simulate so much more today,” says
Sandrine Couasnon, marketing manager for John
Deere Power Systems. “In the past we had to
utilize a test cell and empirical data to de ne
further development, where today those
iterations can occur faster with simulation. John

Deere dedicated extensive internal resources to
the clean-sheet design of this engine to provide
our customers with a power solution that
surpasses standards in reliability and durability.”
New technologies
e 13.6L engine was designed with a focus on
delivering increased e ciency, installation
exibility, and power in a more compact package.
Using a 6-cylinder in-line design, the engine will
have outputs over 670hp (500kW) variable speed,
all in a small, light, and uid-e cient package.
e block-mounted exhaust gas recirculation
(ERG) cooler is incorporated into the
fundamental design of the engine, which is a
signi cant advantage for integration and
packaging. In addition, the compact
package is simple to maintain
and Stage V-compliant.
Additional technologies
that contribute to enhanced
design and performance
include, integrated wiring
harness and sensors, which
signi cantly enhance
reliability by reducing
vibration. Engine quality and
ease of integration are also
improved because the wiring
harness comes already installed and
the overall number of sensors is reduced.
Additional joints and pipes in the coolant and
oil passes, reduce potential leak paths and improve
reliability. Meanwhile an engine-mounted engine
control unit (ECU) doesn’t require cooling of fuel
or coolant, in comparison to previous engine
models that required a fuel-cooled or air-cooled
ECU based on temperature requirements. is
change also reduces leak points and complexity.
e gear train is located in the rear of the
engine, which reduces the level of noise and
torsional vibration compared to a gear train
located in the front of the engine. is helps to
directly improves the engine durability while also
enhancing its operational exibility, since it
enables more gear drive auxiliary power
take-o capabilities.
An in-line integrated emissions control
system (IECS) that can be mounted horizontally
or vertically, o ering packaging and integration
exibility. e added exibility also reduces
connection points and optimizes thermal
management.
Furthermore, integrated hydraulic lash
adjusters (HLAs) directly improve service costs and
intervals. e adjusters are hydraulically operated
and self-adjusting, eliminating the lengthy service
process of manually resetting the valve lash.
Benefi ts for performance
One point in the design of the new 13.6L
engine was an emphasis on total engine
lifecycle, which was improved by optimizing
construction, thermal management systems, uid
e ciency and more.
Because the 13.6L is about 18% smaller and
10% lighter than its predecessor, power and
packaging needs for a range of heavy-duty
applications can be met. In addition, the engine
was engineered speci cally with service and
repair in mind.
e clean-sheet design approach for the 13.6L
allowed John Deere to put customer and market
needs front and center – leveraging technologies
to deliver an engine optimized for reliability,
exibility, and serviceability. iVT
