bets big on
SMALLER ENGINE
The new 2600 Series 13-liter
engine for off-highway machines
will do more with less thanks to
variable geometry turbocharging.

P
erkins announced in September its all-new engine series for
off-highway applications, launching the 2600 Series 13-liter
engine at a press event in London where Truck & Off-Highway
Engineering was in attendance. Perkins states that the 2600
Series is intended for a wide array of off-highway applications including
agricultural tractors, materials handling, construction, mining,
aircraft ground support and other use cases.
" As the off-highway industry advances toward a lower-carbon future,
equipment manufacturers still face expectations for long-term
productivity and reliability in the world's most-demanding work environments, "
said Jaz Gill, vice president of global sales, marketing,
service and parts. " The new Perkins 2600 Series engine platform
demonstrates how we're leveraging our experience, intelligence and
commitment to help OEMs navigate the energy transition with power
solutions that deliver exceptional performance on the worksite. "
During the launch event, Perkins discussed several key details of
the 2600 Series, including complete specs for all versions as well as
overall design goals. Company representatives also confirmed that
the 2600 Series will replace not only the current 13-liter offering, but
also the larger 15- and 18-liter engines in their range.
Just the facts
The 2600 Series is an inline-six single overhead cam (SOHC) architecture
displacing 12.9 liters (787.2 cubic inches) with a bore and
stroke of 130 x 162 mm (5.1 x 6.4 inches). Max output is rated at 690
hp (515 kW) and peak torque is a stout 2,360 lb-ft (3,200 Nm) at

POWERTRAIN FEATURE
The 2600 Series inline-six, which will have eight power ratings ranging from 456
to 690 hp (340 to 515 kW), will be available for early OEM pilots starting in 2025.
1,300 rpm. There will be a total of eight power ratings
ranging from 456 hp (340 kW) to 690 hp depending
on the tier of emissions regulation for the customer's
market. These power levels are all available across a
common core engine.
Currently there are two variants of the 2600 Series:
the 2606J-E13TA and the 2606EA-E13TA. The 2606J is
the EU Stage V / U.S. EPA Tier 4 Final / Japan 2014 /
Korea Stage V compliant version. The 2606EA variant
is specifically rated for China Nonroad Stage IV emissions.
All 2600 Series variants utilize a common rail
direct-injection fuel system and a variable vane geometry
turbocharger.
Perkins states that the integration of several key
components as well as a reduction in the number of
leak joints by 45% has resulted in decreased fluid consumption
and extended oil and fuel filter service intervals
of up to 1,000 hours. Service and maintenance
also has been simplified thanks to design features such
as hydraulic lash adjusters (HLA), service-free open
crankcase ventilation (OCV) filtration, the removal of
all loose washers and a 5,000 hour-rated diesel particulate
filter (DPF).
NVH also has been reduced compared to the outgoing
design, thanks to a combination of a new rear gear
train, stiffer core architecture and the design of the
common rail fuel system. Perkins states a total noise
