The C13D currently is going into machine applications for validation in the
dirt, according to Chen, who said he's been working on this development
program for six years. Three customers in the U.S. have been selected for
the durability testing phase. " They were specifically targeted and partnered
with because they will put this engine through the paces, " he said.
The engine will be available for early OEM pilots in 2025 and is
scheduled for production in 2026. According to Cat, the new engine
is intended for applications such as rock crushers, trenchers,
agriculture machines, material-handling equipment
and large industrial pumps.
" We get questions about 'why might you be building a
diesel engine today?' " Stratton said. " First and foremost,
we are one-hundred percent committed to the diesel
platform for the future because we know our customers
are going to need it. If you need a diesel engine, if that's
the right answer, we want the best one on the market. "

Deere pursues electric construction machines and charging infrastructure
the " most heavily used machine form on the jobsite, " Deere said the
145 X-Tier is powered by batteries from Kreisel Electric, in which
Deere acquired a majority stake in early 2022.
Deere says the strategic relationship with Austria-based Kreisel will
Kreisel's patented immersion cooling enables a " uniquely low "
temperature spread of <1° throughout the battery module,
reportedly resulting in a 20% longer lifetime.
John Deere revealed its first electric excavator, the 145
X-Tier, at CES 2023 in January and used the CONEXPO
Show in March to continue showcasing its electrification
strategy. Targeting excavators because they are

serve as " the cornerstone " for electrifying its portfolio of machines.
Kreisel specializes in immersion-cooled battery modules that enable
a " uniquely low " temperature spread of <1° throughout the module,
resulting in a longer lifetime of up to 20%, the company claims.
Kreisel also developed a high-power charging technology called
CHIMERO that is " battery-buffered " - i.e., the integrated battery supplements
the available grid connection to mitigate load peaks, and its
own battery is recharged while charging a vehicle. The commercial
platform with CCS Combo-2 connectors is said to enable up to 180-kW
charging power with a " typically available " 60-kW grid connection and
reportedly costs about 50% less than typical EV fast chargers.
At CONEXPO 2023, John Deere unveiled new Kreisel batteries and
electronic hardware solutions, including a new Gb Ethernet Switch
that manages the transfer of controls information and high-quality
images to multiple devices in a system in real time. In addition to the
63-kWh KBP63 lithium-ion 21700-type battery that was displayed at
Bauma 2022, 20-kWh and 40-kWh power options were on display in
