TECHNICAL INNOVATIONS
PROPULSION
Hyliion, Cummins collaborate on electric and NG range-extender
A recent market report found that nearly
85% of the almost 250 U.S.-based transportation
fleets surveyed plan to grow
their use of clean-vehicle technologies
over the next five years. Fleets will have
one more option come late 2023.
Hyliion, an Austin, Texas-based provider
of electrified powertrains for Class
8 semi-trucks, and Cummins announced
a collaboration to optimize Cummins'
ISX12N natural-gas (NG) engine as the
onboard generator for Hyliion's
Hypertruck ERX powertrain. The
Hypertruck ERX provides 75 miles (120
km) of electric range and qualifies for
credits under CARB's upcoming ZEV
mandates. The truck reportedly can
achieve up to 1,000 miles (1,610 km) of
full range through the NG-fueled generator
recharging the batteries.
" We are excited to work with Hyliion to
offer this range-extender electric and
Low-cost refueling is a major
benefit of the powertrain solution,
the companies claim.
natural-gas powertrain in the North
America heavy-duty truck market, " J.
Michael Taylor, general manager Global
Powertrain Integration, Cummins Inc.,
said in a statement. " Natural-gas solutions
are an integral part of our journey
towards zero emissions. Integrating our
REDUCED EMISSIONS
From inventing compression release technology to developing
next-generation valve trains and advanced braking systems, we
are continually raising the levels of performance - for power, fuel
economy, and reduced emissions - that heavy-duty commercial
vehicles can achieve.
Jacobs' Cylinder Deactivation (CDA) system aids in meeting stringent
fuel economy standards such as the new ultra-low NOx standards
and drive cycle. Independent testing has shown up to a 25% fuel
savings, a 77% decrease in NOx, and a 12% reduction in CO2
.
engine with the Hyliion Hypertruck ERX
solution is key to offering our customers a
portfolio of powertrains across many fuel
options to meet their sustainability goals. "
The companies plan to obtain key
environmental certifications for
Cummins' natural-gas ICEs to be used
DOUBLE ENGINE
BRAKING POWER
Jacobs High Power Density engine brake offers a 100% increase in engine
braking power at low cruise RPM (1200 - 1400) and has established itself as
an impressive alternative to existing braking technologies. It is a milestone in
the evolution of Jacobs' famous engine brake solutions.
