LAKE FOREST, Ill., March 25, 2021 /PRNewswire/ -- Power
management company Eaton (NYSE:
ETN) and Tenneco (NYSE: TEN) today announced a joint development
agreement between Eaton's Vehicle
Group and Tenneco's Clean Air business group to produce an
integrated exhaust thermal management system that will enable
commercial truck and light vehicle manufacturers to meet upcoming
emissions regulations.
Across the globe, emission standards are tightening for vehicle
manufacturers. In Europe, the next stage of emissions
standards, known as Euro 7 (for
light-duty vehicles) and Euro VII (for heavy-duty), are targeted
for introduction in 2025. The California Air Resources Board (CARB)
and the U.S. Environmental Protection Agency (EPA) have similar
actions planned for 2024 and 2027, respectively. Collectively,
these new regulations will reduce tailpipe NOx limits by 90
percent, thus accelerating the need for global engine manufactures
to employ additional emission reduction strategies.
Under terms of the agreement, Tenneco's Cold Start Thermal Unit
(CSTU) will be combined with Eaton's TVS® blower technology. The
integrated exhaust thermal management system will provide heat
directly to the vehicle's aftertreatment system, which is essential
for reducing harmful exhaust emissions. Upon heating the SCR
catalyst to approximately 200 – 250 degrees Celsius, the
aftertreatment system can efficiently convert NOx into clean
emissions (e.g., nitrogen and water particles) upon exiting the SCR
catalyst. Eaton's electrically
driven TVS Roots blower allows the airflow to be efficiently and
precisely controlled so the CSTU can maintain optimal
aftertreatment temperatures.
"CSTU is an active thermal management technology that rapidly
heats and maintains the emission control system temperature," said
Nick Morley, director, global
advanced engineering, Tenneco's Clean Air business group. "Since
the majority of emissions are generated during the initial start of
engine operation and during extended idle conditions, the addition
of an integrated exhaust thermal management system in front of the
catalyst enables rapid light-off and efficient NOx conversion
through the full range of operating conditions."
"It became clear about three years ago that future CARB and EPA
NOx regulations would be drastically stricter than they are today,
and the exhaust thermal management system is an effective
technology to actively heat up an aftertreatment system for
commercial vehicle diesel engines to dramatically reduce cold-start
NOx emissions," said Justin Hopkins,
technology development manager, Eaton's Vehicle Group.
"Tenneco is an established leader in the design and development
of aftertreatment solutions," said Dmitri
Konson, vice president global engineering for Tenneco's
Clean Air business. "We are pleased to partner with Eaton to develop a fully optimized system for
engine manufacturers, leveraging our aftertreatment technology and
engineering capabilities."
The integrated exhaust thermal management system is already
drawing attention from several global manufacturers, who are
currently selecting which powertrain technology will help them meet
future emissions regulations. By adopting this solution complicated
multi-injector, light-off catalyst systems, with close-coupled
packaging can be eliminated thereby reducing complexity. The
CSTU and TVS blower will be sold individually by Tenneco and
Eaton, respectively, but will be
engineered as a system enabling vehicle manufacturers to seamlessly
integrate the components.
Development activities will take place at Tenneco's technical
center in Edenkoben, Germany, and
Eaton's technical center in
Marshall, Michigan. The integrated
exhaust thermal management system is anticipated to be ready for
start of production in 2025 to support regulatory timing.
