Tenneco Showcasing Clean Air, Ride Performance Solutions at 2016 IAA Commercial Vehicle Show
LAKE FOREST, Ill.--(BUSINESS WIRE)--
Tenneco Inc. (NYSE:TEN) is displaying its latest Clean Air and Ride
Performance solutions that reduce emissions, contribute to improved fuel
consumption and improve vehicle performance at the 2016 IAA Commercial
Vehicle Show, Hannover, Germany, September 22-29, 2016.
“Tenneco’s portfolio of Clean Air and Ride Performance technologies are
production-ready and meet the needs of our commercial vehicle customers
anywhere in the world,” said Tim Jackson, chief technology officer,
Tenneco. “From diesel aftertreatment solutions designed to meet
stringent emissions regulations to complete ride control systems and NVH
solutions for a superior operator driving experience, Tenneco delivers
commercial vehicle systems that are cleaner, quieter, and smoother.”
Located in Hall 16, Stand C10, Tenneco will exhibit these and other
advanced technologies:
Clean Air
XNOx™ Urea Selective Catalytic Reduction (SCR). Tenneco’s latest
evolution of its XNOx urea dosing system offers expanded thermal range,
so that the system can be placed closer to the turbocharger without
compromising dosing quality and performance. The return flow design
provides superior thermal tolerance without added complexity. Other
enhancements include an optional controller, which features a flexible
engine interface design and can predict engine-out NOx and account for
ammonia storage and catalyst degradation. Tenneco’s patented injector,
specifically designed for exhaust systems, delivers an optimized
solution, enabling greater than 95 percent NOx conversion efficiency,
helping customers to meet stringent emissions standards while delivering
engine performance.
Advanced Mixing Technologies. Tenneco’s custom-engineered mixing
components ensure consistent mixing of liquid urea and optimized
performance of the selective catalytic reduction (SCR) aftertreatment in
diesel engine exhaust systems. The company is showcasing its latest
family of mixing solutions designed to efficiently process the injected
DEF into gaseous ammonia without the formation of undesired deposits,
even at low engine loads. This strategy supports meeting extreme NOx
efficiency requirements for low or non-EGR calibrations as well as
emission targets under real field operations. A key functional component
is Tenneco’s patented Swirl Pipe Mixer, which can be incorporated into
Tenneco’s Euro VI box solution, integrated into outlet cones or applied
as a stand-alone mixing unit into Tenneco's MixBox.
Euro VI Plus Concept Box. In compliance with current Euro VI
regulations for on-road trucks, Tenneco has developed a compact and
modular one-box solution that includes all required exhaust
aftertreatment components, such as DOC, DPF and SCR converters as well
as the company's proprietary advanced mixing technology. The concept box
also features advanced technologies designed to support further
reductions in NOx emissions and In-Service Conformity (ISC)
requirements, including thermal management solutions such as lightweight
fabricated manifolds and active heaters to support low temperature NOx
efficiency. Another important focus for the commercial vehicle market –
driven by total cost of ownership and CO2 legislation – is
waste heat recovery. Tenneco is developing solutions to provide or
integrate heat exchangers into the Euro VI box as a key component of
Rankine cycle-based systems that convert wasted exhaust heat into
mechanical power.
Ride Performance
CVSAe is part of Tenneco’s Monroe Intelligent Suspension
portfolio and is a semi-active suspension system that helps improve
driving safety, protect freight and reduce tire wear on light commercial
vehicles. The system continuously adjusts shock absorber damping levels
to road conditions and vehicle dynamics like speed, turning, cornering
and driver inputs to deliver optimal ride comfort and vehicle control in
all road and driving situations. The driver can also select between a
more comfortable or more dynamic driving style.
Position-Sensitive Twin System (PST) is a multi-stage hydraulic
shock absorber that provides different levels of damping based on the
position of the pistons within the shock absorber pressure tube. The
PST’s design enables a wide range of tuning parameters. Almost any
desired damping curve can be obtained while avoiding sudden transitions
in performance between soft and hard damping modes. PST allows the
choice of different damping forces for rebound and compression. This
high degree of tuneability is critical for OEMs who desire specific ride
characteristics.
45mm Axle Dampers are used primarily as rear axle dampers for
vehicles with a gross vehicle weight (GVW) greater than 15 tons and on
trailers. A new valve system provides increased tuneability and allows
higher compression damping force while maintaining the lifetime
performance typical of Tenneco dampers. Tenneco also offers 35mm Axle
Dampers, generally used as front dampers for vehicles with a GVW
between six and 15 tons.
Cabin Suspension systems include Coil Spring Cabin Dampers,
Air Spring Cabin Dampers and Lateral Cabin Dampers. Coil Spring
over Shock (CSOS) and Air Spring over Shock (ASOS) cabin
suspensions differ in terms of the natural frequency of the mass-spring
system to provide optimized robustness and comfort. Lateral Dampers provide
high damping at low piston speeds to keep the swing movements of the cab
under control. Integrated Height Valve (IHV) is an internal valve
within the air spring damper module for cabin leveling which reduces
assembly complexity, time and cost. This modular solution can be adapted
to customer-specific needs and doesn’t require any additional external
links or connections.
Adjustable Seat Dampers are optimized for the very low seat
movement and allow the driver to choose the optimum setting adapted to
his weight and driving preferences.
Elastomers
Lightweight Torque Rods deliver high performance and fatigue life
while minimizing vehicle mass. Tenneco’s innovative rod designs help
customers to meet performance targets with simple, low mass solutions.
Multiple construction options are available.
Innovative Spring Eye Bushings are part of Tenneco’s Clevite®
Elastomers brand, which has been manufacturing elastomer suspension
bushings continuously since 1947. Spring eye bushings serve as key
pivots in vehicles with leaf spring suspensions, and new designs that
reduce mass while improving bushing function and fatigue life are
currently in validation. High radial and conical spring rate are paired
with low torsional breakaway to produce pivots ideally suited for
optimal suspension performance.
Tenneco is an $8.2 billion global manufacturing company with
headquarters in Lake Forest, Illinois and approximately 30,000 employees
worldwide.Tenneco is one of the world’s largest designers,
manufacturers and marketers of clean air and ride performance products
and systems for automotive and commercial vehicle original equipment
markets and the aftermarket.Tenneco’s principal brand names are
Monroe®, Walker®, XNOx® and Clevite®Elastomers.
