“With Tier 4 final emissions requirements just around the corner, controlling exhaust gas temperature
(EGT) will be a critical function for
all off-road equipment manufacturers,” said Stefan Jennewein, vice
president, sales and marketing at
Active Exhaust. “Our customers typically provide us with the vehicle envelope including the engine and emissions level output, desired engine
and device interface option, as well
as any other product-specific requirements such as targeted skin surface
temperature, vibration and durability
requirements, product finish and engineering cost targets.
“Our design, engineering and
manufacturing team evaluates these
application-specific requirements
and we typically submit a tech-
nology and cost proposal within a
10-day timeframe. Upon acceptance
by the customer, we proceed with
prototype testing, final assembly
drawings and manufacturing readi-
ness, which depending on the com-
plexity, takes approximately two to
three weeks.”
As different manufacturers and dif-
ferent markets often have their own
preferences to emissions reduction
technologies — relying on exhaust
gas recirculation (EGR), selective cat-
alytic reduction (SCR), diesel oxida-
tion catalysts (DOCs), diesel particu-
late filters (DPFs) or a combination of
technologies — Active is experienced
in packaging and integrating a wide
range of emissions options. Each
application requires a structured engi-
neering approach and careful mate-
rial selection in order to meet durabil-
ity requirements and cost targets, the
company said.
“Some advantages we have are our
close working relationship with global
technology providers and engine and
equipment manufacturers, as well as
our vertically integrated engineering,
testing and manufacturing facility in
Toronto, which allows us to take a
product from the initial design concept
