Exhaust Aftertreatment
Much of AEI’s business
revolves around proprietary exhaust aftertreatment system
development. AEI’s personnel, testing facilities, and emissions
analyzers are ideally suited for the development of new aftertreatment
technology. Read

Mass Flow
Measurement
.jpg) AEI has
developed
and
patented a method for measuring
diesel
exhaust mass flow
rate. (US Pat# 6,668,663) These systems are
manufactured to provide
flow rate measurements on exhaust pipe sizes ranging from 2-8”
in diameter.
The flow
measurement system was developed by AEI in response to a need for
a durable, easy-to-install flow measurement device on diesel
exhaust. Initially, AEI tested several other commercially
available flow meters, but experienced issues with fouling of the
flow sensor that would quickly create erroneous flow rates. In
order to obtain reliable exhaust flow measurements, AEI developed
a device that would provide consistent data when installed on a
vehicle for at least a week’s operation. This device was used for
collecting
emissions and duty cycle information on over 50 different off-road
vehicles,
collectively establishing more than 6000 hours worth of data.
This device has also been used for on-highway diesel trucks,
ranging from class 8 semis to pickup trucks.
