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 More>

Engine Dyno Testing
 The AEI facility, which includes ten engine dynamometer test cells, is uniquely designed to provide a research and development environment in support of a breadth of diesel engine and/or vehicle development programs.  Read More>

PM Sample Conditioning System

AEI’s system is manufactured for use inside or outside of a test cell. The system is built with a uniquely designed proprietary probe and a temperature controller for maintaining the desired 47C temperature from the sample point to its exit from the system.  Read More>

 

R&D Engineering and Cooperative Development Projects

A key aspect of AEI's business is providing R&D resources to cooperatively develop new products or conduct research for other customers.  Secrecy is important to many customers and the AEI facility has been designed to maintain highly confidential projects in-house.  Examples of past projects are listed below:

 

Turnkey Engine System

AEI specializes in the design and construction of turnkey engine systems for specific applications.  Integrating prototype fuel systems with VG turbochargers, EGR, and exhaust aftertreatment can be a complex task.  AEI has worked with a variety of customers to build these custom engines.   Illustrated in these pictures are projects where the customer required a  "plug and play" engine system that could be used to demonstrate future world class emissions capability.  AEI worked with the customers to design the system, procure or make the hardware, and build the entire test stand system for both functionality and show quality for demonstration purposes.

 

PM Aftertreatment Research System

The capability to measure gaseous species at various locations in the exhaust treatment system allow AEI scientists to more fully understand the chemical and physical property performance of a given aftertreatment system.  Shown is a system that was built for a client to support PM trap development. This capability has helped many customers optimize catalyst compositions.

 

 

Custom Catalyst Test Bench

A catalyst research bench was designed and constructed for a client for three and four way catalysis research.  Capable of 800°C operation, this computer-controlled system is capable of delivering exact mass flow mixtures of up to 7 gases.  A humidity control system in conjunction with digital mass flow controllers allows for cocktail gas mixtures to be exactly controlled in order to study candidate catalysts.
