Client:  EPA - National Vehicle and Fuel Emission Laboratory
Project:  Develop an Automated Emission Control System for the
             Cummis Engine

Emission standards for diesel engines have been
substantially tightened for the model year 2007.
Manufacturers claim the standards cannot be met
in a production engine.  To determine the feasibility
of these new regulations, EPA's National Vehicle
and Fuel Emission Laboratory (EPA_NVFEL) set out
to develop an emission control system to meet the
new standards demands.

EPA_NVFEL awarded ADS, the contract to develop an automated,
computer-based Emission Control System for a large diesel engine.  The
system provides the ability to remotely monitor and control a Bosch
Engine Controller through a National Instrument LabVIEW Real-time (RT)
program and PXI controller.  In addition, ADS used LabVIEW to develop
an engine simulator; redesign and recode the current ECS software
written by EPA to run under LabVIEW RT.

Client:  Siemens Automated Fuel Division
Project:  Build an Automated Data Acquisition Test Stand for Fuel
            Regulators

Siemens Automotive Fuel Division tests fuel
regulators for automotive manufacturers.  ADS
developed a flexible automotive data acquisition system.  This turnkey
system dramatically improved the operation and data collection for their
fuel regulator test stands.

This division had operated and collected data from their fuel regulator
test stands with a Quick Basic (QBasic) application.  Maintaining and
upgrading their test stand application was difficult because little QBasic
product support existed (either internally or externally to Siemens).  
When Siemens reached the maximum capacity of the QBasic application,
they decided they needed a new data acquisition system for their fuel
regulator systems using a software development tool that would be
flexible, expandable and provide them with unprecedented technical
support.  ADS met their needs with a software tool based on National
Instrument's LabVIEW.

This LabVIEW-based system incorporates current testing procedures and
data collection through Graphical User Interfaces (GUIs), uses a remote
trigger switch to send data directly to the computer and automatically
generate custom reports using a Microsoft Office platform.  The system's
software is easier to support since it was built with an industry standard
development tool that ensures engineering test standard.
