66 -- ACQUISITION OF ELECTRIC DYNAMOMETER TEST SYSTEM FOR SMALL AND LIGHT DUTY ENGINE TESTING SOL C600638T1 POC Contact Point, Cynthia Johnson, (513)366-2040, Contracting Officer, Lisa Stultz, (513)366-2041 Solicitation: C600638T1. The US EPA, National Vehicle and Fuel Emissions Laboratory seeks to obtain an engine dynamometer test system (EDTS) comprised of several component subsystems - an engine dynamometer test stand and control system, a data acquisition and test process control system, a combustion cycle analysis system, and other required auxiliary test equipment. EPA will initially use the EDTS to expand suppport for the PNGV 4-Stroke, Direct Injection Technical Team. These test systems will also support ongoing efforts to reduce NOx and Particulate emissions from on and off-road diesel engines. The dynamometer, its test stand, and the auxiliary systems are the major mechanical hardware components of the EDT. The dynamometer is an AC variable frequency motor-absorber and is to be controlled by a computer as part of a test system that utilizes a flexible test definition and control process which can be interfaced with a combustion cycle analysis system and a data acquisition and analysis system, and integrates other auxiliary measurement systems to support the EDTS test processes. Ambient conditions, test parameter measurements, and exhaust emissions sampling must also be recorded by the computer system. The contractor is responsible for the proposal, design, fabrication, installation, and commissioning of the total system. The contractor is responsbible for integrating the engine/dyno signals (load, speed, throttle, and feedback measurements) with the test process control and data acquisition system and test process control algorithms. The test process computer operator interface(s) must be easy to use, and must provide the system features and capabilities in a manner that is flexible and adaptable for configuring, defining, executing, recording, analyzing, storing, and reporting any test sequence and configuration that may be defined by the user. The EDTS must be configured to easily facilitate the integration of other subsystems through the use of standard computer interfaces and communication protocols. The Government anticipates the award of a two year, fixed price, indefinite delivery, indefinitie quantity contract for up to a total of 20 of the individual systems noted. The SOW provides the technical and functional specifications for the procurement, acceptance tests, installation requirements, commissioning tests that shall be performed by the contractor. All responsible sources may submit a response which, if timely, will be evaluated by the Agency. All request for a copy of the solicitation must be in writing. No telephone requests will be honored.
