66 -- VEHICLE EMISSIONS, ELECTRIC DYNAMOMETERS, TEST SYSTEMS SOL 98-15 POC Pam Legare (513)487-2015 E-MAIL: U.S. EPA -- Cincinnati Contracts Management Division, legare.pamela@epamail.epa.gov. The U.S. Environmental Protection Agency (EPA)seeks experience vendors who can provide an upgrade to an existing Horiba Light Duty (LDV) 48" single roll electric dynamometer to have Medium Duty Vehicle (MDV) load capabilities for use in motor vehicle emissions testing in accordance with CFR Part 40 Subpart 86. This procurement will provide two essential components of this retrofit -- the physical hardware and software changes and the expertise to engineer, install, calibrate, and verify the complete system. The physical changes involve a new AC flux vectored power converter and drive to enable higher loading capability. Three phase wiring from the power panel to the dynamometer disconnect and power converter will need to be replaced to handle the higher electrical current loads (250 amps) of MDV dynamometer. The existing motor, load cell, rollers, and all mechanical components of the LDV-48 machine can be retained, but the upgraded system will require a new calibration and parameter changes to adjust the response tuning after the electrical power upgrade. The subsystems shall be installed and integrated with the existing Horiba RTM-200, microcomputer and CDC 900 controller systems that control the performance of the dynamometer. Any parameter or software changes shall be completed by the vendor and the performance of the overall system shall be verified by an acceptance test procedure. Interested parties should submit a written request to Pam Legare at the above address, by fax (513)487-2015 or by e-mail (legare.pamela@epamail.epa.gov). TELEPHONE REQUESTS WILL NOT BE HONORED. The request for proposal is scheduled to be issued fifteen days after the date this synopsis is published. Posted 07/27/98 (W-SN228778). (0208)
