Horiba awarded EPA contract for HD engine emission test equipment

5 December 2003

Ann Arbor, MI-based Horiba Instruments, Inc.has been awarded a contract to equip two heavy-duty engine test sites at the EPA National Vehicle and Fuel Emissions Laboratory (NVFEL) in Ann Arbor, MI. The Horiba-equipped test sites, scheduled to be complete in 2004, will allow EPA to measure emissions from spark ignition and diesel engines that comply with future emission standards for highway and nonroad applications.

Horiba will supply a complete gaseous and particulate measurement system for EPA’s new Heavy-Duty Cell 5 (HD5), located in rooms 423 and 425 at NVFEL. Among the equipment specified for HD5 is a full flow dilution tunnel with particulate sampler, CVS emissions sampling system, and MEXA-7000 analytical systems capable of bag/continuous-dilute and raw emission measurement. Horiba will also supply new MEXA-7000 analytical systems to upgrade Heavy-Duty Cell 2 (HD2), located in room 415 at NVFEL. Horiba will have complete system responsibility for the design, installation, and commissioning of the emissions test equipment.

EPA plans to use the newly equipped HD5 test cell to conduct emissions certification testing and evaluate experimental engine technology. The primary focus for HD2 will be to evaluate new testing methods in support of the 2007 heavy-duty on-highway emissions standards.

This award follows recent Horiba contracts to supply light-duty vehicle emission test equipment for the NVFEL lab, and a heavy-duty emissions sampling system to the EPA NRMRL laboratory in Research Triangle Park, NC.
