Horiba receives test equipment contracts from the US EPA

7 August 2003

Ann Arbor, MI-based Horiba Instruments’ Engine Measurement Division was awarded a contract from the US EPA’s National Risk Management Research Laboratory (NRMRL) to supply and install a heavy-duty diesel (HDD) emissions sampling system with SAO-based (Smooth Approach Orifice calibration venturi) flow control. The system complies with EPA’s 2007 on-highway testing standards and will be used to evaluate transient emissions testing on HDD vehicles. The installation will be at NRMRL’s Truck Dynamometer facility, located in Research Triangle Park, NC.

The announcement follows EPA’s award to Horiba, in July 2003, for three complete chassis emission test sites at the National Vehicle and Fuel Emission Laboratory (NVFEL) located in Ann Arbor, Michigan. The new systems at NVFEL will be dedicated to certifying passenger vehicles under EPA’s coming Tier 2 standards that apply to both gasoline and diesel-fueled cars and light-duty trucks. Horiba will provide turn-key emission test systems that include a full complement of analytical benches, sample dilution and particulate sampling equipment, and test control systems. The contract includes three Horiba bag mini-diluter (BMD) systems, marking the first use of BMD technology by EPA for certifying vehicles. Installation will be in test cells D002, D005 and D329, which is currently under construction.
