The EPA has proposed a rule that would establish ultra-low NOx emissions standards and would implement new certification test procedures for heavy-duty vehicles, driven by the desire to improve accuracy and reduce testing burden on vehicle and engine manufacturers. The new emissions measurement systems will be critical to supporting heavy-duty engine compliance and regulatory development testing programs.
“We are honored to continue the close relationship with the EPA and provide integral solutions as new pressures on reduced greenhouse gas, ultra-low NOx and other criteria emissions are on the horizon for the heavy-duty industry,” said Darren Andrews, executive vice president and general manager, HORIBA Instruments Inc. “The EPA seeks to maintain a facility which is not only best-in-class in both functionality and aesthetics, but also to support future development initiatives now and well into the future. We feel privileged the EPA selected HORIBA to meet those goals.”
To support these initiatives, HORIBA will provide state-of-the-art MEXA-ONE emissions analysis systems to measure both diluted and un-diluted heavy-duty engine exhaust for CO, CO2, THC, CH4, NOx, O2 and NH3. The emissions measurement systems are designed to be used for engines and vehicles with current and emerging fuels and a wide variety of engine aftertreatment technologies. With HORIBA’s STARS Test Automation System automating all aspects of a test based on proven strategies and solutions, the EPA can be confident that the MEXA-ONE and CVS-ONE will continue to meet new requirements due to future-proofing techniques implemented in the design.
HORIBA recognizes that the next decade will be one of unprecedented change in the commercial vehicle industry. Heavy-duty engine and aftertreatment technology will advance rapidly to meet new and pending regulations and these advanced engines may operate in non-traditional ways and present new challenges in terms of emissions testing. HORIBA has designed the MEXA-ONE and the current generation of measurement systems to allow for flexibility necessary to adapt to an evolving test article. By incorporating future-proofing for advanced powertrain technology including the ability to change or add analyzers to an integrated bench system, it improves accuracy and noise performance for ultra-low measurement, expanded dynamic range necessary for diversity of cold and hot duty cycles, and advanced software that allows for synergy with battery emulating equipment and/or road-to-rig testing practices.
The software provided by HORIBA provides numerous functions to increase operational efficiency of automated 1,065 checks and tests, service troubleshooting, as well as improving quality of data through health monitoring and reporting.
