HORIBA develops new PEMS to meet new Euro 7 legislation

|   Press Release

The HORIBA QCL-IR PEMS is based on the proven IRLAM technology and will measure up to 8 components with high accuracy in a single unit to meet the new Euro 7 demands.

Oberursel, Germany – HORIBA, a leading supplier of automotive test systems, introduces the HORIBA QCL-IR (Quantum cascade laser infrared spectroscopy) Portable Emissions Measurement System (PEMS) designed for on-board measurement in light-, heavy-duty and non-road-mobile-machinery. In response to the emphasis on on-road RDE (real driving emissions) measurement in the Euro 7 legislation proposal, HORIBA leverages its extensive PEMS expertise to deliver a compact, user-friendly, robust, and precise system capable of measuring up to 8 components simultaneously.

HORIBA has anticipated the need for future-proofed technology, the system provides compatibility with the proposed LDV and HDV applications as outlined in the current Euro 7 proposal. The HORIBA QCL-IR PEMS is therefore equipped to measure CO, CO2, NO, NO2, but also NH3, N2O, HCHO and CH4. A FID for total hydrocarbon measurement is also included.

The system incorporates HORIBA's proprietary Infrared Laser Absorption Modulation (IRLAM™) technology. IRLAM™ not only allows for exceptional accuracy but also enables the system to maintain its precision across various operating conditions, including vibration, temperature, and altitude, while remaining compact in size.

IRLAM™ has already been successfully deployed in HORIBA's OBS-ONE-XL01 for on-board emissions measurement, as well as in stationary emission testing solutions such as the MEXA-ONE XL-NX or XLA series. This advanced technology enables real-time measurement of gases that were traditionally challenging to assess using conventional infrared gas analysis techniques (such as NDIR and FTIR) due to sensitivity limitations and interference and vibration effects. IRLAM™ represents the next milestone in HORIBA's refined infrared gas analysis technology, offering high sensitivity, minimal interference, exceptional reliability, and seamless installation. It serves as the core analysis technology for HORIBA's suite of solutions.

“The upcoming Euro 7 legislation will not only add new testing areas such as batteries or non-exhaust emissions, but also tighten the prior emission standards”, explains Matthias Schröder, Technical Director at HORIBA Europe GmbH. “The QCL-IR is one of HORIBAs cornerstone solutions in our ambition to be a trusted partner for testing solutions in the industry and to support our customers to adhere to the current and upcoming Euro 7 legislation.”

HORIBA is expecting to make the new HORIBA QCL-IR PEMS available within the first half of 2024.
