HORIBA prepares customers for new emissions testing with OBS-ONE

27 septembre 2017


Since September, real driving emissions (RDE) demand new requirements and testing procedures. As the worldwide leading supplier of emission test systems, HORIBA is well prepared and introduces a new portable emissions measurement system (PEMS) as a direct response to new requirements and testing procedures for certifying passenger cars and light commercial vehicles.

The modular on-board emissions measurement system enables testing procedures in real-world driving conditions.

Natalie Baltes, European Product Manager of OBS-ONE, stresses HORIBA’s self-perception as a reliable Partner for their customers: „We designed the OBS-ONE Series to support our customers while adjusting to the new requirements, providing an easy to install, safe and accurate solution, which allows stable operation over long driving periods.“

The OBS-ONE series measures concentrations of emissions, particulate matter, particle number, exhaust flow rate, monitors GPS data and environmental conditions and calculates mass emissions. The three main products comprise the OBS-ONE-GAS (Gas), OBS-ONE-PN (Particle Number) and OBS-ONE-PM (Particulate Matter) units. The OBS-ONE gas analysis unit enables hot and wet based measurement of the gaseous components CO, CO2, NO, NOx and total hydrocarbons (THC). With the new MA unit, the OBS-ONE gas analysis unit now also measures methane (CH4).

Another benefit of the series comprises exchange and convertibility of all modules which makes the OBS-ONE series highly adaptable for different applications depending on the customers’ needs.

Easy to use features allow all-in-one measurement processes

The total OBS-ONE system for regulation compliance, engine and vehicle research furthermore comprises a comprehensive test package which includes the features self-diagnosis, quality check and calibration before testing.

During the test, the system monitors a variety of environmental variables such as ambient temperature and humidity. It automatically calculates the corresponding mass emissions of the regulated exhaust gases. As the system checks measuring data during the testing process in real time, invalid test results are mitigated and accurate measurement is ensured.

The new series not only simplifies measurement and ensures safety as drivers can concentrate on driving without any operation; it also streamlines data post processing. Displaying the camera-recorded drive replay and a GPS map related to the measured data, OBS-ONE simplifies the complicated process of calculation and analysis and creates test reports for certification complying with latest legislation requirements.

The system furthermore comprises the highly adaptable, intelligent and intuitive operating platform HORIBA ONE PLATFORM which gives customers complete system control and view due to showing all measurements taken with OBS-ONE units on one single display.

The complete portfolio is not only suitable for RDE testing of passenger cars, light and heavy duty vehicles but also applicable for non-road mobile machinery (NRMM) which will be subject to certification in the near future. With the OBS-ONE series, HORIBA has taken action to actively support companies during the transition from classic test bed models to RDE-compliant measurements.
