CUBIC INSTRUMENTS Gasboard-9805 Portable Emission Measurement System (PEMS) for On-Road Vehicles

Overview

The CUBIC INSTRUMENTS Gasboard-9805 is a fully integrated, portable emission measurement system (PEMS) engineered for real-world driving emissions (RDE) testing of light-duty and heavy-duty on-road vehicles. Designed in strict alignment with global regulatory frameworks—including EU Regulation (EU) 2016/427, (EU) 2017/1151, U.S. EPA 40 CFR Part 1065, and China’s GB 18352.6–2016—the system delivers continuous, time-synchronized measurement of gaseous pollutants (CO, CO₂, NO, NO₂, NOₓ, O₂, THC), particulate number (PN), exhaust mass flow, ambient meteorological parameters, GPS-derived vehicle kinematics, and standardized OBD data streams. Its core architecture employs industry-validated physical detection principles: non-dispersive infrared (NDIR) for CO and CO₂; non-dispersive ultraviolet (NDUV) for NO and NO₂; flame ionization detection (HFID) for total hydrocarbons (THC); electrochemical or tunable diode laser absorption spectroscopy (TDLAS) for NH₃ and N₂O; and corona-based particle charging coupled with condensation particle counting (CPC) for PN down to 10 nm. All subsystems are synchronized via a central high-resolution timestamp engine (10 ms resolution), ensuring traceable, audit-ready data acquisition compliant with ISO 26262 functional safety guidelines for measurement integrity.

Key Features

• Modular, plug-and-play hardware architecture enabling rapid reconfiguration for diverse test cycles—RDE, WLTC, FTP-75, or custom R&D protocols.
• Integrated lithium-ion battery pack delivering ≥8 hours of continuous operation under full sensor load and GPS logging—no external power required during transient road testing.
• Ruggedized IP65-rated enclosure with shock-absorbing mounting brackets and thermal management optimized for sustained operation across −10 °C to 45 °C ambient conditions and up to 3000 m altitude.
• Real-time onboard calculation of cumulative mass emissions (g/km, g/test), instantaneous specific emissions (g/s), and conformity factors (CF) per UN R155 and EU RDE requirements.
• Automated calibration verification routines with built-in span/zero gas check capability—supporting daily pre-test verification without external equipment.
• Embedded firmware with configurable data logging intervals (100 ms to 1 s), dual SD card redundancy, and encrypted local storage meeting ISO/IEC 27001-aligned data protection standards.

Sample Compatibility & Compliance

The Gasboard-9805 supports direct sampling from raw exhaust ducts (pre-catalyst or post-catalyst), diluted exhaust tunnels (e.g., CVS integration), and tailpipe probes conforming to SAE J2945/1 and ISO 20884 mechanical interface specifications. All gas analyzers comply with EN 14181 QA/QC requirements for automated monitoring systems, while PN measurement meets PMP (Particle Measurement Programme) recommendations for 10 nm cut-point validation. The system satisfies data integrity prerequisites for regulatory submission under EU Commission Regulation (EU) No 1014/2010 (RDE reporting format), U.S. EPA 40 CFR Part 1065 Subpart D (data recording), and China’s CNAS-CL01:2018 accreditation criteria. Full audit trails—including operator ID, calibration history, environmental metadata, and firmware version logs—are retained with tamper-evident timestamps to support GLP/GMP and ISO/IEC 17025 laboratory accreditation.

Software & Data Management

The proprietary Gasboard Control Suite (v4.2+) provides a Windows-based interface for test configuration, real-time visualization, and post-processing. It supports automatic mapping of GPS trajectories onto digital elevation models (DEM), dynamic correction of exhaust flow using intake air mass and dilution ratio algorithms, and statistical filtering per ISO 16183 for outlier rejection. Raw binary data (.gbd format) exports natively to CSV, MAT, and AVL PUMA-compatible formats. The software implements role-based access control (RBAC), electronic signatures, and 21 CFR Part 11-compliant audit trail generation—including user actions, parameter changes, and report approvals—with SHA-256 hashing for data immutability. Cloud synchronization (optional) enables secure remote data review via TLS 1.3–encrypted API endpoints.

Applications

• Regulatory certification testing for Euro 7, U.S. Tier 3, and China VIb compliance.
• In-use conformity (IUC) audits conducted by national type-approval authorities and independent testing laboratories.
• Powertrain development—optimizing aftertreatment control strategies under real-world transients.
• Fleet emissions monitoring for municipal bus operators, logistics providers, and government vehicle programs.
• Academic research on cold-start emissions, urban canyon effects, and low-speed NOₓ formation mechanisms.
• Verification of retrofit device performance (e.g., SCR, GPF, LNT) under actual operating conditions.

FAQ

Does the Gasboard-9805 meet EU RDE Type Approval requirements for homologation testing?
Yes—it fulfills all technical specifications defined in Annex II of (EU) 2017/1151, including PN measurement uncertainty <±25%, gaseous analyzer accuracy tolerances, and mandatory data synchronization protocols.
Can the system be used for both light-duty passenger cars and heavy-duty trucks?
Yes—exhaust flow modules support scalable ranges (10–600 kg/h and 100–2000 kg/h), and mounting kits include OEM-specific adapters for chassis rails, trailer hitches, and roof racks.
Is third-party calibration certificate included with delivery?
Each unit ships with a factory calibration report traceable to NIST and NIM standards, plus a 12-month calibration validity period. Optional annual recalibration services are available through CUBIC’s ISO/IEC 17025-accredited service centers.
How is data security ensured during field deployment?
All stored data are AES-256 encrypted at rest; communication channels use TLS 1.3; and firmware updates require signed digital certificates verified against CUBIC’s root CA.
What is the minimum detectable particle size for PN measurement?
The system offers dual-cutpoint configurations: 10 nm (PMP-compliant) or 23 nm (for legacy fleet evaluation), selectable via software-defined instrument configuration.
