Global MRV introduces first permanently embedded Micro PEMS for continuous onboard emissions analysis
Global MRV, a provider of portable emissions measurement systems (PEMS), has introduced the first on-board permanently embedded Micro PEMS that reports all regulated vehicle emissions and performance system data all the time. Called Firefly, the PEMS provides continuous analysis of diesel or internal combustion engine emissions. The patented Firefly unit is 11-inches long by 11-inches wide and 3-inches high, and weighs seven pounds (3.2 kg).
Global MRV is deploying Firefly technology to measure, report and verify the operations of light- and heavy-duty vehicles operating in normal driving conditions. Firefly collects and allows for the combined analysis of engine, GPS and emissions data; the unit is currently being tested in on-road vehicles and will be available to the market at the end of 2016.
Making sure vehicles meet their performance and emissions claims is a priority for both government regulators and fleet operators, but expensive lab testing only allows for selective sampling. Firefly technology will transform the world of emissions monitoring by providing real driving emissions data in real time, to the cloud, allowing a whole new level of data monitoring that can instantly show if and when a vehicle’s emissions increase beyond legal targets. By providing reliable emissions and performance data, operators can optimize their vehicles, improving their bottom line, while society benefits from the knowledge that emissions targets are being met.—David Munro, CEO Global MRV
Firefly measures mass flow emissions of CO, CO2, NOx, HC, and O2 in real time, while simultaneously collecting and combining electronic control unit (ECU) and GPS data that provides:
- Accurate and timely data for informed decision-making
- Large fleet data set collection
- Minimal set-up time
- Rapid deployment
- Data availability in a ready-to-use format
- Pre-configured formats
- User-defined formats for customized reports
The flexibility of Firefly proprietary software allows emissions data to be translated into grams per miles, gallons, kilometers, etc., depending on the application.
Patented indirect exhaust flow measurement provides accurate PEMS flow data. On-board engine information is captured and aligned with engine computer link hardware and software.
