Buffalo, N.Y.-based Global MRV Inc. says its new Firefly emissions testing system is the first onboard device that continuously monitors tailpipe emissions. The system can be adapted for diesel, gasoline and compressed natural gas engines in light- and heavy-duty vehicle applications.
The patented system also is more compact and lighter—measuring 11x11x3 inches and weighing 7 lbs—than current portable monitoring devices used by automotive testing and engineering companies, according to Global MRV. The supplier says it also is considerably less expensive than those systems, which can cost between $80,000 and $250,000.
Unlike competitive monitoring devices that sample emissions during a specified timeframe, the Firefly system continuously measures mass flow emissions. This includes carbon dioxide, oxides of nitrogen, hydrocarbons, carbon monoxide and oxygen. The information is combined with operating data—such as engine load and vehicle speed—and GPS coordinates to enable a comprehensive analysis of emissions performance under varying conditions, the supplier says.
Results are sent to cloud servers and reports can be tailored to customer requirements. In vehicle displays also can be installed if needed.
Global MRV plans to initially target U.S. fleets when it launches Firefly late next year. But the company says it also is exploring global partnerships and talking with several vehicle makers about possible applications.

Mustang Changes for 2018
On Tuesday Ford unveiled—using the social media channels of actor Dwayne Johnson (this has got to unnerve some of the auto buff book editors)—the 2018 Mustang, which has undergone some modifications: under the hood (the 3.7-liter V6 is giving way to a 2.3-liter EcoBoost four, and a 10-speed automatic is available), on the dash (a 12-inch, all-digital LCD screen is available for the dashboard), at the tires (12 wheel choices), on the chassis (MagneRide damper technology is being offered with the Mustang Performance Package), and on the exterior (three new paint colors). And while on the subject of the exterior, there are some notable changes—a lower, remodeled hood, repositioned hood vents, new upper and lower front grilles, LED front lights, revised LED taillamps, new rear bumper and fascia.
