portable emissions measurement system
Introduction. Portable Emissions Measurement Systems, or PEMS, measure emissions from combustion engines as the vehicle or the equipment is being used, which allows real-world in-use testing. PEMS offer a modern and innovative counterpart to check the impact of emissions from combustion engines upon the environment.
Compact Portable Emission Measurement Systems PEMS (Portable Emission Measurement System) / RDE (Real Driving Emissions) A probe delivers the vehicle exhaust gases from the test box in real-time mode. The component emissions (CO, CO 2, NO X [oder NO + NO 2 ]) together with the associated engine, vehicle and environmental parameters are then recorded for analysis.
Portable Emissions Measurement Systems (PEMS) Sensors’ SEMTECH® product line goes wherever your vehicles go, for real-world emissions and fuel economy testing. SEMTECH® products are easy-to-install, easy-to-use, extremely rugged, and offer fast and accurate results.
LIGHT-DUTY PORTABLE EMISSIONS MEASUREMENT SYSTEMS. The SEMTECH® Light-Duty portable emissions measurement systems are designed to meet worldwide regulatory standards in a package that installs to a wide range of light-duty vehicles quickly and easily. Modules are designed to work with each other, with minimal connections, or to work as standalone units.
A portable emissions measurement system (PEMS) is a vehicle emissions testing device that is small and light enough to be carried inside or moved with a motor vehicle that is being driven during testing, rather than on the stationary rollers of a dynamometer that only simulates real-world driving.
The PEMS utilizes the AVL M.O.V.E. system for gaseous emission measurements and the AVL 494 system for PM measurements. The AVL M.O.V.E. is equipped with a non-dispersive ultraviolet (NDUV) analyzer for measuring oxides of nitrogen (NO and NO2), a non-dispersive infrared (NDIR) analyzer for measuring CO and CO2, and a flame ionization detector
