/ 161 PORTABLE MEASURING SYSTEM FOR GASEOUS EMISSIONS AVL M.O.V.E GAS PEMS APPLICATION • Internal climate concept for accurate measurements in a wide ambient temperature range and under changing ambient conditions • Robust against vibration through internal dampers and external damping options • High measurement accuracy even in a low measurement range • Low span and zero drift for long measurement intervals • Special “Hybernate” mode to reduce warm-up time BENEFITS AT A GLANCE • Internal climate concept for accurate measurements in a wide ambient temperature range and under changing ambient conditions • Robust against vibration through internal dampers and external damping options • High measurement accuracy even in the low measurement range • Low span and zero drift for long measurement intervals • Special “Hybernate” mode to reduce warm-up time Measurements with portable emission measurement systems (PEMS) on the road are an efficient way to keep the development effort at a reasonable level even if the requirements for fuel economy, emissions and customer expectations are increasing. PEMS systems are also needed for in-use compliance testing where heavy duty vehicle manufacturers have to report compliance with emission standards. Such measurements require robust and compact devices which are able to withstand the rough testing conditions and which provide reliable and accurate measurements over long test durations and under changing ambient conditions. MEASUREMENT PRINCIPLE The AVL GAS PEMS is a compact and robust PEMS system for measuring the THC, NO/NO2 and CO/CO2 concentrations in the exhaust gas of diesel and gasoline vehicles and engines. High measurement accuracy is achieved through the use of reliable test cell analyzers which are optimized for the mobile application. All analyzers are temperature conditioned to ensure reliable measurements even at changing ambient conditions. The GAS PEMS is controlled via AVL M.O.V.E System Control, which stores the data, calculates the online emissions and provides interfaces to access e.g. ECU/CAN bus data and additional sensors.
