SEMS operating as a proven system for screening real-world NOx and NH3 emissions
conference paper
NOx emissions of heavy-duty and light-duty diesel vehicles depend strongly on the driving conditions. The introduction of combined emission reduction technologies in Euro VI vehicles have demonstrated that NOx emissions become less predictable when the data is based on relatively short test cycles. Due to the decreased predictability with the increased complexity of the after-treatment technology, emission measurement over longer periods of testing time is required. Commissioned by the Dutch Ministry of Infrastructure and the Environment, TNO recently started the development of a simple, robust and low-cost emission screening tool called SEMS (Smart Emission Measurement System). The system is able to perform NOx and NH3, or ammonia, emission measurements as a stand-alone system for periods of over a week.
