Good Agreement

As Future emission limits of diesel engines is more stringent, model-based control strategy of selective catalytic reduction (SCR) is becoming necessary. Therefore, a catalytic converter mathematical model for simulating selective catalytic deNOx reaction is very important. In this paper, a one dimension catalytic converter mathematical model that consists of thermal energy model, SCR reaction model and NH3storage model for simulating urea-SCR reaction process is presented. Based on this model, the impact of temperature and gas hourly space velocity (GHSV) on NOx conversion efficiency has been researched. According to the results of simulation, it shows good agreement with experimental data.

This paper presents the experimental studies on an SCR system for a mobile heavy-duty diesel engine to reduce NOx emission below Euro V emission limits. The test results obtained by one engine serving in China show that NOx emission was reduced to 1.81 g/kWh with ESC and 1.66 g/kWh with ETC, the reduction efficiency of NOx was reduced by about 80%, while the average NH3 slip is kept below 6 ppm.
