Study on the ESC Steady-State Cycle Experiments of SCR System for Reducing NOx Emissions

Abstract:

In this paper we mainly use the SCR system to do some ESC experiments for reducing NOx emissions. The main purpose of the experiments is to improve the ability of SCR system to reduce NOx emissions. The main research works are focused on the following aspects: First we could get the NOx emissions content for original machine and the theoretical demand content for urea by the emission experiment of original machine. Then on the condition of SCR catalyst is not installed, we could get the NOx emissions content by injecting a certain amount of urea. Based on the above experiments we could get the experimental results for NOx emissions by installing SCR catalyst and using the DCU to control urea injecting.
