| Abstract(E) | A vehicle-mounted measurement system (SEMS) which included sensors such as NOx sensor and NH3 sensor directly inserted into the exhaust pipe was installed on a heavy-duty diesel vehicle that complies with the 2016 exhaust gas regulations. Then, we acquired the data in the transportation business driving. Based on these data, the NOx purification rate, space velocity, etc. were analyzed as the parameters to investigate the NOx purification performance of the Cu-based zeolite SCR catalyst. As an example, during DPF regeneration, the purification rate gradually decreased to about 40% due to the oxidation of NH3 in the process of temperature rise. |
