According HC trap catalyst application, engine and vehicle's emission characteristics are changed. Especailly CO, NOx, NMOG were changed significantly depend on regulation. Vehicle catalysts reduce performance incerasing vehicle mileages. We performed fast aging cycle at engine test bench. And we evaluated sample performance test at engine test bench and performed regulation test(FTP-75 mode) at chassis test bench. In SULEV30 regulation, it's difficult to meet NMOG+NOx target. Applying HC trap catalyst, get the more benefit of NMOG+NOx but CO emission increaes slightly. We expect to meet more easier SULEV30 regulation as a result of applying HC trap catalyst. |
