| 초록 |
To establish NOx Storage Reduction(NSR) system, the effect of post fuel injection in exhaust pipe with rich spike on NOx conversion rate was investigated. With post fuel injection, a higher injection pressure and the rich spike close to the NSR catalyst) shows better NOx reduction performance. Based on these results, exhaust emission was tested in transient driving mode (JE-05). In this driving mode test, it was possible to reduce NOx emission less than 0.5g/kWh for only a 1% of fuel penalty controlling the rich spike injection precisely. |
