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 (just before 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 0.5 g/kWh for only a 1% of fuel penalty controlling the rich spike injection precisely.
