SYSTEM FOR IMPROVING EXHAUST GAS PURIFYING PERFORMANCE OF DIESEL HYBRID ELECTRIC VEHICLE |
| 摘要 |
A system for improving exhaust gas purification performance of a diesel hybrid electric vehicle in which an SCR catalyst is equipped in an exhaust line to reduce nitrogen oxide within exhaust gas may include a hybrid control unit configured to request an engine control unit to turn off an engine to make the diesel hybrid electric vehicle enter a hybrid driving mode, and an engine control unit configured to determine whether urea is required to be injected into a front of the SCR catalyst when receiving a request of an engine off from the hybrid control unit. |
