CATALYST LIGHT-OFF TIME REDUCTION AND MAINTENANCE |
| 摘要 |
A fast light-off time enhancement device and method may be used for an exhaust catalyst or particulate filter. The light-off time enhancement device may include a fuel injector, a carbon nano-tube injector, and a light source when active may generate heat. Heat generated thereby provides improving light-off time of the catalyst. Additionally, the same system may be used to generate heat to regenerate a particulate filter. An associated control system may be utilized to monitor vehicle parameters and determine the appropriate use of the light-off enhancement device. |
