ENGINE CONTROLLER AND METHODS FOR CONTROLLING EMISSION AND POWER GENERATION SYSTEM USING THE SAME |
| 摘要 |
A method for controlling an emission amount in an exhaust gas stream emitted from a power generation system is presented. The method includes determining a pre-catalyst emission level using a combustion engine model. The method further includes determining a post-catalyst emission level using a three-way catalyst model based on the pre-catalyst emission level. Furthermore, the method includes determining an adjusted post-catalyst emission level based on the post-catalyst emission level. Moreover, the method includes determining a difference between the post-catalyst emission level and the adjusted post-catalyst emission level and comparing the difference with a threshold value. Additionally, the method includes determining whether to adjust an actual value of an engine operating parameter based on the comparison such that the emission amount in the exhaust gas stream is maintained below an emission regulatory limit. An engine controller and a power generation system employing the method are also presented. |

1. A method for controlling an emission amount in a gas stream emitted from a power generation system comprising a combustion engine operating at stoichiometric conditions, and a three-way catalyst disposed downstream of the combustion engine, the method comprising:
determining a pre-catalyst emission level using a combustion engine model; determining a post-catalyst emission level using a three-way catalyst model based on the pre-catalyst emission level; determining an adjusted post-catalyst emission level based on the post-catalyst emission level; determining a difference between the post-catalyst emission level and the adjusted post-catalyst emission level and comparing the difference with a threshold value; and determining whether to adjust an actual value of an engine operating parameter based on the comparison such that the emission amount in the gas stream is maintained below an emission regulatory limit. |
