Method of removing nitrogen oxides in exhaust gases from a diesel engine |
摘要 |
<p>The present invention concerns a method of removing nitrogen oxides in exhaust gasses from a diesel engine (1) by using a catalyst in a reactor (10) under the presence of ammonia, wherein a humidity of intake air as a specific factor and one or more of engine power, fuel consumption amount of engine, temperature of engine intake air and exhaust gas temperature as selective factors are measured respectively as the measuring factors and the flow rate of ammonia is controlled based on measured values and ammonia is supplied to an exhaust gas flow channel (11) from the engine (1) to the reactor (10).</p> |
