A method of removing nitrogen oxides in exhaust gases from a diesel engine, comprising the steps of: using a catalyst in a reactor under the presence of ammonia, measuring in-take air humidity as a specific measuring factor and at least one of engine power, fuel consumption, engine in-take air temperature and exhaust gas temperature as other measuring factors, controlling the flow rate of ammonia based on said measured factors, and supplying said controlled flow of ammonia into an exhaust gas flow channel from the engine to the reactor.
