Abstract
PURPOSE:To enhance efficiency of removing NOX by calculating a flow amount of NH3 gas in accordance with an engine load or the like to be corrected in accordance with a deviation of NOX concentration, in the case of an engine in which the NOX in exhaust gas is removed by blowing the NH3 (ammonia) gas into the exhaust gas. CONSTITUTION:An NH3 gas flow quantity signal Q1, corresponding to a generator output signal KW from a generator driven by an engine, is output from an input processor 9. While detecting NOX concentration in exhaust gas of the engine by a NOX analyzer, a NOX concentration signal from the NOX analyzer is input to a comparator 11 with an output signal from a NOX concentration setter 10, and a deviation signal of the comparator is output to a PID arithmetic device 12 only when the above described flow quantity signal Q1 exceeds the predetermined lower limit value Q0. The obtained flow quantity correction signal Q is fed to a corrector 13. In this corrector 13, adding the above described flow quantity signal Q1 to the flow quantity correction signal Q, a flow quantity signal Q2 after correction by this addition is output to a flow regulator of NH3 gas through a signal regulator 14.
