<p>An exhaust gas recirculating system forming an exhaust gas recirculating engine capable of stably, properly, and safely reducing harmful substances by controlling the EGR rate or the content of NOx in exhaust gas of an EGR engine, comprising circulating lines (11-1) to (11-5) for recirculating the exhaust gas therein, a scrubber (21) for cleaning the exhaust gas, a recirculating exhaust gas flow sensor (114) for measuring the flow of the recirculating exhaust gas, a mixed gas flowmeter (125) for metering the flow of the mixed gas formed of the recirculating exhaust gas and the external air fed to the engine, an engine speed sensor (124) for measuring the speed of the engine, and a control part (110) for controlling the flow of the recirculating exhaust gas based on the flow of the recirculating exhaust gas metered by the recirculating exhaust gas flow sensor (114), the flow of the mixed gas metered by the mixed gas flowmeter (125), and the engine speed measured by the engine speed sensor (124).</p> |
