摘要： An exhaust gas recirculation device for nitrogen oxide reduction is provided to suppress generation of the nitric oxide effectively because the EGR valve is opened when intake air volume satisfies the valve opening condition, compared with the current RPM. An exhaust gas recirculation device for nitrogen oxide reduction comprises a EGR(Exhaust Gas Regulation) valve(12), a flow sensor(13), an RPM(Revolution Per Minute) sensor(14), and an EGR control unit(15). The EGR valve is installed at the inlet of a cooling device(11). The EGR valve controls the inflow of the exhaust. The flow sensor is installed at the intake hole of an engine(1). The flow sensor includes the exhaust inflowing through the cooling device to measure the intake air volume[kg/h] of the gas inflowing into the engine. The RPM sensor is installed in the engine. The EGR control unit sets up the valve opening condition, compared with the RPM, based on plural operation modes. The plural operation modes are selected on the standard test mode for exhaust measurement to the engine.
