This paper is to introduce a double closed -loop control strategy, taking the EGR（ exhaust gas recirculation） double closed -loop control as the object of study, with the help of control theories of PID and PWN, and the determination of EGR, hence, the key technology for the determination of EGR is obtained, the EGR rate measuring device （EGR rate sensor） based on nitrogen oxides measurement and the experimental determination method are also taken into their shapes.
