This paper presents a performance Analysis of electrically exhaust gas recirculation valve using commercial electromagnetic simulation software, Flux2D. Under the assumption of 2D axi-symmetric magnetic field, the characteristics of EEGR valve by revising the design parameter, has ken investigated by estimating the variation of thrust force with respect to the pintle position. The mode shapes and the frequency response functions were computed by using three dimensional finite element modeling of the whole EEGR valve and their accuracies were verified with experimental FFT analysis technique.

Usually compound dies are used in clinch washer production. However, in this study, a fine blanking die is designed and manufactured, and clinch washers are produced by the die. Clinch washers are for electric exhaust gas recirculation (EEGR) and they recirculate some of exhaust gas to reduce harmful substances. Fine blanking automation production eliminates difficulties operators face on conventional press.
