I haven't found anything which definitively states one way or the other on the EGR valve for SKYACTIV-G technology. What I can tell you is the purpose of the EGR and because of that why the technology itself would not cause the demise of the EGR. EGR or Exhaust Gas Recirculation is a technology which was introduced to limit temperatures during combustion. ...
