OPERATION EXHAUST GAS RECIRCULATIONA. General information
In USA version starting model year 1980 for California and starting model year 1981 for Federal and California, engine 617.95 is provided with exhaust gas recirculation (EGR).
To reduce nitric oxides in exhaust gases, a portion of the exhaust gases is returned from exhaust manifold to intake manifold by means of a valve.
