Injector 3022197, also listed as 3022197-20 and 3022197-28, is the upgraded PT-D fuel injector assembly for Cummins K19, KTA19 and QSK19 engines. The high-strength alloy steel body uses combined FKM and nitrile sealing rings around a plunger, spring and nozzle assembly, running on a supply pressure of 0.69–2.07 MPa. It installs vertically in the cylinder head with the spring top against the cam follower.
