FIELD: machine building.
SUBSTANCE: invention relates to machine building, particularly, to fuel equipment of diesel engines, and can be used to reduce wear of plunger pair of fuel pump. Magnetic field guidance device comprises a pump section housing 1, plunger 3, spring 4, bushing 5, rack rail 7 and plate washer 8. Plunger pair bushing is equipped with holder of permanent magnets 6 rigidly connected with retainer spring 2. When magnetic additive-based anti-wear additive is added to diesel fuel, magnetic field induced in plunger pair controls nanoparticles of additive, wherein nanoparticles are deposited and retained on friction surfaces.
EFFECT: technical result of proposed facility is higher reliability of plunger pair of fuel pump of high pressure diesel engine, prevention of fuel leak through seals due to reduced intensity of wear of plunger pair.
