FIELD: engine building.
SUBSTANCE: fuel injector (26) for internal combustion engine (10) comprises injector head (28) comprising nozzle (44), preliminary mixing device (48) and distributor (70), adapted for distribution of several different types of fuel into different sets of passes (58, 60, 66) for fuel supply in device (48) of preliminary mixing. Unit (103) of pilot injection of fuel injector (26) is connected to device (48) of preliminary mixing and comprises first fuel feed path (110) for first fuel and second fuel feed path (111) for second fuel. Several sets of passes (58, 60, 66) for fuel supply are located in fuel injector (26), wherein sets (58, 60, 66) of passages for fuel supply are selectively connected to several sources (20, 22, 24) of different fuel, and both, both have such location and size, to correspond to wide range of fuel consumption to provide operation of internal combustion engine (10) connected to fuel injector (26), on fuel having Wobbe number range and compositions.
EFFECT: invention discloses a fuel injector and a fuel system for an internal combustion engine.
