Kind Code:
A1
Abstract:
A fuel injection device and a parameter calibration method for the fuel injection device. The fuel injection device comprises a first fuel injector (1) and a second fuel injector (2), wherein both the first fuel injector (1) and the second fuel injector (2) are obliquely provided on a cylinder head (100); the first fuel injector (1) comprises a first fuel nozzle (11); the first fuel nozzle (11) is located in a combustion chamber (200); a plurality of first fuel injection holes are formed in the circumferential direction of the first fuel nozzle (11), so as to facilitate injection of fuel beams to the edge area of the combustion chamber (200); the second fuel injector (2) comprises a second fuel nozzle (21); the second fuel nozzle (21) is located in the combustion chamber (200); second fuel injection holes and third fuel injection holes are formed on the second fuel nozzle (21); the second fuel injection holes face the central area of the combustion chamber (200), so that the fuel beams sprayed from the second fuel nozzle (21) are directed towards the central area of the combustion chamber (200); and the third fuel injection holes face annular protrusions (201) in the combustion chamber (200), such that the fuel beams sprayed from the second fuel nozzle (21) are directed towards the annular protrusions of the combustion chamber (200).
