Abstract:
1. A fuel-injection system for direct injection of fuel into a combustion chamber through a combustion-chamber top located opposite from a piston, comprising: a fuel injector having a plurality of spray-discharge orifices discharging a corresponding plurality of fuel jets, wherein the plurality of fuel jets form a spray cloud in the combustion chamber; wherein a first opening angle of the spray cloud along a first cross-sectional plane bisecting the longitudinal axis of the fuel injector is greater than a second opening angle of the spray cloud along a second cross-sectional plane bisecting the longitudinal axis of the fuel injector, the second cross-sectional plane extending perpendicular to the first cross-sectional plane, and wherein the first opening angle of the spray cloud along the first cross-sectional plane bisecting the longitudinal axis of the fuel injector and the second opening angle of the spray cloud along the second cross-sectional plane bisecting the longitudinal axis of the fuel injector are symmetrical about the longitudinal axis of the fuel injector.
