SPRAYER FOR DIESEL INJECTOR Russian patent published in 2020 - IPC F02M61/10 F02M61/18 

FIELD: engine building.

SUBSTANCE: invention relates to propulsion engineering and can be used in diesel engines. Sprayer for diesel injector comprises housing 12 with locking needle 13, sub-needle volume 14, spraying holes 15, 16, input edges of which are located in sub-needle volume 14. According to invention outlet edges of spraying holes are arranged uniformly in plane perpendicular to central axis of combustion chamber, and axes of holes form angle of "tent" of spraying γ_sp, which is deviated from sprayer axis by angle γ. Hole axes are deviated from sprayer axis by angle β₁, which is equal to angle (γ_sp/2) – γ, and at angle β₂, equal to angle (γ_sp/2)+γ. Angle β₁ is less than angle β₂. Diameter of hole arranged at angle β₁, less than diameter of hole arranged at angle β₂.

EFFECT: technical task of the invention is aimed at improving the quality of mixture formation and combustion in a single symmetric combustion chamber of a transport diesel engine with a storage fuel apparatus at an inclined position of the nozzle relative to the axis of the cylinder and a central position of the nozzle tip in the combustion chamber.
