TRANSPORT DIESEL ENGINE Russian patent published in 2002 - IPC

FIELD: mechanical engineering; internal combustion engines. SUBSTANCE: invention relates to fuel injection devices of diesel engines. Said transport diesel engine has piston with combustion chamber made in piston, cylinder with head, pump with fuel line, nozzle with spray tip whose axis is tilted relative to axis of combustion chamber. Spray tip has body and shutoff needle. Body is provided with spraying orifices of first group and additionally spraying orifices of second group. Inlet edges of spraying orifices are arranged, respectively, in under-needle space and on locking conical surface. Geometrical axes of orifices of first group form larger angles with spray tip that those of second group orifices. EFFECT: reduced fuel consumption, improved ecological characteristics of diesel engine with combustion chamber with diameter of neck smaller than diameter of combustion chamber. 3 dwg
