#CMT# #/CMT# The nozzle has a nozzle needle directed into a nozzle body and opened against fuel flow direction, where injection cross-section of the needle is controllable based on stroke. A needle head is provided at combustion chamber side ends of the nozzle needle, and has a control element in the flow direction on a conical valve seal seat of the nozzle body for controlling a leakage profile. The injection cross-section of the needle is varied in size and shape based on the needle stroke. #CMT#USE : #/CMT# Fuel injection nozzle for an internal combustion engine e.g. diesel engine and petrol engine. #CMT#ADVANTAGE : #/CMT# The needle head has the control element in the flow direction on the conical valve seal seat of the nozzle body for controlling the leakage profile, and the injection cross-section of the needle is varied in size and shape based on the needle stroke, thus ensuring optimal stable jet formation for idle load, partial load and full load operations without carbonization danger, and reducing clearance volume while improving performance and smoothness of the engine, and minimizing fuel consumption and exhaust gas emission. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a partial longitudinal sectional view of a fuel injection nozzle cone.'(Drawing includes non-English language text)'. |
