Perfection of fuel atomization by increasing injection pressure required for compliance of diesel engines with increasingly restrictive ecological standards related to toxic emissions is associated with the increase of power for high pressure fuel pump drive and decrease of the nozzle lifetime. Development of the nozzle design which ensures high quality fuel atomization with minimal energy consumption is a relevant task. Tests with several variants of nozzles having different design were carried out in MADI. The first variant was distinguished by location of the injection holes entering edges in the nozzle sack. The second variant had the injection holes entering edges located on the locking cone of the nozzle body. The third variant had two groups of holes (on the locking cone and in the nozzle sack). The aim of the research was estimation of the influence of the location of the injection holes entering edges on parameters which determine the fuel injection process (penetration length and atomizing fineness). A possibility of fuel delivery correction by injection orifices and hence by combustion chamber areas taking into consideration diesel engine operation conditions was demonstrated. Applied research and experimental developments are carried out with financial support of the state represented by the Ministry of Education and Science of the Russian Federation under the Agreement No 14.580.21.0002 of 27.07.2015, the Unique Identifier PNIER: RFMEFI58015X0002.
