Abstract

The paper presents an attempt to apply a simulation method in the investigations into liquid fuel atomization generated from piezoelectric gasoline injectors used in modern high-pressure injection systems. Individual stages of the simulation research have been discussed and an experimental verification of the method has been carried out. The results of the simulation and experimental research of the injection of liquid fuel have been presented in the form of influence of air backpressure on the fuel spray atomization and fuel propagation.
