The article presents the results of using a simulation method to study the spray penetration of liquid fuel injected from piezoelectric gasoline injectors used in modern high-pressure injection systems. The construction of the model and the course of the simulation study are discussed. The verification of the obtained results was carried out based on experimental tests conducted on a test bench equipped with a high-speed camera and digital image analysis. The verification procedure took into account the influence of ambient backpressure on the range and propagation speed of the spray.Simulation research methods concerning engine processes are an important tool determining the development of this field of technology. Their application allows for significantly shortening and optimizing the research process. (…)
