The paper describes a simulated injection of PB 95 and E85 to an intake pipe. Integrated with a model of an injector, a geometric model of an intake pipe of a diameter that corresponds to real dimensions was developed with AVL FIRE software. Twenty consecutive injections of these types of fuel to the intake pipe were simulated. The studies focused on how the intensity of fuel film formation was impacted by PB 95 and E85 depending on engine speed and the pressure in the intake pipe. The paper provides selected results for several engine operating points.
