The research project AZ-1004-11 "TWIN-JET" comprised the two main objectives of a potential analysis of the atomization principle with novel double jet spray injectors on the one hand and the verification of pulsation dampers made of porous materials for modern common rail injection systems on the other hand. The project partners consisted of the two university institutes Chair of Process Machines and Plant Engineering (iPAT) and Chair of Technical Thermodynamics (LTT) of the Friedrich-Alexander-University Erlangen-Nuremberg. The industrial partners Bayerische Motoren Werke AG (BMW), Robert Bosch GmbH (Bosch), FMP Technology GmbH (FMP) and Geiger Fertigungstechnologie GmbH (Geiger) were also involved.
The task of the LTT was to investigate the spray properties of twin-jet sprays using optical measurement techniques in comparison to conventional free jet sprays. Investigations were carried out for a large number of different operating conditions that occur in gasoline direct injection. Furthermore, the group was responsible for the adaptation of the novel injectors to the transparent engine and the optical investigation of the mixture formation in the engine.
