projects: <QuerySet [<Project: Active pre-chamber ignition systems for novel car combustion processes (LEANition), LEANition, , , <p>In the LEANition project, the possibilities and limits of a purged prechamber ignition in passenger car gasoline engines are to be demonstrated. The pre-chamber is a small ignition chamber around the spark plug, which is connected to the combustion chamber by transfer ducts and is actively supplied with a fuel-air mixture in addition to the charge exchange with the main combustion chamber. The application is based on the innovation of extracting the mixture required to supply the pre-chamber from the conventional petrol tank above the liquid level. The gas atmosphere there is very rich in fuel. The prechamber ignition shows the potential for significantly reduced fuel consumption in the partial load range while simultaneously reducing NOx emissions through the use of homogeneous lean mixtures (λ ≈ 2) or high to very high residual gas contents (EGR ≥ 30 %). The high ignition energy of the pre-chamber ensures the ignition of these mixtures which are unwilling to ignite. Active prechamber ignition is known for large gas engines, but cannot yet be implemented in passenger cars. The use of the fuel already available (in gaseous form) makes it possible to convert prechamber ignitions into car drives.<br />In the project the partners are striving to generate a deep understanding of the interactions of the prechamber ignition and thus to lay the foundation for the development of a combustion process that can implement the above-mentioned advantages in passenger car propulsion. This can be based on the results of the preliminary study carried out by the project partners, which proved that the enrichment of the pre-chamber through the use of the gas phase in the tank is possible.<br /></p>, , 2019-08-01, 2022-07-31, , 2022-07-31, Third party funded individual grant, True>, <Project: Reduction of particulate emissions from direct-injection gasoline engines (PN Reduktion), PN Reduktion, , , , , 2017-08-01, 2020-07-31, 2021-01-31, 2021-01-31, Third party funded individual grant, True>, <Project: TwinJet -- a new colliding jet atomization concept (TwinJet), TwinJet, , , <p>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.<br />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.<br /></p>, , 2012-06-01, 2014-11-30, , 2014-11-30, Third party funded individual grant, True>]>
