Darst. The aim of this work is to show a model approach capable of describing the SI engines cold start. The model bases upon a zero-dimensional thermodynamic description of the various gas components. A description of the combustion of homogeneous as well as stratified charges by a fractal approach for the fully established turbulent flame proved to be successful. The cylinder pressure is transferred via a mechanical model of the power train into a driving torque. Quantifying loss torques as well as inertias in addition to this driving torque enables the simulation of the engine run-up. vorgelegt von Martin Reißig Rostock, Univ., Fak. für Maschinenbau und Schiffstechnik, Diss., 2012 ZL 5530 52.35 http://rosdok.uni-rostock.de/resolve?urn=urn:nbn:de:gbv:28-diss2012-0080-0 http://rosdok.uni-rostock.de/resolve?urn=urn:nbn:de:gbv:28-diss2012-0080-0&pdf http://nbn-resolving.de/urn:nbn:de:gbv:28-diss2012-0080-0 Modeling the cold start process of spark ignition engines--(DE-627)723718687 urn:nbn:de:gbv:28-diss2012-0080-0 oclc: 934851706 ppn: (DE-627)728583585
