IC-Engines and Propulsion Systems I
The basic concepts of Internal Combustion (IC) engines, the working process and operating maps are introduced. With emphasis on the high pressure thermodynamic process and combustion-induced heat release, the thermodynamic processes are analyzed in detail and the design and modelling of combustion processes are discussed. The students are introduced to the gas exchange process (scavenging), heat-transfer mechanisms, and the concept of turbocharging. Further subjects explored are concepts of hybrid propulsion systems, energy storage on-board, decentralized cogeneration with IC-Engines, as well as waste heat recovery.
IC-Engines and Propulsion Systems II
Assuming a basic knowledge about internal combustion engines and the thermodynamic processes involved, the second part focuses on a detailed analysis of in-cylinder processes. The complex mechanisms behind in-cylinder mass transfer, dominated by turbulent flow fields and fuel spray, and being responsible for mixture formation are discussed. In a next step the chemical reactions leading to the heat release are highlighted, with focus on the ignition, premixed flame propagation and knocking. In addition, pollutant formation in internal combustion engines, such as NOx, particulate matter and unburned hydrocarbons, are discussed. Further subject are aftertreatment methods for all pollutant categories.
