Homogeneous charge is a preferred operation mode of gasoline direct-injection (GDI)
engines. However, a limited amount of work exists in the literature for combustion models of …

This thesis discusses experimental investigations to reduce particle number emissions from
gasoline engines with direct injection. Measures on a single cylinder research engine with …

In recent years, the trend towards the performance maximization of modern internal
combustion engines has led to the creation of accurate simulation models to optimize the …

The prediction of local heat transfer and thermal stratification in the zero-dimensional
stochastic reactor model is compared to direct numerical simulation published by Schmitt et …

The focus of this paper is the fast determination of thermal boundary conditions in engine
combustion chambers. In contrast with many other studies, only cycle integrated quantities …

As the late combustion phase in SI engines is of high importance for a further reduction of
fuel consumption and especially emissions, the impacts of unburnt mass, located in a small …
