heal.abstract	The main scope of this work is to examine the combustion mechanism in Direct Injection (DI) diesel engines. For this purpose heat release rate calculations were conducted on a variety of DI diesel engines ranging from large low-speed marine engines to medium-speed marine and stationary engines to high-speed DI diesel engines. The Top Dead Center (TDC) is determined by a thermodynamic method developed offering an accuracy of 0.1 CA. The heat loss rate to the cylinder walls used to calculate the gross heat release rates is determined using a simulation model and a newly developed method to estimate the heat transfer model constants. The results reveal a strong dependence of the heat release rate and thus the combustion mechanism on engine design. A great difference of the combustion mechanism is observed between low-speed marine and high-speed diesel engines. This has implications for the design of the fuel injection system and for the proper tuning of these engines.	en
