The IVK (Internal Combustion Engine Department) at the Vienna University of Technology proposed me to research into homogeneous charges compression ignition (HCCI). This research will be part of a project with a 2-stroke motor running with diesel HCCI combustion.
In recent years HCCI engines have been developed as an alternative combustion system to spark ignition (SI) and compression ignition (CI) engines. The major motivation for researching about HCCI, is that compared to the diesel engine, it has low NOx emissions and less problems with smoke. Diesel engines are widely used in automobiles, in heavy-duty vehicles and in other commercial applications, due to their high etticiency and durability.
However, the absence of a mechanism to trigger ignition has resulted in a major challenge to control combustion in HCCI engines. Other disadvantages include high carbon monoxide (CO) and hydrocarbon (HC) emissions, higher rate of pressure rise and limited operating range.
This thesis aims to gather many of the most important works on the topic homogeneous combustion and generallyabout new combustion strategies with an emphasis on obtaining both good etticiency and low NOx and PM emissions.
The first part is an introduction in the homogenous combustion process, in particular in the diesel HCCI process, with a description of its characteristics and peculiarity.
The main part of the text otters an overview of the most important combustion parameters, of the most significant ' homogeneous .combustion methods and the results they achieve. Then, it is followed by a description of how controlling and enlarging the operating range of HCCI; these are two of the goals which HCCI researchers try to achieve.
The final chapters describe the future applications, developments and goals.
