Combustion can be viewed as a process of “heat release”; the liberation of chemical energy in the fuel. Propulsion systems such as jet or car engines all rely on burning a fuel to produce power. Despite its wide application the combustion process is far from being fully understood, and it continues to be a very major field of research.
In automotive internal combustion engines for instance, it significantly influences the performance and fuel economy of the engine and the emission of pollutants.
Characteristics of the fuel, chemical kinetics, air/fuel mixture preparation and the phasing of combustion within the engine cycle, all affects the shape of heat release and the formation of pollutants, such as oxides of nitrogen (NOx) and particulate matter also known as soot. There is much going on to develop more efficient and low polluting designs and, with state-of-the-art facilities and allied technical and academic expertise, the group offers a diverse range of research and commercial capabilities in the area of combustion engineering.
