Introduction Natural ecosystems provide the material base of the human survival and development.
The human take benefits directly or indirectly from ecosystem services, including useful material and energy to the economic and social system, acception and conversion of wastes from the economic process and direct provision of services to human society [1].A healthy ecosystem is the basic guarantee of the realization of human social and economic development [2].

The relative importance of these different mechanisms is strongly affected by the temperature, pressure, flame conditions, residence time and concentrations of key reacting species.
But DWI technology could lead to slightly higher fuel consumption rate .When using the high sulphur fuel ,the material of the combustion chamber and using a special nozzle should be considered.
There are many kinds of structures and materials of filter used to catch the particulate, for example the monolithic ceramics, the metal wire, the textile fiber, the ceramic fiber, and floamed ceramics and so on.
