In order to provide an apparatus for the controlled production of nano-soot particles, a pore burner and a mixing device for the production of a pre-mixture of fuel and oxidizing agent are provided, wherein the mixing device is coupled to the pore burner so that the pre-mixture can be supplied to it.

Apparatus and method for the controlled production of nano-soot particles

A diagnostic system for a combustion chamber is provided which comprises a diagnostic element which can be inserted into a wall of the combustion chamber. A plurality of light guides penetrates the diagnostic element for detecting electromagnetic radiation occurring in the combustion chamber. A plurality of detection units is also provided, each detection unit being associated with a corresponding light guide. Each light guide guides the electromagnetic radiation from a spatial segment of the combustion chamber associated with that light guide. The spatial segments are different respective segments of the combustion chamber which are arranged so as not to overlap. Each detection unit detects the electromagnetic radiation from a corresponding light guide for combustion analysis.

In order to provide a measuring device for determining stoichiometric ratios when burning hydrocarbons by means of which stoichiometric ratios can be determined easily and reliably when burning hydrocarbons, it is proposed that a sensor be provided to detect an intensity of a first fluorescent radiation from C--H molecular fragments arising during the burning and a sensor be provided to detect an intensity of a second fluorescent radiation from molecular fragments arising during the burning and comprising only C atoms, that the sensors generate an intensity-dependent first and second sensor signal, respectively, on the basis of the first and the second fluorescent radiation, and that an evaluation circuit be provided which generates an output signal corresponding to a stoichiometric ratio from a ratio between the intensities of the first and the second fluorescent radiation.
