| 内容： | The invention relates to a method for production of a heating body (26; 88, 90) made from a ceramic composite material (64, 66, 72) for an engine component (12) of a self-ignition internal combustion engine. The following method steps are carried out in production of the heating body (26; 88, 90): a measuring channel (58) is generated during the forming process for the heating body (26; 88, 90), a porous, however, chemically identical material (66, 72) is introduced into the generated measuring channel (58), the heating body (26; 88, 90) with the introduced insulation material (72) is subjected to a thermal treatment, an integrated particle filter (74) is generated at the combustion chamber end (52, 54) of the heating body (26; 88, 90) the porosity of which is in the range of 1 vol. % and 90 vol. % and the mean pore diameter of which is in the range of 0.1 to 1000 ?m. |
