Summary

Preliminary studies confirm the assumption that existing soot formation models have to be revised, or more detailed, phenomenological soot formation models must be established – especially in regard of the precalculation of the soot emission of combustion engines at extreme parameters (high pressure injection, high EGR, high pressure supercharging). In order to generate the necessary basic knowledge, the Chair of Combustion Engines (LVK) developed a novel gas sampling probe which permits the time-resolved gathering of small soot samples from the combustion chamber. Compared to common gas sampling probes, the new probe features several particularities [6], such as a novel injection process of a probe head into the inner flame core for the sampling...
