METHOD AND LEAKAGE DETECTION UNIT OF AN INTERNAL COMBUSTION ENGINE FOR LOCALIZING LEAKAGE OF AT LEAST ONE GASEOUS MEDIUM AT THE ENGINE

METHOD AND LEAKAGE DETECTION UNIT OF AN INTERNAL COMBUSTION ENGINE FOR LOCALIZING LEAKAGE OF AT LEAST ONE GASEOUS MEDIUM AT THE ENGINE

The present invention relates to a method for localizing leakage of at least one gaseous medium at an internal combustion engine (10), comprising a step of emitting at least one electromagnetic radiation beam (two shown 26a,26b, with different wavelengths) through at least one analysis section (28)...

Zusammenfassung:The present invention relates to a method for localizing leakage of at least one gaseous medium at an internal combustion engine (10), comprising a step of emitting at least one electromagnetic radiation beam (two shown 26a,26b, with different wavelengths) through at least one analysis section (28) disposed at or in the vicinity of an outer surface of the engine (10); a step of measuring a radiation characteristic of the radiation beam (26) after passing through the analysis section (28); and a step of determining a leakage of the gaseous medium into the analysis section (28) in dependence on the measured radiation characteristic.
