PROCESS FOR MONITORING OF AT LEAST ONE TURBOCHARGER
The invention relates to a method for monitoring at least one exhaust gas turbocharger (ATL) of a large internal combustion engine (BKM), comprising at least one compressor (1a) and one exhaust gas turbine (1b) arranged on the same shaft as the compressor, wherein the current pressures (p1, p2) upst...

| description | The invention relates to a method for monitoring at least one exhaust gas turbocharger (ATL) of a large internal combustion engine (BKM), comprising at least one compressor (1a) and one exhaust gas turbine (1b) arranged on the same shaft as the compressor, wherein the current pressures (p1, p2) upstream and downstream of the compressor (1a) and the current temperatures (T1, T4) upstream of the compressor (1a) and upstream of the exhaust gas turbine (1b) are measured. In order to monitor an exhaust gas turbocharger effectively and as simply as possible, the current pressures (p4, p5) upstream and downstream of the exhaust gas turbine (1b), the current temperatures (T2, T5) downstream of the compressor (1a) and downstream of the exhaust gas turbine (1b), and the rotational speed (nA) of the exhaust gas turbine (1b) are measured, preferably continuously, the efficiencies (ην) of the compressor (1a) and of the exhaust gas turbine (1b) are calculated from the measured data, and a diagnostic algorithm is started when a worsening of the efficiency (ηTV, ηT) of the compressor (1a) and/or of the exhaust gas turbine (1b) is detected or after a defined time interval has elapsed. |
