Diagnostic method and device for diagnosing an intake system of an internal combustion engine |
摘要 |
An internal combustion engine has an intake system (1) and an exhaust gas system (4). An exhaust turbocharger of the internal combustion engine has a compressor (42) arranged in the intake system (1) and a turbine (48) arranged in the exhaust gas system (4) of the internal combustion engine for driving the compressor (42). In order to diagnose the intake system (1), a charge pressure (PHS_AIC_DOWN) of the compressor (42) is determined in a predetermined operating state of the internal combustion engine. A leakage of the intake system (1) downstream of the compressor (42) is recognized if the determined charge pressure (PHS_AIC_DOWN) is lower than the predetermined base charge pressure (PUT_BAS) in the predetermined operating state.
