Abstract (en)

[origin: WO2006045674A1] The invention relates to an exhaust gas turbocharger which comprises a compressor (20) and a turbine (18) having an adjusting drive (22) for adjusting a turbine geometry. A performance characteristic (P_KW) is determined depending on a turbine output (P_TUR), a mass flow (MF_TUR) through the turbine (18) and a gas temperature (T3) upstream of the turbine (18). A mass flow characteristic (MF_KW) is determined depending on the mass flow (MF_TUR) through the turbine (18) and the gas temperature (T3) upstream of the turbine (18) and a gas pressure (P4) downstream of the turbine (18). Depending on the performance characteristic (P_KW) and the mass flow characteristic (MF_KW), an adjuster position (PSN_VTG) of the adjusting drive (22) for adjusting the turbine geometry is determined using a characteristic diagram (KF_PSN_VTG). For control, an adjusting signal (SSG_VTG) for controlling the adjusting drive is determined depending on the adjuster position (PSN_VTG) for adjusting the turbine geometry. For diagnosis of the exhaust gas turbocharger, the exhaust gas turbocharger is diagnosed depending on the adjuster position (PSN_VTG).
