Abstract: A flow rate adjustment method for a variable geometry turbocharger may include steps as follows. An adjustment apparatus drives an actuator to an abutment position where a power transmission member abuts a stopper. The apparatus acquires the abutment position opening amount based on an opening detection sensor's signal. The apparatus drives the actuator until the detection amount attains a pre-set amount, moving the power transmission member to a temporary control position. The apparatus acquires a temporary control position flow rate. It is acquired when an adjustment gas inflow apparatus causes the adjustment gas to flow into an exhaust turbine, and a flow rate measurement sensor measures the flow rate of the adjustment gas. The apparatus obtains a correction amount based on a difference between the temporary control position flow rate and a real control position flow rate, which is a proper flow rate corresponding to the pre-set amount.
