    Abstract: A variable geometry turbocharger (VGT) of an engine of a vehicle has a VGT mechanism and a VGT actuator connected to the VGT actuator. A controller is connected to the VGT actuator, and is configured to monitor at least one entry condition such as vehicle battery voltage, voltage at the VGT actuator, temperature of the engine, its oil, and its coolant, and exhaust gas temperature. If the entry conditions are met, the controller performs a learn procedure in which the VGT actuator cycles the VGT mechanism through its range of motion following a key-off shutdown command. The learn procedure may take place immediately preceding, during, or immediately following shutdown of the engine. The VGT actuator then reports to the controller an available range of motion of the VGT actuator and of the VGT mechanism.

  • Patent number: 10876468
    Abstract: A method for controlling a turbocharging system with a turbocharging stage for an internal combustion engine, wherein the turbocharging stage comprises a compressor and a turbine and the turbine is adjustable via a VTG control. The method includes: acquiring an operating state target variable; adjusting a maximum VTG control criterion to implement the torque increase by increasing a boost pressure, wherein adjusting the maximum VTG control criterion includes: determining a target boost pressure; determining a VTG target position as a function of the target boost pressure; determining an actual exhaust back pressure; determining a maximum exhaust back pressure; determining the VTG control criterion taking into account the difference between the actual exhaust back pressure and the maximum exhaust back pressure. The VTG control criterion limits the VTG target position such that an accelerated adaptation of an actual boost pressure to the target boost pressure) takes place.

  • Patent number: 10859012
    Abstract: A method for diagnosing a fault situation of a negative-pressure generation line using a fuel tank pressure sensor that detects the pressure of a fuel tank is provided. The method detects pressure in a fuel tank measured by a fuel tank pressure sensor when a turbocharger is operated for boosting and a purge valve is operated and diagnoses a current situation as a fault situation in which an engine negative-pressure generation line remains open when a pressure change value calculated based on the pressure difference of the fuel tank exceeds a reference value. A warning of a fault situation is then output when a fault is determined.

  • Patent number: 10851730
    Abstract: An anomaly determination device executes a first anomaly determination process and a second anomaly determination process. The anomaly determination device determines in the first anomaly determination process that an anomaly is present in a link mechanism when a fully-closed-time detection value is outside a closed-side normal range and when a fully-open-time detection value is outside an open-side normal range. The anomaly determination device determines in the second anomaly determination process that an anomaly is present in the link mechanism if the difference between the fully-closed-time detection value and the fully-open-time detection value is outside a normal distance range set in advance when it is not determined in the first anomaly determination process that an anomaly is present in the link mechanism.

  • Patent number: 10823031
    Abstract: An exhaust system includes a first exhaust after-treatment system receiving exhaust gases generated by an engine, a second exhaust after-treatment system downstream of the first exhaust after-treatment system, and at least one bypass connecting an engine outlet to an inlet to the second exhaust after-treatment system. A turbocharger is associated with the bypass and a bypass valve is located upstream of the turbocharger. The bypass valve is moveable between an open position to bypass exhaust gas flow to the first exhaust after-treatment system, a closed position to direct all exhaust gas flow to the first exhaust after-treatment system, and a partially open position where one portion of exhaust gas flow is directed into the first exhaust after-treatment system and a remaining portion of exhaust gas flow is directed into the turbocharger. A controller controls movement of the bypass valve between the open, closed, and partially open positions.
