    摘要: A method controls an internal combustion engine in a drive train having a hydraulic torque converter with a pump wheel and a turbine wheel, during a changeover from an overrun mode into a traction mode. In the method, the rotational speeds of the pump wheel and of the turbine wheel are sensed simultaneously and compared with one another, and a deviation of the rotational speed of the pump wheel from the rotational speed of the turbine wheel being determined. If the rotational speed of the turbine wheel is higher than the rotational speed of the pump wheel and the deviation drops below a predefined threshold value, the torque of the internal combustion engine is set in dependence on the deviation and a rate of change of the rotational speed of the pump wheel. Furthermore a control unit is configured to carry out such a method.

    摘要: A method for operating a turbocharged internal combustion engine having an after-treatment device for treating exhaust gas discharged from the turbocharger, wherein exhaust gas from the engine is passed through a variable-geometry mechanism for regulating power produced by the turbine. The method comprises the steps of measuring a boost pressure of the air delivered to the intake of the engine, measuring a temperature of the exhaust gas delivered to the after-treatment device, causing the temperature of the exhaust gas delivered to the after-treatment device to substantially match a predetermined target temperature by controlling the variable-geometry mechanism of the turbine to control the amount of power extracted by the turbine, and causing the boost pressure to substantially match a predetermined target boost pressure by either inputting mechanical power into or extracting mechanical power from the turbocharger, as required, using a power addition/extraction device, such as a motor/generator, coupled to the turbocharger.
