Abstract: In a method for operating an internal combustion engine that has a starter device for starting the internal combustion engine and a device for supplying fuel controlled by a control device, it is determined whether cold start conditions or hot start conditions exist during starting of the internal combustion engine. In at least one operating range, during starting of the internal combustion engine, an engine speed gradient is determined during a slowdown phase of a pull stroke of a starter device and the engine speed gradient is used for determining whether cold start conditions or hot start conditions exist. The fuel quantity to be supplied to the internal combustion engine is controlled based on the determined cold start conditions or hot start conditions.

Abstract: In a method for controlling a hydraulic power wrench with a pivotable lever pivoted by a piston-cylinder unit and a ratchet arrangement for stepwise rotation of a ratchet bushing by advancing and return strokes, parameters such as nominal torque or pre-load or screw parameters are entered into an electronic input unit. Nominal pressure corresponding to the parameters is determined by an electronic evaluation unit and generated by the pump. The piston-cylinder unit is pressure-loaded for performing a pre-stroke until the nominal pressure is reached followed immediately by a return stroke. A time interval from beginning of pressure loading until reaching nominal pressure or until reaching an initial pressure after pressure relief is measured. Pressure loading and measuring are repeated. The measured time intervals are compared. Pressure loading cycles are stopped when at least the last measured time interval is shorter than at least the penultimate measured time interval.
