Method for operating an internal combustion engine, and internal combustion engine with controlling device for carrying out the method

摘要

Oil may be pumped into one or other of the working chambers to change the phase angle of the camshaft with respect to the camshaft timing gear. The first operating step (101) uses a monitoring device which determines whether the camshaft is at a given phase angle to a calibration mark. If the answer is NO (n), the step is repeated; if YES, (j), the second step (102) is performed to raise the tickover value of the engine to an intermediate value, at which the oil pressure is high enough to adjust the camshaft phase. The third step (103) determines whether a criterion for ceasing the adjustment has been met. If NO, the step is repeated, if YES, then the fourth step (104) is performed, reducing the tickover speed to its usual value.
