A method of synchronization or a cylinder coordination to a crankshaft position in a multi-cylinder internal combustion engine with a crankshaft which rotates twice per working cycle, comprising the steps of supplying an output signal with a crankshaft transmitter, which per revolution of the crankshaft supplies a reference signal associated with an upper dead point of a cylinder, evaluating the output signal of the crankshaft transmitter by a control device for determining a rotary speed of the crankshaft and for forming injection signals, performing a preliminary synchronization after a detection of the reference signal and releasing a probe injection for an associated cylinder, verifying the preliminary synchronization in the case of a rotary speed increase or a rotary speed acceleration, in the event of a failing rotary speed increase, performing a new preliminary synchronization which is offset by a predetermined angle to release an injection for a cylinder presumably in an upper dead point, and verifying this preliminary synchronization during a rotary speed increase.
