Claim Text:
1. A method for controlling a single- or multi-cylinder internal combustion engine having at least one fuel injector per cylinder for injecting fuel, at least one camshaft for actuating inlet valves and/or outlet valves, which camshaft rotates at half the speed of a crankshaft, a crankshaft sensor that supplies a crankshaft signal having a synchronization pulse for each crankshaft revolution, said signal representing the crankshaft angle, and a control unit configured to control the fuel injectors during a starting phase and during a normal operating phase, the method comprising: the control unit receiving at least one cylinder pressure signal from a cylinder pressure sensor for measuring the pressure in an associated cylinder having multiple associated valves, the control unit determining interference signals from the at least one cylinder pressure signal with regard to interference signals, the control unit evaluating the interference signals by: the control unit determining the camshaft angle based at least on an evaluation result of the evaluation, and the control unit controlling the fuel injectors during the starting phase based on the determined camshaft angle.
