Abstract (en)
[origin: WO2012007307A1] The invention relates to a method and to a control unit (24) for controlling a single-cylinder or multiple-cylinder internal combustion engine (10) having at least one fuel injector (14) per cylinder (12), at least one camshaft (20) for actuating inlet valves (16) and/or outlet valves (18), and having a control unit (24) which controls the fuel injectors (14) in such a way that they inject in each case one fuel pre-injection per cylinder (12) during a starting phase of the internal combustion engine (10). In order to make an improved pre-injection strategy possible during the starting phase, according to the invention at least one cylinder pressure signal (P) which is supplied by a cylinder pressure sensor (32) for measuring the pressure in a cylinder (12) is evaluated with regard to interference signals (S1), and the evaluation result is taken into consideration at least during the starting phase in a determination of the camshaft angle.
