Abstract
A method for fuel injection for starting an internal combustion engine, whereby upon closure of a starting contact, fuel injectors are operated simultaneously to deliver a first amount (ID,) of fuel to a number of cylinders (C,) and, after a synchronization signal (S,, S,) has been recognized, the injectors are operated sequentially. An angle of rotation (ANG) separating the angular position (START) of the engine upon closure of the starting contact from the angular position (SYNC) reached upon recognition of the synchronization signal is measured. This angle is compared with a predetermined value (THR), and when the angle of rotation is greater than the predetermined value, an additional amount (CMP) of fuel is injected into a cylinder (C,) determined on the basis of the cylinder (C,) in respect of which the synchronization signal was recognized.
