Abstract
A method for injecting fuel into an internal-combustion engine. In a method for operating an injection system, injection into the individual cylinders is carried out by groups before a synchronization time at which the position of the individual signals is known on the basis of two transmitters. The groups are selected such that an injection into an open intake valve is avoided. Upon transition to the normal, sequential injection, the first cylinder into which injection is carried out is identified such that no double injection at a cylinder occurs. This method avoids a lengthening of the start time due to the lack of injection and also avoids an increased exhaust emission due to bank injection before the synchronization time.
