A method for operating a drive system for a motor vehicle having an internal combustion engine and having an electric motor. The internal combustion engine can be operated in a partial operating state as well as in a full operating state. A first threshold is defined for a target drive torque to be applied by the drive system for a switchover from the partial to the full operating state. After the first threshold is exceeded, a switchover is delayed for a defined period of time. A difference between the target drive torque and the actual drive torque of the internal combustion engine is compensated for by the electric motor. After the period of time has elapsed, a switchover from the partial operating state into the full operating state takes place if the first threshold value continues to be exceeded or a compensating operation of the electric motor is ended.

A cylinder of a combustion engine for a vehicle includes at least one intake duct and a spark plug which in turn includes a ground electrode. The spark plug is mounted in the cylinder such that during an operation of the combustion engine the ground electrode is cooled in as optimum a manner as possible by an airflow generated by the at least one intake duct. A spark plug and a method for manufacturing a cylinder of a combustion engine are also provided.

When fuel is injected into a combustion chamber () of a cylinder () of an engine () of a vehicle (), the fuel is injected in the form of multiple jets () with the aid of an injector (). In this connection, a first plane is defined in which both the central axis () of the injector () and the central axis () of the cylinder () lie. Furthermore, a second plane is defined in which both the central axis () of the injector () and the surface normal of the first plane lie. The jets () are generated in such a way that for each jet pair, which is formed from two of the jets (), an angle between the projections of the two central axes of the two jets of the jet pair into the second plane is smaller than 50&#xb0;.
