Abstract: Apparatuses, methods, and systems for starting an internal combustion engine under cold start conditions are disclosed. A combustible mixture is supplied to a plurality of cylinders of the internal combustion engine, where a number of ignition devices are operably connected with less than all of the plurality of cylinders so that at least one of the plurality of cylinders does not include an ignition device. In one form, only one ignition device is included in a bank of cylinders. In response to a cold start condition, a spark by the plurality of ignition devices is generated to cause ignition of the combustible mixture and start the internal combustion engine. In response to a normal or non-cold starting condition, the internal combustion engine is started by compression ignition where none of the ignition devices generate a spark.
