Abstract

In a method of starting an internal combustion engine having a plurality of piston-cylinder units wherein there are dead volumes upstream of the piston-cylinder units, wherein upon an attempt at starting the internal combustion engine, the pistons are driven in the cylinders by an auxiliary motor. The maximum permissible duration of a starting attempt is restricted by a predetermined starting time (ts) of the internal combustion engine. The starting time (ts) is calculated and predetermined prior to or at the beginning of a starting attempt of the internal combustion engine depending on a state of the internal combustion engine and/or the auxiliary motor.
