In a method for the individual shutdown and restart of cylinders of a multi-cylinder internal combustion engine having at least one intake and one exhaust valve per cylinder, a variable valve control, and a fuel injection system, according to the requirement of its shutdown, a deactivateable cylinder is filled with fresh gas and according to the requirement of its restart, an injection of a predetermined quantity of fuel as well as an ignition of the mixture takes place in the chronologically next intake phase or compression phase of the cylinder before the end of the compression phase at the latest. Furthermore, for the individual shutdown and restart of cylinders, the mass of fresh air present in the deactivateable cylinder in the deactivated operating state and/or the mixture parameters are determined and consulted for determining a fuel quantity to be injected when restarting said cylinder.
