Abstract
A method is provided for equalizing the cylinders of a multi-cylinder internal combustion engine. The internal combustion engine is configured as a reciprocating engine having direct injection and spark ignition. A fuel mass is injected in a cylinder-specific manner, and a cylinder-specific air mass and a cylinder-specific ignition time are each adjustable. An injection amount is equalized, then a charge is equalized and then a mean combustion pressure is equalized.
