Abstract

Methods and systems are provided for optimizing the operation of a multi-cylinder auto-ignition internal combustion engine. In one example, cylinders of the auto-ignition internal combustion engine may form two groups of cylinders, where one group of cylinders has a larger compression ratio, smaller width, and smaller volume than the other group of cylinders, and where at least one cylinder of the other group is configured as a switchable cylinder that is deactivated in a load-dependent manner. By configuring the cylinders in multiple groups based on compression ratios, and operating the cylinders in a load-dependent manner, fuel consumption may be optimized.
