Abstract
A method is provided for controlling an internal combustion engine operating in a homogenous mode. The internal combustion engine exhibits a control unit for setting the air supply, the fuel supply and the ignition angle. The method reduces the fuel consumption and increases a torque reserve that is to be made available for use. Starting from a specific distribution of air and fuel in the mixture, the air mass to be supplied is increased, which leans the air-fuel mixture such that a first torque reserve is generated. In the event of a positive torque request, the fuel mass to be supplied is increased in order to enrich the air-fuel mixture.
