Patent ID: 7805237

Claim:
A method for operating an internal combustion engine with a combustion method of homogeneous auto ignition that converts a driver's demand, predetermined by way of a gas pedal into a desired torque to be given off by the internal combustion engine, comprising the following steps: determining a reference charge value for air charging by way of a predetermined working-point-dependent lambda value (λ opt ); setting a throttle valve position based on said reference charge value; calculating the desired torque with the reference lambda value, parallel with said step of setting; and calculating an actual charge value measured from a charge detection to yield a fuel amount to be injected; wherein the reference lambda value is based on a determined optimal lambda value for a mode of operation of homogeneous compression ignition, as long as said optimal lambda value is within rich and lean limits, respectively, of a combustion method of homogeneous compression ignition, and wherein the fuel amount is adjusted at the rich limit and lean limit, respectively, of the combustion method, by lambda regulation, so that the amount of fuel to be adjusted allows dynamic operation within the operating mode of homogeneous compression ignition.
