Abstract
A method for adjusting the torque in an internal combustion engine is introduced having the steps: determining a desired torque; determining an operating point from measured values for air charge and rpm; determining a standard torque for this operating point; determining a desired efficiency from standard torque and desired torque; determining the lambda corresponding to this efficiency; determining the fuel quantity from the corresponding lambda and the air charge derived from measurement quantities. The fuel quantity in combination with the air charge yields the corresponding lambda for realizing the desired torque.
