Abstract (en)
[origin: WO0026522A1] The invention relates to a method for adjusting the engine torque of an internal combustion engine. Said method comprises the following steps: determining a desired engine torque, determining an operating point from the measured values for air supply and rotational speed, determining a standard torque for said operating point, determining a desired efficiency calculated from the standard torque and the desired torque, determining the lambda value pertaining to said efficiency, determining the amount of fuel from the pertaining lambda value and the air supply derived from the measured values, which together with the air supply gives the pertaining lambda required for achieving the desired torque.
