Abstract:
A method for controlling an internal combustion engine by means of interventions in at least one manipulated variable of the internal combustion engine said method comprising the steps of: determining a setpoint torque or work which is to be provided at the crankshaft of the internal combustion engine, determining, with respect to a first variable representing work which is to be performed or a setpoint torque to be provided, a corresponding setpoint quantity of heat taking into account the instantaneous actual efficiency setting at least one associated manipulated variable in accordance with the value of the setpoint quantity of heat,sensing the actual quantity of heat is also determined, and determining a setpoint efficiency from the actual quantity of heat taking into account the work which is to be performed or the setpoint torque which is to be provided, and setting at least one manipulated variable of the internal combustion engine approximately simultaneously in accordance with a setting of the determined setpoint efficiency for controlling the engine.
