Abstract
With a method for converting a fuel quantity (MF) into a torque (TQ) in an internal combustion engine, the efficiency (H) of the internal combustion engine is determined at the current operating point prior to the conversion as the ratio of actual torque (TQ) and actual fuel quantity (MF), and the required torque (MF) is determined from the efficiency (H) and the fuel quantity (MF).
Claims15
A method for converting a nominal fuel quantity into a nominal torque for an internal combustion engine, comprising the steps of:
- prior to the conversion at the current operating point, determining the efficiency of the internal combustion engine as a ratio of actual torque and actual fuel quantity, and
- determining the nominal torque from the efficiency and the nominal fuel quantity.
A method for converting a nominal fuel quantity into a nominal torque for an internal combustion engine, comprising the steps of:
- prior to the conversion at the current operating point, determining the efficiency of the internal combustion engine as a ratio of actual torque and actual fuel quantity by using an efficiency curve which indicates the maximum ratio of torque and fuel quantity as a function of the fuel quantity, and
- determining the nominal torque from the efficiency and the nominal fuel quantity.
