Abstract

A method for operating an internal combustion engine in which a speed-based feature of the internal combustion engine, which is correlated with an indicated mean effective pressure of the fuel, is determined during the warm-up of the internal combustion engine and an ideal fuel quantity, which is to be injected into at least one combustion chamber of the internal combustion engine during the warm-up, is ascertained therefrom.
