Abstract
A method for starting an internal combustion engine that is operated with a fuel mixture made of at least two types of fuel. An injection of the fuel into combustion chambers of the internal combustion engine occurs starting at a predefined pressure threshold of the fuel in a fuel supply according to a high-pressure starting mode, and also according to a low-pressure starting mode if the predefined pressure threshold is no longer met. The pressure threshold is selected as a function of the mixture ratio of the fuel types in the fuel mixture. In this way it can be achieved that differences can be taken into consideration in the optimal mixture formation of the fuel types.
