Abstract: During a start, particularly during a cold start, of an internal combustion engine without additional auxiliary drive, a precisely metered fuel mass is introduced into a combustion chamber. In the case of an internal combustion engine having direct fuel injection, a rail pressure prevailing in a high-pressure accumulator is frequently only insufficiently built up during a start, which has an unfavorable effect on the mixture formation. To improve the start performance of the internal combustion engine, the injection pressure available in the high-pressure accumulator is monitored during the start, and fuel from the high-pressure accumulator is first injected into the at least one combustion chamber when the injection pressure has reached or exceeded a specifiable threshold value. This ensures that the rail pressure is high enough, in order to inject a sufficient quantity of fuel into the combustion chamber so that an ignitable air/fuel mixture is formed.

Abstract: In a direct start of an internal combustion engine, sufficient energy may need to be released in a first combustion to set the internal combustion engine into motion, if possible without the assistance of an additional assembly, such as an electromotive starter. For this reason, the carburetion of an air-fuel mixture, made up of the air mass present in a combustion chamber and the fuel mass injected therein, is of great importance. In order to improve the mixture formation during a start, e.g., during a warm start of an internal combustion engine, the fuel mass required for a mixture formation is introduced into the combustion chamber, in full or in part, already prior to a start phase by at least one injection, and the mixture formation may be improved in this manner by vaporization of the introduced fuel mass.
