Abstract
In known methods for carrying out a high-pressure start of an internal combustion engine, inconvenient starting behavior can sometimes occur. In a method for carrying out a high-pressure start of an internal combustion engine (), a high-pressure pump () is used to feed fuel from a fuel tank () to a pressure accumulator () and a pressure adjuster () is used to control the pressure in the pressure accumulator (), wherein the high-pressure pump () is operated before carrying out a fuel injection into a combustion chamber of the internal combustion engine (), and the pressure adjuster () is activated in such a way that, during the operation of the high-pressure pump (), the pressure build-up in the pressure accumulator () above a pressure limit value pTHRES, upon the exceedance of which the fuel injection is enabled, is delayed.
