  • Patent number: 8104452
    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 (1), a high-pressure pump (22) is used to feed fuel from a fuel tank (17) to a pressure accumulator (20) and a pressure adjuster (23) is used to control the pressure in the pressure accumulator (20), wherein the high-pressure pump (22) is operated before carrying out a fuel injection into a combustion chamber of the internal combustion engine (1), and the pressure adjuster (23) is activated in such a way that, during the operation of the high-pressure pump (22), the pressure build-up in the pressure accumulator (20) above a pressure limit value pTHRES, upon the exceedance of which the fuel injection is enabled, is delayed.
