Method for adjusting the pressure in a high-pressure system of a fuel injection system of an internal combustion engine and internal combustion engine for carrying out the method

摘要

Method for adjusting the pressure in a high-pressure system of a fuel injection system (7, 9) of an internal combustion engine (1), the high-pressure system comprising: - at least one high-pressure accumulator (17); - at least one fuel injector (1) which can be supplied with fuel by the high-pressure accumulator (17). ; characterized in that- a pressure reduction in the high-pressure system takes place in the context of a transition from a load operation to a load-reduced operation of the internal combustion engine (1) by means of injection of small injection quantities via the at least one fuel injector (21).
