摘要

An internal combustion engine is operated according to a method, in which the fuel is pumped from a first fuel pump to a second fuel pump and from there into a high pressure region. The fuel passes therefrom into at least one combustion chamber of the internal combustion engine, by means of at least one fuel injection device. In certain operating conditions for the internal combustion engine, the pressure in the high-pressure region is reduced by means of a release device. According to the invention, the reliability and security on operating the internal combustion engine may be increased, whereby the functioning of the release device is monitored (58 to 68).
