ABSTRACT:
A method and apparatus for measuring or controlling the correct phase adjustment of periodic injection operations in cyclically operating internal combustion engines relative to a predetermined movement phase of the drive unit parts of the internal combustion engine, in which the closing of an injection valve of a working space is acoustically detected while the internal combustion engine rotates; the time interval of the beginning of the noise initiating the closing of the injection valve with respect to the predetermined movement phase of the drive unit parts belonging to the same working space is also determined whereby the thus determined time interval then serves at least indirectly as control value.
