The hydraulic valve auxiliary control unit (12) can be connected and cut off by means of an additional auxiliary oil circle (3) related to a main oil circle (2) of the internal combustion engine (1).
A correlative based technique, which estimates and calibrates the circle array antenna channel uncertainty used an auxiliary source, is given in this paper.
