Abstract

A pressure oil supply arrangement for a hydraulically actuated timing device cooperating with an injection pump for the control of the injection start in multi-cylinder, air-compressing injection internal combustion engines, with an electromagnetic control unit for the control of the pressure oil inlet or return in a feed line in communication with the timing device; the electromagnetic control unit is thereby controllable by an electronic control apparatus in dependence on operating parameters of the internal combustion engine and the connection to the timing device is adapted to be interrupted by the control unit during each injection operation.
