Oil supply failure detection circuit

摘要

An internal combustion engine assembly including an internal combustion engine, an electronic control unit for generating control signals for controlling the engine and a solenoid oil pump for supplying oil to the engine. The oil pump includes an armature and a solenoid winding encircling the armature and being connected to the electronic control unit so that the electronic control unit causes movement of the armature and so as to allow the electronic control unit to detect the flow of current in the solenoid winding.
