DEVICE FOR DETECTING INPUT SIGNALS OF A CONTROL UNIT IN AN INTERNAL COMBUSTION ENGINE

摘要

A device for detecting the rotation speed signals of a control unit which regulates the supply of fuel to an internal combustion engine involves the use of an (inductive) pulse generator jointly with a proven sensing technique. The moment of detection of the rotation speed signal may be freely controlled during a rotation of the crankshaft and/or the camshaft. This minimizes the time interval between the detection of the signal and the extraction of the output signals which vary with the rotation speed signal. Phase rotation in the regulating circuit is thus minimized and the dynamic behaviour is thereby considerably improved.
