Abstract
A present invention relates to fuel pump operating condition detectors, and more particularly to a fuel injection pump operating condition detector suitable for use in a distributor type fuel injection pump in a diesel engine mounted in a motor car, wherein fuel is pressure fed by a reciprocating plunger. The detector comprises an unpenetrated mount formed in a pump housing of the fuel injection pump adjacent the plunger or a reciprocating part operatively associated with the plunger and an electromagnetic pickup, the forward end of a core of which is fixed to the mount, and said electromagnetic pickup can detect through its output waveshape the running condition of the engine or the top and bottom dead centers of the plunger of the pump, which are the characteristics equal to a fuel injection timing, and a fuel pressure feed timing.
