Abstract
A method of detecting the timing of fuel injection in a diesel engine for the regulation of the timing of fuel injection by a fuel injection timing regulator is disclosed. Rotation angle indicating lugs are provided on the crankshaft of the engine connected to the input shaft of the fuel injection timing regulator and on the output shaft of the fuel injection timing regulator to measure the time difference between pulses corresponding to the lugs on the input and output shafts making relative rotation, and a reference rotation angle indicating lug is provided adjacent to each of the lugs provided on one of the input and output shafts to measure the reference timing difference between pulses corresponding to the lugs on the shaft under rotation. The phase angle of the output shaft relative to the input shaft can be accurately calculated on the basis of the former and latter time differences.
