An apparatus is described for measuring fuel injection advance angle of a diesel engine. The apparatus consists of: a first pulse generator for generating first detection pulses in response to the lift movement of a needle valve of a fuel injection valve; a second pulse generator for generating second detection pulses each time the crankshaft of the engine reaches a predetermined reference angular position; a signal generating means responsive to the first and the second detection pulses for producing an electric signal showing a desired angle range of the crankshaft; a masking means for masking undesired signal components produced from the first pulse generator in accordance with the electric signal; and means for detecting an injection advance angle value in accordance with the first detection pulses obtained through the masking means and the second detection pulses; wherein the signal generating means includes a computing section for computing the desired angle range of the crankshaft on the basis of the generating period of the second detection pulses.
