摘要： PURPOSE:To provide an apparatus capable of measuring the dynamic injection timing of an engine without detaching various parts attached to the engine, by providing a detector attached to the outside of a part used in the injection system, a circuit for processing the output of said detector, a timing light, a Braun tube oscilloscope, etc. CONSTITUTION:A vibration detecting sensor 4 is attached to the portion of a lock nut used for fixing injection pipe 2 to injection nozzle holder 3. The output of this sensor 4 is afforded via amplifier 5 and band-pass filter 6 to oscilloscope 13 capable of measuring two phenomena, which represents waveform 1. After the waveform is shaped by detector 7 and comparator 8 added with reference voltage setter 11, the voltage is applied to trigger voltage generator 10 for energizing luminous discharge xenon tube 12. The voltage change across the two electrodes of this lumiuous tube 12 is represented as waveform 2 in oscilloscope 13. With such an arrangement, delay circuit 9 is controlled to conform the above two waveforms 1, 2 with each other for detecting the dynamic injection timing by reading crank angle indicating graduation 14 at the time when the two waveforms are conformed.

摘要： PURPOSE:To let the luminescence of a timing light coincide with signals given when a needle valve is opened by a method wherein there are provided a detector for high frequency oscillations generated by the shut and open by an injection nozzle needle valve, a detector for the rotation of an injection pump and a delayed- pulse-generator. CONSTITUTION:In a device for a Diesel engine, the output of a detector 1 of high frequencies generated by the operation of the injection nozzle needle valve (not illustrated) is amplified 3 and added to a band pass filter 4 to select valve opening signals, a detector 5, a comparator 6, a monostable multivibrator 7, a phase inverter 8 and a delayed pulse generator 9 which generates a delayed signal a given time after the valve opening signal is generated. On the other hand, the output of a detector 2 of the roration of the injection pump is added to an amplifier 10, a filter 11, a detector 12, a comparator 13, a monostable multivibrator 14, a delayed pulse generator 15 and time-width pulses of both detectors 1, 2 are generated in a pulse generator 16. These pulses are processed and given to a timing light 21 to make a timing display.
