摘要： PURPOSE: To aim at reduction in exhaust pollution and the promotion of efficiency in maintenance work, by installing a time measuring circuit, which measures the time required in time of light emission of a xenon flashing apparatus, and also a revolving speed measuring circuit which measures rotational frequency in a crankshaft.
CONSTITUTION: A xenon flashing apparatus A1 has a delay regulator A3, while a xenon flashing apparatus B2 has a delay regulator B4 and they are connected to a detector 5 in common. In time of light emission of these xenon flashing apparatuses 1 and 2, a time difference between their signals are measured by a time measuring circuit 7. A revolving speed measuring circuit 8 measures rotational frequency of a crankshaft, while an operational circuit 9 calculates the measured time difference and the rotational frequency, converting this operated value into a crankshaft turning angle, whereby it is displayed on a displayer 10 together with the rotational frequency. Thus, reduction in exhaust pollution and efficiency in maintenance work are well promoted.

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.
