BED FOR STUDYING DYNAMICS OF INTERNAL COMBUSTION ENGINE

摘要

SUMMARY OF THE INVENTION: increase information allows the investigation of the stand diesels due to permit it to determine the frequency response. After starting the diesel excitation coil fed by electro-autotransformer, transformer, rectifier, smoothing filter voltage DC, and an excitation coil fed by a generator from a magnetic amplifier sinusoidal voltage of different frequency but the same amplitude. The shaft is of electro-moment value is proportional to the amount of voltage applied to the excitation winding, on the outputs of the torque sensor and transducer movement of the fuel pump rack are signals from D.C. and sine component. Sinusoidal components of these signals are isolated elements and transducers are converted into amplitude values ​​of the voltage the DC level of which is substantially equal to the amplitude supplied to the voltage converter. The received signals are supplied to a divider whose output pern- striruets device. By varying the oscillator output signal frequency by a device registering signals from m values ​​which is constructed of the amplitude-frequency response of the diesel. 6 yl. FROM
