decisions and, therefore, determines that the criterion meets significant differences.

The drawing shows a structural diagram of a device for measuring energy loss, which contains an optical radiation detector 2, a voltage sensor 3, a current sensor 4, an optical energy meter unit 5, a synchronization unit b, an electric energy meter unit 7, a signal splitter 8, an analog- digital converter 9 and information block 10. The output of the optical radiation receiver 2 is connected to the input of the optical energy meter 5, the output of which is connected to the first input of the signal splitter, the output of the current sensor 4 is connected to the input synchronization unit and the first input of the electric energy meter 7, the second input of the electric energy meter is connected to the output of the voltage sensor 3, the output of the electric energy meter 7 is connected to the second input of the signal splitter 8, the output of the signal splitter 8 is connected to the input of the analog-to-digital converter - developer 9, the output of the analog-to-digital converter unit 9 is connected to the input of the information unit 10, the first output of the synchronization unit 6 is connected to the control input of the optical energy meter 5, the second output is and synchronization b is connected to the control input of the electric energy meter 7, the third output of the synchronization block G is connected to the control input of the analog-to-digital converter 9.

The device operates as follows. When the spark plug is operating, the optical radiation receiver 2 receives the radiation flux from the studied spark gap of the candle 1, and, as is known, the radiation flux and, therefore, the photocurrent are proportional to the instantaneous power of the spark. The photocurrent pulses arrive at the input of the block of the optical energy meter

5. where they are amplified and integrated, and time-integrated pulses are taken out, the magnitude of which is proportional to the usable energy of the microcircuit discharge. Simultaneously with the current sensor and voltage sensor, the pulses are fed to the input of an electric energy meter, where they multiply and are integrated, and pulses are taken out of the output with a value equal to the energy of the spark discharge, taking into account losses in the spark discharge, Pulses from the outputs of the optical energy meter and electric energy meter arrive at the input of the signal splitter, at the output of which pulses equal to the ratio of the input signals appear. The signals from the output of the signal splitter are fed to the input of an analog-to-digital converter, where the analog signal is converted to digital. Simultaneously with the arrival of the signal to the inputs of the energy meters, the pulse of the current sensor is fed to the input of the synchronization unit, the pulses of which are pulled out to control the integrators in the energy meters and to start the analog-to-digital converter. From the output of the analog-to-digital converter, the signal does not enter the display unit input, where the measurement results are read. At the end of the counting and indication of the results of measuring the energy loss of the spark, the device is ready to receive information about the next discharge pulse in the spark plug. The measurement cycle is repeated.

Thus, in comparison with the prototype, the proposed technical solution allows to measure the amount of useful released energy and the amount of loss on the candle, and the device also makes it possible to quickly control the amount of energy loss.
