Description
(54) УСГЮЙСГВО ДЛЯ ИЗМЕРЕНИЯ СРЕДНЕГО ИНДИКАТ №НОГО ДАВЛЕНИЯ В ЦИЛИНДРЕ ПОРШНЕВОГО ДВИГАТЕЛЯ(54) USGUSGVO FOR MEASUREMENT OF MIDDLE INDICAT NO. OF PRESSURE IN CYLINDER OF PISTON ENGINE
проход ишй через них, попадает только на фотодаод13 .the passage through them falls only on the photodiode13.
Перед измерением диск 9 ориентируют относительно исследуемого цилиндра 1 и закрепл ют на валу. Во врем работы двигател световой поток от лампы 14 проходит сквозь прорези 10 в такте сжати и прорези 12 в такте расширени .Before measurement, the disk 9 is oriented relative to the cylinder 1 under study and fixed to the shaft. During engine operation, the luminous flux from the lamp 14 passes through the slits 10 in the compression stroke and the slits 12 in the expansion stroke.
В результате фотодиод 11 вьфабатывает импульсы тока, управл ющие работой зтктронного коммутатора 4 только во врем такта сжати , Фотодиод 13 вьфа&тывает аналоппные импульсы, относ щиес к такту расивфешш и у1фавл ющие работой электрошюго коммутатсфа S.As a result, the photodiode 11 absorbs the current pulses that control the operation of the on-chip switch 4 only during the compression stroke, the Photodiode 13 is analogous to the analog oscillatory pulses, which are related to the timing pulse and the operation of the electrosurgical switch S.
Если выключатель 15 включен, а выклкпа тель, 16 выключен, то электроиньш KpMMytaxq) 4 будет пропускать сигнал давлени га иит«грирук щий п{Я1бор7 в тот момент, когда фотодиод 11 освещен, т.е. в соответствии с коэффициентом ослаб;|ени только во врем такта сжати , а так как выключатель 16 выключен, управл ющий а-иал на электронный коммутатор 5 поступать не будет и ннтепжрующий прибор 7 псосажет среднеинтегральное давление сжати .If the switch 15 is turned on and the switch off, 16 is turned off, then the electric power supply KpMMytaxq) 4 will pass the pressure signal ga "gripping n {i1bor7" at the moment when the photodiode 11 is illuminated, i.e. in accordance with the weakening factor; | s only during the compression stroke, and since the switch 16 is off, the control a-al will not be sent to the electronic switch 5 and the tightening device 7 will average the integral pressure of compression.
Если выключатель 15 выключен, а включатель 16 включен, то управл ющий сигнал будет поступать только от фотодиода 13 на электронный коммутатор 5, и соответствешю интегрирующий прибор 7 будет показывать среднеинтегральное давление расщирени .If the switch 15 is turned off, and the switch 16 is turned on, then the control signal will only come from photodiode 13 to the electronic switch 5, and the corresponding integrating device 7 will show the average integral expansion pressure.
Когда оба выключател 15 и 16 включены, то интегрируюищй пртбор 7 показьшает разность между среднеиитегральными давлени ми расщиреии и сжати , т.е. среднее индикаторное давле1ше.When both switches 15 and 16 are turned on, the integrative product 7 shows the difference between average and integral expansion and compression pressures, i.e. average indicator pressure.
