Description
рации сетевых помех, масштабирующего усилител 3, широкополосных филь ров 4 и 5 до 10 кГц и от 12 кГц соответственно дл проведени селекции по частоте, пиковых детекторов 6 и 7 дл измерени максимальных. амплитуд, схемы вычитани 8 и регистратора 9.network jamming, scaling amplifier 3, wideband filters 4 and 5 up to 10 kHz and from 12 kHz respectively for frequency selection, peak detectors 6 and 7 for measuring maximums. amplitudes, subtraction schemes 8 and recorder 9.
Устройство работает следующим образом.The device works as follows.
Поступающим от вибропреобразовател , соединенного с провер емыми распылител ми форсунок, входной сигнал преобразуетс нормализатором 1, затем отфильтровываетс от сетевых помех фильтром-пробкой 2, усиливаетс в масша-абирующем усилителе 3 и подаетс на входы широкополосных фильтров 4 и 5 дл производства селекции сигнала по частоте. Затем пиковыми детекторами 6 и 7 производитс измерение максимальных амплитуд поступающих сигналов с выходов широкополосных фильтров 4 и 5, посл чего сигналы, поступающие с выходов пиковых детекторов б и 7, подаютс на схему вычитани 8 и далее на регистратор 9.The input signal is converted by the normalizer 1 by the vibrating converter connected to the injector nozzles being sprayed, then filtered from the network noise by the filter plug 2, amplified by the scaler 3 and fed to the inputs of the wideband filters 4 and 5 to produce signal frequency selection . Then the peak detectors 6 and 7 measure the maximum amplitudes of the incoming signals from the outputs of the wideband filters 4 and 5, after which the signals from the outputs of the peak detectors b and 7 are fed to the subtraction circuit 8 and then to the recorder 9.
Полученна в результате обработки сигналов разность максимальных амплитуд сравниваетс с эталонными зависимост ми (эти зависимости изображены на фиг. 1 и фиг. 2), отклонение от которых свидетельствует о состо нии распылителей форсунок.The resulting signal processing difference in maximum amplitudes is compared with the reference dependencies (these dependences are shown in Fig. 1 and Fig. 2), the deviation from which indicates the state of the nozzles sprayers.
Внедрение предлагаемого способа позволит более чем в 3 раза сократить врем на диагностирование распылителей форсунок, в 2 раза снизит затраты на производство диагностики дизельного двигател , своевременноThe introduction of the proposed method will allow more than 3 times to reduce the time for the diagnosis of injector nozzles, 2 times reduce the cost of production of diagnostics of a diesel engine, timely
вы вл ть состо ние распылителей форсунок на работающем двигателе, что положительно скажетс на его топливо-экономических показател х.detecting the status of injector nozzles on a running engine, which will have a positive effect on its fuel-economic indicators.
