Изобретение относитс к контрольно-измерительной технике и может быть использовано при испытани х и эксплуатации поршневых машин, в частности при испытании двигателей внутреннего сгорани .The invention relates to instrumentation engineering and can be used in testing and operating piston machines, in particular in testing internal combustion engines.
Известны устройства дл контрол индикаторр|ых диаграмм поршиевых машин 1. Такие устройства характеризуютс получением разверпутой индикаторной диаграммы и обеспечением ее обработки по тому или иному алгоритму. Они содержат датчик давлени , устанав.шваемый в цилиндре двигател , вычислительное или преобразующее устройство, обеспечивающее контроль или вычисление заданного параметра , и управл ющее устройство, обеспечивающее синхронизацию по углу поворота коленчатого вала, по ходу движени поршн или по времени.Devices are known for monitoring the indicator diagrams of the porsche machines 1. Such devices are characterized by obtaining an unfolded indicator diagram and ensuring its processing according to one or another algorithm. They contain a pressure sensor that is installed in the engine cylinder, a computational or conversion device that controls or calculates a given parameter, and a control device that synchronizes the rotation angle of the crankshaft, along the motion of the piston or over time.
Одновременное индицирование всех цилиндров многоцилиндровых двигателей и обработка полученных диаграмм (индикаторных ) сопровождаетс увеличением номенклатуры средств контрол и измерений, что существенно повьипает трудоемкость испытаний .Simultaneous indexing of all cylinders of multi-cylinder engines and processing of the obtained diagrams (indicator) is accompanied by an increase in the range of means of control and measurement, which significantly increases the laboriousness of the tests.
Наиболее близким к изобретению по технической сущности и достигаемому рсз :1ьтату вл етс устройство дл измерени среднего индикаторно1Ч) давлени в двигател х внутреннего сгорани , содержап1ее датЧ1 к дл измерени давлени рабочих газов с измерительным усилителем, датчик угла поворота коленчатого вала, вычислите,1ьное устройство, 6.1ОКИ выде.ени имиульсов и блок уиравлени 2.The closest to the invention to the technical essence and the achieved RSD: One hundredth is a device for measuring the average indicator pressure in internal combustion engines, containing a sensor for measuring the pressure of working gases with a measuring amplifier, crankshaft angle sensor, calculate 6.1OKI highlighting of emulsions and unit 2.
Недостатком этого устройства вл етс сложность, необходимость прив зки к коленчатому валу двигател , неудобство и неоперативность в эксплуатации.The disadvantage of this device is the complexity, the need to bind to the crankshaft of the engine, inconvenience and inoperability in operation.
Целью изобрете1П1 вл етс ynponienne устройства.The purpose of the invention of the P1 is the ynponienne device.
Это достигаетс тем, что в устройстве дл контрол среднего индикаторного давлени в цилиндрах порщневых машин, содержащем последовательно соединенные датчик давлени , уси.чптель, преобразователь напр жение - частота, логическую схему совпадений и регистрирующий счетчик, блок управлени , выход которого подключен к логической схеме, блок управлепи выполнен в виде последовательно соединенныхThis is achieved by the fact that in the device for monitoring the average indicator pressure in the cylinders of the pressure machines, containing in series a pressure sensor, a voltage sensor, a voltage-frequency converter, a matching logic and a registering counter, the control unit, the output of which is connected to the logic circuit, control unit is made in the form of serially connected
