Изобретение относитс к снособам диагиостаки двигател внутреннего сгорани на бестормозных испытани х.This invention relates to diagostaki methods for an internal combustion engine in a brake-free test.
Из|Вестеп способ диагностики двигател внутреннего сгорани во врем испытании иутем выключени р да его цилиндров из работы и догрузки работающих цилиндров до заданного уравп с помощью дополнительных догрузочных устройств, например, гидравлической системы трактора.From the Westep method of diagnosing an internal combustion engine during testing and by turning off a number of its cylinders from work and reloading working cylinders to a predetermined level using additional load devices, for example, the hydraulic system of a tractor.
Однако технологи испытании при определении показателей каждого цилиндра по известному сиособу сложна. Эта сложност) заключаетс в том, что работа на номинальных оборотах на одном работающем цилиндре миогоцилиндрового двигател невозможна ввиду большой мощности механических потерь выключенных из работы цилиндров. Поэтому дл определени показателей каждого цилиндра требуютс многократные последовательные испытани с различным сочетапием отключаемых цилиндров, что трудоемко и понижает точПость определени показателе одного цилиндра.However, test technologists in determining the performance of each cylinder according to a known method are complex. This difficulty lies in the fact that working at nominal speeds on one working cylinder of a Myo-cylinder engine is impossible due to the high power of mechanical losses that are turned off from the operation of the cylinders. Therefore, to determine the performance of each cylinder, multiple sequential tests are required with different combinations of cylinders to be disconnected, which is laborious and lowers the accuracy of determining the rate of one cylinder.
Целью изобретени вл етс упрощеиие технологии оценки показателей каждого отдельного цилиндра двигател .The aim of the invention is to simplify the technology of evaluating the performance of each individual engine cylinder.
Это достигаетс тем, что нри бестормозных испытани х двигател по предлатаемому способу выключают из работы все цилиндры,This is achieved by the fact that in engineless engine tests, by the preferred method, all cylinders are shut down,
кроме одного, устанавливают на него заданную нагрузку и поддерживают необходимое число оборотов подкруткой вала двигател от постороннего источника энергии.except for one, they set a predetermined load on it and support the required number of revolutions by twisting the engine shaft from an unauthorized energy source.
Дл диагностики двигател , например, трактора по предлагаемому способу в полевых услови х предварительио обеспечивают передачу крут щего момента на вал отбора мощности трактора от двигател , нанрнмер, автомобил через коробку отбора мощности, раздаточную коробку автомобил , карданные налы, измеритель момента и оборотов. Па диагностируемом двигателе тра -:тора выключают все цилиндры, кроме одного, устанавливают на работающий цилиндр необходимую нагрузку , поддержива необходимое число оборотов нодкрутко вала двигател трактора or двигател автомобил . Л1о цность испытуемого цилиндра Лц определ етс по мощности трени диагностируемого двигател .V и добавочной мощностн Ад,1,1, иодводимой от двигател автомобил , по соотион1ениюTo diagnose an engine, for example, a tractor according to the proposed method, in field conditions, preliminary transmission of torque to the tractor's power take-off shaft from the engine, nanometer, car through the power take-off box, car's transfer case, cardan shafts, torque and speed meter. Pa diagnosed engine tra - torus off all cylinders, except for one, set on the working cylinder the necessary load, maintaining the required number of revolutions nodkrutko shaft of the tractor engine or car engine. The value of the test cylinder Lz is determined by the power of the friction of the engine being diagnosed .V and the additional power, Hell, 1.1, given by the engine of the car, according to
