Description

чины цикловой подачи топлива на режиме пуска.start cycle fuel on start mode.

Далее датчик перенос т на диагнос тируемую форсунку на двигатель, осуществл ют его запуск и измер ют отношение мощности вибрации к ее длительности . Показани  прибора, наход щиес  внутри установленного диапазона , свидетельствуют об удовлетворительном техническом состо нии форсунки , выход результатов за пределы диапазона указывает на недопустимое техническое состо ние форсунки.Next, the sensor is transferred to the diagnosed injector on the engine, it is started, and the ratio of the vibration power to its duration is measured. Instrument readings that are within the specified range indicate a satisfactory technical condition of the nozzle, and the out-of-range result indicates an unacceptable technical condition of the nozzle.

Поскольку при изменении величины цикловой подачи топлива вследствие ухудшени  технического состо ни  топливного насоса мощность и длительность вибрации измен ютс  линейно, то их отношение должно оставатьс  посто нным , исключа  тем самым вли ние Масоса на диагностическую оценкуSince the power and duration of vibrations change linearly when the magnitude of cyclic fuel supply changes due to deterioration of the technical condition of the fuel pump, their ratio should remain constant, thereby eliminating the influence of Masos on the diagnostic evaluation
