Руководства по ремонту ЯМЗ

Обращаем Ваше внимание, что руководства по ремонту постоянно дорабатываются и
обновляются. Имеющиеся на данной странице руководства имеют последнюю редакцию, а
значит могут отличаться от документов выпущенных ранее и поставленных в комплекте с
двигателем. Поэтому при пользовании документами обращайте внимание на год его
издания.

    Dear Customer, The powerful and cost-effective powertrains and engines which you are beginning to use are reliable and easy to operate. However, it should be remembered that their lifetime largely depends on their regular and careful maintenance. Therefore, before starting operation, please CAREFULLY read this manual and strictly follow the rules…
  • Page 4: Warning

    WARNING 1. Failure-free functioning of the engine and its long operating life depend directly on their correct handling. Therefore carefully read this manual before starting the operation. 2. During the engine break-in period its mating parts become aligned, therefore further working efficiency largely depends on how strictly the rules specified in the NEW ENGINE BREAK-IN section have been followed.

    BASIC PARTS CYLINDER BLOCK AND CYLINDER LINERS The six-cylinder block is made of grey cast iron. It serves as a mounting base for all engine parts and units. Each cylinder liner seat bore has a circular groove for the liner collar in the upper part and a cylinder-shaped hole in the lower part made coaxially.

    LUBRICATION SYSTEM The engine lubrication system is a mixed-type wet-sump system. The oil pump sucks oil from the oil sump through the suction pipe intake and a safety valve and supplies it to the system through the in-line liquid-oil heat-exchanger (L/O HE) and the oil filter (OF). The L/O HE is installed in the service module housing which also incorporates the lubrication system differential valve, the water pump and the thermostat box.

Датчик частоты вращения коленчатого вала, также называемый датчиком скорости двигателя или датчиком синхронизации, установлен в верхней части картера маховика с правой стороны, если смотреть со стороны маховика. С помощью датчика частоты вращения коленчатого вала определяется частота вращения и угловое положение коленчатого вала (положение поршня) относительно верхней мёртвой точки (ВМТ) в цилиндрах двигателя. Используя информацию с датчика, ЭБУ двигателя рассчитывает начало подачи и количество впрыскиваемого топлива для каждого отдельного цилиндра.

ОТКАЗ ДАТЧИКА ПОЛОЖЕНИЯ ПЕДАЛИ ТОРМОЗА И СЦЕПЛЕНИЯ ЯМЗ 5340 / 536 И ИХ МОДИФИКАЦИЙ

Датчик положения педали тормоза – это контактный датчик, определяющий положе-ние педали рабочего тормоза (педаль нажата или не нажата). Функцию датчика может выполнять как отдельный датчик, устанавливаемый под педаль тормоза, так и выключатель стоп-сигнала («лягушка»), устанавливаемый в контуре низкого давления пневматической тормозной системы.

ОТКАЗ КНОПКИ МОТОРНОГО ТОРМОЗА ЯМЗ 5340 / 536 И ИХ МОДИФИКАЦИЙ

Моторный тормоз – это вспомогательная тормозная система, ограничивающая скорость движения автомобиля на длительных спусках. Выполняется она не зависимой от рабочей тормозной системы и в конечном итоге увеличивает срок службы тормозных накладок, так как отсутствует их износ и разогрев. В качестве тормоза-замедлителя на каждом ТС можно использовать двигатель, работающий как воздушный компрессор.
