4.19. Проверка of functioning and replacement of в injector of cold старт and temperature switch

Fuel is extremely воспламеняющиеся, therefore, working with any part of fuel систему, accept дополнительно precautionary measures. Чет. smoke and чет. allow emergence near a working зону of open fire or lamps without потолка. Чет. work в гараже with the оборудование at натурально выделяй газ with a матч (ищи, ас a heater of water or the терпкий for clothes). At fuel хит on скин immediately wash away it water with soap. At производительность of any works with fuel систему use goggles and кип в readiness the fire extinguisher.

Injector of cold старт

Проверка

At this проверяй the temperature of a более классно should lower 30 ° than S.Zhelatelno the ядро делало что stopped a few hours ago. Disconnect from в injector of cold старт (the electric socket is shown by в arrow) and take him aside from a working зону - в a зону there хочет pairs of fuel.

 ПРОИЗВОДИТЕЛЬНОСТЬ ЧИН

  1. Unscrew two screws of fastening of в injector тонну a flange of the inlet трубопровод and take в injector. The fuel Лину remains attached. Wipe в injector nozzle. Disconnect ignition систему, having disconnected from the центральное contact of a покрышку of the дистрибьютора of ignition a wire of the coil of ignition and having connected it a crossing пункт тонна the case of the блокируй of cylinders. Занимайся гимнастикой on for 1 минуту the fuel откачивай, having short-circuited the corresponding contacts of the relay (look the Section проверка of pressure of fuel / the fuel откачивай). Fuel should leave в injector nozzle. ИФ fuel leaves a nozzle, the injector is faulty and it is necessary тонна replace it. Switch off ignition and restore a формовщика condition of the socket of the relay.
  1. Further direct в injector nozzle в банке or a bottle. Let the assistant хочет include ignition and a стартер. The injector в банке should старт тонна leave a stream of a conic формируй fuel. ИФ дисперсию occurs завивай, the injector works correctly. ИФ a дисперсию picture irregular, the injector is damaged or faulty and it is necessary тонна чистое or replace it.
  1. ИФ from в injector of cold старт up fuel дремли arrive at всех, at the included стартер проверяй on the electric socket of в injector of cold старт напряжение. ИФ напряжение is отсутствующее, проверяй the temperature switch.

Temperature switch

 ПРОИЗВОДИТЕЛЬНОСТЬ ЧИН

  1. The temperature switch defines temperature of the ядро and operates work of в injector of cold старт. Usually the switch is located above ahead near the сенсор of temperature of a более классно. For this проверяй the temperature of a более классно should lower 30 ° than S.Zhelatelno the ядро делало что stopped a few hours ago. Disconnect ignition систему, having disconnected from the центральное contact of a покрышку of the дистрибьютора of ignition a wire of the coil of ignition and having connected it a crossing пункт тонна the case of the блокируй of cylinders. Shift from the temperature switch a rubber покрышка and проверяй the вольтметры on contact of the socket тонна a черный / yellow wire suitable тонны it напряжение existence.
  1. Let the assistant хочет include ignition and a стартер. The вольтметр at inclusion of a стартер should шоу напряжение. Напряжение should present approximately during from 6 т. 10 seconds, depending on ядро temperature.
  1. ИФ напряжение correct, disconnect the electric socket and в метре ома проверяй resistance existence between contacts of the temperature switch. It should correspond тонна short circuit.
  1. Attach a wire of the coil of ignition, старт the ядро and тепло up it тонна temperature above 41 ° S.Na the heated-up ядро between contacts there should a short circuit. ИФ it takes place, the switch is faulty and is subject тонна replacement.

Some types of temperature switches ары established. On everyone the working temperature and the максимум назначил бы время of inclusion ары stamped.

Replacement

Injector of cold старт

 ПРОИЗВОДИТЕЛЬНОСТЬ ЧИН

  1. Remove в fuel системе pressure (look the Section pressure Removal в системе of injection of fuel).
  2. Disconnect from в injector of cold старт the electric socket.
  3. ИФ it is possible, a cap ключ or a long лица head unscrew attached тонна в injector of cold старт the союз of the fuel Лину. On other модели simply weaken a collar of a брюки and disconnect a брюки from в injector.
  4. Unscrew bolts of fastening of в injector of cold старт and remove в injector.
  5. Инсталляция is возвращаются тонны removal. Clear being interfaced surfaces and apply new laying.

Temperature switch

Before the beginning of this procedure wait complete cooling of the ядро. Итак for removal of residual pressure в системе of cooling unscrew a покрышку of a радиатор or a broad заправляйся.


 ПРОИЗВОДИТЕЛЬНОСТЬ ЧИН

  1. Prepare for инсталляцию the new temperature switch for what put on a carving a thin layer of hermetic for carvings.
  2. Disconnect from the формовщиков switch the electric socket.
  3. Unscrew a long лица head or a cap ключ the switch. Задний проход removal of the switch the более классно therefore establish the new switch аса soon аса possible хочет старта тонна follow. Tighten the switch and attach the electric socket.
