Visual check

 PERFORMANCE ORDER

  1. To begin with check up air lines on tightness! All hoses – from a thick sleeve of an air inlet to thin vacuum hoses should be checked.
  2. Whether as it should be sealing linings впрыскных atomizers, and also фланцевые linings of inlet channels?
  3. Not tight places open access to not considered air, that is air which is not considered by system and consequently essentially disturbs to mix preparation. The mix неконтролированно is impoverished. A consequence of it are malfunctions in the engine work, shown first of all in rough idling.
  4. To warm up the engine to working temperature, then to leave to work on single turns, to open a cowl, to separate plug connection to a ljambda-probe.
  5. To sprinkle from a spray containing starting fuel (for example «Startpilot») sealing фланцевые linings of inlet channels and other details inspiring suspicion.
  6. If frequency of rotation changes at spraying of a certain place, means, there has arisen негерметичность.
  7. Whether it is possible to distinguish негерметичность топливопроводных hoses?
  8. Whether tips of wires have been repeatedly separated and again connected? Corrosion or inept actions can lead to insufficient contact.
  9. Attentively consider tips of separate components of system of injection. They can be processed only a contact spray, but not to bend at all that can cause malfunctions.
