6.1. Power supply system

General information and security measures

Into structure of a power supply system enter: established in a back part of the car a fuel tank, a coal absorber of fuel evaporations, топливопроводы, the electric fuel pump, and also the electronic system of the distributed consecutive injection operated by the electronic control unit by the engine (ECM).

Essential influence on fuel consumption renders style of driving of the car. Some councils on economy of gasoline below are given.

  • After engine start at once get under way from a place even if it occurs on a frost;
  • At a car stop more long, than on 40 with, switch off the engine;
  • Move always on the most admissible high transfer;
  • At movement on big distances whenever possible support uniform speed. Avoid movement on high speeds. Without need do not brake;
  • Do not transport on the car excessive cargo;
  • Check pressure of air in tires. Do not allow excessive pressure decrease.

Security measure and purity observance at work with fuel system

  • Do not work with fuel system near open fire, do not smoke thus and do not turn on heating devices! Keep in readiness the fire extinguisher;
  • Before the work beginning with fuel system always disconnect a negative wire from the battery in order to avoid emergence of sparks. Before shutdown of the battery it is necessary to consider codes of malfunctions (see. Head of System of electric equipment of the engine);
  • Watch normal ventilation of a workplace, – fuel pairs are poisonous;
  • Do not allow gasoline hit on rubber and leather surfaces since thus they can be damaged;
  • The fuel system is under pressure and at its opening fuel can escape, - use goggles. The spilled fuel collect rags;
  • Shlangovye connections fasten by means of tape or tightening collars. When dismantling it is necessary to replace tightening collars tape;
  • Connections and places adjoining to them before opening carefully clear;
  • The removed components stack on a pure lining and cover with polyethylene, paper or неворсящейся rags;
  • Close open shtutserny sockets, for example, suitable caps;
  • Establish only pure details, - replaceable components take from packing directly ahead of installation. Do not use the details stored unpacked;
  • Avoid application of the compressed air at open fuel system, whenever possible try not to move the car;
  • Do not apply hermetics containing silicone since the particles which have got to the engine of silicone do not burn down and can be at the bottom of failure a lambda probes;
  • Before removal of a fuel tank pump out from it fuel pump specially intended for this purpose;
  • Remember that even the empty fuel tank remains explosive;
  • After installation of components of fuel system start the engine and check tightness of all connections.
