7.1.1. Main data and security measures

Main data and security measures

The system of ignition provides ignition submitted to chambers of combustion of cylinders of petrol engines of an air and fuel mix. For formation of a spark of demanded intensity 12-volt tension of an onboard network will be transformed in ignition coils to high-voltage tension.

The electronic system of ignition is an integral part of a control system of the engine. Its main working components are candles, coils and ignition modules. Giving distribution In/in tension on spark plugs the block of electronic control operates the engine (ECM).

Manual adjustment of the moment of ignition is not made, – at violation of demanded installations it is necessary to make replacement of the failed components.

Components of system of ignition are not subject to wear and regular service do not need. According to the maintenance schedule (see. Head of Control and routine maintenance of the car) it is necessary to make only replacement of spark plugs.

The main data on work and sensors of control systems of the engine and injection of fuel are stated in Head of the Power supply system and production of the fulfilled gases.

Security measures at work with systems of ignition and management of fuel injection

For the purpose of prevention of a travmirovaniye and/or failure of components of electric and electronic systems it is necessary to observe the following:

  • Do not touch electroconducting of system of ignition and do not separate its sockets at the working engine / a rotating starter;
  • Make detachment/connection топливопроводов control systems of injection, electroconductings of system of ignition, and also any diagnostic and measuring equipment only at the switched-off ignition;
  • Works on service by electronic system of ignition by people with the implanted pacemaker are not allowed.
