Ignition and engine management systems

Main data and security measures

The system of ignition provides ignition submitted to chambers of combustion of cylinders of an air and fuel mix. For formation of a spark of demanded intensity 12-volt tension of onboard power supply in will be transformed ignition coils to high-voltage (VV), - 30 000 Century.

The electronic system of direct ignition is an integral part of a control system of the engine. The main working components of system of ignition are candles and ignition coils.

Distribution of giving of VV of tension to spark plugs on candles the block of electronic control (ECM) operates.

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

Elements of management of system of ignition are not subject to wear and regular service do not need. According to the maintenance Schedule (see. Head of the Power supply system and production of the fulfilled gases) it is necessary to make only replacement of spark plugs.

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

For the purpose of prevention of a travmirovaniye of the personnel and/or failure of components of systems of ignition/management by injection it is necessary to observe the following:

  • Do not touch electroconducting of system of ignition and do not disunite its contact sockets at the working engine / a rotating starter;
  • Make detachment/connection топливопроводов control systems of injection/electroconducting of system of ignition, and also connection/shutdown of any diagnostic and measuring equipment only at the switched-off ignition;
  • Do not allow to works on service by electronic system of ignition of people with the implanted pacemaker;
  • Do not allow short circuit on mass of No. plugs of 1 coils of ignition;
  • Do not connect a control lamp to No. plugs of 1 coils of ignition.
