Ignition and engine management systems

The basic data and security measures

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

The electronic system of direct ignition is an integral part of a control system of the engine. The basic working components of system of ignition are candles and ignition coils. Distribution of giving В/В of pressure to spark plugs the electronic control block (ECM) operates.

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

Elements of management of system of ignition are not subject to deterioration and regular service do not require. According to the maintenance service schedule (see the Head of Adjustment and car routine maintenance) it is necessary to make only replacement of spark plugs.

The basic data on work and gauges of control systems of the engine and fuel injection are stated in the Head of the Power supply system and release of the fulfilled gases.

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

For the purpose of prevention травмирования 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 separate its sockets at working dvigatele / a rotating starter;
  • Make a detachment/connection топливопроводов control systems of injection/electroconducting of system of ignition, and also connection/switching-off of any diagnostic and measuring equipment only at the switched off ignition;
  • Performance of works on service by electronic system of ignition by people with implanted кардиостимулятором is not supposed.
