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 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.

The scheme of an arrangement of the main components of system of ignition on petrol models (1 of 4)

B2/5 — the MAF/MAF Sensor + IAT
B6/1 — the Hall Sensor (the provision of a camshaft)
B11/4 — the Sensor of temperature of cooling liquid (CTS)
В28 (only М113) — the pressure Sensor
L5 — the CKP Sensor

М33 — the Air pump
T1/1 ÷ T1/6/7/8 — the Coil of ignition of the corresponding cylinder
Y32 — the Valve switch of the air pump
Y62 — Fuel injectors

The scheme of an arrangement of the main components of system of ignition on petrol models (2 of 4)

A16/1 — the Left sensor of a detonation (KS 1)
A16/2 — the Right sensor of a detonation (KS 2)
В40 — the Sensor of level/temperature/quality of oil
M16/6 — the Activator of a drive of a butterfly valve

Y22/6 — the Valve switch of a drive of change of geometry of the inlet pipeline
Y31/1 — Vacuum a transdyuser of EGR

The scheme of an arrangement of the main components of system of ignition on petrol models (3 of 4)

К40 — the Assembly block of safety locks/relay:
f2 — the Safety lock of a contour 87
f3 — the Safety lock of a contour 87
f4 — the Safety lock of the air pump
k1 — the Relay of the fuel pump
k6 — the Relay of the air pump

k9 — the Relay of a contour of the 87th engine
N3/10 — ECM ME-SFI
N15/3 — TCM
N47-7 — the Module of management of ABS
N36 — the Ballast of the sensor of target turns of transmission

The scheme of an arrangement of the main components of system of ignition on petrol models (4 of 4)

В37 — the Sensor of provision of a pedal
G3/3 — Left dokataliticheskiya a lambda probe

G3/3 — Right dokataliticheskiya a lambda probe

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 the Current leaving and service) it is necessary to make only replacement of spark plugs.

The main data and illustrative material on work and sensors of control systems and injection of fuel of petrol and diesel engines are stated in Sections the Principle of functioning of a control system and injection of the petrol engine and General information.

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. No. plugs of 1 coils of ignition;
  • Do not connect a control lamp to No. No. plugs of 1 coils of ignition.
