7.1. Systems of ignition and engine management

Main data and security measures

The system of ignition provides ignition of the air-fuel mix given to combustion chambers of cylinders. For formation of a spark of the required intensity the 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 coils of ignition. Distribution of giving of VV of tension to spark plugs on candles the block of electronic control (ECM) operates.

B37 — 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 the required installations it is necessary to make replacement of the failed components.

Elements of management of system of ignition are not subject to wear and do not need regular service. According to the Schedule of maintenance (see the 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 the Sections Principle of Functioning of a Control System and Injection of the Petrol Engine and General Information.

Security measures during the work with systems of ignition and management of fuel injection

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