Ignition and engine management systems
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 will be transformed in ignition coils in high-voltage (30 000 In).
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. Giving distribution In/in tension on spark plugs the block of electronic control (ECM) operates.
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.
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 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 of the personnel and/or failure of components of systems of ignition/management by injection it is necessary to observe the following:
