5.5. System of ignition

GENERAL INFORMATION

The system of ignition creates in each cylinder of the engine at some point the spark category which ignites the compressed fuel mix. For formation of a spark in the ignition coil tension of the battery of 12 V will be transformed to the high voltage of ignition of 25 000-30 000 Century.

For definition of the moment of ignition the control unit uses information which is stored in memories and information from the sensors installed on the engine. The system of ignition receives the operating signals from Hall's sensor or the pulse sensor. In addition the moment of ignition is corrected also on a detonation sensor signal which is sensitive to premature ignition and, respectively, reduces an ignition advancing corner.
Engines The recommended fuel/ROZ Admissible fuel
4-h-and 5-titsilindrovy engines Super unleaded / 95 Normal unleaded / 91
Engine 2,8-I-V6 Super unleaded / 98 Normal unleaded / 95

During filling the car with admissible fuel, engine capacity at increase in fuel consumption decreases. Also it is not recommended to operate the engine on the maximum modes.

The octane number of fuel defines anti-detonation properties of fuel.

Precautions

At work on system of ignition not to damage semiconductor devices (diodes and transistors), it is necessary to fulfill the following requirements:

 – in operating time of the engine do not disconnect the accumulator, the generator or any electric sockets;
 – when carrying out any works remove the negative plug from the accumulator;
 – when carrying out electrowelding works on the car switch-off the generator and the control unit;
 – do not allow operation of the engine with the generator disconnected from electric system.

Do not touch high-voltage wires by a hand and do not disconnect them at the working engine or at a provorachivaniye of a bent shaft of the engine a starter.

Disconnect wires of system of ignition and a wire of measuring devices only at the switched-off ignition.

You make a wash of the engine only at the switched-off ignition.
