5.5. Ignition system

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

For definition of the moment of ignition the management block uses the information stored in memory and the information from gauges, established on the engine. The ignition system receives operating signals from the gauge of the Hall or the pulse gauge. In addition the ignition moment is corrected also on a signal of the gauge of a detonation which is sensitive to premature ignition and, accordingly, reduces a corner of an advancing of ignition.
Engines Recommended fuel/ROZ Admissible fuel
4-4 - And 5-titsilindrovye engines Super neetilirovannyj/95 Normal neetilirovannyj/91
The engine 2,8-I-V6 Super neetilirovannyj/98 Normal neetilirovannyj/95

At car refuelling by admissible fuel, capacity of the engine decreases at increase in the expense of fuel. Also it is not recommended to maintain the engine on the maximum modes.

The oktanovoe number of fuel defines antidetonation properties of fuel.


At work on ignition system not to damage semi-conductor devices (diodes and transistors), is necessary to fulfil following requirements:

 – In an operating time of the engine do not disconnect the accumulator, the generator or any electric sockets;
 – At carrying out of any works remove the negative plug from the accumulator;
 – At carrying out of electrowelding works on the car disconnect the generator and the management block;
 – Do not suppose work of the engine with the generator disconnected from electric system.

Do not concern high-voltage wires with a hand and do not disconnect them at the working engine or at проворачивании a cranked shaft of the engine a starter.

Wires of system of ignition and wire of measuring devices disconnect only at the switched off ignition.

Engine sink make only at the switched off ignition.
