10.9.1. Features of the device
In system of ignition the traditional distributor is not used...
... here the chetyrekhvyvodny coil of ignition consisting of two dvukhvyvodny coils of ignition, united in one block is applied. The controler receiving information from sensors and using two powerful transistor gates operates a current in primary windings of coils of ignition.
The system of ignition does not include mobile details therefore does not demand service and does not need adjustments.
In system of ignition the method of distribution of the spark, called by a method of a single spark is applied. Cylinders of the engine are incorporated in pairs 1–4 and 2–3, the iskroobrazovaniye occurs at the same time in two cylinders: in the cylinder in which the compression step (a working spark), and in the cylinder in which there is a release step (a single spark) comes to an end.
Due to the constant direction of a current in windings of coils of ignition the iskroobrazovaniye current at one candle always proceeds from the central electrode on lateral, and at the second – with lateral on central.
The controler operates ignition in system. The sensor of provision of a cranked shaft gives a basic signal on the basis of which the controler counts sequence of operation of coils in the ignition module in the controler. For exact management of ignition the controler uses the following information:
– frequency of rotation of a cranked shaft;
– engine loading;
– temperature of cooling liquid;
– provision of a cranked shaft;
– provision of a camshaft;
– detonation existence.
