System of ignition – the general information and precautionary measures (petrol models)

On the models considered in the present manual the system of direct ignition without distributor and high-voltage wires is used.

Sensors of provision of distributive and cranked shaft (CMP and ICR), set individual for each of cylinders of coils of ignition and the ignition module are a part of systems of direct ignition. The onboard processor (ESM) develops the basic signals defining an order of connection of the module of ignition to each of coils according to the current provision of a bent shaft. Installation of a corner of an advancing of ignition is carried out by the module of management on the basis of the analysis of the signals arriving from various information sensors which are a part of systems of ignition and injection of fuel. Here ECT, VSS, TPS sensors, provisions of AT, the expense measuring instrument the MAF air/sensor, the detonation sensor enter (see the Head of the Control system of the engine and decrease in toxicity of the fulfilled gases). The module of ignition carries out distribution of a signal between coils and controls duration of impulses of their operation (on primary current).

At service of systems of direct ignition it is necessary to observe special precautionary measures:
   
   a. If the engine is not started, do not hold the ignition key ON which are continuously turned in situation within more than 10 seconds in a row;
   b. You watch that connection of a tachometer was carried out strictly according to instructions of manufacturers, some of the released measuring instruments can not be suitable for use on these models;
   c. Do not allow grounding of contact plugs of coils of ignition on weight at all, – the slightest imprudence in this question can lead to failure of the module of ignition and/or actually coils;
   d. Do not disconnect the battery at the working engine;
   e. You watch for correctness of grounding of the module of ignition.
