7.5. System of ignition - the general information
|
|
In the transistor electronic system of ignition used on the considered models of cars higher is generated, in comparison with characteristic of systems of ignition of usual type, tension. Be attentive, observe all necessary precautionary measures. |
The programmable system of ignition (PGM-IG) on the basis of the microprocessor provides continuous optimization of installation of a corner of an advancing of ignition depending on turns of the engine, temperature of cooling liquid, the provision of a butterfly valve and depth of depression in the inlet pipeline. All necessary data arrive on the module of management (ESM) from the corresponding information sensors, such as the TDC/CKP/CYP sensor, the sensor of provision of a butterfly valve (TPS), the sensor of temperature of cooling liquid and the sensor of absolute pressure in the pipeline (MAR). At an engine warming up, its work on single turns and under loading various installations of a corner of an advancing of ignition are used. The corresponding adjustments are carried out by the PGM-IG system. The ignition switch/lock, the rechargeable battery, the ignition coil, the distributor, a set of candles and VV of wires also are a part of system of ignition (see illustrations).
The ignition distributor on all models is put in action from the camshaft (on the Integra models – from the inlet camshaft). Correction of an advancing of ignition is carried out by the electronic module of management (ESM). On all models the distributor is equipped with the sensor of an angle of rotation. The description of procedures of failure diagnostics and check of serviceability of functioning of TDC/CKP/CYP sensors is provided in the Head of the Control system of the engine.
