11.5.3. System of ignition of the engine of fashion. 2106
The engine is equipped with contact (classical) system of ignition with use of the distributor of ignition with the mechanical breaker.
The system of ignition battery, with a rated voltage in primary chain of 12 V, consists of the coil of ignition, the distributor, spark plugs, candle tips, the switch (lock) of ignition and wires of chains of low and high voltage.
Reliability and profitability of operation of the engine substantially depends on a condition of devices of system of ignition. When checking system of ignition on the car to pay attention to a condition of contact connections in chains of low and high voltage, and also to a condition of a surface of plastic details of covers of the distributor of ignition and the coil, cases of candle tips. Pollution of the specified surfaces can lead to leakage of current of a chain of high voltage and cause interruptions in operation of the engine.
For decrease in levels of the radio noise created by system of ignition during the work high-voltage wires with a ravnoraspredelenny resistance on length are installed on the engine.

The serviceable coil of ignition has to meet the following requirements:
– ohmic resistance of primary winding at 20 °C has to make 3,07–3,5 0 m, and a secondary winding – 5400–9200 0 m;
– when checking isolation on "weight" the coil of ignition has to maintain tension of the alternating current of 1500 V at 50 Hz given within 3 min. between one end of primary winding and the case without causing categories;
– isolation resistance on "weight" has to be higher or 50 megohms are equal.
