Spark plugs replace at planned maintenance.
If it is necessary to replace ever spark plugs not at planned maintenance, it is necessary to take the following into account.
Spark plugs and all system of ignition in general are picked up to this engine, and it promotes decrease in amount of harmful substances in the fulfilled gases.
To avoid failures of the engine, decrease in its power, deterioration in acceleration performance, increase in content of harmful substances in the fulfilled gases and creations of hindrances for radio reception, it is necessary to apply only the spark plugs recommended by the Volkswagen Group to this engine. Especially important characteristics of candles are the quantity of electrodes, kalilny number and in some cases ability not to create hindrances to radio reception.
The correct functioning of spark plugs – one of the most important conditions of effective operation of the engine. It is necessary that on the engine spark plugs only the ordered type were established. At the serviceable engine cleaning of spark plugs – rare operation.
Arrangement of screws (1) of fastening of the top casing of the engine 1,6-I
Arrangement of tips (2) high-voltage wires on spark plugs
Arrangement of brackets (1) of fastening of the top casing of the engine 1,8-I
Arrangement of tips of high-voltage wires on spark plugs of the engine 1,8-I
Engines 2,3-I (5 cylinders)
Arrangement of tips of high-voltage wires on spark plugs of the engine 2,3-I
Engines 2,8-I (6 cylinders)
Arrangement of screws of fastening of the top casing of the engine 2,8-I
Visual control of a working part of spark plugs can show a condition of the engine. If the nasal part of the isolation center of spark plugs pure and white, without raid, then it testifies to too poor mix. It also specifies that a candle too hot, that is heat from the central electrode is taken away slowly. If this is so, then it is necessary to adjust composition of fuel mix or to replace a candle.
If the nasal part of the isolation center is covered with a black raid, then it means that mix too rich. If the raid black and oily, then is the witness stvut about wear of the engine and need of its check and repair. If the nasal part of the isolation center is covered with a light brown raid, then the composition of mix is optimum and the engine is in good shape.
The interelectrode gap of a spark plug is of great importance as at too big and at too small gap the spark size changes that leads to decrease in overall performance of the engine. The gap has to conform to technical requirements always.
Measurement of a gap of a spark plug probe
Check of a gap is carried out by a wire template or the probe. Correction of a gap is carried out by a podgibaniye of a side electrode. The central electrode cannot be bent at all as it can lead to breakage of the insulator and an exit of a candle out of operation.
For a podgibaniye of a side electrode of a candle it is necessary to use the special tool.
Before installation of a spark plug in the engine, check that the carving was pure and all threads of a carving whole.
Screw in spark plugs by hand and then tighten them the required moment.
Connect high-voltage wires to spark plugs.
