Spark plugs replace at planned maintenance.
If it is necessary to replace ever spark plugs not at planned maintenance, it is necessary to take into consideration the following.
Spark plugs and all system of ignition as a whole are picked up to this engine, and it promotes decrease in quantity of harmful substances in the fulfilled gases. To avoid failures of the engine, decrease in its capacity, deterioration of acceleration performance, increase of the content of harmful substances in the fulfilled gases and creations of hindrances for radio reception, it is necessary to apply only recommended by concern spark plug Volkswagen 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.
There are two types of consolidations at installation in a cylinder head: with a flat saddle and elastic (steel or copper and asbestine) laying or with a conic saddle without laying. At installation of a new candle first of all it is necessary to check, what consolidation is provided in a cylinder head, and also diameter and length of a carving part. If to establish a candle with a long carving part in a head with a short carving, the acting part of a candle will become covered by a deposit and pitches, lead deposits. The candle will overheat, probably oplavleny carvings. At a reversing of a candle it is possible to damage because of it a carving in a cylinder head. At a short carving part of a candle and long in a head the deposit and various deposits hammer a carving, there is its oplavleniye. After long work it is necessary to pass a tap a carving part in a cylinder head but so that dirt did not remain in the cylinder.
Depending on purpose of a candle have a number of design features. So, for cars and the motorcycles working in heavy road conditions when hit on the water engine is possible, and at increased requirements to level of a radio noise ekranirovanny candles with tight consolidation of a wire of a high voltage are applied. For the purpose of increase of stability of work of candles on the case some electrodes sometimes become or in general lateral electrodes are not present (with a floating electrode).
Depending on features of working process of a candle are carried out with the insulator drowned in the case or with acting insulator (for combustion chambers from an intensive turbolizatsiy mix in the combustion chamber).
In the major parameter characterizing a candle, the temperature mode of its elements, first of all – the central electrode and a surface of a skirt of an insulator is.
The main problem at candle creation for the high-speed engine is implementation of inconsistent requirements. On the one hand – to provide rather high temperature of a skirt of an insulator that at long work on small loadings and idling to prevent formation on it of the deposit leading to shunting, especially at low temperatures. Upon transition to big loadings at high temperatures there is a self-cleaning of an insulator of a candle at the expense of burning out of deposits on it.
On the other hand, at high numbers of turns and big loading the temperature of the central electrode and the lower part of an insulator should not exceed the top limit at which there is a kalilny ignition (mix ignition even before spark emergence from ignition system). From a cycle to a cycle ignition occurs all earlier and earlier, the temperature of details grows until something will not burn down – at the best a candle, in the worst – the piston. So because of a small candle there can be big troubles.
How to prevent possibility of emergence of kalilny ignition? First of all, it is necessary to watch for correct (according to the instruction) installation of corners of an advancing of ignition, without allowing too early ignition. At contact system the corner of an advancing of ignition can increase unexpectedly, for example, if jumps aside one of napayanny contacts of the breaker.
The second condition – always to fill in the gasoline corresponding to level of a forsirovka of the engine (extents of compression, to nominal frequency of rotation, filling, etc.). The octane number is lower, the it is more tendency to kalilny ignition. Well and if nizkooktanovy gasoline after all is filled in, it is impossible to leave on big loadings at high numbers of turns.
The third condition, sometimes the most important – to establish candles with demanded kalilny number according to the recommendation of manufacturer of the engine.
The designation of kalilny number at one time accepted by the majority of the European firms, on time (in seconds) after which at tests on special installation kalilny ignition begins is most convenient. In recent years the majority of firms passed to a symbol of kalilny number of candles.
