Having established new candles after small run (about 1000 km), it is expedient to unscrew them, having marked cylinder number, and attentively to examine a condition of insulators. At correctly chosen kalilny number both optimum structure of a mix and coal of an advancing of ignition the insulator will be light brown, brown or light gray.

Multi-colored deposits on an insulator and electrodes testify to existence in fuel or engine oil of a large number of additives. A black, opaque deposit on an insulator, electrodes and the case – a work sign on the majority of modes on the reenriched mix or too high kalilny number. It is necessary to check adjustments of the carburetor or injection system (for example on a gas analyzer) or to establish hotter candle. The brilliant black deposit testifies to hit in the greasing cylinder through piston rings and directing plugs of valves. Engine repair is required.

If the insulator of "snow-white" coloring – means, the candle worked at a maximum permissible thermal mode. Reasons: too earlier ignition, repauperization of a mix or too "hot" candle for this engine. It is necessary to check adjustments of the carburetor, the characteristic of the machine gun of an advancing of ignition and if they in norm, to put "colder" I shine. Well and the following degree of an overheat of a candle – the melted-off electrodes of a candle (it is good that not burned through bottom of the piston).

It can sometimes appear that all candles of one brand in different cylinders have insulators different in color. The reasons can be a little. As a rule, in carburetor engines a mix (on structure) and anti-detonation additives on cylinders are distributed non-uniformly.

Engines meet various sizes of extent of compression for each of cylinders. Well and between engines of one model extent of compression differs sometimes on the whole unit. At the expense of a deviation from technological processes, materials, etc. among candles of one brand the wide spacing on the actual kalilny numbers also is observed. At a big difference in a condition of candles sometimes it is necessary even to establish in one engine candles with different kalilny numbers. Always to have a stock on kalilny number in various service conditions, it is expedient to have two sets of candles and to establish in the summer "colder", and in the winter "hot".

Lately a number of firms lets out candles with an expanded thermal field of a candle. For this purpose the central electrode becomes copper, the covering from heat resisting materials (nickel, chrome) from above is put. Sometimes and lateral electrodes become from metal with good heat conductivity and a heat resisting covering. Other original decision is manufacturing of a tiny central electrode from the platinum, not acting of an insulator. Especially "cold" candles with kalilny number 300 and above for the forced engines (with турбонаддуовм, duple, etc.) are usually made with a silver electrode of small diameter and a short skirt of an insulator. Before establishing such candles, it is sometimes recommended to warm up at first the engine on hot candles and only then to establish the cold.

It is necessary to mean that when cleaning candle in the peskostruyny device the insulator surface collapses. Better, having overturned a candle, to fill in in the case solvent, gasoline or to apply a special aerosol ballonchik. Then a wooden stick to clear an insulator and to blow it the compressed air.
