Spark plugs - the general description

THE GENERAL DATA

Interelectrode distance of a candle "And"

Spark plugs have a carving in diameter of 14 mm. Manufacturers recommend candles of certain type, however it is possible to use suitable candles with corresponding калильным number of other manufacturers. The distance between electrodes of candles makes 0.7 - 0.8 mm and are measured in a place (), shown on иллюстр.
Spark plugs should be cleared пескоструйным by the device through each 10 000 km. Thus to establish the corresponding interelectrode distance. At distance adjustment never to turn in an average electrode as the porcelain insulator can burst.
Before вывинчиванием candles to check up, that in niches of candles there were no extraneous subjects. Got to apertures of candles of a washer, bolts or stones will destroy valves, saddles of valves or a head of cylinders at the first start of the engine.
On appearance of a candle it is possible to draw a conclusion on work of candles, carburettor adjustment, a condition of a mix and an engine condition (pistons, piston rings etc.) (photographic inserts see).

Coal adjournment

Symptoms: soot Presence specifies in reenrichment of a toplivno-air mix or weak intensity of a spark. Causes ignition admissions, complicates start and leads to instability of work of the engine.
Recommendations: whether Check up the air cleaner is hammered, whether fuel level in поплавковой to the chamber is not too high, whether is jammed air заслонка and whether contacts are not too worn out. Try to use candles with longer insulator that raises resistibility to pollution.

Замасливание

Symptoms: zamaslivanie candles it is caused by deterioration маслоотражательных caps. Oil gets to the combustion chamber through worn out directing valves or piston rings. Causes ignition admissions, complicates start and leads to instability of work of the engine.
Recommendations: Make a mechanical recovery work and replace candles.

Overheat

Symptoms: the Porous, white insulator, erosion of electrodes and absence of any adjournment. Leads to reduction of service life of a candle.
Recommendations: whether Check up corresponds to requirements of Specifications калильное number of the established candles, whether the corner of an advancing of ignition is correctly exposed, whether too poor toplivno-air mix moves, whether there are no leaks of vacuum of the inlet pipeline and whether valves are jammed. Check up as level of a cooler and whether the radiator is corked.

Too early ignition

Symptoms: Electrodes are melted off. The insulator has white colour, but can be and is polluted owing to admissions of ignition or hit in chambers of combustion of extraneous particles. Can lead to an engine exit out of operation.
Recommendations: Check up калильное number of the established candles, a corner of an advancing of ignition, quality of a mix (whether it is not too impoverished), whether the system of cooling is corked and whether the greasing system normally functions.

Electrospending luster

Symptoms: the Insulator has yellowish colour and the polished kind. Speaks about sudden rise in temperature in combustion chambers at sharp acceleration. Usual adjournment are thus melted off, taking a form of a varnish covering. Leads to ignition admissions at high speeds of movement.
Recommendations: Replace candles (colder, at preservation of a manner of driving).

Short circuit of electrodes

Symptoms: the Waste of products of combustion gets to interelectrode space. Firm adjournment accumulate, forming a crosspiece between electrodes. Leads to ignition refusal in the cylinder.
Recommendations: Remove adjournment from interelectrode space.

Candle normal state

Symptoms: Gray-brown colour and easy deterioration of electrodes. The kalilnoe number of candles corresponds to type of the engine and its general condition.
Recommendations: At replacement of candles establish candles of the same type.

Пеплообразование

Symptoms: Soft brownish colour of adjournment on one or both electrodes of a candle. A source of their formation are applied additives to oil and-or fuel. Excessive accumulation can lead to isolation of electrodes and cause admissions of ignition and astable work of the engine at acceleration.
Recommendations: At fast accumulation of adjournment change маслоотражательные caps that will prevent oil hit in combustion chambers. Try to replace fuel mark.

Deterioration

Symptoms: the Rounding off of electrodes with a small congestion of adjournment on the working end. Colour normal. Leads to difficulty of start of the engine in cold damp weather and to increase of the expense of fuel.
Recommendations: Change candles on new the same type.

Detonation

Symptoms: Insulators can appear chopped off or треснутыми. The inaccurate technics of adjustment of a candle backlash can result In insulator damage also. Can lead to damage of pistons.

Забрызгивание

Symptoms: After admissions of ignition during a long time interval of adjournment can be loosened at preservation of working temperature in the combustion chamber. At high speeds of adjournment in flakes come off the piston and stick to a hot insulator, causing ignition admissions.
Recommendations: Replace candles or smooth out and establish into place the old.

Mechanical damages

Symptoms: Can be caused hit of extraneous materials in the chamber of combustion or arise at piston blow about too long candle. Lead to refusal of functioning of the cylinder and to piston damage.
Recommendations: Remove from the engine extraneous particles and-or replace
As service life of candles usually makes 15 000 km, it is enough to clear of them through each 8000 km of run. At ввинчивании candles to watch, that they have not been drawn, as the sealing washer can be damaged. The inhaling moment should not to be exceeded.
For preservation of capacity of the engine of a candle it is necessary to replace not less often, than once in 2 years.

Instructions

Spark plugs of the new engine X 22 XE (volume 2.2) demand replacement each 4 years or 60000 km of run.
