Spark plugs - the general description
Interelectrode distance of a candle "And"
Spark plugs have a carving in diameter of 14 mm. Producers recommend candles of a certain type, however it is possible to use suitable candles with the corresponding kalilny number of other producers. The distance between electrodes of candles makes 0.7 - 0.8 mm and are measured in a place (And), shown on иллюстр.
Spark plugs should be cleared by the peskostruyny 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 a vyvinchivaniye of candles to check, that in niches of candles there were no extraneous subjects. Got to openings 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, carburetor adjustment, a condition of a mix and an engine condition (pistons, piston rings etc.) (see photographic inserts).
Symptoms: Availability of soot indicates reenrichment of a fuel and air mix or weak intensity of a spark. Causes ignition admissions, complicates start and results in instability of operation of the engine.
Recommendations: Whether check the air purifier is hammered, whether fuel level in the poplavkovy chamber is not too high, whether the air zaslonka is jammed and whether contacts are not too worn-out. Try to use candles with longer insulator that increases resilience to pollution.
Symptoms: Zamaslivaniye of a candle is called by wear of maslootrazhatelny caps. Oil gets to the combustion chamber through worn-out directing valves or piston rings. Causes ignition admissions, complicates start and results in instability of operation of the engine.
Recommendations: Perform mechanical recovery works and replace candles.
Symptoms: Porous, white insulator, erosion of electrodes and absence of any deposits. Leads to reduction of service life of a candle.
Recommendations: Whether check there corresponds to requirements of Specifications kalilny number of the established candles, whether the corner of an advancing of ignition is correctly exposed, whether too poor fuel and air mix moves, whether there are no leakages of vacuum of the inlet pipeline and whether valves are jammed. Check as level of a cooler and whether the radiator is corked.
Too early ignition
Symptoms: Electrodes are melted off. The insulator has white color, but can be and is polluted owing to ignition or hit admissions in chambers of combustion of extraneous particles. Can lead to an engine exit out of operation.
Recommendations: Check kalilny number of the established candles, a corner of an advancing of ignition, quality of a mix (whether it is not too grown poor), whether the system of cooling is corked and whether the greasing system normally functions.
Symptoms: The insulator has yellowish color and the polished appearance. Speaks about sudden temperature increase in combustion chambers at sharp acceleration. Usual deposits 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: A waste of products of combustion gets to interelectrode space. Firm deposits accumulate, forming a crossing point between electrodes. Leads to ignition refusal in the cylinder.
Recommendations: Remove deposits from interelectrode space.
Normal state of a candle
Symptoms: Gray-brown color and easy wear of electrodes. Kalilnoye number of candles corresponds to type of the engine and its general condition.
Recommendations: At replacement of candles establish candles of the same type.
Symptoms: Soft brownish color of adjournment on one or both electrodes of a candle. A source of their education are applied additives to oil and/or fuel. Excessive accumulation can lead to isolation of electrodes and cause admissions of ignition and unstable operation of the engine at acceleration.
Recommendations: At fast accumulation of deposits change maslootrazhatelny caps that will prevent oil hit in combustion chambers. Try to replace fuel brand.
Symptoms: A rounding off of electrodes with a small congestion of deposits on the working end. Color normal. Leads to difficulty of start of the engine in cold damp weather and to fuel consumption increase.
Recommendations: Change candles on new the same type.
Symptoms: Insulators can appear chopped off or burst. Also inaccurate equipment of adjustment of a candle gap can lead to damage of an insulator. Can lead to damage of pistons.
Symptoms: After ignition admissions during a long period 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.
Symptoms: Can be caused by 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 a vvinchivaniye of candles to watch, that they were not drawn, as the sealing washer can be damaged. The moment of an inhaling should not be exceeded.
For preservation of engine capacity of a candle it is necessary to replace not less than once in 2 years.
Spark plugs of the new engine X 22 XE (volume of 2.2 l) demand replacement each 4 years or 60000 km of run.
