About 100 years ago, company Bosch. was presented candle ignition. Laying non-losant time their started everywhere apply on everything peace, for ignition mixes fuel and air v engines.

They work v talker conditions, constantly exposed exposure high temperature (approx. 1000 degrees) and high voltage (before 40 thousand. volt).

Device and principle work candles ignition

Candles ignition arranged simply, in fact they consist from explorer v center, metal corps to whom weldaren side electrode, and isolator. Despite on simplicity his devices, they play one from the most important roles v work engine car. Their duty is to ignite the combustible mixture, in all conditions and at any load on them.

V moment, when piston v tact compression comes v upper dead point, emits electric spark, ignifiers mixture from air and fuel. Spark arises between central and side electrodes. For her occurrence, necessary voltage not less 20 thousand. volt. Per his receipt replies system ignition, she converts 12 volt obtained with battery car, v 25—35 thousand volt necessary for normal work candles. Moment, when must serve high voltage determined sensor regulations crankshaft vala.

There are three main types of spark plugs which are now widely used. They differ from each other and design features of which are made of metal.

The main types of spark plugs:

• two-electrode;
• multi-electrode;
• Candles made of precious metals.

Let's consider more in detail the first two types.

two-electrode and multielectrode candles ignition

classical candles ignition counts two-electrode. From name maybe become clear, what this candle it has two electrode one central, second side. Between which arises spark.

multielectrode this is upgraded classical candle. She it has so same one central electrode, a here lateral electrodes already several maybe to be two, three and more. Per check increase their numbers work candles stabilized and her term operating increases. Work engine at it is it is becoming more smooth. Candles this type also allow develop his great power, a his environmental options becoming better.

cold and hot candles ignition

Candles ignition differ not only on type, a also on his features and selected individually v dependencies from design engine. By features they divided three different groups cold, average and hot.
What would understand, what this is means and why they need, necessary figure out what that « glow number» and « glow ignition».

• glow number call value, display time, across that candle reaches glow ignition. How above w. hERE glow number, top smaller she will heat.
• glow ignition call negative the effect, when ignition flammable mixes v engine occurs not from candles ignition, a from warmed up element engine, more often total this is it happens itself candle ignition. This the effect arises if v car installed candle with unsuitable heat rating number.

Conditions work candles ignition v summer and winter time differ, therefore v ideally better have v complete candles for different of time of the year.

For example, v hot weather, at riding on big velocity candle with low heat rating number, quickly will lead to glow the healing. What results to loss capacities. V this situation spark necessary replace on more « cold»
V feedback situation if at low temperature for example v traffic, occurs easing spark. V cold weather any problems with launch engine. V case occurrence this problems necessary put more « fervent» spark.

On choice also affect and the size engine, what he more top « colder» should to be candle.
groups candles on glow number (Russian marking):

• V « fervent» group includes candles propertied glow number from 11 before 14.
• V « secondary» group includes candles having glow number from 17 before 19.
• V « cold» group includes candles having glow number from 20 before 26.

V diesel engines very often used glow ignition, then there is self-ignition, from tense candles, what eases running engine at low temperatures.

Prechamber spark plug

Not so long ago, another type of candles appeared on the market, so call the forkamer or otherwise plasma. Manufacturers of such candles promise a significant increase in engine power, almost eternal work and many other advantages and advantages over other candles. But as practice shows, most of these promises do not come true, the engine power compared to classic candles does not increase. In some cases, on small speed, the engine begins to "told", and at high candles they can begin melting. The only plus in fact is the amount of harmful substances in the exhaust gases, it really decreases.

This technology may have a big future, but today it is still enough "raw." If you are not a lover of experiments with your car, and Wang needs his stable work without surprises, it is better to immediately refuse their acquisition.

Fault candles ignition, signs and causes

Without workers candles ignition it is becoming impossible normal exploitation car.
Consider signs fault candles, which requiring urgent interventions driver:

• V some increases consumption fuel;
• Occurs the fall capacities and set turns v work power aggregate;
• Heavy running engine;
• Increases concentration Co. v exhaust gas;
• Felt cutting car in time movement;
• Not pleasant noise infantry from engine on butt go.

Causes same such phenomena how valid simple:

• Candle simply developed mine resource;
• Melting electrodes or their corrosion;

• Not right mathed candle;
• Pollution (deposits, nagar., butter or fuel on electrodes);
• Damage or pollution isolator.

V case occurrence similar faults, follow urgently accept measures. V nasty case maybe occur detonation engine, what fully remove his from building.

When change candles ignition on auto

Faulty spark plugs can lead to heavy consequences, thus how damage fuel systems and engine, a this is threaters where more large costs. From their timely replace depends preservation power aggregate car.

When same all—taki change candles ignition?  We try figure out v it is question. Such signs like:

• Signs wear samoa candles, they noticeable naked eye. it melting, skoli. and corrosion.
• Running at riding;
• Problems with launch;
• The fall capacities and traction engine;
• Increased flow fuel;
• Regular education nagara on candle everyone 20—30 kilometers).

May indicate the need to replace candles.
On average, the candles should be changed every25—30 thousand mileage car.

Nagar. on candle, analysis work candles ignition

Candles are installed in the head of the cylinder block, their electrodes are constantly in the combustion chamber where the temperature can reach three thousand degrees. Despite its small sizes, when the engine is running, they are constantly under the influence of high temperatures and high voltage electric current. We are subjected to colossal pressure drops, vibrations, the effects of various chemical substances in fuel.

There are the following reasons education nagara on ignition candles electrodes:

• Candle not right motorized on glow number (too much cold);
• Problems v adjustments carburetor(mixture enroll too much realified);
• Not right adjusted ignition (previously);
• Sticky high-voltage wires or insulator;
• Installed wrong gap between central and side electrodes.

• As a result education nagara on candle:
• Reduced power engine and worsen his running,
• In sprouter consumption fuel,
• Occurs destabilization work on butt go,
• Increases ejection exhaust gas.

The ignition candle is exposed to a large number of negative effects and successfully works with such loads.

rules care per candles ignition

Normal color candles counts from light—gray before light—brown. Their necessary periodically clean and check out gapa between electrodes. N. a car located v permanent operating this is necessary make everyone 10 thousand kilometers. If automobile v year passes smaller 20 thousand kilometers, then cleaning and check gap necessary conduct two times v year, recommended this is make v end spring and autumn.
In time cleaning candles not recommended enjoy sharp items, so how this is maybe lead to damage and education scratch on insulator. Well suitable for cleaning, thin metal wire brush.
The ideal way to clean the candle is considered:

• Wash candles v gasoline;
• Dry out;
• On easy fire boil v 20 percentage acetic acid 20—30 minutes;
• After of this with help kapronova puppies clear and wash their v water.

Attention! This method necessary use on open air or v room having very good ventilation, so how during boiling stand out caustic couple. vinegar.

How select right and self best candles ignition

At select candles ignition v first queue follow repel from sizes and glow numbers. WITH dimensions difficulties not w. whom arise not must. Kalil number same selected v dependencies from of time of the year and operating car.
So, for example, for lovers fAST ride glow number must to be above, to prevent overheat, and hence, the effect glow ignition. At calm riding candles take away with little heat rating number.
V ideal better total explore instruction car, v her specified what kind candles suitable for this type engine.

On today's day best candles ignition on right consider candles from precious metals (platinum, silver, iridium and t.d..). Per these candles certainly have to pay improving amount, but benefits, which they give not less improverable:

• Huge term operating;
• Good self-cleaning;
• Significant raising environmental indicators;
• Increase capacities;
• Saving (how would this is paradoxial not sounded, at their price).

Such candles reduce consumption fuel, at regular operating car able pay off total per couple months.

At select candles from two-electrode and multielectrode choice definite better do v favor second, their options above first, a price not so just and strongly they differ. If same you all—taki decided buy candles from precious metal, then here better not save, and take quality candles from famous manufacturer, after all how known « stingy platitis twice».
