    Another empty bastard unsubscribed. Now about the towbar.

    Well, they raised it... well done, now the cars will sell 3 times less.

    Has anyone calculated how much diesel exhaust contributes to air pollution? It seems that these standards were invented by lobbyists or they were simply taken from the outside world. Cars With diesel engines occupy a tiny fraction of heavy-duty vehicles, which are almost all diesel. But even gasoline engines, especially trucks and buses, the combustion of fuel often works in such a way that it is impossible to breathe near them.

    Cool. trick him and sell him for a high price)

    beautiful car, would buy

    Without sufficient grounds, directly provided for ONLY by federal law, the inspector can only check with the driver his ability to send an employee on a tour to Kathmandu!!!

    I wish our p. Vova would ride on it

    Option number 3 (for cars with a working hand brake): if a malfunction occurs in the working brake system on the move, we do everything listed above in the first case, + do not sharply raise the lever hand brake until you feel the car braking. (it is advisable not to use it on ice in winter or at the discretion of the driver)

    The author collected everything up to Kucha and... did not say anything significant except Eraz and Colchis. Two Moskvich cars were 21412 and 2141-01. They traveled more than 250,000.00 km and sold them. Major renovation engine 178,000.00 and 172,000.00 km. If there were similar products now (modern ones), I would take them. And to criticize everything - sorry...

    Lawyers are even bigger charlatans than the same sellers of leftist certificates. The difference is that they protect themselves in advance and get their money in any case, regardless of the result.

    @Russian, The wine is excellent, but unfortunately only what remains in Georgia itself, that is, for one’s own consumption. Because really high-quality wine of true Georgian brands is produced there in extremely limited quantities. Well, everything that is intended for us, Russians with average incomes, is mostly produced under the “MINASSALI” brand. And what is characteristic is that the Georgians themselves recognize this fact. Therefore, it is very sad, but in this country they are now producing excellent and 100% high-quality only complete Russophobia. It's a pity...

    The authorities are once again showing the Russians that they are slaves whom the authorities will milk to the grave, taking away everything they can!

    A new version, this is a new 2.5 or 3 liter diesel, a new manual transmission, new transmission... etc. And the bumper and ladder to the roof... these are easy tuning.

The spark plug in a car serves to ignite the gasoline-air mixture; due to the heat generated during fuel combustion, the working cycle in the cylinders occurs, and any automobile gasoline engine operates on this principle.

How modern engines work

Modern engines run on gasoline fuel with a high octane number, which means that more energy is released when gasoline is burned, the temperature in the combustion chamber with high-quality fuel is higher than with low-octane fuel.

From all of the above, the conclusion is that the spark plugs of modern cars are subject to strict requirements, since they operate in high temperatures under heavy loads.

The better the quality of these parts, the less often spark plugs need to be replaced.

For each specific brand of engine, its own spark plugs with certain parameters are developed, and universality, as such, is present here only conditionally.

Device

Despite the variety of spark plugs (SPS) on automotive market, they are all designed almost identically, and any of the candles consists of the following components:

  1. Central electrode;
  2. Side electrode;
  3. Ceramic insulator;
  4. Metal case with threads and edges for unscrewing with a key.

On the metal body, the spark plug has a seal in the form of a soft metal washer, and at the end of the central electrode there is a contact nut on which the tip of a high-voltage wire or a coil is placed if there are no high-voltage wires in the ignition system.

Types of candles

Modern spark plugs may have a different number of electrodes - in standard industrially produced spark plugs, there is most often only one side electrode.

For better spark formation and better combustion fuel mixture spark plugs with two, three and four side electrodes are used.

Multi-electrode SZs are most often installed on complex engines with a large number of cylinders and a high compression ratio.

SZ may have their own design features and differ from each other:

  • diameter and thread pitch;
  • length of the threaded part;
  • dimensions of key edges for turning out spark plugs;
  • electrode materials (platinum, iridium, copper);
  • protrusion of the central electrode;
  • general sizes (there are short and long candles).

The central electrode protruding above the insulator ensures stable engine operation - spark plugs with such electrodes do not cool down and remain clean and warm longer at low engine speeds, and do not overheat when the load increases.

There is a special type of candles for racing cars, which do not have a side electrode, and its role is played by the threaded body itself.

Due to the fact that sports cars have a very small combustion chamber, there is no room left for the side electrode, which is why the design has this form.

Based on the material of SZ electrodes, they are most often copper (chromium-nickel) and platinum.

The use of precious materials provides the parts with a longer service life, and the central electrode is thinner than usual.

A thin electrode helps reduce voltage in the ignition system, and at high temperatures the spark plug works more efficiently and with better output.

Replacing spark plugs

For each car model, the manufacturer provides a certain period after which the spark plugs should be replaced.

The regulations must be observed when performing Maintenance, additionally, at each maintenance, these parts are checked.

When do you need to change spark plugs?

But now there are a lot of different manufacturers on the market, so the service life of the parts is different, and the parts can last from 20 to 100 thousand km.

SZ must be replaced in the following cases:

  • the engine has become one or more cylinders do not work;
  • the side electrode is burnt or has become thinner than usual;
  • the insulator breaks through to the central electrode (in some cases the breakdown is visible in the dark when the engine is running);
  • the insulator at the base with the metal body of the spark plug has turned black;
  • The SZ have exhausted their allotted resources.

The condition of the spark plugs can tell a lot.

The job of replacing a spark plug is not difficult to perform, and many car owners perform this operation themselves.

It should be noted that there are engines where it is quite difficult to get to the SZ, and in such cases, car owners prefer to entrust the work to specialized car services.

There are also motorists who believe that any car repair should be done by experts in their craft, and besides, the cost of replacing spark plugs is usually low.

Replacing spark plugs using the example of Skoda cars

The nuances of replacing spark plugs on Skoda engines.

On gasoline engines volume 1.6 l Skoda Octavia or Skoda Fabia The frequency of replacing spark plugs is on average every 45 thousand km.

Spark plugs with electrodes made of precious metals last longer; for example, iridium ones can last 90-100 thousand km.

Replacing spark plugs in a Skoda is not an easy procedure, and some technicians remove the intake manifold to get to the spark plugs.

But this is not at all necessary, if you have the necessary tool and with some skill, replacing the SZ with a Skoda with a BFQ (BSE) model engine can be done as follows:


After the work is done, we install it in place high voltage wires first and second cylinder.

The first tip is installed by hand; to install the second, you should use round-nose pliers, and you should try to insert the tip as tightly as possible, pressing it into place.

The most difficult thing is to replace the spark plug of a Skoda Octavia with a 1.6 liter engine on the third cylinder.

First of all, it is difficult to remove the tip - you can try to move it away from the cylinder head from below with a long screwdriver, pushing it between the metal screen of the tip and the cylinder head.

After the tip is pulled out of place, we take it out through the top and move it to the side.

In order to unscrew the spark plug on the third cylinder, we insert the spark plug wrench from the top right side, and look at whether the spark plug fits into the hole in the cylinder head from below under the manifold.

We unscrew the spark plug in the same way as on the second cylinder, take a new spark plug and install it in place.

On the fourth cylinder, the tip is pulled out using pliers (round-nose pliers), and it is easier to get to the SZ here than on the second or third cylinder.

Spark plugs directly affect performance power unit. Engine consumption and power depend on correct functioning internal combustion. When replacing, safety precautions must be observed. The procedure is carried out on a cold engine.

Timing for replacing spark plugs

The manufacturer of the Skoda Fabia states that spark plugs must be changed every 30 thousand kilometers. The following types of spark plugs are suitable for Skoda:

  • VAG 101 905 601 F;
  • 5960 NGK ZFR6T-11G.

Location of spark plugs in Skoda Fabia

The engine in the Skoda Fabia is located longitudinally. This means that the auto candles are located in this way. The 1.2 liter engine has 3 spark plugs. Each of them has a coil. To understand their wear, you will need to unscrew and measure the gap between the electrodes. If the distance between the electrodes is more than 1.0 - 1.3 mm, then the spark plugs must be replaced.

The main reasons that may indicate the need to replace spark plugs:

  • Increased fuel consumption;
  • Characteristic sound and reduced thrust;
  • Exhaust gases in the form of smoke.

A faulty spark plug can be detected by examining it in detail. Are there black soot stains on the body and core? The reason is poor quality fuel. Solution: you need to change the gas station or type of fuel. The black color of the body of the spark plugs may also indicate that oil has entered the combustion chamber. Reason for hit lubricant— failure of valve guides, piston rings or seals.

Soot covered the electrodes? This is carbon deposits. The air-fuel mixture has entered the cylinders. It is necessary to check the performance of the carburetor, cleanliness air filter, operation of the air damper drive.

If oil gets into the cylinders, oil deposits may form on the housing, core or electrodes. Cause: piston rings or the valves are faulty. The oily surface prevents sparks.

Is the ignition angle not adjusted correctly? A white coating has formed on the spark plugs. Such deposits also form when low-quality fuel is ingested.

If such symptoms are detected in time, the situation can be corrected.

Preparing for replacement

Before starting the replacement procedure, you need to prepare.

Tools for replacing spark plugs in Skoda Fabia 1.4:

  • Screwdriver (slotted);
  • Spark plug wrench 16 mm;
  • Long rod;
  • New auto spark plugs.

Safety precautions

The basic safety rules when replacing spark plugs in the Skoda Fabia power unit are as follows:

  1. Carry out the procedure on a cold engine.
  2. Disconnect the negative terminal of the battery.
  3. Use special clothing and gloves.

The process of replacing spark plugs

Step-by-step instructions for replacing spark plugs on a Skoda Fabia:

  1. Open the hood.
  2. Remove the decorative engine cover.
  3. A view of the coils will open. Lift and unfasten the contact chips from the coils. To remove the coils, use a slotted screwdriver.
  4. Pull out the coils.
  5. Unscrew the spark plugs. Use a 16mm wrench.
  6. Install new spark plugs. Reassemble in reverse order.
  7. Replace the decorative cover of the power unit. Connect the negative terminal of the battery.

The process of replacing spark plugs in the Skoda Fabia is complete. The engine should return to normal operation.

Regular replacement of “consumables” such as air and fuel filter, spark plugs, provide your car's engine with stable and long-lasting operation. In this article we will look at replacing spark plugs on Skoda Fabia with 1.4, 1.6 and 2.0 liter engines. The process itself will not cause you any special problems, so you can handle it yourself, saving several hundred rubles.

When to change spark plugs on a Fabia

The manufacturer sets the replacement period for spark plugs - once every 30,000 km. However, it is worth noting that the replacement period depends primarily on the spark plugs used. For example, if you have iridium spark plugs installed, they must be replaced every 60,000 km. If you use iridium-platinum ones, their service life is up to 100,000 km.

How to determine that spark plugs need replacing

There are cases when the spark plugs have not yet reached their intended service life, and the car itself “talks” about the need to replace them. We advise you to check the candles if you exhibit the following symptoms:

  • Poor engine thrust
  • Weak speed gain
  • Increased fuel consumption

If the above signs are detected, we advise you to remove and inspect the spark plugs, and if necessary, replace them.

Which spark plugs to choose for replacement

Spark plugs for 1.4 MPI engine

Original spark plugs are installed from the factory. The cost of one candle is from 300 rubles. As analogues you can choose the following:

  • Bosch 0 242 236 530 price from 180 rub.
  • Brisk DOX15LE1 price is 100 rub.
  • Denso KJ20DR-M11 price from 200 rub.

You can also install more expensive iridium spark plugs, the service life of which, as we wrote above, is longer compared to simple spark plugs.

Spark plugs for 1.6 l engine

  • Bosch 0 242 236 565 price from 180 rub.
  • DENSO IK20L price from 600 rub.
  • Denso KJ20DR-M11 price from 180 rub.
  • BOSCH 0 242 240 659 price from 130 rub.

When choosing candles, check their authenticity. The most popular manufacturers are most often counterfeited, so we advise you to purchase spark plugs only from trusted sellers.

Replacing spark plugs for a Skoda Fabia with a 1.2 liter engine

To replace, we need a 16" spark plug wrench and a flat-head screwdriver.

Open the hood and use a screwdriver to pry up the plastic clips of the engine cover. Let's take it off.

Having pulled out the coil, insert a spark plug wrench into the well and unscrew the old spark plug. We install a new one and reassemble in the reverse order.

Replacing spark plugs on a 1.4 liter engine

The procedure for replacing spark plugs on a 1.4 liter engine is identical to the 1.2 engine.

Remove the plastic decorative engine cover.

Disconnect the plug from the ignition coils and, using a little force, pull the coil out of the well.

By using spark plug key unscrew the spark plugs and replace them.

We screw in the new spark plugs, place the ignition coils tightly on them, and connect the block.
