How to cut ceramics on a spark plug. “Promising” virtues

Why drill a hole in the spark plugs

Folk “craftsmen” claim that by drilling a hole in the side electrode of the spark plug, you can significantly improve sparking.

Increase engine power and reduce fuel consumption are two main goals that pursue supporters of tuning of their own cars. over, to achieve the tasks, of course, I want to with minimal cash costs. According to the numerous statements of the people’s “craftsmen”, you can simply worship the hole in the side electrode of the spark plug. A reasonable question arises, why such promising “know-how” still has not used the leading manufacturers of automobile accessories. Let’s try to figure out whether it is worth drilling the factory products, and immediately note that all the “advantages” described below with the candles modernized by their own hands, to put it mildly, are doubtful, but the negative consequences are very obvious. Therefore, remember, if you decide to conduct the experiment described below, you will conduct it exclusively “at your own peril and risk”.

The essence of the budget refinement of standard candles

The work algorithm is quite simple:

• Pour the standard spark plug in a vice.
• In the cartridge of the electric screwdriver, we install the drill.
• We drill a hole in the lateral petal (strictly opposite the central electrode).

On a note! Some “craftsmen” “promise” an even greater increase in the intensity of sparking, if you hide part of the side electrode and twist its edges. In this case, the hole must be moved to the side, as shown in the drawing below.

For the manufacture of “tuning” spark plugs, you will need the following tools:

Trouble. Changed candles, crushed a ceramic insulator, fragments got inside 🙁

I decided to change candles in Jim. I bought a domestic key, he didn’t get there (by the way, the 16 Satavskaya head is also for some reason), I had to sharpen it. began to unscrew, and the key is some kind of bad, as a result I crushed the insulator on all candles!! pulled out of the antenna with bilateral tape, everything that is smoothed. pulled out. On the advice, he took off all the candles, twisted the starter (Benz smells replaced), according to the theory, it was supposed to throw something out of there. He looked there. The wreckage is lying. Again the procedure with antenna and tape. I scrolled again, look, purely. put candles, conquest, will not start. Twisted-cereal, started, at first unstable, then he picked up, waited, the engine earned evenly, there were no extraneous sounds. Satisfied, I drank the beer. I am conquer this morning, I’m going to the gas station. And here on you! Glake. At first I did not understand, I thought the wheel lowered (the steering wheel became without a hydrchic), I am going to myself, I turn on the speed, gas. In short, I started, I go further if the turnover is more than 1,500 go normally if less than 1000 stalls. and further! Orange light bulb in the form of an engine caught fire. I hope that Benz is over because it is not in the car at all. but the light bulbs scares what kind of trouble is? There is no manual, in which cases this light is generally light? Help people!!

I wrote on our Yakut Forum. The guys have a fantasy work well that they just did not write.

P.S. And tomorrow I was going to go to the country house, eat meat, drink beer. I sob off a shame!

Answer: trouble. Changed candles, crushed a ceramic insulator, the debris got inside:

Do not grieve, comrade! Now the “fathers” will pull up. Everything will be resolved. From myself: I think that it was necessary to remove the cylinder block cover and clean everything there (I am an engineer, but it is bad in the cars myself. ). And now you need to read the error (the check is on). Saughty by searching on the topic “Error” “Light bulb” “check” well, like that. You will start to look. You will find there.

Advantages of independent refinement

The first method of tuning car supposits is to shorten the electrode, as a result of which its central part does not overlap with lateral, leaving the advantage.

The result of such a refinement should be the appearance of the possibility of regulating the clearance, followed by an increase in the working front of the spark, supposedly ensuring the flame directly into the combustion chamber.

The second technique implies the bend of the electrode in the external direction, which provides an increase in the clearance, however, it should be acted in this case with extreme caution, remembering how easy it is to damage the candle, which is fraught with its complete failure.

As for the advantages of independent refinement, according to forecasts, they are to improve the efficiency of ignition of the fuel mixture. This ensures a more full charge of charge and a decrease in the dependence of these indicators on the intensity of education on the candles of sparks.

So, the enhanced spark provides the fire of any mixture, even if it has the poorest composition. And if you manage to achieve such a result, then gasoline will burn more productively, increasing the power of the internal combustion engine without the slightest damage for the fuel consumption and, even vice versa, leading to its reduction.

It is worth noting that over time, this experience decided to adopt the Samara Design Bureau Nitron, which introduced the already finished modified suppositories of Dudyshev, during the development of which the principle of the nozzle of Laval was allegedly used.

However, those who managed to test this tuned product in practice, motorists noted that it is clearly inferior to homework, bypassing customers in a tidy sum, which vary in the range from 1 to 1.5 thousand. rubles (for comparison, it is worth recalling that a set of candles of Japanese production costs no more than 900, demonstrating a much more effective work).

What can be led to drill the hole

Correctly carried out tuning of classic spark plugs can add 5-6 horsepower to the motor, improving not only the quality of its launch, but also the dynamic characteristics. However, the risks of such modernization are often completely unjustified.

And above all, we are talking about the potential damage to the working element, since when drilling the holes of the electrodes, the walls of this hole inevitably become thinner, which is fraught with accelerated burning.

But this is not the worst, because a burnt element can fall into the cylinder, causing much greater damage in the form:

• failure of its rings;
• the formation of the so.called bully on the walls;
• serious motor breakdowns, followed by a major overhaul.

Do not forget that the candle overheating formed during the burning of the drilled walls is fraught with the appearance of a potassium ignition, also not in the best way affecting the work of the internal combustion engine. Simply put, the game is not worth the candle, in the direct and figurative meaning of this expression.

Subsequent stages of manufacture

After that, it is required to make a metal adapter. It is necessary when the ceramic part of the candle is used for the nozzle along with the threaded part made of metal. On one side of the adapter will be the most ordinary external plumbing thread, which is screwed into the shut.off valve. And on the other side there will be an internal thread where a candle with a remote electrode is screwed, which will work like a nozzle. The manufacture of an adapter does not require any special skills, but in general, it should be carried out by a professional turner on machines with the functions of thread cutting.

After that, the ceramic part of the candle with the extension at the end and the puck made of soft metal is clamped by the simplest plumbing nut. Next, you will need to screw the candle thread into the adapter, and screw the second tip of the adapter into a shut.off valve. At the same time, sealing using sealants or FUM tapes is optional.

In general, there are no requirements for tightness here. The pressure is restrained by a locking tap, which is located in front of the sandblasting nozzle located on the tip. With an open tap, the pressure is dumped through the hole of the nozzle of the gun. But if the nozzle closes with particles of an abrasive, then pressure will begin to form inside it, similar to what is present inside the compressor.

For this reason, complete tightness is not so much important as the strength is important. But still the nozzle should sit firmly.

Examination

Now a few words should be said directly about the verification of the finished device. At the first work of a home.made nozzle, it may turn out that it does not work or operates incorrectly. In this case, the first thing to check is the size of the hole. Perhaps it is very small. Or another option. the inappropriate abrasive is used. It can be either too large-grained or too moist, which is why it simply does not go into the nozzle.

It should be said that when clogging the nozzle, pressure grows in it. If ceramics received damage when disassembling a candle, then this may cause a part of the part.

Most often, masters use home.made nozzles with a diameter of 2 to 4 millimeters. The abrasive must have certain technical characteristics. The quality of work of the device made can be evaluated by comparing it with the device, which was used earlier, or according to the result of work.

The performance and quality of the entire device will depend on this element. In powerful industrial.type plants, nozzles are usually used that were manufactured in factory conditions. Sometimes they have a very complex geometry inside. In a number of models, the internal hole at the beginning and at the end is expanded, and in the middle it seems to narrow.

This makes it possible to form an increased working pressure of the abrasive type powder at the output and at the same time allows for its free passage without any congestion. On small devices, you can easily use homemade details. Typically, one homemade nozzle from a car candle can work up to 50 hours.

How to make a nozzle from the spark plug for a sandblasting apparatus, watch in the video below.

How to finalize with your own hands

The refinement of the spark plugs is not a difficult procedure, so even novice motorists will cope with it. In order to ensure a more effective level of operation of this element of the ignition system, first it is necessary to reduce the size of the side electrode (during this procedure it is necessary to carefully monitor that the lateral electrode does not overlap the central one), and then adjust the clearance. The procedure for independent refinement is performed in several stages:

• First, a candle from a car that has worked out its resource is being dismantled (if desired, you can use a new candle).
• Applying a special marking using an ordinary marker, according to which it is necessary to shorten the length of the electrode. The mark is applied on the side of the electrode. Instead of using a marker, on an electrode as a mark, you can carefully make a small notch.
• Then you need to wrap the finished element of the ignition system with a piece of rubber and squeeze it in a vice. It is best to use a vice that is made of rubber. In order not to damage the consumable (candle), Teska cannot be tightened hard.
• Using a grinding machine and a cutting circle, cut off the excess length of the side electrode. It should be noted that the resulting place of the cut should be even, without any irregularities or bevels.
• Using an ordinary suprafil, to clean up the cut site, eliminate all the irregularities and a backbone. At the site of the cut after the finish processing, there should be no burrs and other defects.
• At the final stage, it is necessary to set the gap of the desired value. The size of the clearance is determined taking into account the type, as well as the engine model that is equipped with a vehicle. In this case, it is recommended to get acquainted with technical information on various forums and specialized Internet resources.

After the completion of work on refinement of candles, they must be re.installed on the internal combustion engine and try to make a trial start. In this case, the engine starting should be more lightweight and smooth. In addition, you can first check the modified device using a simple home.made stand. To make such a stand, a coil and a trambler are needed. Thanks to its use, you can conduct a simple ordinary test for the appearance of a spark.

Why is you need to modify the spark plugs

To begin with, the owners of old gasoline cars, mainly of carburetor, should finalize new spark plugs for good savings and power increase. As a rule, it is on such a metering system that the issue of gasoline consumption is the most acute.

In parallel with this, revision can positively affect the injector. At the same time, high.tech modern candles with an increased service life (Platinum, Irididia) should not be finalized. It turns out that changes and refinements are most relevant only in relation to ordinary candles.Now let’s take a look at what the practical benefit of improving candles.

• First of all, the ease of starting and, as a result, less risk of filling the candles. This is especially true in winter, when the fuel in the cold motor evaporates worse, the battery charge drops naturally, the oil gets in and the starter is weakerly twisting the engine.
• Another advantage that the “tuning” of the spark plugs promises is stable operation of the internal combustion engine in different modes (especially at maximum loads and high speeds) even when taking into account the composition of the fuel-air mixture will not be optimal, that is, the working mixture is too impaired Or enriched.
• Note that in high pressure conditions on modified candles, a lower effect is on a spark, which simply blows off on a regular candle. As a result of the power unit, not only starts well, but also burns fuel charge more fully, giving more power. Due to this, fuel consumption is reduced and savings are obtained.

Do.it.yourself

Modernization is based on the task of bringing simple candles closer to a number of parameters to the so.called sporting spark plugs. Such products are offered by many well.known manufacturers, while they cost significantly more.

Sports suppositories allow you to increase the power and achieve a reduction in expenses, the declared service life of such elements is 70-90 thousand. km. run. However, in practice, the effectiveness of their work is reduced, on average, after 15 thousand. km, and all the declared period of such candles do not nurse at all. Given the high cost, buy these elements every 30-35 thousand. km. It turns out an invoice.

We also recommend reading an article about which candles are better, iridium or platinum. From this article you will learn about what the main differences, advantages and disadvantages of these types of spark plugs are.

It is for this reason that many drivers do not seek to immediately change the set of candles, since there are ways to extend the resource of existing. The best way to solve the problem is the refinement of ordinary or sports candles of ignition.

The procedure is not difficult, so even beginners will cope:

• To do the work of candles as effective as possible, you need to shorten the side electrode;
• The next step will be the correct adjustment of the gap on the candle;

Now let’s understand more. As for the first point, shortening must be performed so that the central electrode is not blocked by the side electrode.

The whole process looks as follows:

• The spent candles are removed from the engine or prepared in advance (you can work with new elements);
• Further, using a marker or in another way (for example, a notch is made), a special mark is applied on the lateral electrode, which will indicate what length you need to shorten the electrode.
• Further, the candle is neatly clamped in a vice (preferably with rubber “lips”.It is important not to pull the vice so as not to damage the element.
• After that, you need to take a grinding machine, put a cutting disk;
• With the help of the tool, the lateral electrode should be shortened. It is important to ensure that the cut is even, without a bevel.
• Then the cut place is cleaned with a file, the zabins are removed, the edges are aligned, burrs and other defects are removed.
• Now you can start installing the right gap. The value will depend on the type and the ICE model. In this case, it is best to use the manual, get the necessary information on specialized automobile forums, etc.D.
• Shortening the electrode and setting the gap on the spark plugs must be done with each candle, while be sure to observe the maximum possible accuracy (how much is cut off from the electrode and which gap is exhibited)
• After installing the modified candles on the engine, it is necessary to make a trial launch. As a rule, the launch should be more lightweight compared to conventional candles.
• Next, you can make a trip by evaluating the stability of the work and improving the receipt of the ICE, as well as the best traction at high speeds.

You can also clearly evaluate the work of candles. To do this, right in the garage, it will be enough to make a stand for checking. For manufacture, you must have a tunmer, coil and power source.

Next, a regular test for a spark is made, which will demonstrate an increase in sparking, a change in the color of the spark to a bright blue-red, etc.D. It is optimal to check in the form of comparative analysis, that is, compare the spark, its power and color before the start of work (on regular candles) and after (on modernized).

If we talk about the refinement itself, the simple manipulations described above allow you to expand and significantly increase the front of an electric spark. In other words, the spark after removal of the part of the electrode was not clamped between the two electrodes (lateral and central), but immediately directed to the combustion chamber.

As a result, the efficiency of ignition of the fuel and air mixture in the motor cylinders improves, the subsequent combustion of the charge becomes more full. The dependence of ignition on the quality and intensity of sparking on the candle with respect to the composition of the working mixture is also reduced.

In other words, a more powerful spark is easier to ignite a rich or poor mixture to one degree or another, which positively affects the overall operation of the engine under loads and in other modes. If the mixture is better ignited by the spark, then the front of the flame spreads more evenly and freely, gasoline burns fully in the cylinders, the power increases, the fuel consumption decreases.

The use of the tool

To properly use a home.made tile cutter, they undertake the following:

• A level, rule, iron line or other strong even tool is applied to the line of the future incision on the tiles;
• They clamp the level with one hand, and the second at this time is held by the tile cutter and carried out in a sharp part along the line in the direction of themselves;
• cut a fishing line for a trimmer with strong pressure to leave a noticeable scratch deeper;
• if necessary, repeat the drawing of another 1-2 times;
• Gently break the tile along the scratch, hitting it slightly on the hammer (the latter is wrapped in advance with rags);
• If the fishing line for the trimmer is deep enough, the tiles will split perfectly evenly, while holding it back to the hammer.

Of course, such a tile cutter is unlikely to cut a very thick material or porcelain tile.

The tool is not too well suitable for embossed raw materials, since it usually has a very strong icing. For such a coating, you will have to buy a factory tile.

In other situations, it is quite possible to save and make all the work without unnecessary costs with the help of a “home” tool.

Masters recommend making nozzles from imported candles “Champion” and “BRICS” with a long internal insulator. It is difficult to extract the core from domestic candles. It has extensions and small anchors for a strong connection with ceramics. Therefore, when trying to pull out a metal core, the insulator often pricks. Such a candle is more reliable for its main application, but is worse for remaking.

Materials

In addition to a candle, you will need cutting discs for an angle grinding machine (corner grinder): for metal and diamond on concrete for cutting ceramics.

Tools

• Vise in which they clamp the candle.
• Angle.grinding machine (angular grinder).
• Passatigi.
• In some cases, a gas burner may be required.

How to make yourself?

In most homemade and factory household apparatuses, the nozzle is mounted on a shut.off crane, with which the flux of the abrasive is opened and closed during operation. Fastening systems may differ, and unique solutions are found in homemade devices. Therefore, the shape and size of the manufactured nozzle may differ. If the nozzle is attached to the clamping flange, a small piece of the insulator with an extension at the end is simply cut off from the candle.

• The candle is clamped in a vice.
• Using the cutting circle on the metal, the thread is cut off from the metal part. The cut part is removed, opening the inside of the ceramic insulator.
• The desired part of the ceramic insulator with an extension at the end is cut off with a diamond circle. Cut to the end. You can make a tuck and break off the fragment with pliers.
• The fragment is also tightened with the electrode by plots if the electrode has not been removed before.

A copper washer is put on the insulator, which rests on the expansion of candle ceramics. They put on a standard plumbing nut on top, which is wound on a flange and fixes the nozzle. There are options for self.lives when the thread of the candle itself is used (metal “skirt”).

In this case, a metal core is removed from the candle (electrode). Candle thread is not suitable for standard plumbing sizes and types of carvings of locking cranes. Therefore, it will be necessary to separately manufacture a metal adapter.

How to disassemble the spark plug?

Structurally, the candle is made as an unlimited element. To remove a metal core (electrode) from the ceramic part of the whole candle, the candle is heated by a gas burner. Metal with severe heating (reddened) expands more than ceramics and core partially extended from the whole candle itself.

After cooling it can be pulled out by the pliers. If not the entire candle is required for the nozzles, but only a fragment of a ceramic insulator, it is not necessary to remove the electrode entirely. A tied fragment of ceramics is pulled together by plots from the electrode of a candle clamped in a vice.

Making an adapter on a lathe

A metal adapter is required when the ceramic part of the candle is used for the nozzle along with the metal threaded part. On one side of the adapter, a standard plumbing external carving, which is screwed into a shut.off crane.

On the other side, the inner thread, into which they screw a candle with a remote electrode, which will work as a nozzle. The manufacture of an adapter does not require particularly high qualifications, but is performed by a professional turner on machines with the functions of thread cutting.

Assembly

A ceramic fragment of a candle with an extension at the end and a puck of soft metal is clamped by a standard plumbing nut. The option using a candle thread is screwed into the adapter, the second end of the adapter is screwed into a shut.off valve.

There are no special requirements for tightness here. The pressure is restrained by the shut.off valve in front of the nozzle. With open tap, the pressure is discharged through the nozzle hole. But if the nozzle is clogged with particles of an abrasive, the same high pressure is created inside it as in the compressor. Therefore, the complete tightness of the connection is not as important as its strength. Thread or flange seal fum with tape or sealants is optional. But the nozzle should hold on quite firmly.

Saving gasoline from cutting candles electrodes

On the Internet you can find many ways to save fuel. But especially often advised to feed the side electrodes of the spark plugs. So I want to do this to save gasoline.

The answer to this question is based on the sensations of drivers. I put the filled candles, and it seems that the engine began to work better, and the car drove faster. But first you need to figure out whether this effect is possible.

To find out, you need to exercise control on devices and compare with ordinary candles. But where did this topic come from and why do such a finalization?

When a spark appears on the candle, the combustible mixture is ignited, and the flame spreads on. The lateral electrode at the initial stage of combustion blocks the path of flame. If there was no electrode on the way, then ignition would have occurred much faster.

If the side electrode is cut, then the spark changes the angle of inclination from vertical to inclined to the side. The flame changes its direction, which positively affects the operation of the motor. Many people write on the Web that they sawed the electrodes, put the candles, and the engine went even, it began to pull it better.

But none of them experienced anything at the stands, and did not watch the readings of the devices. It is necessary to compare the torque in the cylinders with old and changed candles, calculate the percentage of power.

To determine whether the engine starts better or worse, you need to measure the time starting the starter with different candles. But it is unlikely that anyone is standing with a stopwatch near the car, everything is done in sensations.

Only the gas analyzer can check the improvement of the ignition process and compare with the factory candles. This is the main device that can give proof whether the refinement of the electrodes is useful.

Experiment

I decided to check the difference in engine operation by the gas analyzer. First put ordinary factory candles. The motor warmed up, checked at idle speeds.

This is what happened on the gas analyzer screen.

Then he screwed the candles with changed filled electrodes. These are the testimony.

Data remained almost the same. The main characteristic is SN (the volume of unburned fuel). There are no differences, so modernization practically does not affect the work of the engines.

But the experiment was conducted on a normal engine and adjusted combustible mixture. It may be that a spark on a cut candle will better light the mixture. For example, if the mixture is too poor, then the spark will ignite it faster compared to the factory candle. Respectively, there will be fewer ignition passes, and the car will be better starting.

Then the gas analyzer can show a big difference. But for this you need to continue to experiment. Perhaps I will continue this work if you are interested in. Write about it, you need to continue or not, and why.
