How to call the ignition coil

The ignition coil is designed to create high voltage, which is further used by a candle to form a spark. Therefore, its working work is necessary for the normal functioning of the ignition system. In fact, the coil is a small transformer, the primary winding of which comes with standard 12 V from the battery, and a voltage of several kV comes out. It is used in all ignition systems. Contact, contactless and electronic. The reasons for the failure of the coil are typical. As a rule, this is a wire break, insulation damage, mechanical deformation. Next, we will consider signs of malfunctions and methods of diagnosing the ignition coil.

The principle of operation of the ignition coil

As mentioned above, the ignition coil is an increase in voltage transformer, which converts the resulting voltage of 12 V into a voltage with a value of several kilovolts. Structurally, the coil consists of two windings. Primary and secondary (respectively, low and high voltage). However, depending on the type of coil of the winding and their location differs.

Let’s start the description with the simplest common coil. There is 100 on the primary winding. 150 turns. The winding is wound up with an insulated copper wire. Its ends are displayed to the coil body. The number of stoves of the high voltage winding is 30. 50 thousand (depending on the model). Naturally, the wire used here is much smaller diameter. The “minus” of the secondary winding is connected to the “minus” of the primary. And “plus” is connected to the output on the lid. Thus, the removal of the resulting high voltage is ensured.

To increase the magnetic field, windings are wound around a metal core. In some cases, to avoid overheating of the winding and core, poured with transformer oil (it not only cools the system, but also is an insulator).

Now let’s move on to the consideration of the individual ignition coil. There are also two windings, but the difference is their location. In particular, they are wound in the reverse order. The primary winding has a core of the internal type, and the secondary. The external type.

Individual ignition coils are installed in systems with electronic ignition. Therefore, their design is complicated. So, to cut off a significant current in the secondary winding, a diode is provided. Also, a feature of an individual coil is the fact that the resulting high voltage does not go to the distributor (as in classical systems), but directly to the spark plugs. This was made possible thanks to the design, which included an isolated case, rod and spring.

Another type of coil is two.Overall. She gives voltage at once by two cylinders. There are several of their varieties. As a rule, such coils are combined into one common block, which is essentially a four.Year.Old ignition coil.

Regardless of the type of ignition coil, their main technical parameter, which should be focused on during diagnosis is the resistance of the windings. In particular, the resistance of the primary winding is usually within 0.5. 3.5 Ohms, and secondary. 6. 15 kOhm (these values ​​may differ in different coils, so it is better to find reference information precisely by the model that is used in your car). Measurements are made using traditional devices. Multimeters or ohmmeters. If the resulting value is very different from the specified, then the probability that the reel is out of order is great.

You also need to keep abreast that each coil has various indicators:

Therefore, in order to understand how much the coil readings correspond to the norm, it is necessary to clarify the technical characteristics of your individual coil. This is especially useful for you if the spark is gone, since the ignition coil is one of the first elements of the system that are subject to verification.

Signs of malfunctions

There are several characteristic signs of a malfunction of the ignition coil. Among them:

  • The motor begins to “trigger”, and this problem is aggravated over time;
  • In the cold, the “Trith” motor until heated;
  • Interruptions in the operation of the engine in wet weather;
  • With a sharp press on the accelerator pedal, a failure is observed in the work of the motor.

With a faulty coil on cars with an ECU, the Check Engine icon is activated on the dashboard. However, the listed features may also indicate other malfunctions, in particular, with the spark plugs. But if at least one of them appears, you need to diagnose the coil (coils) of the ignition.

Causes of malfunctions

There are several reasons because of which the ignition coil fully or partially fails. Among them:

  • Mechanical damage. This can be banal aging, due to which the isolation is destroyed. There is also the likelihood of oil flow through the seals, which falls on the insulation or coil body and destroys them. Repair in this case is unlikely to be possible, so the best option would be a complete replacement of the node.
  • Contact connection damage. In warm weather, the reason for this may be moisture in the engine compartment. For example, during heavy rain, driving in deep puddles, car wash. In winter, it is likely to get into the coil of the composition, which sprinkle the surface of the road to combat ice.
  • Overheat. Individual coils are often susceptible to him. Due to overheating, the life of the ignition coils can significantly decrease. The overheating process is difficult to control, but try to use high.Quality coolant and make sure that the engine cooling system works normally.
  • Vibrations. They are especially harmful to individual ignition coils. Vibrations, as a rule, goes from the head of the cylinder block (GBC). To reduce the amount and amplitude of vibrations, make sure that the engine operates in normal mode (without detonation and with good pillows).

The ignition coils are quite reliable and durable nodes, and their failure is most often associated with aging and/or a breakdown of isolation. Next, consider methods for diagnosing coils.

How to check the ignition coil

There are two main methods with which you can independently check the performance of the ignition coil. We list them in order.

How to set ignition on a walk.Behind tractor?

The following signs will tell you about the need for urgent adjustment of the gap in the ignition system:

  • The need for frequent unsuccessful stretching of the starter cord;
  • A belated reaction of the engine of the walk.Behind tractor to manipulation with the starter;
  • The complete absence of launching the internal combustion engine agricultural load.

Each of these malfunctions suggests that the operator should be installed by the ignition of a motor block used in the farm. The correct procedure for this can be found in the operating instructions for existing equipment. However, the leadership is far from always at hand at the operator. In this case, the gap between the built.In ignition module and the flywheel can be set in the following sequence:

  • First, the operator must close the candle with a special square;
  • Then its case will need to be pressed to the head of the standard ICE cylinder;
  • Next, the candle must be crank up in the direction opposite from the hole provided in the end of the chrome cylinder;
  • After that, it is necessary to gently turn the crankshaft of the ICE of the walk.Behind tractor. For this, it is enough to pull the cord of the starting mechanism;
  • As a result of the actions performed between the built-in electrodes, a bright blue spark should slip. If this does not happen, then it is necessary to check the distance between Magneto and the starter of the walk.Behind tractor. It should be from 0.1 to 0.15 mm. In case of inconsistency of these requirements, the gap between the elements will need to be configured.

The ignition of the economic walk.Behind tract is adjusted by many experienced users by ear. For this, both contact and contactless magneto are suitable for this. To independently configure the system, you need:

  • Start the engine and slightly loosen the standard trimbler;
  • Slowly turn the breaker in each of the possible sides;
  • Achieve maximum revolutions of the factory engine and quickly fix the structure;
  • Listen and find the moment at which a spark instantly appears;
  • Turning the breaker, wait for a clear clicking sound;
  • Fix the standard fastener of the trambler.

In some cases, the strobe will help to adjust the existing gap correctly.

  • Heat the power unit of the walk.Behind tractor;
  • Connect the device to the electric power supply network of agricultural loads;
  • Install the sound sensor on a high.Voltage wire connected to one of the cylinders of the standard ICE;
  • Gently remove the vacuum tube and drown it out by any improvised tool;
  • To see where the light from the strobe will be directed. It must “look” towards the standard pulley;
  • Run the engine and leave it to work at idle;
  • Scroll the trambler;
  • As soon as the tags on the built.In pulley coincide with a mark located on the cover of the device used, to turn the nut of the factory interrupt to the end.

Each of these methods is suitable for adjusting both gasoline and diesel walk.Behind tract. The main thing in the process of independent setting is not to remove the coil and other elements of the ignition system. This can lead to a violation of the entire unit.

Oil in the engine

The manufacturer recommends the use of such well-known brands of motor oil for the walk-behind tractor-LUKOIL-SAE 10W30 API SF/CC standard, as well as Ravenol SAE 30 API CD/SF.

At temperatures above 4 degrees of heat, use thickened oil varieties (for example, 10W30 brands) will lead to an increased consumption of this type of fuel, therefore, in the cold season it is recommended to more often check the oil level in the engine, preventing a reduction in its mark below the norm.

Oil change is carried out after the one.Legged tractor has recently visited work until the engine has completely cooled down. It should be warm, but not hot. The remains of the oil are drained completely from the tank, after which the new one is added until the oil level reaches a special mark. The drain plug is then tightly twisted and wiped dry.

There is no spark on the walk.Behind tractor. Reasons and solution

Lack of sparks

This is one of the typical malfunctions of the ignition system of the walk.Behind tractor. The most common reasons for this are the formation of a pile on a spark plug or its breakdown. In this case, you should twist the candle and carefully inspect its lateral and central electrodes. If the spark plug is covered with a soil formed as a result of pouring the part by the fuel mixture, then the candle will be not enough alone. It will be necessary to check the tubes of the fuel system of the motor block for leaks. Examples of cases with highly planted fuel candle are clearly visible in the photo.

If a spark is gone, then in any case you will need to carefully clean the candle. To do this, it is best to heat it above the gas burner, and then scrape off the dried fuel from the surface. After cleaning the part on its upper part, the tip should be put on and bring the motor block to the body body. The candle must be held so that its electrode is about 1 millimeter from the engine housing. At the same time, try to launch a motoblock motor with the second hand.

If the candle is completely serviceable, then a spark is formed in its lower part, which will jump out and hit the motor body. If this does not happen, then you need to inspect the distance between the side and central electrodes. Between them should be placed a blade, and if it enters tightly between two electrodes, then the gap has the optimal dimensions. If the blade hangs, then you will need to knock on any hard object on the back of the central electrode. As a result of this, he shift, after which you need to try again to start the engine engine.

Self.Check of magneto for a walk.Behind tractor

Another important element of the ignition system of the walk.Behind tractor is magneto. In case of malfunction of the node, it also lends itself to a careful inspection for performance. Checking the Magneto Motobobok is quite simple. To do this, it is necessary to clean the candle from the carbar accumulated on its surface and make sure of its serviceability. Then a cap with a good drive is put on the candle. Further, the lower part of the candle must be brought to the Magneto body, and start rotating the flywheel located in the motor with your fingers.

If the spark in Magneto did not appear on the uniform tractor, then the element is out of order. In this case, it will be necessary to replace the magneto of the ignition system of the walk.Behind tractor in order to prevent wear of other unit mechanisms.

How to check the ignition coil on a walk.Behind tractor?

Check, and, if necessary, repair the ignition coil, follows the same principle as the Magneto Motobobok.

The following factors indicate the signs that the ignition coil of the walk.Behind tract is out of order:

  • Weak spark or its complete absence;
  • The presence of the smell of molten plastic in the area where the ignition coil is installed;
  • The appearance of crackling sound when trying to start a single tractor.

In any of these cases, you will need to carefully examine the ignition coil of the walk.Behind tractor. To do this, it is best to completely dismantle it. For this purpose, you should first unscrew the fasteners and remove the upper cover of the ignition system body. Then you need to turn off the high.Voltage wire and, gently prying the coil, extract it from the case. After that, you need to carefully examine the part on the presence of traces of melting. If black spots are visible on the coil, then most likely the current it created did not get to the candle, as a result of which the ignition reel itself succumbed to the voltage. Especially often, farmers are faced with this problem, in whose walk.Ashes, a contactless ignition is installed.

The reason that the current did not fall on the candle is poor contacts on a high.Voltage wire. In this case, the repair of the ignition of the walk.Behind tractor is reduced to cleaning the wires or their complete replacement. In the motoblocks where the electronic ignition system is installed, in case of breakdown, the wire is automatically turned off due to the presence of a special fuse. In agricultural machines with ignition systems of other types, disconnect the wire during breakdown manually.

Prevention of breakdowns of the ignition system of a walk.Behind tractor

In order to avoid the need to repair a motor block ignition system, you need to adhere to a number of simple rules. Their compliance will extend the deadlines for the use of the node and save the time and money of the owner of the equipment.

  • To exclude the use of a walk.Behind tract in raw weather, during frosts, as well as under the conditions of sudden changes in temperature and humidity;
  • Do not try to start the unit if there is a smell of molten plastic;
  • If necessary, install the plates on the uno.Based tractor that protect the parts of the ignition system from moisture from getting on them;
  • Change the candle at least once every 3 months. In the case of intensive use of a motor block, the frequency of replacement of the part can be increased;
  • Use high.Quality motor oil. The use of the inappropriate composition will lead to constant filling of the candle with a fuel mixture;
  • Regularly inspect the parts of the ignition system in order to exclude the slightest possibility of operating a walk.Behind tractor with ragged wires or other breakdowns;
  • Try not to give one.Time tractor with a hot engine with strong loads. This will lead to an accelerated wear of important components of the unit, including its ignition system.

Adhering to these simple rules, the owner of the walk.Behind tractor will increase the working resource of the ignition system and other important details and mechanisms of his unit.

All of the listed problems with the ignition system are typical of the production of Urals, Mole, Zubrov, Agro, Neva, Honda, Salute, MTZ and Cascade. The configuration and repair of the node is performed in the same manner for each of the listed agricultural units.

Peugeot 307 SW 1.6-16V 5dv. Universal, 110 l.C, 4AKPP, 2005. 2008.In Engine Trith

Engine touch. A definition, which should be understood as a failure in the operation of the internal combustion engine, when one or more cylinders do not work partially or completely. To say otherwise, the process of combustion of the fuel-air mixture in separate cylinders is disturbed, which causes unstable operation of the motor at idle, under load and in transition modes.

The engine touch is manifested in the form of enhanced vibrations of the power unit, the engine noticeably loses its power. Ignition passes may be observed, which are accompanied by strong claps in the exhaust system. The motor can touch both occasionally and constantly, only in idle or under load, on cold, hot, etc.P.

Further, we intend to answer the question of what the engine is tanks, as well as consider the main reasons why the motor begins to trumpet.

Why the motor begins to trigger the engine of engine is a violation of the combustion of the mixture in the cylinders, which is accompanied by a clear increase in vibration. Please note that the emergence of vibrations of the internal combustion engine is not necessarily a touch, since there are a number of other reasons why the engine vibrates greatly.

Engine Trith: the ignition of the fuel-air mixture is impaired

To check the candle is securely attached to the mass, then the caps are connected to them, after which one person twists the motor with a starter, and the other evaluates the power of the spark on the candles.

Motor Trinity: Air supply malfunctions

Deviations from the norm in the indications of an air bond or sensor of the throttle position leads to the fact that the engine begins to touch.

Low pressure in the fuel supply system is often the cause of touch. The next step will be a check of injector nozzles. This element has the ability to clog, as a result of which the throughput is reduced, the shape of the spray torch is disturbed, and t.D. Also, the failure of the nozzle itself should not be excluded.

Often this occurs in cases where the factory firmware changed when installing HBO or motor made software chip tuning. Unprofessional manipulations with fuel cards can lead to the ECU pouring fuel and floods the spark plugs.

Why is the ignition adjustment

In some cases, when the engine does not start, the ignition adjustment will be required. Of course, first you need to check the serviceability of a candle and a high.Voltage cable with a cap.

It is necessary to adjust the ignition on a two.Stroke engine in order to ensure timely ignition of fuel in the engine combustion chamber. Below is a scheme from which you can understand the principle of operation of the internal combustion engine.

The spark in the candle should appear at the time of compression of the fuel with a piston, when it does not reach the upper dead point (VMT) at least a little. Когда поршень проходит ВМТ, происходит возгорание топливной смеси, в результате чего поршень под действием энергии взрыва уходит вниз.

Therefore, if for some reason (mainly this is due to the shift of the flywheel to the shaft regarding its original position), the fuel fire occurs earlier than the piston passes the vehicle, then it returns back, and the crankshaft scrolls in the opposite direction. Such a movement can damage the starter knot, cut off the launch cord, etc.D. In this case, an early ignition of fuel occurs.

There may also be a later ignition on the trimmer: the piston after compression of the fuel, which does not ignite, goes down, and at that moment a spark appears. In this case, the engine will either not start or significantly lose power and will be poorly gaining momentum.

But such problems with early or late ignition on two.Stroke ICE are quite rare, since the flywheel with magnets is already established in the correct position, which is perfectly synchronized with the movement of the piston. In addition, the flywheel is fixed on the shaft using a key and nut. Therefore, the wrong installation of the part is excluded.

Basically, the ignition adjustment is to set the correct clearance between Magneto and the flywheel.

Modernization of the ignition system (MB-1) of the MROT motor-cultivator

Welcome all! I want to talk about the alteration of the mole ignition system, which allowed me to get rid of all the problems with the reliability of the ignition, and later greatly facilitated the engine factory. I have not yet met such refinement on the pages of this forum, and in other places too, and I hope that my work I did will come in handy.

About everything in order. I did the first alteration back in 2021. The message was simple. The main trouble of Magneto MB-1, in my modest opinion, is its miniature (as well as one flaw in the scheme). If the designers immediately followed the path, which is known along light motorcycles, they would have produced generator coils, an electronic circuit and ignition coil to different nodes, then the ignition would not have problems.

And here it turned out that both the generator coil is wound with a very thin wire, and the ignition coil is small, and most importantly-the electronic circuit is installed directly on the engine crankcase and easily heats up to 70-80. But the thyristor KU202N, used in Magneto is designed for a temperature of 75 degrees.

As a result, its frequent exits. After all, the same thyristor was used in many motorcycles and mopeds and nothing. He worked. The thin wire of the winding of the generator coil did not make it possible to develop a large current and put the accumulative capacitor of at least 1 μF, and how in motorcycles add the zener diode to cut off excess voltage.

In general, the idea was born for a long time to smash all three ignition elements. The coil immediately decided to use a car, having a multiple reserve. Then with a car large coil, the spark with the same diagram turned out at least three times more powerful. And then the car Toyota coil with a switch was just very successful.

The switch burned down and in his place I just installed my scheme. Attaching photo. I installed the coil on the plate on the steering wheel. High.Voltage wire standard, automobile. From his native MB-1 left only a generator coil and a sensor coil. Brought them out with wires, and for the sensor I decided to take a shielded.

So. What happened after the first alteration. Great reliability. Military thyristor T122-25-8, Diode bridge per 1000 volts, monumental ignition coil. There are no more weak places. The previous owner over 10 years of operation changed 6 MB-1. And here it will not break.

But there was a reason to sad. The scheme that perfectly worked on the table, giving such a spark that the elephant will stop, somewhat confused on the engine. The power of the spark fell. After a while, it became clear what was the matter. The reason for this is the generator coil. Very thin wire and many turns.

Only resistance to constant current about 3 kOhm. But during rotation, inductive resistance is also added. As a result, with an increase in the revolution of the crust, it decreases. And instead of at least a four.Time increase in the power of the spark, it turned out double (all by ear, by eye, approximately).

Iskra stretched up to 15 mm in the air. This scheme did not bring very great improvements to the starting properties (although the warmed engine could be started if the palm is very torn to the flywheel). That is, the frequency of sparking has greatly decreased. Almost like on a tractor magneto punching a spark with a hand.

But the main trouble has remained. The problem of the hot start, which on my mole always tormented me. 4 years, this scheme for faith served me. I all wanted to lose the generator coil. Try to look with less resistance. But somehow did not reach the hands.

And last fall I was visited by the idea that transformed the character of the motor. Twisting in the hands of Magneto, I realized that in the vacant place from the ignition coil, you can try to put a second generator coil. I had to work with a file, to hide part of the coil magnetic circuit and the seat on the magneto.

Registration of the ignition system

How to set the ignition on the Neva motornote depends on a number of factors. Nuances:

Primary configuration is made in conjunction with the first starting of the walk.Behind tractor. Secondary is carried out after any long work processes or downtime.

Before adjusting the ignition, it will be necessary to carry out the location of the walk.Behind tractor, as well as check all other systems of equipment.

Important! Ignition of the spark at the time of ignition is regulated by the distribution using the magneto cover, and the lower part of the mechanism interrupts it. For proper operation of such a function, setting and adjusting is required.

In this video, you will learn about the candles for the Neva walk.Behind tractor: when preparing the unit in working condition, how to check the ignition coil:

  • Initially, the flywheel workflow is checked to the contact opening point that occurs in Magneto;
  • The distance between the two parts of the system is measured. The “anvil” and “hammer”;
  • Rotation of the flywheel until the piston mechanism is compressed;
  • When the flywheel moves to the upper part, it is again rotated. Next, a single.Type knock will be heard, which indicates the work of a fence type;
  • The flywheel turns counterclockwise. The second mark should converge with the case mark;
  • The distance distance between the two contacts (fist and interrupter) is regulated. Each model gap has its own. For Neva, variation goes from 0.25 to 0.35 mm;
  • The fist is fixed with a special type screw located at the top.

Important! The standard ignition procedure is a mandatory procedure for the Neva.

Checking and repairing the ignition coils is a mandatory procedure, since after the adjustment of the engine starting becomes faster and smooth. This leads to slow wear of the piston system and other engine mechanisms.

These candles are suitable for the Neva motornote

How to diagnose and replace ignition coil with no spark on your mower.

MB 1 is the predecessor of the Neva and the same type of ignition option.

Important! The candle failure is the most frequent case of breakdown, so you need to have a spare version of the candle, which was checked.

All setting and adjustment of the ignition of the walk.Behind tractor is carried out only on proven candles, which were already in the work.

For engines like DM 1 or modifications, the list of the most suitable candles includes:

All these options have a thread size of 1.2 centimeters.

It is worth considering that profile candles from various famous brands are well suited. For example, B8AS.

Savings on candles with the technology of the MB class is unacceptable. The same goes for modifications like Neva.

  • The candle turns out;
  • Wiping electrodes with dry rags;
  • Fleet removal if any;
  • The gap is installed between the electrodes;
  • A square is fixed to the candle from the wires of a high.Voltage type;
  • The candle case is pressed to the head of the cylinder;
  • Next, the cranked is scroll through, and whether there is a spark.

In this way, you can check any type of candle.

Important! The clearance between the starter system and the magnetic shoe is from 0.1 to 0.15 mm.

If the gap has a different size, then it will need to be adjusted. It should be remembered that each type of motoblock has its own gap, but in MB modifications it is located within 0.1-0.15.

Do not forget about the gap

Neva type technique differs from similar motoblocks with increased wear resistance and efficiency, but it is required to check the ignition coil on the walk.Behind tract before the start of work.

The ignition coil is regulated in the standard way:

  • A4 album sheet is folded fourfold;
  • Two bolts are weakened at the module mount;
  • A folded sheet is laid under the pillow;
  • The pillow is poured, the fastening bolts are delayed;
  • The flywheel is turning;
  • The presence of a spark is checked;
  • The mechanism is fully installed.

If the motor.Cultivator undergoes major repairs or any replacement of parts, then the ignition of the motor unit of the MB is also checked.

On the checks of the gaps of the MB and further modifications, including the new model range of Neva, there are differences in the size of the necessary gap. Most are installed in the operating instructions, which is individual for different types of models.
