Switch 131.3734 Connection diagram for a motorcycle. Ignition system. Ignition systems: from simple to the best

If you judge the materials of the conference, many Owaz owners changed the regular switch 13.3734 to Volgovsky 131.3734 or similar. At the same time, the mass of stories about how improved dynamics, efficiency, stability of idromic, etc.

I also decided to try, I took the bottle, opened "(c). A miracle, as expected, did not happen, because the engine already worked quite well, so it was decided to dare tolere and replace the sensations and impressions with more accurate data.

So, the initial positions. There are two switches: native - 13.3734 and 94.3734, the production of "Elara". There are diagrams of both, one of the manual, the other from the article. Datasheet on the L497 chip. Arrow ammeter and oscilloscope C1-94.

A decent amount of "information to reflection" (c) can be obtained by looking at the voltage oscillogram at the output of the switch. Therefore, the main efforts were aimed at obtaining it for competing devices. I ask to the pictures where the output voltage of both switches is sewn. Time parameters correspond about 1000b / min. Let's start with my native:

Spark as a spark. All in order - the release of high voltage, the breakdown of the gaps, the burning of the arc, the extinguishing of it after the exhaustion of energy in the coil, after some time the switch is turned on again and remains in this state until the next spark. The output transistor key has two states - turned on and off. Moreover, the duration of the turned off state decreases with increasing the number of engine speeds (sparking frequency).
Those. Almost all the time through the coil flows current flow, and if it is additionally not limited to it, it will also have to be bad (based on the coil parameters, the current can reach 20 with the Ampon's tail). Well, yes, the authors of the ignition system took care of this, and provided us with a restrictive resistor - a variator limiting d.C. Through the coil at about 7,5A. (The variator he, apparently, because it has a removal for closing its part when started.)

Consider the dependence of the current through the coil from the engine speed. It turns out that the most severe heat mode is idle. So, if you have a car for a long time working on small revolutions or on the XX - not to stay cold! Yes, the variator is located below the bobbin, additionally heats it.
On the plugged engine, but the switch turned on the switch periodically spontaneously generates a spark, slightly reducing the consumption current and facilitating the start of the engine on very small revolutions (in the frost or from the handle). Starting for dignity.

But the same tension formed by the Volgovsky switch. It is stiffer.
The cycle (phase 1) begins with the fact that the key opens. The current in the coil increases according to the exhibitor, striving for the 20a specified above. But does not reach them! Since the output transistor translates the L497 control microcircuit to the active mode (phase 2) and limits the current. Takes the feature of the variator. The variator is not needed! The transistor limits the current at 6a, providing constant energy inhibitable in reserves, and hence the spark. The variator with this switch is harmful! It does not allow current, especially under reduced voltage in the aircraft during the start, to achieve the limit value and disrupts the stabilization of the pulse current through the coil.

Little trouble - during the operation of the output transistor in the current stabilization mode, the power of about 50 W is dispersed! Not long, of course, but still ...
Finally, the transistor on the signal from the sensor of the traver closes - a high voltage pulse and spark is formed. The voltage pulse is higher than the 13th switch, but in short. Most likely, this is due to the fact that in parallel with the transistor they have condensers of different tanks. At the 13th 1MKF, and in the 131st 0.1MKF. But the square under the half-wave is close, i.e. Energy is about the same. And the duration of the spark is almost the same with the 13th. At the end of the spark, the key does not think to open (phase 4). The switch is waiting for the phase 1 calculated by the microcircuit of the control over the previous engine side. Those. Bo "Weight hours of the output switch transistor closed. At least on small circulation.
Look at the dependence of the average current through the reel from the revolutions. Here everything is "exactly the opposite" compared with the 13th switch. On the XX, the easiest mode for reels. Moreover, if the engine is stalled, after about 1 second, the output transistor will be closed by the microcircuit of the control. The consumption of the ignition system will equal to the consumption of the control circuit - Milliamper 50 ... But no sparking without a signal from the traver. If the engine rotates slowly, and the amplitude of the signal from the sensor is insufficient for the operation of the former - will remain without a spark!

A little about the L497 chip, invented by the glorious company SGS Thomson. This is a specialized analog-pulse computing device, where temporary parameters are set by condensers. These are not the most accurate and stable radio elements.
The microcircuit has the following functions, partially mentioned earlier:

• Control the angle of opening the output transistor.
• Output current limit.
• Limiting the output high voltage.
• Turning off the output transistor in the absence of a signal from the sensor.
• Formation of a signal for the tachometer.
• Protection itself from electrical overloads.

1. Dialectics are obvious. Each device has its own advantages and disadvantages. And both are not the masterpieces of ignition.
2. The energy of the sparks formed by both ignition systems is approximately the same. So with good candles, wires and rubble, you should not count on a noticeable improvement in the engine. The "Volgovsky" switch above the voltage of the breakdown and the cooler front of the high-voltage pulse, which they say positively affects the launchers and reduces the requirements for the quality of the candles.
3. A higher voltage formed by 131th increases the risk of a distributor cover breakdown and reduces reverse voltage reserve for the output transistor.
4. The 13th switch is easier, which means that more reliable. It uses an ordinary high-voltage transistor as a weekend, which in itself is more reliable than the Darlington transistor used with the L497 microcircuit. Moreover, with 50 watts, scattered at the collector while stabilizing the current.
5. The 131th switch provides more effective use Energy onboard network. The average current through the coil in the most used range of revolutions is less than the 13th. So, if you have a dream "gene", from the 131st you will leave almost twice the next. And the coil will be colder.
6. Put the engine is easier from the 13th. The spark is formed regardless of the speed of rotation of the KV!
7. Well, the last. If your ignition system is quite decently working, there is no reason to replace the switch to Volgovsky. And if she already "got it", try something more modern.

In the electronic ignition system, which is one of the most important components of a modern car, high voltage current is created and distributed due to electronic devices. Electronic system It has many explicit advantages, and also makes it easier to launch the engine in winter.

Ignition systems: from simple to the best!

The ignition system is an integral attribute of any gasoline or gas engine. With all the manifold technical nuances In this question, all ignition systems with the dynamic distribution of the supplied voltage can be divided into contact and non-contact. The following article is devoted to their main features, as well as reasons for the occurrence of systems with a static voltage distribution (electronic ignition).

Picky selection

Volga arsonists

Hello, editors? Advise anything: for six months, the third switch on the "Volga" change!

Mikhail Kolodochp

When such calls began to break out almost every day, the need for "disassembly" became apparent. Indeed, why start the ignition system so familiar "402-x" engines suddenly began to capricious on new "Volzhanks"?

Before grabbing the oscilloscope and soldering iron, we will make a brief but absolutely necessary

Historical excursion

Volga has always differed in identity. Having mastered in the middle of the eighties, non-contact ignition, it preferred a rotating magnet and a fixed stator winding. Such a decision demanded a switch completely not similar to "eight". As a result, the "Volzhsky" hoods materialized the scheme shown in Fig.1.

The system answered the principle of "easier nowhere". When the magnet rotates in the winding, a signal similar to a sinusoid is formed - recall the school lessons of physics. With a low signal level, the switch connects the primary winding of the ignition coil to the onboard network, and when high, turns off. The magnitude of the current in the coil does not care at all - it works stubbornly on the principle of the switch: "Opened - closed". And since the resistance of the primary winding of the B116 coil is only 0.43 ohms, then when it is directly connected to the on-board network, the current will reach 30 A - neither the coil, no switch in this mode and minutes. So that it does not happen to trouble, there is an additional resistor between the switch and the coil with a par value of approximately 1.2 ohms.

With the advent of VAZ 2101, it became clear that the modern motor in such convergents does not need - in the Togliatti registration resistor refused. But it turned out to be harder from Nizhny Novgorod, it turned out more difficult ... moreover, there is no simple resistor on the Volga, but two-piece! The first section wagged on the start - this is understandable, the "402-mu" engine should be helped. The second section is incorporated constantly - just say, not the best engineering solution.

The expulsion of the resistor from the contactless ignition "Volga" was delayed on a good decade. Finally, instead of the type 13.3734 switch under the hood of GAZ 3102 9 / "\u003e GAZ 31029 appeared almost the same as 131.3734, and a yellow box with three terminals disappeared. It is not surprising that even electrician specialists at first shrugged, and rumors crawled around the new product around the new product. One mysterious than the other. I was heard that the resistor was "hidden" inside the switch, which was "seized" on the race for savings for savings, as well as the fact that malicious details simply did not bring to the conveyor ... It is not surprising that many Mount-crafts began to correct The error "plant independently, returning the resistor" in place ".

Meanwhile, the new switch is an order of magnitude smarter than the old one. It automatically maintains the current in the primary winding. To do this, the transistor circuit has a small, but very important indicator resistance, the voltage drop on which tracks a special chip. If the current is small, the microcircuit "opens" the transistor, if large - "closes" it. The same microcircuit saves electricity, connecting the coil to the aircraft tie in time so that by the time of sparking it managed to accumulate the necessary energy. Finally, when the engine is stopped, the new switch will turn off the coil at all. As a result, despite the fact that instead of the variator resistor, the transistor itself is now fade, the power dissipated on semiconductors has decreased.

An interesting fact: when trying to connect consistently with the coil, the mentioned resistor 1402.3729 The power dissipated on the switch will not decrease, but will increase! The reason is simple - the resistor increases the "constant time" of the system, and therefore to achieve the desired current, the switch will have to work longer (Fig. 2). And why render the car "bear service"?

Options are possible

So, why the owners of the new GAZ 3110, who had chosen the good old "402th" motor instead of the unpredictable "406th", found no calm, but headache. Can you really get lost in three pines - switch, coil, resistor?

The background literature suggested that three types of ignition system can use three types of switches: 131.3734, 90.3734 and 94.3734. The market made amendment - our collection was replenished with a product with a long name 468 332 008 analogue 131.3734. In addition, helpful sellers as if incidentally suggested outdated 13.3734, 13.3734-01, as well as another strange product - 468 332 007 Analog 13.3734. The ignition coils turned out to be less - modern 31.3705 was added to the old B116. Resistor 1402.3729 special changes did not undergo.

It remains to solve a simple task - from seven switches, two coils and one resistor to make a brigade, able to control the ignition "Volga" and not to experience mutual allergies.

First we will deal with the coils. Electrical parameters B116 and 31.3705 practically coincide, so any of them can ride "Volga". At the same time, the oil-filled "old woman" B116 has a higher vitality in overheats and other troubles, and therefore it is not worth sending it to a retirement.

Swiss switches in two groups - "old" and "new". "Old" (photo 1-3) do not know how to adjust the rise time in the coil, "new" (photo 4-7) should be able to be able to all.

From the "Starichkov" the most "firm spark" turned out to be Staroscolsky (photo 1) - thoughtful and tested design. Ulyanovskaya product (photo 2) with the appearance almost the same, but worse. As for the other "Ulyanovka" (photo 3), this is a complete failure. Those who made the case of a plastic switch did the power transistor (by the way, it is without labeling) on \u200b\u200bmartyrdom in slow fire: the heat sink area has decreased by three times ...

Go to "contemporaries". Staroscol traditions are inherited - to the switch 131.3734 (photo 4) there are no complaints. Inheritance traced in Ulyanovsk (photo 5), but there is nothing to rejoice here. A parody of the indicator resistance is added to the disgusting heat sink in the form of a printed conductor on the board. Kaluga switch (photo 6) is made in good faith. Indicator resistance - purchased, with a stable characteristic. The ancient "Cheboksaret" (photo 7) did not like frankly. Indicator resistance - as a slim spiral from a thin copper wire. Maintainability Bad - Screws soldered to the board. And the vertically installed elements can easily fall off when shaking.

Thus, from the four "contemporaries" on the Volga can ride two - "Staroscole" (photo 4) and "Kaluzhanin" (photo 6). Resistor 1402.3729 They are contraindicated, and the coil can be any - both B116 and 31.3705. Unfortunately, under the hoods of the current "Volzhanok" periodically searched with a frank halants, ruthlessly killing memories of the once-tucked car.

Contactless transistor ignition system GAZ-3307.

First of all, let's get acquainted with the gas-3307 truck ignition system. GAZ-3307 ignition system - battery, contactless transistor with voltage in the primary chain 12V, consists of sources electric current, ignition coils, added resistor (if I'm not mistaken where since 2000 is available without an additional resistor), switch, ignition distributor, spark plugs, candle tips, ignition switch and low and high voltage wiring.

Technical characteristics of the gas ignition system GAZ-3307 (GAZ 53)

Ignition procedure GAZ-3307 1 - 5 - 4 - 2-6 - 3 -7 - 8 ignition distributor type (rubber) - 24.3706 Rotation rate of the distributor roller in 1 min with uninterrupted spark formation when working with the ignition coil B116 on a three-electrode arrester when spark gap 7 mm, min-1 - 20 - 2300 direction of rotation roller ignition distributor (rubber) GAZ-3307 - clockwise ignition coil GAZ-3307 - B116 ignition candles - A11 spark gap in candles, mm - 0.8 - 0.95 Additional Resistor - 14.3729 Switch - 131.3734 or 13.3734 Candle Tip - 35.3707200

GAZ-3307 ignition system scheme

So. As I have already spoken in our time, the gas-3307 truck, the ignition system has suffered small changes.

As I already wrote it happened after 2000, it's about I say. I will not say for sure I'm afraid to make a mistake. And google-looking for no time for it is simply no yes and especially not interesting. If you are interested in looking at me later, they will also share with me. You can leave a comment.

This concerns the transistor switter of brands 13.3734 and 131.3734

The difference see only one digit that is, 13.3734 is up to 2000. And they began to produce GAZ-3307 after 2000 with a switch 131.3734. And just one digit and this is one digit. i.e. as you noticed. Figure 1 removes gas-3307 from the ignition system additional resistor - 14.3729.

That is, simply put the function extension resistor - 14.3729. Built in transistor switch 131.3734.

I want to warn you someone can say "Yes, I put it instead of the brand 131.3734, and nothing works," I agree with him.

GAZ-3307 of course will work and go fine but not far away. And why. You ask, of course. And you will be right to learn why. Yes, because you just will simply break the ignition coil (Bobin).

Why this will happen. Ignition coil. GAZ-3307 (B 116) is a transformer, on the iron core of which the secondary winding is wound on top of it. The core with windings is mounted in a sealed steel case filled with oil and closed with a high-voltage plastic lid.

Operating temperature from -50 ° C to + 80 ° C. Resistance value at a temperature of 25 ° C: primary winding (0.65 + 0.07) Ohm, secondary winding (18 + 1.8) com.

Developed secondary voltage of 18 kV Max. Power supply 12 V. Weight 0.95 kg. When working ignition Coil B-116 additional resistor-14.3729. The resistor during operation is heated, this is normal. Resistor. When the starter is turned on (when starting the engine), the coil is shuled and the coil is powered by a full voltage (more precisely on the onboard, created starter) makes it easy.

After turning off the starter again takes for "work" additional resistor-14.3729. And then take yourself such a picture of GAZ-3307 Well, let's say after 2000 release there of course ignition without extension resistor-14.3729 and ignition Coil B-116 and transistor switch 131.3734, And you took and set transistor switch 13.3734, And that, then the GAZ-3307, of course, it will be necessary to go out normally normally (as I have already expressed above) is not far away the coil. That is, reduce the onboard tension. For the ignition coil, no longer anyone.

And how we are already known ignition Coil B-116 powered by reduced voltage through additional resistor-14.3729 or with the added voltage drop function transistor switcher brand 131.3734.

And in consequences ignition Coil B-116 Just braid.

I still can not notice such a moment. There is still a ignition coil B-114
As you noticed, it is not different from the B-116 (some put it) it is also suitable for gas 3307. But I personally do not advise you to put it. GAZ-3307 Of course, it will work (checked yourself. I had to arrive with the ignition coil B-114 to the house. When B-116 burned) if you put it and eat it or you may not feel the difference. But in the end it will affect the fuel consumption (increasing) and of course on the car traction (decrease), the engine will work unstable. Quite simply ignition Coil B-114 Designed for GAZ-53 with contact-transistor Ignition system

And so friends we are with you. As I think. Finished familiarization with the gas-3307 truck ignition system (GAZ-53). If suddenly you have any questions you can leave comments.

And now let's understand what reasons are lack of spark.

If suddenly, you did not find something, or you simply do not have time to search, then I recommend getting acquainted with the articles in the categories "Gas Repair". I am sure you will find the answer to your question, and if not write in the comments of the question you are interested in. I will definitely answer.
