The voltage sensor consists of a rotor and a stator. Bolt the octane corrector plate to the distributor sensor housing. 6. Install the cover of the distributor sensor, check the correct installation of the ignition wires to the candles in accordance with the order of operation of the engine cylinders 1-2-4-3, counting counterclockwise. After each ignition setting, check the accuracy of the ignition timing by listening to the engine while the vehicle is moving.

Ignition system on UAZ 469

This mode is used when starting the engine with a starter. UAZ ignitions have a simple design. Contactless ignition is more convenient to use than contact ignition.

With anti-theft locking device, with blocking against restarting the starter without first switching off the ignition and with socket illumination. The locking device against restarting the starter must not allow the key to be turned again from position I (ignition) to position II (starter).

The operation of a car engine is impossible without a correctly set ignition timing. Rotate the distributor housing until the middle mark on the distributor body lines up with the mark on the engine. For example, for a VAZ-2106 car, the switch can be installed in a free space between the washer reservoir and the left headlight. Drill 2 holes and screw the switch with self-tapping screws. Correct installation ignition timing in a contactless ignition system makes it possible to operate the car in comfortable conditions. Set the crankshaft to a position that corresponds to an ignition timing of 5 degrees. Check connection order high voltage wires engine cylinders.

Underwater ignition UAZ scheme

And you can go further, throw out the regular harness, the EPHX system and install a switch in place of the variator under the hood. The output of the additional resistance "to the starter relay" in some wiring options is connected to the auxiliary contacts on the ignition switch, and not to the starter relay. The coil is for the contact ignition system! An interesting addition to the ignition system with an ATE-2 distributor and a Hall sensor will be the switch 962.3734 complete with a knock sensor (automatic octane corrector). The knock sensor is connected to the 7th leg of the switch, which is not normally used. The bottom line is that the eight distributor on the eight motor stands "from the ass" of the engine and is driven by a camshaft.

A pair of Hall sensors located at 90 degrees is placed in the distributor. relative to each other. A “butterfly” plate is put on the axis; when moving in the Hall sensors, it alternately generates pulses. Any distributor will fit, the main thing is that it fits the type of drive and is serviceable.

Recommendations for setting up a distributor Is it possible to put a distributor from the Volga on an UAZ Experience in operating a distributor with a Hall sensor (article) How to isolate the distributor from water? Alteration of non-contact ignition to contact Easily converted all electronic ignition to 31519 with a 3 l.1 engine. The regular electronic ignition distributor is replaced by a mechanical R 119-B;2. The regular ignition coil is replaced by B-117 A; 3. Regular switch and variator are simply removed; 4. If the contact ignition system, then wear of the bearing in the ignition distributor or an incorrectly set gap between the contacts is possible. You set the distributor slider to the first cylinder with a crooked starter, and the middle mark on the KV pulley (ZMZ 402) or the first along the pulley (UMZ engines) opposite the pin. Designed for installation on GAZelle and Volga vehicles with carbureted engine ZMZ-4026.10 instead of the standard ignition system.

STEP 4: Connect the wiring and install the switch. We insert the wires into the distributor.

Manual for replacing a distributor with an oil pump drive

Turn off the ignition and dismantle the cover of the distributor, tips and high-voltage cables are connected to it. Then, from the distribution mechanism, it is necessary to disconnect the wire connected to the switch. Taking a 13 wrench, unscrew the two nuts securing the device and dismantle it from power unit mechanism together with the oil pump drive.

What is the connection diagram for electronic or contactless ignition on the UAZ 417, how to convert contact ignition to contactless? Why does the coil heat up and how to adjust and adjust the lead angle? Also, non-contact systems are equipped with an electromagnetic device, which makes it possible to achieve more stable operation of the engine. One of the main nuances in terms of maintenance is the need for periodic lubrication of the distributor drive - at least every 10 thousand kilometers. After that, the cover should be removed from the distribution mechanism.

In order for the distributor to get into the drive, it is necessary to match the protrusions on the clutch from the bottom of the distributor with the slots on the drive shaft. On the installed distributor, there should be no gap between the octane corrector plate and the drive housing itself. Remove the cover of the new distributor. To do this, unscrew the 2 screws with a Phillips screwdriver. The slider should look at the engine shield. The fact is that the numbering of the 1st cylinder in the ATE-2 distributor does not match the numbering of the regular distributor. It is put on a regular place without alterations. STEP 4. Connecting the wiring and installing the switch There is nothing complicated. If a kit from VAZ-21074 is used, then without pads there will be only 3 contacts.

The main components of a contact type system are a battery, a short circuit, a drive, candles, a capacitor, and a breaker with a distributor. Non-contact ignition system, which is called transistorized. Unlike the two systems described above, the system electronic ignition It is characterized by a complex device that ensures the performance of not only the moment, but also other parameters.

8000 km. Tighten the nuts of the distributor and fastening the wire contacts. Rotor hub lubrication. 2. Remove the plastic cover from the springboard and make sure that the slider electrode matches the notch on the cover.

Some believe that the ignition system does not affect the power of the car. But is it really so? Obviously, if the ignition does not meet the needs of the car, it loses performance and reliability. Good technical condition of all parts and assemblies, as well as the timely supply of a spark - a guarantee that the car will reveal its full potential on the road.

Upgraded ignition systems help increase voltage because they require a wider gap between the spark plug electrodes. There are systems that use candles that give two or more sparks for more efficient ignition of the working mixture, especially on low revs engine.


Ignition adjustment
Most modern cars are equipped with electronic unit, it controls, among other things, the ignition system. On earlier models on-board computer no, respectively, a kit must be installed on them that distributes and delivers a spark.

Ignition control is very important. Fuel-air mixture must ignite, and for this you need a candle that gives out a spark at the right time. Normally, this happens just after the piston reaches TDC (top dead center). Of course, depending on the engine speed (up/down), this will happen at different times. There are other factors that affect ignition timing, such as air temperature, engine load, and throttle position.

If you advance the ignition, this will increase the power of the car, but can cause the engine to start to detonate and eventually break down.

Optimally set ignition eliminates engine detonation, reduces temperature exhaust gases and gives maximum torque.

Ignition coil
The coil generates and transmits a high voltage current to create a spark sufficient to bridge the gap between the electrodes on the spark plug. Modified coils transmit current better than regular ones, respectively, they are suitable for candles with a large gap between the electrodes. Most stock ignition coils have high revs motor is losing high voltage.


distributor
The distributor is equipped with a shaft, which is driven by a distribution or crankshaft. Inside the distributor there is a rotor. Its purpose is to distribute the spark supplied from the ignition coil to the candles. On top is a distribution cover that connects the distributor housing and spark plugs through high voltage wires.

Inductive accumulator for contact ignition system. It uses a contact breaker which, when opened, creates high voltage. It is distributed to the corresponding spark plugs by means of a rotor in the distributor. This type of drive is not bad for cars standard equipment, although it is not quite suitable for engines with higher performance due to the fact that it does not fully saturate the coil.


Inductive storage device for non-contact ignition system. It uses a non-contact sensor that generates voltage pulses and transmits them to a transistor switch. When the flux breaks down in the take-up coil, a high voltage is created. Non-contact systems can create more sparks per minute than simple ones. Therefore, they are better suited for vehicles with high performance engine.

Condenser Ignition System
The energy is stored in the capacitor instead of the ignition coil, although it is still used to transmit impulses. The distributor charges the capacitor, which in turn transmits current to the coil before the current begins to be distributed to the candles. This allows for more sparks per minute compared to a contact ignition system. In fact, the capacitor system can produce several sparks even at low engine speeds. It is installed on high-end cars.


Ignition system without distributor
installed on many modern cars. It does not provide a distributor, respectively, there is no additional weight and parts that could fail. The signal comes from the pulley crankshaft or from the flywheel, this is how the ignition timing is determined. The systems are good for high performance cars.


High voltage wires
The wires cannot affect the power of the engine. However, damaged wires that do not match the existing ignition system, or wires with the wrong resistance will prevent normal spark transmission. As a result, the performance of the car will decrease, misfiring will occur. Improved wires are more resistant to high temperatures.

Candle
The spark plug is the easiest thing to change. But, it was like that before. On modern cars, replacing a spark plug is a difficult and time-consuming process, since candles are often located in hard-to-reach places, for example, under a volume intake manifold etc. But good ignition impossible without good candles. Even a slight increase in the gap between the spark plug electrodes can produce a large spark, respectively. conventional engine it will take more air and fuel to react in the cylinders. On supercharged or turbocharged engines, high pressure is created in the cylinders, and, consequently, more resistance. Therefore, it is important to make sure that the selected spark plugs match the parameters of the car, and also remember that spark plugs with an increased gap between the electrodes require more voltage. Regarding the gap between the electrodes, we can say that it is fixed or the best option does not exist. Also, do not give preference only to cold spark plugs. Certainly, temperature regime is also important, but cold plugs are installed exclusively on cars with high performance. Although it all depends on the characteristics of the engine itself. According to recent data, very good candles Ignitions are iridium spark plugs.


Advice
On the standard cars it is not at all necessary to update or improve the ignition system. If the engine or other components have been tuned, you can replace the spark plugs and wires with improved ones. For sports cars it is recommended to replace the standard ignition system with a modified one.

Contact ignition is no longer installed on modern cars. There are many reasons for this, including the large number of mechanical systems in this kind of ignition. What should owners of old cars do? Sometimes they wonder if it is possible to convert a contact distributor to a contactless one?

Advantages of BSZ (non-contact system)

ATTENTION! Found a completely simple way to reduce fuel consumption! Don't believe? An auto mechanic with 15 years of experience also did not believe until he tried it. And now he saves 35,000 rubles a year on gasoline!

So, on the old-style distributor, due to the presence of a huge number of mechanical components, backlash and gaps appear over time. The energy of the spark is not provided as it should be, and the quality of the contacts themselves is called into question.

The installation of a contactless ignition system or BSZ can solve all the previous difficulties, since one hall sensor can immediately replace a group of various mechanical elements. Progress is a good thing, you can't argue with that.

Hall Sensor

Since we are talking about the hall sensor, we will consider those moments due to which it is considered significantly better mechanics, and even able to replace several of them.

Note. Interestingly, up to a certain point, this sensor could not be considered as an analogue of the mechanical component of the distributor.

However, over time, in the course of technological progress and the obvious shortcomings of the mechanical components, such as constant contamination, lack of contacts, etc., the hall sensor began to replace the previous systems. And today it is even put on scooters, playing the function of an integral part of the ignition regulator.

In essence, a hall sensor is a thin sheet of semiconductor. When a pulse enters it, a current with a low voltage appears. Voltage amplification is possible only if a magnetic field passes across the semiconductor. This property of the material was adopted by physicists.

The element consists of a semiconductor material (plate), a chip (microcircuit), a magnet and a metal screen with slots. It is through the last component that the magnetic field is passed, which is why energy arises. The metal screen, of course, does not let the magnetic field through, but when the slots open, a low voltage pulse is created.

An interesting point. When this device is combined with a distributor, a single unit called a distributor is obtained, which performs the standard functions of an ignition distributor with great efficiency.

Other benefits

The commissioning of the BSZ has become one of the major innovations in the automotive industry. This technical innovation allowed not only to increase the power power plant, but also reduce fuel consumption by several times. In addition, thanks to new system managed to reduce the amount of harmful substances emitted into the atmosphere.

KSZ or the contact system did not justify the hopes of the designers, because it was not possible to increase the energy quantity in the spark, and in the process of switching to more powerful engines such a distributor no longer justified itself.

In a word, high-precision ignition control with KSZ is impossible, the engine constantly has interruptions in operation, fuel consumption and CO2 emissions increase.

It is obvious that the supply of relatively more energy to the candles is considered by many experts to be almost the main advantage of the BSZ. Due to this, the spark increases, which is so necessary for the complete combustion of gasoline. And this, in turn, leads to an improvement in the maneuverability of the car on the roads.

The BSZ distributor is both a general improvement and pulse stability. At all ranges of ICE functioning, the return is significantly improved. The hall sensor in this case plays a much greater role, completely replacing the archaic contact system.

Finally, another indisputable advantage of the BSZ is its unpretentiousness and low need for maintenance. Adjustment of such a distributor will require only once, and not like KSZ - all the time.

Alteration of KSZ to BSZ will not take more than 1 hour, if you follow correct instruction holding. This applies, of course, to a person who is knowledgeable in auto electrics and who knows what difficulties he can expect along the way.

Any operation, be it repair or modernization, begins with the preparation of the workplace.

1. Decide where to install the switch. Many put it on the left mudguard, where it is fixed with two self-tapping screws to the body. However, you should be careful and make sure that the contact of the radiator of the device with the metal part of the skeleton of the car is to the maximum. Thus, the best heat transfer will be ensured.
2. Install the ignition mark on the 4th cylinder.
3. Purchase a new set of SZs that would fit the BSZ. The gap in such candles should be set to 0.8 mm.
4. Purchase and replace the coil.

It remains to change the distributor to electronic, install the hall sensor.

Arm yourself, of course, with the necessary tools:

• A set of various keys.
• Screwdriver set.
• Self-tapping screws.
• Drill with a set of different drills.

So, here's how the distributor changes:

• The cover is removed to access the rotor.
• Set the rotor-runner to a position that is easily repeated when installing a new BSZ-distributor. Mark on ICE.
• Fully unscrew the distributor lock and remove the device.
• Remove the main armored wire integrating the coil and distributor.
• Set the slider of the new distributor in accordance with the old one.
• Put the body according to the marks set in advance and marked on the engine body.
• Insert a new cover, connect the wires.

The coil is also updated:

• Using the figure-eight key, we unscrew the fisctor-nuts of the wiring of the contacts.
• The ten-key weakens the fixation of the coil itself.
• Install a new coil.

Attention. When installing a new coil, be sure to focus on the location of the contacts. It is better to put everything the way it was done on the old scheme.

• The new device is fixed.
• Wires are connected to contacts.

Advice. It is better not to remove the wires from the old coil yet, but to do this after installing the new one. Thus, it will be possible to transfer the wiring without making mistakes.

• The main armored wire is threaded, connecting the distributor with the coil.

One of the most important elements of the BSZ is the switch. As it was written above, its location is selected in advance. It is set as follows:

• The commutator leans against the body to mark the drilling locations.
• The device is screwed with screws.

Attention. Under one of the self-tapping screws, a black ground cable is threaded from the connection block.

In fact, in some cases, the secret of the alteration comes down to replacing the distributor rod. The old one is shorter. If you manage to rearrange this very rod from some new type of distributor, then as a result you can save a lot on buying a new distributor.

As for setting the BSZ of the distributor, it is carried out only once. UOZ can be set without any devices. This is done on an internal combustion engine warmed up to 85 degrees, while driving at medium speed. The gearbox shifts to 4th speed, the accelerator pedal is pressed to the floor. If a short-term detonation occurs, after which the motor picks up speed again, then the BSZ is set correctly. On the contrary, if a knock appears during this, you need to stop. The ignition is set incorrectly. And here's what to do:

• Rotate clockwise by 1 degree.
• Repeat driving with sudden speed changes.

A similar operation is repeated until the correct ignition is set.

That's all there is to it. Good luck on the road with the new distributor!

Installing a contactless ignition system based on a Hall sensor allows you to get a number of advantages that a contactless ignition system has over a classic (contact) ignition system. This replacement is relevant for early Volga models with installed engine ZMZ 402.

Advantages of the contactless system:

The beating and vibration of the slider in the distribution sensor practically do not affect the uniformity of the distribution of sparking over the engine cylinders;
The absence of moving breaker contacts in the sensor-distributor significantly increases reliability and simplifies Maintenance sensor (there is no need to periodically clean the breaker contacts and adjust the gap between them);
Providing the system with increased discharge energy, greatly improves the reliability of ignition combustible mixture in the engine cylinders, which is especially important in the acceleration modes of the car, when the conditions for the ignition of the mixture are unfavorable due to the temporary depletion of the mixture;
ensuring reliable engine start at low temperatures, significantly reducing the voltage in the vehicle's on-board network (BSZ practically does not cause a change in the spark formation parameters even when the voltage drops to 6 V).
The energy of the spark discharge when using the BSZ at medium crankshaft rotation speeds is 3...4 times higher than with the classical ignition system, in this regard, even a significant deposit of soot on the spark plugs does not significantly impair sparking in the engine cylinders.
The switch circuit protects the ignition coil from overload, increasing the reliability and service life of the entire system. After the engine is stopped, the primary winding of the ignition coil is forcibly switched off, which ensures the safety of the coil when the car is parked for a long time with the ignition on and the engine is not running.
Due to the fact that in the sensor-distributor there is no contact Group, at high engine speeds, a clear and uninterrupted sparking is provided, which is not in the KSZ.

In a contactless ignition system, instead of a contact ignition distributor, a distributor sensor or a hall sensor is installed. On the ZMZ engine distributor 54.3706-05 is installed. In the sensor-distributor, instead of the breaker contacts, a magnetically sensitive semiconductor element is used - an electronic microswitch (Hall sensor), whose operation is based on the physical Hall effect. To take into account the influence of engine operating modes (crankshaft speed and load) on the ignition timing in the design of the sensor-distributor, a centrifugal mechanical and vacuum automatic regulators are provided, similar to similar automatons of classical ignition systems.
The distribution of high-voltage pulses over the engine cylinders in the distribution sensor is carried out using a rotating slider.
The switching of the primary winding of the ignition coil in the BSZ is carried out by an electronic switch that converts the control pulses from the sensor - the ignition distributor into current pulses in the primary winding of the ignition coil. To increase the energy of sparking, the primary winding is made with a low value of active resistance (0.45 Ohm), due to which the maximum current in the primary winding of the ignition coil before the spark discharge reaches a large value (up to 10 A, instead of 3 ... 5 A for classical coils). ignition systems). Therefore, BSZ coils are not interchangeable with contact ignition coils. Their use in a classic ignition system will lead to immediate burnout of the breaker contacts.

To install the BSZ on the ZMZ engine, the following components must be purchased:

1. Sensor - ignition distributor (distributor) - 54.3706-05
2. Ignition coil from VAZ 2108 - 27.3705
3. Ignition switch from VAZ 2108 - 95.3734 (36.3734)
4. Harness of connecting wires.
5. High-quality high-voltage wires (optional, but desirable)
6. 2 screws.
7. Distributor gasket.

Installing the BSZ on a car is not difficult and it takes no more than an hour and a half to install it. First, carefully dismantle the old ignition system. Having unscrewed the distributor fastening nut, disconnected the low-voltage and high-voltage wires, disconnected the UOZ vacuum corrector tube - remove the distributor. We remove the sealing rubber ring from the old distributor, it will be needed to install it on a new distributor (there is no sealing ring included with the new distributor).
Disconnect the high voltage wire and the low voltage wires from the ignition coil. The wires going to the “K” contact (except for the wire going to the distributor) and to the “B” contact on the ignition coil are subsequently connected to a new coil (if you have a CVT system, then the coil can not be changed). The wire connected to the VC contact is insulated and is no longer used. We remove the ignition coil and, together with the distributor, put it in reserve.
Ignition installation begins with the installation of a new distributor. Putting a rubber sealing ring on it, we install it instead of the old one, having previously oriented the distributor drive with its counterpart. It will not work to install the distributor incorrectly (if you are not particularly zealous), since the groove where the counterpart of the distributor is inserted has an offset from the center. Having installed the distributor, we connect the vacuum corrector tube and high-voltage wires.
We find a place to install the switch (I installed it on the right mudguard near the GTZ). It is desirable that the installation site be as far away from heating parts as possible, and splashes falling into engine compartment when the vehicle is moving. We mark the attachment points, drill them and fasten the switch to two self-tapping screws. Then we fix the new ignition coil in place of the old one.

In the end, we get such a picture.

It remains to separate the wiring harness. There are a few points here that I would like to point out. Special attention. In the wiring harness that I purchased, the contacts were badly crimped and therefore I had to re-crimp them, and later, for greater reliability, solder (you can buy wiring from the VAZ 2107 in the store). All connectors must be firmly inserted and latched. It is important not to mix up the wires when connecting to the ignition coil. Connect the wiring harness as follows:

After installing the BSZ kit, you need to set the ignition timing. If all ignition components are in good order, and the installation is carried out without errors, then the engine starts immediately.

Although progress has stepped far forward, there are still many adherents classic models VAZ. These cars include an old penny, which has long been discontinued, and more modern, but also no longer produced models 2104 -. This article will discuss how contact ignition to contactless (electronic) and whether there really is any use for such a replacement.

Why is a replacement needed?

On the Web, in various automotive forums, owners have multi-page debates about the benefits contactless ignition. And these benefits are really enough. After installing contactless ignition, work becomes smooth and soft. At hard acceleration car has no failures. Starting is much easier, especially in cold weather. And of course, significant fuel savings.

The device and principle of operation of contactless ignition.

Basically, the device contactless ignition not much different from the system contact ignition. The only differences are the absence of a distributor and the presence of a pulse sensor with a transistor switch unit.

Installation of a contactless ignition system on a VAZ

To get started, you need to purchase a kit. contactless ignition for . We strongly recommend that you buy contactless ignition at trusted outlets. At the same time, you should pay attention that the kit must correspond to the characteristics of the engine of your car, and the length of the distributor shaft should not differ from the length of the shaft that is currently on the unit.

The contactless ignition kit should include:

1. distributor
2. coil
3. switching unit
4. connecting wires
5. set of high voltage wires
6. four spark plugs marked DVRM

To replace contactless ignition system passed successfully must be observed correct sequence performance of work. First you need to remove the negative. Then we disconnect the wires from the ignition coil and the central high-voltage wire, after which we remove the cover of the distributor. Now we set the slider to the position as shown in the figure, so as not to knock down the ignition settings. You also need to make a mark on the block in order to correctly set the new contactless ignition distributor. Please note that we put the mark in the middle of the five slots on the bottom of the distributor body. Now you can unscrew the nut and remove the old distributor contact ignition system.

Before installing contactless ignition, open the cover of the new distributor and put the slider in the same position as on the old one, perpendicular to the engine. And only then we insert it into the hole in the cylinder block. Then we combine the mark, which was made previously, and clamp the body with a nut.

Then we assemble: put on the cover, connect high-voltage wires.

Then we disconnect and remove the old ignition coil and put a new one in its place. We connect the other end of the central high-voltage wire to it, but the brown wire that went from the coil to the distributor is no longer useful to us and can be safely put aside.

We connect all high-voltage wires in their places. We connect two brown wires to the new ignition coil to the “K” terminal, and two blue wires to the “B” terminal.

Now we determine the place for the switch (it is possible in the area of ​​​​the washer reservoir) and fix it with the help of self-tapping screws. We connect the connector, and twist all the wires with electrical tape.

After the performed operations, start the engine and, if necessary, correct the operation of the contactless ignition.
