We carry out the wiring diagram for the electronic ignition on the UAZ. Electrical equipment of UAZ vehicles. Ignition Ignition coil UAZ 452

Any non-contact ignition system basically differs only by the manufacturer and has the following design features- this is a distributor sensor or simply a distributor, spark plugs and an ignition coil, a resistor (responsible for resistance), an emergency vibrator and a switch.

The distributor has a simple device consisting of a body, a cover (usually plastic), 2 regulators, a roller and a voltage sensor, and a corrector. The voltage sensor has a rotor and a stator. They have special marks for setting the initial ignition (primary).

The ignition coil has a primary winding resistance of 0.43 ohms and a secondary resistance of 13000-13400 ohms, at a temperature of about 25. The maximum voltage is up to 30,000 V on the secondary winding.
The transistor switch is the simplest device, consisting of a housing with a board, and the emergency vibrator has the same parts as the last, but it comes into operation when the switch fails.

Under what conditions to carry out maintenance

As a rule, the ignition needs to be serviced as soon as a malfunction is detected, but according to the regulations it is recommended for the mileage. 8000 km Tighten the distributor nuts and wire contacts. 16000 km Visual inspection of the condition, cleaning of visible elements from contamination. Lubrication of the rotor hub. 50,000 km Bearing cleaning and backfilling new grease, cleaning all parts from dirt, lingering wiring contacts.

How to set the desired ignition point.
1. The piston of the 1st cylinder must be at the top dead center, this is achieved by scrolling the camshaft, while watching the marks, they must match.

2. Remove the plastic cover from the springboard and make sure that the slider electrode is aligned with the notch on the cover. 3. The corrector plate is tightened with a bolt to the body, tightening is carried out until the pointer is in the middle of the marked scale. 4. The plate is loosened by the bolt holding it. 5. Turning the distributor body, and at the same time holding the slider, watch the marks on the rotor and stator (they must match), after which the plate is tightened again. 6. Collect everything in reverse order and check the vehicle for the accuracy of the ignition timing.

The engine warms up to working temperature(80-90 degrees), then choosing a flat and straight section of the road, hard pressing on the gas pedal, we accelerate the car. Having heard a slight detonation, we conclude that the adjustment was made correctly. With a noticeably greater detonation or no detonation at all, the following manipulations are performed - it turns the body clockwise in the absence and against it, with significant detonation.

Many UAZ owners are aware of the vagaries of the classic ignition, which sometimes brings unpleasant moments. And often craftsmen find ways to modernize a problematic unit or an entire system. And one such way to improve the do-it-yourself launch system will be discussed in this publication.

General concept

Ignition contact circuit in itself is not bad, because it is used by humanity with the advent of the first car. But before the possibilities contactless ignition she is, of course, far away. Therefore, many owners of UAZ, striving to improve the work power unit, reconfigure it.

And not only UAZs, but also others domestic cars, for example, a number of other brands and models are undergoing alterations.

Effect of modernization

Importantly, the engine compartment and interior wiring of the UAZ 31514 remains practically unchanged, and the alteration itself is characterized by the installation of new elements under the hood.

As a result:

1. The engine starts to work steadily in all modes;
2. Cold start is improved;
3. Fuel consumption is normalized;
4. The engine power reaches the nameplate.

Differences in ignition systems

The main difference between the two systems is in the moment of sparking:

• In a classic ignition, the slider under the distributor cover is responsible for this when it comes into contact with the output contact on the spark plug wire. In this case, the supply of a high-voltage pulse occurs with an increase. It is, as it were, lubricated, reducing the power of the spark on the spark plug electrodes.
• In contactless ignition the switch generates a charge and gives it out almost instantly when receiving a signal from the Hall sensor. As a result, the candle forms a more powerful spark. From domestic cars off-road Niva has a similar contactless ignition system - look.

Note! More powerful sparking contributes to the self-cleaning of the candle, because the fuel burns intensively, leaving no deposits.

What to buy

In fact, you need to buy a little, and if you have a working distributor and coil, then the shopping list will be minimal.

So, you need to buy:

1. Hall Sensor;
2. High-voltage wires (preferably silicone);
3. Switch from VAZ 08.

Advice: If your UAZ is already very many years old, then we recommend to buy a new distributor, coil to the already indicated list, and you will also need UAZ 31514 wiring with connectors for a switch.

For reconfiguration and operation, you will need and new scheme UAZ 31514 wiring, which is shown below in the photo, and which you can print for convenience.

You can also make the ignition system more powerful by upgrading it with two kits at once:

1. Two switches;
2. Two Hall sensors;
3. Two ignition coils.

With this approach, each subsystem will be responsible for sparking 2 cylinders at once:

• First and third;
• Second and fourth.

Most often, UAZ vehicles that take part in competitions or are used by professional fishermen and hunters are subjected to such a serious alteration. The video below shows how the engine works with such a system.

Advice: if you operate your UAZ 31514 in everyday life that is not related to extreme sports, then it will be enough to limit yourself to an alteration with one set - it is easier to maintain it this way. After all, it is used on domestic all-terrain vehicles.

Rework

Actually, the work itself comes down to reworking the distributor, which will no longer have a high-voltage part - an electronic switch will generate high-voltage pulses for it... The photo below shows the location of two sensors at once.

Pay attention to the shape of the contact plate:

• It has bent ends - the sensors are located vertically;
• Smooth - the sensors are mounted horizontally.

Both options are workers, it all depends on the design of the distributor. In the future, you only have to adjust the ignition. The instruction is simple - you must remember that the onset of sparking begins when the edge of the plate is in the center of the Hall sensor.

The order is as follows:

1. Crank the crankshaft until the piston reaches TDC in the first cylinder;
2. Turn the distributor body until the contact plate is in the sensor slot;
3. Tighten all mounting screws carefully to eliminate any looseness.
4. Start the engine.

Finally

If everything is done correctly, the ignition system will work stably and without problems. And your car will improve its performance. The price of the issue is cheap, since you will do all the work yourself. Good luck on the road common use and off-road!

Option UMZ 4216 with separate coils from the 406 motor. The main thing is not to confuse the places of the low-voltage control wires of the coils. The main thing is to know that the cylinder count starts from front bumper car.

The slider should stand against the inner contact of the cover, connected by a wire to the spark plug of the first cylinder. Closing the hole with a paper stopper, rotate crankshaft... The moment the plug comes out corresponds to the beginning of the compression stroke. Prolonged knock indicates an excessive ignition timing. The absence of detonation requires an increase in the ignition timing, after which the check must be repeated.

Starting the engine of any car is possible due to the ignition of the combustible mixture in the cylinders of the power unit. As already mentioned, the ignition on the UAZ performs one of the main functions when starting the power unit. 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. A contactless ignition system, which is called transistorized. How, after connection, is the ignition set for the correct operation of the motor? The next step is to reinstall the controller cover and diagnose high-voltage wires.

Turn off the ignition and dismantle the distributor cover, lugs 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 the mechanism from the power unit together with the oil pump drive.

Re: Numbering of cylinders at UMP 417

The voltage sensor consists of a rotor and a stator. The second terminal of the winding is electrically connected to the housing in the assembled sensor-distributor. 6. Establish a cover of the sensor-distributor, check the correctness of installation of the ignition wires to the spark plugs in accordance with the order of operation of the engine cylinders 1–2–4–3, counting counterclockwise. After each installation of the ignition, check the accuracy of the ignition timing by listening to the engine while the vehicle is moving.

Numbering from the radiator. Remove the spark plug from the first one, tighten it to compression (use your finger to check how it hisses), turn it until the ignition moment (according to the marks on the pulley), and look at the slider. Stick the first wire where the slider is, and the rest, respectively, in order along the slider.

I apologize for the lamer question, but the previous owner of the car claims that the numbering of the cylinders at the UMP 417 does not come from the radiator, but from the passenger compartment. Such was the current on the French.

And both valves of the first cylinder are closed at the same time? Timing gears by tags?

Put the TDC in 1 cylinder, remove the distributor from the drive (in the common people a boot) and look inside. It happens that the distributor drive is installed incorrectly. Try to put a very early ignition, if it gets better, then rearrange the distributor drive gear by 1 tooth. Just put the oil pump drive in place carefully.

Movement without interference: we set the ignition to the UAZ

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

The ignition system is a fundamental beginning for normal operation car engine... If some actions were incorrect, this will be reflected when the engine is started with a starter, the car is moving. And all you need to do is adjust the spark supply - correctly set the ignition on the contactless system. We tighten the bolt at the pointer on the housing of the distributor sensor. Be sure to check how the ignition wires to the spark plugs are installed, taking into account the order of operation of cylinders 1-2-4-3. In the absence of detonation, increase the ignition timing.

Serves to turn on and off the current in the primary circuit of the ignition system and to turn on the starter.

Trambler UAZ is considered one of the important components of the ignition system in vehicle... What is the connection diagram for electronic or contactless ignition, on the UAZ 417, how to remake contact ignition to contactless? Why is the coil heating up and how to adjust and adjust the lead angle? Also, the ignition system can be electronic. First of all, you must lock your car in one place, for this pull the parking brake lever.

The ignition must be installed if the ignition distributor is removed from the engine or if the ignition timing is violated. TDC according to the mark on the pulley crankshaft engine (Figure 15.13). The following are possible in the ignition system typical malfunctions: the ignition system does not work, the ignition system is intermittent, the ignition timing is broken.

This will be the beginning of the compression stroke in the 1st cylinder. 5. Replace the locking screw and check the contact gap again. 6. Install the rotor and secure the distributor cover.

With the help of an emergency vibrator, the UAZ non-contact battery ignition system can operate in the event of a failure or breakdown of the transistor switch or the stator coil of the distributor sensor. To switch to work with an emergency vibrator, it is necessary to disconnect the wire from the short circuit terminal of the switch and connect it to the output of the emergency vibrator.

This can be seen not only when starting the engine with a starter, but also during the movement of the car itself. After that, you need to check the installation of the ignition wires in accordance with the basic order of operation of cylinders one-two-four-three, it should be counted against (hour page). After you have installed the ignition, you need to check the correctness of its installation in motion.

Transistor switch.

And if the first one can be solved with the help of rollers and asphalt pavers, then with the roads - everything is MUCH DIFFICULT.

3. Turn the crankshaft to the start of the compression stroke. 6. Install the distributor cover and connect the high-voltage wires in accordance with the operating procedure for cylinders 1-2-4-3.

Additional resistance.

A drop in engine power is observed, fuel consumption increases noticeably and, most importantly, the car begins to shake and it may simply suddenly stall. If this is not the case, then we turn the crankshaft 180 degrees.

In trend:

STEP 1. Preparation

General view of the ATE2 kit:

You will also need, in addition to the system itself, a set of driver's tools. As a minimum, you need: open-end keys for 8, 10, a Phillips screwdriver and a "curve" starter (if a body lift is made or it is not possible to use a "curve" starter - you need something to turn the engine over).

STEP 2. Dismantling the native distributor sensor (hereinafter referred to as the distributor) and the ignition coil

Before removing the native distributor, it is necessary to crank the engine until the mark on the pulley "5o to TDC of the 1st cylinder" aligns with the pin on the block. We rotate the engine clockwise, align the marks and then remove the distributor cover. If the slider is directed towards the cylinder block, then you can dismantle the native distributor. If not, and the slider is directed in the opposite direction from the block, you need to turn the engine one more revolution. The slider now faces the engine.

To dismantle the distributor, remove the high-voltage wires and the hose of the vacuum regulator and use a 10 key to unscrew the bolt securing the octane-corrector plate to the drive housing and, shaking the distributor, take it out. If the effort of the hands is not enough, then we select a slotted screwdriver from the bottom of the octane-corrector plate, and, leaning on the drive, we move the distributor up.

Then we remove the standard ignition coil. We unscrew 2 nuts and remove the wires from the terminals. The coil itself is screwed to the motor shield with 2 screws.

STEP 3. Installation of a new distributor and ignition coil.

Before installing a new distributor, you need to mount an octane-corrector plate on it. This plate has no fixed position on the distributor body. The location of the primary unit is slightly to the left of the vacuum regulator body, when looking at the distributor from above. Putting the plate on the body, and setting its approximate location, tighten the nut on it with a 10 key. Thus, the plate compresses the body like a clamp.

Attention (!) - do not use excessive force, this material is very fragile!

Finally, the position of the plate is selected already during the setting of the UOZ on the engine.

The distributor is now ready to be installed on the engine. In order for the distributor to fit into the drive, it is necessary to achieve the coincidence of the protrusions on the coupling on the bottom of the distributor with the slots on the drive shaft. Place the distributor next to the drive and, turning the coupling by hand, achieve an approximate alignment of the protrusions with the slot on the roller.

Attention (!) - the protrusions on the coupling coincide with the slot only in one position, because the projections are offset from the center line.

We insert the distributor into the drive and, turning it from side to side, we achieve the coincidence of the coupling with 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 2 screws with a Phillips screwdriver. The runner must be looking at the motor shield.

The fact is that the numbering of the 1st cylinder of the ATE-2 distributor does not coincide with the numbering of the standard distributor. The output of the 1st cylinder at the new distributor is located above the Hall sensor block (there is a number "1" on the cover - this means the 1st cylinder). This is due to the fact that the ATE-2 distributor clutch is turned 180 °.

Then, turning the distributor body, we achieve that the connector of the 1st cylinder on the cover coincides with the contact of the slider. In other words - the moment of ignition of the mixture in the first cylinder. This will be the initial POP. Naturally, you cannot drive like this, but it is already possible to start the engine for adjustment. We tighten the bolt of the octane-corrector plate to the drive housing by hand.

Now we install a new ignition coil. Placed in a regular place without alterations.

STEP 4. Connect the wiring and install the switch

There is nothing complicated. If a kit from a VAZ-21074 is used, then there will be only 3 contacts without pads. Because in different schemes these wires are of different colors, then I will write their number. I count from left to right according to the switch contact numbers (switch location as in the 1st photo).

The wire from contact No. 3 (colors more often blue or blue with a red stripe) is connected to the positive connector of the ignition coil. On the coil, this connector is usually marked with a "+" or "B", or "BAT". The removed "+" from the standard coil must be connected to the same connector.

The wire from contact No. 5 (usually brown or black, this is the shortest "tail") is connected to any "mass"

The wire from the last contact No. 6 (usually brown with red or brown with blue) is connected to the second connector on the ignition coil. It can be designated as "K", "VK" or "RUP". A wire from the EPHH control unit (if any) is connected to the same coil connector.

2 connector blocks are connected to the commutator and the Hall sensor output on the distributor.

We insert the wires into the distributor. The order of connection is 1-2-4-3, starting from the output of the 1st cylinder. It should look like this:

It remains to find a place for the switch, because the length of the wires does not allow to put it in its regular place. If the car is not participating in the competition, then you can put the switch next to the fuse box. Completely reliable and available space... I put in the wires and fixed the switch under the dashboard at the feet of the front passenger.

It is also worth noting that not all digital tachometers that worked with a standard transistor-commutator circuit are able to work with a Hall sensor.

It remains only to adjust the UOZ and tighten the octane-corrector plate mounting bolt.
