How to regulate ignition on gas 53. Contact transistor car ignition system. Video "Installing a gas traver"

the main / Battery

Principle of engine operation internal combustion (DVS) is based on the transformation of energy released in the process of combustion of fuel into the mechanical movement. DVS received widespread use. IN gasoline engines In order to ignite the combustible mixture, a spark is needed. Any ignition system is designed to provide timely and high-quality fuel combustion, and gas 53 is no exception.

Device

Car Ignition System GAZ 53 is currently non-contact. After examining the device and principle of operation, you can simply master the skills of finding and troubleshooting. Especially, it is necessary for those who exploit GAZ 53. After all, it often happens that there are no good specialists nearby who would help in solving the problems that have arisen. In addition, their services will have to pay. The quality of the work done can be determined sometimes after a while. A malfunction that occurred unexpectedly and at an inappropriate moment will create trouble.

Elements of the system

The gas ignition system of GAZ 53 consists of several elements, each of which performs its function. Knowing them, you can find much faster and eliminate a malfunction. The system consists of the following elements:

BATTERY BATTERY;
Switch;
Spark plug;
Sensor distributor;
High-voltage and low-voltage wires;
Ignition coil;
Additional starter relay;
Additional and interference resistor;
Current pointer;
Egnition lock.

All component elements can be grouped depending on the tasks being performed. In this case, they will be included in the relevant groups. The gas ignition system of GAZ 53 will work correctly when the main conditions are followed:

Comparison of the moment of the spark and engine operation;
Sufficient spark power;
Lack of skips in sparking.

For a timely supply of sparks, it is necessary to carefully relate the engine work tact and the appearance of voltage on the electrodes of the candle. The desired power of the spark, in turn, depends on the magnitude of the voltage, the gaps between the electrodes of the candle and the condition of the chain. The absence of sparks leads to a reduction in power and an increase in fuel consumption, so the skips are not allowed.

Timely spark

Comparison of a certain tact and supply voltage to candles is the task of the distributor sensor. The contactless gas ignition system of the car 53 can be equipped with a magnetoelectric or semiconductor distributor sensor, which is inside the distortion. The list of elements of the tramblor includes:

Sensor distributor;
Tok offshore plate (slider);
Centrifugal and vacuum regulator.

The magnetoelectric sensor GAZ 53 is an AC pulses generator, the frequency of which depends on the rotor of the engine. This device has eight poles (by the number of cylinders). In the process of rotation distribution ValaAnd with it and the sensor rotor occurs a consistent passage of the poles of a constant magnet through the poles of the stator winding. As a result of a changing magnetic flux in the winding, an induction is guided in the winding, which creates a control pulse for the switch.

The centrifugal regulator rotates the sensor rotor relative to the stator, which, in turn, changes the ignition ahead of the gas 53. This happens when the engine crankshaft rotation rotation increases. Georgs of the regulator, overcoming the force of the springs, rotate the rotor. Thus, the effort must be defined, otherwise it will affect the operation of GAZ 53.

The vacuum regulator rotates the stator relative to the rotor, changing the angle. It works depending on the load and turns of the engine.

Power and quality spark

It's no secret that a good spark is a key to high-quality flammability of a combustible mixture. The gas ignition system 53 will have a good spark if there are the following conditions:

The clearance is properly adjusted between the candle electrodes;
Good ignition coil;
The desired form of switch pulses;
Good quality high voltage chain.

Too small gap between candle electrodes will result in the inflammation of the fuel and air mixture it will be difficult. Because of this, there may be a pass not in sparking, but in ignition. The consequences are the same.

Excessive big Clearance Increases the total resistance of the high-voltage chain. Because of this spark, sometimes it will disappear. Optimal option There will be a necessary gap. It will provide good spark at other conditions.

The serviceability of the ignition coil is manifested in its ability to induce the necessary voltage without interruptions (skips). As a rule, a faulty coil makes itself felt on a characteristic reduction in the quality of work of all eight cylinders. If it is established that the coil is faulty, then it is necessary to change it on the same type, the same marking. This detail of GAZ 53 is two windings: primary and secondary. The latter contains much more turns than the first. The windings are wound alone on top of another on the magnetic circuit. The whole design is in a sealed case, filled with plastic. The malfunction of this part is associated with a closure that can be intercity and on the housing.

The gas ignition system of GAZ 53 will not work qualitatively if the shape of the switch pulses entering the primary winding of the coil will be incorrect. The amplitude and forms of the primary voltage depends the rate of decrease in current, and, consequently, the value of self-induction EMF, which affects the spark. It is possible to check the correctness of the pulse form, only having an oscilloscope and exemplary waveforms.

The quality of the high voltage circuit is the reliable contact of all compounds, the absence of closures on the entire length and the necessary resistance value, which must be distributed to reduce the interference from the operation of the gas ignition system 53. This is possible when the rules for replacing the elements to new ones.

The gas ignition system GAZ 53 needs a periodic inspection. It is necessary to check the quality of the landing of high-voltage wires into the sockets of the coil and the distributor. If there is a weakening of contact, then it is necessary to break the connectors of the wires and insert them into the socket. The breakdown of the ignition coil is most likely if it is covered with a layer of dust, dirt or in water. Therefore, if possible, you need to avoid. Finding a gas 53 with an inclined ignition and a non-working engine can lead to a break of the coil.

The fact is that the voltage in the primary winding when the ignition is turned on and disabled Engine There is always, because the breaker sensor does not work. When buying new spark plugs, it is desirable to install the recommended manufacturer, pre-checking the gap between the electrodes. If necessary, adjust it. Replacing elements to new ones with another labeling can lead to the failure of other components of the system. It is necessary to periodically lubricate the distributor roller through the existing masl.

Maintenance Ignition GAZ-53, GAZ-3307

To protect the possible breakdown of the plastic cover, the coil must be cleaned from dirt, dust and oils, check the reliability of fastening of high and low voltage wiring.

When the engine is not working, it is impossible to leave the ignition on to avoid overheating coil, leading to its failure. The use of other types of ignition coils is unacceptable.

The causes of the ignition coil fault can be: insulation test; Interviton closure; Squares and cracks of the plastic cover; The root of the cover, the ignition coil due to the undone high voltage wire in the nest.

In the windings of the ignition coil, the defects most often appear due to their overheating and working with increased gaps of candles. Overheating is mainly when the ignition is turned on and the engine unused.

Before removing the ignition coil of GAZ-53, GAZ-3307 for replacement, you should make sure that the wires are configured and reliable to connect the coils. Checking the coil follows a special stand in conjunction with a transistor switch, an additional resistor and a distributor.

Ignition distributor (rubber) GAZ-53, GAZ-3307

GAZ-53 car rubber, GAZ-3307 (24.3706) (Fig. 2) is a generator that produces voltage pulses to control the transistor switch and to distribute high voltage current pulses for ignition candles.

The rubber automatically adjusts the magnitude of the ignition depending on the engine speed and from the load. Automatic adjustment of the moment of ignition, depending on the revolutions, is carried out by a centrifugal regulator, and from the load - a vacuum machine.

In the housing 1 in two sleeves 26, a roller 27 is installed on the top of the shaft, the centrifugal regulator with the rotor 10 is mounted on which the magnet 9 is installed. The runner 15 is installed on the top of the rotor. .

From above, the housing is closed with a lid 11, in which there are conclusions for high voltage wires from candles and ignition coils. The ignition distributor shaft 27 is driven by the switchgeal gear.

The centrifugal ignition protrusion of the GAZ-53 traver automatically changes the ignition advance angle depending on the rotational speed of the engine distribution shaft.

The inconsistency of the ignition advance angles is usually associated with the jewelry of the centrifugal regulator, or with the weakening of their springs and causes detonation, reducing the engine power, as well as an increase in fuel consumption.

The vacuum ignition timing regulator automatically changes the ignition advance angle depending on the engine load.

Manual adjustment (when installing the ignition) is carried out by turning the GAZ-53 trambrel in the drive case. For turn, you need to release the traver fastening bolt.

Rotate the ignition distributor for one division of the scale corresponds to a change in the angle of ahead of 4 ° (at the corner of the rotation of the crankshaft).

Ignition installation GAZ-53, GAZ-3307

To install the ignition of GAZ-53, GAZ-3307 with the drive removed from the engine and its drive is necessary:

Set crankshaft To position V.M.T. the end of the contraction in the first cylinder; Put the dispenser drive to the engine;

Install the ignition distributor on the engine and high voltage wires; Install the moment of ignition.

The order of attaching high voltage wiring from the traver to candles is shown in Fig.3.

Fig.3. The order of connecting wires to the candles of the ignition distributor GAZ-53, GAZ-3307

A - in front of the car

Setting the moment of ignition GAZ-53, GAZ-3307 is made after installing the distributor in the following order:

Install the crankshaft to the position at which it will go to 4 ° V.M.T. The end of the stroke of compression in the first cylinder, which corresponds to the position of the pointer against the fourth risks on the crankshaft pulley;

Loosen the ignition distributor drive fastening nut;

Remove the lid of the traver. Press your finger to the slider against its rotation (to eliminate the gap in the drive), carefully turn the dispenser (traver) housing before combining the red labels on the rotor and the stator and in this position secure the nut holder nut.

Setting the moment of gas ignition GAZ-53, GAZ-3307 should be performed with great accuracy. The presence of even small inaccuracies causes increased flow Fuel, water drop drop.

In addition, there may be cases of breakdown of the cylinder head laying, roasting pistons, valves and other phenomena caused by detonation.

Therefore, the adjustment of the moment of ignition is made on the road when driving. This is done in this way: the engine warms up to the fluid temperature in the cooling system 80 - 90 ° C.

Moving on direct transmission by roven road With a speed of 25 km / h, to dramatically click until the throttle pedal failure and give an acceleration machine to 60 km / h.

If at the same time there will be a slight and short-term detonation, disappearing at a speed of 45-50 km / h, then setting the moment of the ignition is correct.

With a strong detonation, turn the gas-5 gas distributor body, gas-33073 to one division of the octane-corrector scale clockwise (each division of the scale corresponds to the rotation of the crankshaft at an angle of 4 °).

With the absence of detonation, turn the dispenser's sensor housing to one division counterclockwise. After adjusting the moment of ignition, check its correctness, listening to the engine when the car is moving.

You should always adjust the ignition installation that gives the engine with a large load of just a light detonation. In case of early ignition, when severe detonation is heard, a block head gasket can be broken and valves and pistons can be burned.

With a late ignition, the fuel consumption increases sharply, and the engine overheats. More accurate installation Ignitions are produced using a strobe.

To increase the durability of the interrupter's contacts and ensuring uninterrupted ignition, currently on GAZ-53A cars, ZIL-130, ZIL-131A are installed. It consists of rechargeable battery GB, ignition switch, block of addition resistors S.E-107, TK-102 transistor switch, B-114 ignition coil, R4-D distributor for ZIL or P13-D vehicle for GAZ-53A (without capacitor) and.

The addition of additional resistors limits the current in the coil and consists of two resistors R3 and R4. Resistor 3 when starting the engine shrouded.

Fig. Scheme of contact transistor ignition system

Ignition coil ignition. It has an increased transformation coefficient and the reduced inductance of the primary winding. One end of the secondary winding is connected to the coil housing.

The main purpose of the transistor switch is to turn on and off the low voltage current in the primary winding of the induction coil.

Interrupter contacts PR serve to control the transistor switch (unlocking and locking the transistor).

In the transistor switcher installed:

powerful Germany transistor
the primary winding of W1 which is connected to the transistor base and the interrupter
the secondary W2 winding, a baked R2 resistor connected to the transistor emitter
cONDENSER C1 with R1 resistor
silicon Stabilion V3 with Germanic Diode V2
electrolytic capacitor C2.

When the ignition is enabled and the closed contacts of the interrupter through the transistor flow two currents:

Control current The circuit flows: "+" rechargeable battery, the ignition switch, the addition resistors R3 and R4, the primary winding of the induction coil, the emitter transition is the transistor base, the primary winding of the pulse transformer, the interrupter contacts, the "Mass" of the engine, the minus the battery terminal. The control current, passing in direct direction through the emitter transition and the database, unlocks the transistor (dramatically reduces the collector transition resistance) and opens the path of the primary winding of the induction coil.
Primary winding current It flows from the positive terminal through the ignition switch, the added resistors, the primary winding of the coil, emitter and collector transitions of the transistor and then on the "mass" and "-" rechargeable battery.

At the time of opening the interrupter contacts in the transistor control circuit disappears and the resistance of the emitter and collector transitions increases sharply, while the transistor is locked and turns off the current winding current of the induction coil. The fading magnetic field of the primary winding of the induction coil creates a high voltage in the secondary winding, which through the distributor is supplied to the spark plug.

The IT pulse transformer serves to speed up the transistor locking when the interrupter contacts are blurred. At the time of opening the contacts, the fading magnetic field of the primary winding of the IT transformer permeates the rear-winding of the IT secondary winding and induces an EDC in them, which creates an inverse (negative) voltage on the emitter transition transistor.

For the protection of the transistor from heating and breaking the self-induction currents of the primary winding of the induction coil arising from the locking of the transistor, the protection chains are provided. The C1, R1 circuit absorbs the energy of self-induction and removes it in the form of heat through aluminum heat sinks. The self-induction currents charge the capacitor, then the oscillating discharge occurs through the primary winding of the induction coil. This increases the duration of the spark discharge between the electrodes of candles.

The chain consisting of a diode V2 and Stabitron V3 protects the transistor from overvoltage and breaking the self-induction currents of the primary winding of the coil.

For better heat outlet, the body of the device is cast from an aluminum alloy with a ribbed surface, and the transistor and the elements of the protection chains (C1 R1, V2, V3) are fixed on heat sinks connected to the housing. The transistor with elements of protection chains is filled with epoxy resin.

Pros of contact-transistor ignition systems:

large output voltages due to increasing current in the primary winding and less electrical load on the contacts of the interrupter
the gap between the candle electrodes is increased to 0.85 ... 1.0 mm, which makes it possible to work on disens work mixtures and due to this reduce the toxicity of exhaust gases
lightweight Start and Increased Engine Reliability at Small and Large Rotation Frequencies
big Durability Interrupter Contacts

Each motorist knows that the ignition system in any car is needed to influence the combustible mixture in the motor. Not exception are and trucks GAS. In this article, we propose to find out which GAZ-53, with what faults the car enthusiast can encounter and how to configure it.

[Hide]

Basic elements of the system

To know how the system is adjusted and configured correctly, we recommend first to get acquainted with the device. GAZ-53 trucks are equipped with contactless NW.

Such BSZ is a battery, since it contains current sources, in particular, we are talking about:

battery AKB;
the coil itself;
switching device;
interrupter dispenser;
candles;
element of the resistor;
switch SZ.

Tuned truck GAZ-53

Any SZ truck gas includes two chains: high and low-voltage.

The main components of the low-voltage network are:

Battery by 12 volts.
Cable battery with terminals. Cable data are multiple and characterized by a large cross section.
Directly the lock performing the power supply function to the chain.
The contactless is equipped with the ignition distributor of the ignition distributor, mounted in the rubble. In the event that the system is contact, then the function of this component executes the pulley of the traver, as well as contacts. In addition, instead of the interrupter, the Hall sensor is sometimes mounted.
Committor designed to provide stable functioning power aggregate.
Resistance designed to ensure normal starting of the motor and unloading the operation of the gas ignition coil when the power unit is operating at high speed. Thanks to this component, the coil cannot overheat.
Primary winding.

As for the secondary site, its composition includes such components:

secondary winding;
the distribution element, which consists of pulley, cover, as well as the slider;
transmitting a signal to the candles;
candles.

When the lock is activated on the primary section, a magnetic field begins to form a magnetic field in the design of the interrupter. When the trambling shaft spins, then in this section of the circuit, the current is interrupted, respectively, the formed field disappears. At this time, a signal begins to appear in the winding chain, which is subsequently separated by cylinders.

Electroshem SZ. vehicle GAZ-53.

System breakdowns

For what reasons, devices occur in the operation of the device:

The breakdown of the switch, which either breaks, or is very hot. Such a breakdown is considered a "illness" for these cars, drivers write about it in their reviews. Because of overheating ceases to be a spark, and this leads to the fact that the motor does not work. Only when the switch will cool, the motor can be started.
Thring high voltails. In the event that the cable is poorly installed in the lid, the power unit may function incorrectly. If we examine the DVS in the dark, you can see the punching cable by the appearance of the spark.
Problems in the functioning of the interrupter-distributor, in particular, we are talking about burning its lid. It should be noted that this component of the structure sometimes burns in the place where coal with a spring is installed. When checking, it is advisable to pay attention to the condition of the cover 0 any cracks and damage must be absent.
Another problem is to burn the contacts of the runner on the rubble.
Problems in the diaphragm on a vacuum regulator - it can skip. Because of this, the engine power will be reduced, and if you hit the gas sharply, then the car will begin to "chop up".
Overheats the coil directly. This type of breakage, as a rule, testifies to the inoperability of the coil, sometimes it can be associated with the switcher.
Candle failure.

Self adjustment

If the ignition later, the problem can be solved on your own. To adjust the dispenser drive, you must correctly install and set the labels.

The drive installation is as follows:

To begin with, install the piston of the first cylinder into the upper dead point. The crankshaft turns until the labels on its pulley are aligned with the top point label.
After the crankshaft turns until the moment when the tags on the pulley are not aligned with the label 9 on the pointer.
Next, you should weaken the screw fixation screw of the upper plate of the corrector to the interrupter. It is necessary to connect the control lamp to the terminal of the interrupter and the mass. Ignition is activated, after which the housing of the interrupter turns against the clock arrow until the lamp starts to burn
Next, you need to tighten the lock fixing screw and put the rotor with the lid. A wire to the first cylinder candle is connected to the rotor plate. All other cables must be connected to the arrow of the clock, while observing the functioning of the cylinders themselves. That is, the first, fifth, fourth, second, sixth, third, seventh and eighth. , the crankshaft should be checked in such a way that the mark on its shaft does not reach the central tag on the pointer to the NMT (author of the video - Nail Poroshin).

It often happens that even after adjusting the electronic SZ, the motor is still overheated. The power unit loses the thrust, it begins to increase gasoline consumption, there may be interruptions in the engine.

The problem allows you to solve the adjustment of the angle of the system at a running engine:

When the power unit works on idlingYou need to get to the screw fixation screw. Using a wrench on 10 to weaken it.
Then rustually in the direction counterclockwise. Screw should be fixed.
Pressing the gas pedal, check the pickup of the power unit. If you hear that the power unit began to detonate, that is, a ringing appeared, the rubber move back. The practical method you need to set the desired angle.
After that, the operation of the power unit must be checked during the ride. If the motor began to work in normal mode, it can be considered that the adjustment process is successfully completed.

For stable, economical engine operation is greatly correct. To completely reckon fuel, a spark discharge in the ignition candle should be before the upper dead point of the cylinder piston, since it is necessary to combust the fuel combustion. The angle of rotation of the crankshaft from the moment of the occurrence of the spark discharge to the upper dead point is called the ignition advance angle.

Installing the ignition system.

To start the engine, it is enough to establish ignition at the time of passing the piston of the upper dead point or close to this point. Installing the ignition system It is required when removing the trambl on VAZ cars and removal of the drive of the battle on cars GAZ, ZIL, AZLK, etc.

Ways to install the ignition.

For setting the ignition system There are two ways.

The first way to install the ignition.

The first way comes to all engines with contact or contactless system ignition. For installation, the candle of the first cylinder is twisted, and the hole is stuck with his finger (when installed with an assistant) or not a tight tube of paper or other material. After that, the engine rotates with a clockwork handle, and when it has no raised drive wheels when the transfer is enabled. Increased pressure in the cylinder under the finger or knocking out the tube means the movement of the piston up when the compression tact.

After determining the compression tact, it is necessary to combine the tag of the upper dead point. Location of labels individually for each engine. For engines, GAZ-402 methows are located on the crankshaft pulley and the front cover, the engines of GAZ-52, GAZ-66 are located on the flywheel and the Mohovik casing.

After installing the upper dead point, it is necessary to set the trambler in such a way that the slider would be aimed at the output of the first cylinder of the lid of the spend. When installing the gas ignition system, the UZMU with a contactless time, it is necessary to combine the label on the anchor of the arrow of the arrow on the stator.

If all actions are performed correctly and no malfunction of other systems, the engine must start.

The second way to install the ignition.

For four cylinder engines You can not define compression tact for the first cylinder, but it should be borne in mind that when installing the tip of the upper dead point, the compression tact may be in the first or fourth cylinder.

When installing the time in this case, the tags of the upper dead point are first set, as described in the first case, and just as in the first case it is installed in the place of the trambler.

If, when you try to start the engine, it will not start, then you need to "deploy" the wires on the lid of the battle. To do this, we need to swap the wires of the first cylinder with four cylinders and correspond to the second and third cylinder places accordingly.

Ignition adjustment.

After starting the engine, it is necessary to adjust the ignition advance angle. There are two ways to adjust, with a strobe and hearing when driving.

When adjusting the ignition with the help of a strobe, the moment is controlled by the occurrence of the spark discharge and combining the tags of the upper dead point of the cylinder. Setting the moment of ignition by a strobeoscope is accurate, but designed for the reference engine and quality gasoline. Therefore, as practice has shown, it is better to set the moment of ignition on the rumor when the car is moving.

For installation on rumor on a straight level road section at a speed of 40 km / h. A sharp pressing of the gas pedal is performed. For harsh pressed A brief metal knock in the engine should be heard. Usually, in this case, the "knock of piston fingers" say, but in fact it is a knock skirt knock on the cylinder wall when the piston moves up when the fuel combustion and pressure on the bottom of the piston are excessive.

If the knock is missing, the ignition later, with a long-lasting knocking. This adjustment is recommended after each refueling, due to the inconsistency of the actual octane number declared.
