Generator VAZ 2110 8 valves injector characteristics

Design and parameters of the VAZ 2110 generator

To deal with the problems that the VAZ 2110 generator can cause, you should first understand what this unit is. A generator is a complex device responsible for the process of converting mechanical energy into electrical energy. This metamorphosis occurs during the operation of the crankshaft. When it comes into motion, it accelerates energy and transfers it to other elements of the system, as a result of which electricity arises. The VAZ generator is used to power the battery and other electrical systems, for example, the diagnostic system, ignition, as well as the on-board computer and much more. The device must be of high quality, meet reliability requirements, and guarantee uninterrupted operation of devices and systems.

Diagnostics

Due to the fact that the price of a new generator is “biting”, and maintainability is quite high, many motorists do it themselves with their own hands to eliminate generator malfunctions in the VAZ 2110, which I suggest you do with the help of these instructions:

Fault No. 1

In the case when the control light on the instrument panel indicates a discharge of the battery, and when checking with a tester in the electrical circuit of the car, the voltage does not rise above 13.2 volts, it is necessary to check:

Checking the voltage in the on-board network

1. Tension of the VAZ generator drive belt - tighten if necessary;
2. If the rectifier block valve is damaged, replace the entire rectifier block;
3. Diodes powering the exciting winding of the rotor - replacement of diodes or the entire rectifier block;
4. The outputs of the exciting winding coming from the slip rings for their unsoldering - solder the outputs/replace the rotor or the entire generator assembly.

It is also possible that the stator winding may short-circuit, break or short circuit to ground (in this case, noise from the generator appears in the VAZ 2110, the generator “howls”). These assumptions are checked using an ohmmeter; if a malfunction is detected, the stator or the entire generator must be replaced.

Malfunction No. 2

The warning lamp in the instrument panel also indicates that the battery is low, and the tester displays a voltage value in the vehicle circuit of at least 14.7 volts:

• The voltage regulator has definitely failed (the contacts of the “DF” output have closed with ground) - replace the regulator.

Malfunction No. 3

The generator noise is clearly audible in the VAZ 2110:

• If sounds such as howling and squealing are heard. When disconnected, the wires remain, and when the drive belt is removed, they disappear, this means that the bearings have failed - replace the bearings (the front one is replaced as an assembly with a cover);
• If, when the wires are disconnected, the noise disappears, this indicates a short circuit in the stator windings and their connection to ground—replace the stator/generator.

Also in this case, one of the valves may close, which threatens to replace the rectifier unit.

Malfunction No. 4

The warning lights in the instrument panel do not light up when turning the ignition key:

• Checking the “F19” fuse in the mounting block - replacement (it is advisable to find out the reason for the fuse failure);
• Open circuit in the instrument cluster “ignition switch” - check the integrity of the blue wire with a red stripe running from the mounting block to the ignition switch, as well as the orange wire running from the instrument panel to the mounting block;
• Malfunction of the ignition switch contact group - check the presence of a contact with a tester, if necessary, replace the contact group or the entire ignition switch.

Characteristics of the VAZ 2110 car

The VAZ 2110 car first entered the sales arena in 1996. At that time, it was a serious breakthrough, an original project that went beyond the standards adopted by AvtoVAZ in previous years. A new success story of the Volzhsky Automobile Plant begins with “ten”. Today this model is still popular, in demand and relevant.

First of all, thanks to its good technical characteristics and attractive appearance. Many note the reasonable cost of the model and the ability to carry out repairs themselves. The VAZ 2110 is a practical, quite simple, but not devoid of external aesthetics car. Over the years of work on the model, the manufacturer has released about a dozen quite successful versions - from basic to modernized, meeting all modern requirements for quality and functionality.

Under the hood there are two types of power units: gasoline carburetor and injection, 8- and 16-valve, with a volume of 1.5 and 2 liters. The simplest version can accelerate to a speed of 170 km/h, the luxury version is much faster and increases speed at 200 km/h. The main qualities of the car are lightness, dynamic performance, moderate fuel consumption, and maintainability.

The technical characteristics are not bad, but like any car, especially domestically produced, the VAZ 2110 often forces its owner to spend long hours in the garage doing repair work. One of the most common problems is the VAZ generator.

Design, principle of operation and possible breakdowns of the generator

The very first generators, which were once installed on cars, were created according to the collector principle. They were a simplified design, but were unreliable, short-lived and could not ensure uninterrupted operation. Therefore, for many years, designers puzzled over how to create a more complex type of device, the operation of which would not have such numerous flaws.

This is how selenium nodes appeared, and after them more advanced silicon nodes. This design ensured synchronous current supply; in addition, it turned out to be more compact, economical in materials costs and durable. The generator for VAZ is presented in a synchronous three-phase version. The presented device has the following design. The body is made of duralumin or other light alloy metals, which can significantly reduce the weight of the part.

Generator structure: 1 – casing; 2 – output “B+” for connecting consumers; 3 – noise suppression capacitor 2.2 μF; 4 – common terminal of additional diodes (connected to the “D+” terminal of the voltage regulator); 5 – holder of positive diodes of the rectifier unit; 6 – holder of negative diodes of the rectifier unit; 7 – stator winding terminals; 8 – voltage regulator; 9 – brush holder; 10 – back cover; 11 – front cover; 12 – stator core; 13 – stator winding; 14 – spacer ring; 15 – washer; 16 – conical washer; 17 – pulley; 18 – nut; 19 – rotor shaft; 20 – front rotor shaft bearing; 21 – beak-shaped pole pieces of the rotor; 22 – rotor winding; 23 – bushing; 24 – tension screw; 25 – rear rotor bearing; 26 – bearing sleeve; 27 – slip rings; 28 – negative diode; 29 – positive diode; 30 – additional diode; 31 – pin “D” (common pin of additional diodes)

How does he work

First, let's figure out how this device functions. His work scheme is as follows:

• The key is inserted into the ignition switch;
• The current goes to the excitation wires;
• The magnetic field created by the armature passes through the stator windings, and voltage appears at its terminals;
• When the armature rotation frequency becomes high enough, the self-excitation mode begins;
• The rectifier unit provided by the car design converts alternating current into direct current;
• The voltage regulator starts working when the crankshaft rotation speed changes, and the time for which the excitation wire is activated is adjusted.

The presented video will allow you to clearly get acquainted with the principle of operation of the generator.

Beginners are very interested in the most important question, without which there is no point in trying to fix something on their own - what is the generator used for.

First of all, the generator’s task is to provide energy to all electrically dependent equipment.

When the engine is started with the help of the battery, all the reins of power pass to the generator. He is now responsible for the operation of the audio system, air conditioning, power windows, etc.

The second, but no less important task of the battery is to recharge the battery. This happens when the engine is running. If it were not for the generator, the battery would not be able to provide power to all consumers for a long time; it would have to be charged regularly in the garage.

Scheme

Design Features

A standard generator for AvtoVAZ JSC cars consists of the following elements:

1. Back and front covers.
2. Air intake.
3. Brush holder.
4. Rectifier block.
5. Stator.
6. Capacitor.
7. Voltage regulator.
8. Pulley.
9. Rotor.

Some electric generators do not have a built-in voltage regulator. For example, this element is missing in generators for the VAZ-2101.

Malfunction No. 5

When the ignition is turned on and the engine is running, the warning lamp indicating a low battery does not light up, the remaining lamps in the instrument cluster work:

• Burnt-out control lamp/poor contact – replace the burnt-out lamp/clean and press the contacts in the seat;
• Open circuit “generator output “D” to the instrument panel” - check for continuity of the brown wire with a white stripe coming from terminal “D” to the instrument panel;
• Oxidation of contact rings, as well as hanging and wear of brushes - the brush holder assembly with brushes should be replaced, the contact rings should be wiped with a clean cloth moistened with a degreaser;
• Open circuit “DF terminal – ground” (damage to voltage regulator) – replace the regulator;
• Broken brush holder wire from terminal “D+” - restore contact;
• The positive diodes (valves) have closed - replace the rectifier unit;
• The leads coming from the slip rings to the rotor excitation winding have been unsoldered - solder the leads in place/replace the rotor/replace the generator.

This is where the list of the main malfunctions of the VAZ 2110 generator ends, I hope that this instruction will help you out at the right moment. As they say - no nail, no wand)))

Interchangeability of autogenerators

Interchangeability of generators for Lada cars is achieved if the following requirements are met:

• the main technical characteristics of the installed generator are not lower than those of the device being replaced;
• the gear ratio from the internal combustion engine to the generator is the same;
• the devices have similar electrical circuits;
• The new generator is suitable in terms of weight and dimensions and type of fasteners.

Most Russian-made automobile generators have a 2-leg mount. These fasteners are found on both covers. For equipment of foreign brands, installation is carried out using 1 paw, the fasteners are located on the front cover.

In order to correctly install and securely fasten a foreign generator in a car from AvtoVAZ, it is necessary to replace the bracket.

Removal and Installation Guide

Dismantling and installing a new device at home is not so difficult.

The connection diagram for the generator and the connection of all components is as follows:

1. First you need to turn off the power to the car's on-board network; to do this, open the hood and disconnect the battery.
2. Next, locate the generator assembly in the engine compartment and disconnect the excitation cable from it.
3. Using a 10mm wrench, you need to unscrew the nut that secures the two wires to the “B+” terminal. Once the nut is unscrewed, the wires can be disconnected.
4. Next, you need to remove the strap. If its condition is deplorable, then the belt needs to be changed to prevent it from breaking at the most inopportune moment. The strap should be replaced if it shows signs of damage, such as cracks or other signs of wear. Unscrew the mechanism adjusting screw, after which you can unscrew the fixing nut.
5. After these steps, you can remove the tension bar of the assembly.
6. Using a 13 mm wrench, you can unscrew the nut that secures the lower fastening of the unit.
7. Remove the screw and remove the device from the car. Further installation of the new unit is carried out in the reverse order.

1. Disconnect the device's excitation wire.

2. Remove the tension bar.

3. Use a wrench to unscrew the fastening and remove the assembly.

Price issue

If you need to buy a new generator unit, then you need to take into account that its cost varies not only depending on the manufacturer, but also on the technical characteristics. The more powerful the generator, the more expensive it will cost.

1. Model PRAMO 5102.3771 (price - about 6300 rubles)

2. BATE 3202.3771 (price - approximately 5400 rubles)

3. LKD 9402.3701 (price - about 5700 rubles)

About the current-speed characteristic

TLC is the dependence of the current supplied by a car generator to the on-board network on the rotor speed at a constant voltage. This parameter is calculated when the device is operated together with a charged and serviceable battery with a rated capacity of at least 50% of the rated current of the generator. The characteristic is calculated in the heated and cold states of the equipment.

Main consumer characteristics

1. Maximum current.
2. The magnitude of the operating voltage.
3. Rated power.
4. Gear ratio.
5. Efficiency
6. Dimensions and weight.

The main operating parameters, type and brand are usually indicated on the device label.

Some useful tips to extend the life of your generator

To ensure that your “ten” generator serves for a long time and does not present unpleasant surprises, use the following tips.

• At least once a month, check the condition of the device’s drive belt and its tension. If it is damaged, immediately take measures to replace it.
• Pay attention to the sound of the generator. If you hear a hum characteristic of failed bearings, replace them yourself, or contact a service center for this.
• Do not connect electrical appliances to the vehicle's on-board network that consume a current greater than the current generated by the generator.
• If the warning light on the instrument panel is constantly on, indicating that the battery is not charging, check the voltage regulator. If it fails, replace it.
• Do not expose the generator to water. It can cause a short circuit.

Criteria for choosing car generators

1. Maximum power . Power is one of the main characteristics of VAZ generators. It must ensure an uninterrupted supply of current and supply electricity to the battery, which is discharged due to the operation of regular electricity consumers at low speeds of the power unit. To perform basic tasks, the device must have the required power. The required indicator is indicated in the vehicle operating instructions.
2. Current strength . The factory generator installed in the car is not designed for a large number of additional consumers, but at the same time it has a certain reserve. If the autogenerator is “not enough,” then before purchasing a new device, first inspect the old equipment, clean the contacts, check the bearings, etc. You shouldn't use 120A generators in every car. First of all, it's expensive. Secondly, the current may be excessive. Such power-generating devices are installed in tuned cars with a powerful acoustic system.
3. Dimensions . Before purchasing, it is also worth comparing generators by overall dimensions. The device must be compact with high technical characteristics.
4. Noise level . The generator should not make too much noise during operation. This “disease” often affects high-power generators that are sold at a low price. One of the main reasons for the appearance of extraneous sounds (hum) is the poor quality of bearings, which wear out quickly.
5. Availability of guarantee . If there is a warranty, you can exchange a faulty device for a new one if it is defective.

Generator check

Problems with the generator set can be avoided if the condition of this unit is periodically diagnosed. Checking the functionality of the generator gives the driver confidence that it is working properly and there is no cause for concern.

You cannot test the generator by disconnecting it from the battery while the engine is running. This is fraught with power surges and short circuits . The easiest way is to contact a service station specialist to check the functionality of the generator on a stand. However, convinced “seven guides” have long adapted to checking the G-221A on their own using a multimeter.

For diagnostics, you will need a multimeter of any type - digital or indicator. The only condition: the device must work correctly in both AC and DC measurement modes.

Operating procedure

Two people will be required to diagnose the generator's functionality. One of them should be in the cabin and, upon a signal, start the engine, the second should directly monitor the multimeter readings in different modes. The operating procedure will be as follows.

1. Switch the device to constant current mode.
2. With the engine turned off, connect the multimeter first to one terminal of the battery, then to the second. The network voltage should not be less than 11.9 and more than 12.6 V.
3. After the initial measurement, start the engine.
4. When starting the engine, the measurer must carefully monitor the instrument readings. If the voltage drops sharply and does not rise to operating condition, this indicates the exhaustion of the generator's life. If, on the contrary, the voltage indicator is higher than normal, then the battery will soon boil away. The best option is that when you start the engine, the voltage drops slightly and immediately recovers.

Which generators are better to put on a VAZ?

Below are recommendations for different models of domestically produced cars.

VAZ - 2106

G-222 is a more powerful and stable self-generator compared to the standard G-221. It has a built-in battery charging relay and increased output (50 A versus 42 A), suitable for the “six”, provided that brushes from the G-221 are used or the connection diagram is changed.

VAZ - 2107

The simplest option for modernizing the electrical network is the G-222 device. The generator is installed in the VAZ-2107 without additional problems. This car will fit a device with a current of 55A from model 2108. The only modification that will be needed during installation is the use of an additional power relay.

VAZ - 2110

The standard generator of the VAZ-2110 is KZATE with a current of 80 A. It has a factory index of 5102.3771. Estimated mileage is 140,000 km. As alternative options, it is worth considering devices 94.3701 and 120 A. It is better to install the second generator on a VAZ 2110 with an injection engine in cars with a large amount of additional equipment, in addition to a DVR and a powerful sound system.

VAZ - 2112 and 2114

It is better to install a generator from Priora or Kalina with air conditioning in VAZ-2112 and VAZ-2114 cars. This device produces a power of 115 A, which is 35 A more than the factory equipment. The only difficulty that the owner of 2114 will encounter during installation is the need to replace the pulley.

As an alternative, you can consider an Eldix brand autogenerator with a capacity of 115 A. However, it is difficult to find spare parts for it, which will cause certain difficulties even with minor breakdowns.

Cars with injection engines are equipped with generators with an output of 80A. This is the standard model 94.3701. To increase power, consider the option with KZATE 9402.3701 90A, which is suitable for the type of fastener and has a similar pulley. If necessary, ensure the operation of a large number of energy-consuming devices.

Priora

A Russian or foreign-made generator can be installed in a Lada Priora car. One of the best options in terms of operational reliability is Bosch at 110 A. As a domestic analogue, you can consider KZATE 9402.3701-14 at 115 A.

For most cars from the Volzhsky plant, it is better to use Russian generator sets. Among the main advantages of domestic products, we note low cost, ease of maintenance and repair, and a large number of spare parts in stores. A better alternative is equipment from the German brand Bosch. It is better to avoid buying cheap Chinese electric generators.

Technical specifications

If the old generator fails, many motorists wonder which generator they should now replace the old one with.

There is no need to invent anything here. The most correct solution is to install the same generator as before, or a more powerful one.

Today, the VAZ 2110 provides for the use of three types of power supply devices:

1. Katek 5102.3771. The generator produces 80 Ampere power and its voltage is approximately 14V.
2. Katek 94.3701. This is a device with the same parameters. They are not seriously different.
3. Catek 120 amp. A generator that is more adapted to modern realities, when in addition to standard electrical equipment, motorists install many additional devices.

If you have a powerful audio system in your car, you use an electric pump powered by the car, as well as a number of other additional consumers, it is recommended to install a 120-amp unit instead of a standard 80-amp generator.

If we take into account the size of the devices, then we can distinguish between ordinary and compact ones. They have a certain difference in design. To be specific, the differences are in the following components:

• Brackets;
• Anchor;
• Excitation wire;
• Drive pulley;
• Number of mounting bolts.

But in reality this does not play a special role. After all, the structure of all generators used for the VAZ 2110 is the same. Therefore, let's look at the circuit and structure of this unit.
