Car ZAZ-1102 "Tavria" is a model of an especially small class (Fig. 2), which is fundamentally different from its predecessors. Each detail at Tavria is original in terms of layout and the most important technical solutions and corresponds to modern trends in the development of the automotive industry.
The front-wheel drive scheme, more modern, replaced the rear-engine one, which was previously used on all ZAZ cars. The power unit, consisting of the engine, gearbox and final drive, located in the front of the body, is located across the engine compartment.

This arrangement and the transfer of torque to the front wheels made it possible, with a relatively small size of the car, to create a fairly spacious cabin for 4 ... 5 people, to have a two-volume, easily transformable luggage compartment in passenger and cargo-passenger versions.
When transporting large luggage, the rear seat folds down and the useful volume of the trunk almost triples.
The body of the car is wedge-shaped, three-door, two-volume, hatchback type. Thanks to large side doors, curved side windows, anatomical front seats with infinitely adjustable backrest tilt and a wide range of longitudinal movement and rather wide rear seats, convenient entry and exit of passengers sitting in front and rear, convenient and comfortable seating and placement are provided.
The most important indicator of a car is its economy. It is achieved primarily thanks to an engine with a new combustion process, a high compression ratio, a two-chamber carburetor and a switched off fan in the cooling system. Affected here and the relatively low weight of the car, the new design of tires, five-speed gearbox overdrive gears, aerodynamically improved body shape.

Thanks to the front drive wheels and a rack and pinion steering gear, the "Tavria" has a fairly high directional stability, in general, the handling characteristics are noticeably improved, especially on slippery road surfaces. Front-wheel drive has created the basis for safer driving. It is this feature that contributed to the development and distribution of front-wheel drive vehicles.

Ignition system (SZ) vehicle includes many nodes and devices interconnected. One of the main components of such a system in ZAZ cars is a distributor. How to correctly install the Tavria distributor, what malfunctions are characteristic of this device and how to repair it, we will describe below.

In what cases is ignition installation necessary?

Tuning and repair of the ignition system

How to properly adjust the system operation? If you do not know how to set the ignition on Tavria, then we are ready to teach you this. The principle of setting SZ is to change the position of the valve in relation to the installation volute. Before you start tuning, you need to open the hood and look at this snail and distributor. Put marks on each element - this will allow you to put everything back in place if you make mistakes during the repair process.

The setup procedure looks like this:

1. Get behind the wheel, put the key in the ignition of your Tavria and start the engine.
2. Then, on a running power unit, you need to turn the switchgear slightly - first in one direction and then in the other direction. At this moment, you need to listen to how the engine works, whether the dynamics of revolutions has changed. You need to catch the moment when the engine speed will be at its maximum. Usually this is not a specific point, but a place in half a division on the site. The most optimal ignition is located in this range. If power unit your car works with detonation, then try to set a later ignition.
3. Then the distribution unit must be fixed in this position, and then diagnostics of the internal combustion engine operability in different operating modes.
4. When the distributor is fixed, you need to ride a little. Accelerate the vehicle to approximately 60 km / h, shift into fourth gear, and then slow down to approximately 40 km / h and again depress the accelerator pedal sharply. At this moment, detonation should appear, but literally for 1-2 seconds, no more. If so, then we can assume that half of the work is done.
5. In addition, you also need to check the power of the internal combustion engine. In the event that the engine power is not particularly high, then you can try again to adjust the distributor drive. In this case, you will need tweezers, as it will make this task much easier with its help. If you look at the distributor, you will notice that the cut under it on the drive is slightly offset to the side, so you should not make mistakes and install the drive incorrectly (the author of the video is a channel).

You can also adjust the distributor itself, the essence of this task is to change the level of tension of the weights, as well as setting the vacuum regulator. But keep in mind that to implement this procedure, you will need a special stand, which can not always be found even at a service station.

Device malfunctions and remedies

For what reasons the distributor may refuse to work and how can the situation be corrected:

1. The distribution unit has loosened, which led to the incorrect operation of the motor. Due to the loosened fastening, the lead angle could be lost, which in turn would lead to difficult starting, a decrease in power, as well as unstable idle speed. Fuel consumption will also increase. In this case, you just need to tighten the screw that secures the device using a wrench.
2. The high voltage wires are connected to the switchgear in the wrong sequence. This can lead to the fact that the internal combustion engine will not start at all or will start, but at the same time pops will be heard from under the hood, the car will go jerky. Open the service book and specify how the high-voltage wires should be connected, reconnect them.
3. Another malfunction is the broken mechanism cover. As practice shows, the breakdown site is usually clearly visible even with the naked eye. Due to breakdown, current leakage is possible, which contributes to malfunctions in the operation of the internal combustion engine. In this case, the only option would be to replace the cover.
4. Oxidation or destruction of contacts has occurred in the distributor cover. If we are talking about oxidation, then you can clean the contacts with a solvent, but if the problem is destruction, then the elements must be replaced.
5. The contact ember on the cover is worn out, while the motor will start with difficulty. Either the coal or the cover as a whole is replaced.
6. Hall sensor breakage. Such a malfunction will lead to the impossibility of starting the motor, the controller should be replaced. It is possible that there was a break in the wiring from this controller to the connector, then the device needs to be checked more carefully.
7. The upper bearing is worn out. Unstable idle speed... The problem is solved by replacing the roller with a centrifugal regulator, as well as a bearing device. Or the distribution mechanism will have to be changed completely.
8. The vacuum advance regulator is out of order. With such a malfunction, the transport power unit will not be able to pull the car uphill, the engine power will significantly decrease, as well as its throttle response. This is due to the fact that the regulator itself is used in order to set the lead angle a little earlier in a high load mode on the motor. The reason may lie in the lack of tightness of the body of this device or in the jamming of the nozzle from the carburetor connected to it. Also, the problem may be a defective pivot plate. The solution to the problem may be to eliminate the leakage problems or replace the failed components. In extreme cases, you can completely replace the regulator.
9. Problems in the operation of the centrifugal regulator. The symptoms will be similar. As for the reasons, it is necessary to check the springs of the weights, they could weaken or fail as a result of wear, the damper rings of the weights could also be lost, the weights themselves can jam. It is necessary to dismantle the distributor and replace the regulator itself, since its repair in most cases is impractical.

Do you know that the first domestic car, which became the hero of thousands of jokes, became the legendary minicar, created at the Zaporozhye Automobile Plant? If you quickly “flip through” the weighty volume of the complete collection of oral works of the Soviet people, then one of its most significant chapters will probably be titled “Anecdotes about the Zaporozhets”. "Hunchback" ZAZ-965 and "eared" ZAZ-966 front-wheel drive vehicles, the first of which was the ZAZ-1102 "Tavria".

The design of a front-wheel drive car at ZAZ began back in 1970. Dozens of options were sorted out by the designers, before deciding to settle on the only layout of the car - with a three-door hatchback-type body and with a transversely arranged four-cylinder liquid-cooled engine It should be noted that exactly the same layout became the main and when designing a front-wheel drive G8 at the Volzhsky Automobile Plant.

The car turned out to be quite interesting. The three-door body turned out to be quite strong, rigid and light enough, the trunk is spacious (250 liters), and if you fold the rear seat forward, its volume increased to 700 liters, which is even more than that of the VAZ-2108!

Under the hood of the car, in addition to the engine with the units serving it, the designers also placed a spare wheel. From this, the trunk has become more spacious, however, by today's standards, such an arrangement of the "spare wheel" somewhat reduces the level passive safety car, which "Tavria" and so is not too large.

Unlike all the "Cossacks", which had four-cylinder V-shaped air-cooled engines, "Tavria" was equipped with a MeMZ-245 engine - an in-line "four" liquid-cooled engine with an overhead camshaft, its working volume was 1,091 liters, and the power was 48 l s The engine is located in the engine compartment, in the front part of the body, transversely, with a backward tilt of 10 degrees Structurally, the engine is linked into a compact power unit, which also includes the clutch mechanism, gearbox and main gear The camshaft and cooling pump drives are produced by a flat-toothed belt ...

The clutch is dry, single-disc, with an elastic driven disc, equipped with a torsional vibration damper and with a diaphragm pressure spring. The clutch control drive from the pedal to the fork is cable.

The gearbox is mechanical, five-speed, and the fourth and fifth gears are accelerating gearboxes made in the same crankcase with the main drive. The gearbox case is cast from magnesium alloy and has external ribbing that increases its rigidity.

The main gear consists of a pair of cylindrical helical gears. The differential box is cast, cast iron. The front wheels are driven by two hinge shafts, each of which is a unit consisting of two joints of equal angular velocities - external and internal.

The front suspension of "Tavria" is a classic independent for cars of this type, such as McPherson ("swinging candle") with shock absorbers, each of which has a spring and a compression buffer, which are elastic suspension elements. By the way, this suspension at one time became the main one. for all front-wheel drive vehicles developed by the Soviet auto industry.

Rear suspension - semi-independent, lever, with a connecting cross member made in the form of a low-alloy steel beam, which is also a stabilizer lateral stability when the car is moving. Brackets are welded to the beam, with the help of which the suspension is pivotally attached to the body using silent blocks. Hydraulic shock absorbers - double-acting telescopic type - they are arranged in almost the same way as the shock absorbers of the front suspension.

A lot of unconventional solutions were used in the design of the machine. One of the main ones is the device of hub assemblies, in which diskless wheels are used, which made it possible to reduce the so-called unsprung masses.

The wheels themselves consist of stamped rings and rims welded to them with a landing diameter of 13 inches (330 mm) Each of the wheels is attached by three studs using three nuts with tapered bearing surfaces: the front ones to the hubs and the rear ones to the brake drum.

The reduction of unsprung weight is also facilitated by the original design of the front disc brakes, which have a disc-ring with an inner grip with a brake caliper. Rear wheel brakes are drum brakes.

The steering gear is a rack and pinion type, which has increased reliability and contributes to a good perception of the road by the driver.

The engine ignition system is battery-operated, non-contact, rated voltage 12 V It consists of a distributor sensor, a switch, a coil, spark plugs and high-voltage connecting wires The power supply circuit of the primary winding of the coil is interrupted by an electronic switch controlled by an electronic microswitch in the ignition distributor.

Ergonomics of the driver's seat - at the level modern cars of this class, and the design dashboard although it is extremely simplified, it is quite convenient for the driver to observe. Both on the highway and on city streets the car behaves well. Small dimensions, good visibility and quite decent maneuverability and throttle response allow the driver to feel on an equal footing with the owners of other cars, and the good stability of Tavria ”And a wide range of front seat adjustments allow him to travel long distances on suburban highways in one go without fatigue.

Thanks to the leading front wheels, the "Tavria" has a sufficiently high directional stability and good handling characteristics - even on slippery roads.

One of the main elements of the active safety of the car is a dual-circuit brake drive with a diagonal line of pipelines Passive safety is ensured by the body structure, thanks to which, in an accident, the impact energy is absorbed and the specified space in the cabin is maintained. bumpers made of impact-resistant modified polypropylene, crash-proof steering column and three-layer triplex windshield.

It is interesting that "Tavriya" inherited quite decent cross-country ability from the "Cossacks" - it behaves well on a country road thanks to high ground clearance, small overhangs and a smooth bottom.

When the "Tavria" moves on country roads, the engine consumes only 4.8 liters of fuel per 100 km (at 90 km / h), and on city streets - 7.2 liters. By the way, the maximum speed of the "Tavria" is 132 km / h, and acceleration time of the car to a speed of 100 km / h - 24 s.

Serial production of the ZAZ-1102 model began in 1987, and six years later the plant mastered another modification of the car, called the ZAZ-1105 "Tavria" (later it was renamed "Dana"). the same power unit and the same chassis.

Serial production of the next incarnation of "Tavria" - the hatchback ZAZ-1103 "Slavuta", designed with the participation of specialists from the Korean company Daewoo, began in 1997. Although the machine received a new 1.3-liter engine with a capacity of 63 hp, its design compared with the ZAZ-1102 has not changed too much True, unlike the "Tavria", in standard equipment car modification "luxury" (ZAZ-110308-01 "Slavuta") includes vacuum amplifier brakes, central locking, front power windows, heating rear window, a radio tape recorder and four speakers, as well as an air duct for heating the legs of the rear passengers.

In profile, the car can be mistaken for a sedan, but behind is not the trunk lid, but the fifth door, so formally "Slavuta" is still a hatchback (sometimes such hybrid bodies are called a liftback).

The capacity of the cabin has not changed in comparison with Tavria - four adults in Slavut are also cramped, but in the 2 + 2 version (two adults and two children) the car is quite comfortable.

The instrument panel has hardly changed and the speedometer readings are still easy to read. However, the driver still lacks a tachometer. True, the appearance of the so-called econometer, which allows you to choose the most economical pace, is encouraging.

The gearbox ratios are well matched, which allows the car to accelerate to "hundreds" in 17.1 s. Interestingly, after 80 km / h the car "asks" to engage the fifth gear. maximum speed, then, according to the testers, it is better not to move on the 150 km / h declared by the plant - already at 145 km / h a light car literally starts to slide over the road.So the maximum that you can afford on a decent track is 120 km / h It is at this speed that the econometric needle indicates the optimal fuel consumption - about 6.5 l / 100 km.

If the reader is faced with the question of purchasing "Slavuta", then, as experts say, you need to think hard here. The fact is that this car was designed very well, but the assembly After a run of 1500 km after purchasing the car, the owner will have to carry out TO-1 - the car needs broaching of the chassis, cylinder head, valve adjustment, oil change in the engine and gearbox and replacement of air and oil filters - all this will cost the buyer dearly However, in the future, repair work for any technically savvy motorist will not turn out to be unnecessarily difficult - the car is very simple and maintainable. Perhaps it is quite difficult to find spare parts in Russian stores. However, the prices of the Slavuta and the VAZ classics are quite comparable, and the ZAZ-110Z, compared to the VAZ-2105, does not look more modern than an example.
