Design and technical characteristics of the VAZ 2105 injector: dimensions, tank volume, fuel consumption

Production of the VAZ 2105 began in 1980. With its appearance, the “five” was fully consistent with the fashion trends of passenger cars of the early 80s. Thus, the body has straight lines with aluminum bumpers, the headlights are voluminous and rectangular. In terms of maintenance, the VAZ 2105 is one of the most inexpensive models.

The ancestor of the second generation classic lived on the assembly line the longest life of all the models that trace their history back to the VAZ-2101. This brought interesting metamorphoses in its role in the history of the domestic automobile industry. All models from the VAZ-2101 to the VAZ-2107 are very similar to each other and have a common ancestor - the Fiat 124. And yet we can distinguish the first generation (relatively speaking, all models with round headlights) and the second (with rectangular ones).

Dimensions and specifications

Regardless of the configuration, the VAZ 2107 has the following dimensions:

– length – 4126,

– width – 1620,

- height - 1435.

- curb weight (how much is the weight of the car with equipment and materials) - 1030 kg,

- total weight (how much does a loaded car weigh with passengers and cargo) - 1430 kg

A motorist needs to know not only the standard parameters of his car, but also the control dimensions.

Control dimensions (points) are usually necessary when restoring a car after an accident. If you buy a used car, knowing these control dimensions, you can easily find out whether the car has been in an accident. This geometry will help in restoring the body, as well as other important parts.

The main control dimensions are described in detail in the diagram below:

The linear dimensions are clearly defined by the following diagram:

A person knowledgeable in design will notice that the difference is not only in the shape of the headlights: the body of the “five” is more angular (to suit the fashion of the second half of the 1970s), curved surfaces have become flatter, and the edges have become sharper. The overall proportions and even the longitudinal tilt of the body have changed. Most of the car's components were revised, so the unification of VAZ-2105 parts with previous models (2101, 2102, 2103 and 2106) is much less than with future ones (2104 and 2107). It was assumed that the VAZ-2105 would become a new sedan of the “norm” configuration (that is, a replacement for the VAZ-2101).

Changes in the fate of the “five” began when the country moved from a planned economy to a market economy. Unable to master new models, VAZ was forced to beat prices in order to survive - and here the model played an important role. Thanks to its manufacturability and investments in development that were “recaptured” a long time ago, it became one of the cheapest cars in Russia (and in the world), and when SeAZ discontinued the Oka, it became the cheapest.

The quality of production has seriously declined, but at all times it was possible to buy spare parts for a car of any quality at any price - from penniless basement ones to expensive imported ones, so each car enthusiast himself chose his own level of care for the car. The car was easily repaired by the owners, and the prices for repairs in services were and remain lower than for any other car.

The VAZ-2105 has become invincible in state competitions (traffic police fleet, post office, support programs for rural teachers, doctors), where price plays a major role. The equipment has been simplified to the maximum so that, God forbid, another manufacturer does not cross the road - in the “five” of recent years there is not even a daily mileage counter. Due to its low cost, the car was in demand in the West for some time and was even assembled in the UK. After the 2008 crisis, the program for recycling old cars again caused an explosion of interest in the “five” and forced VAZ, which was thinking about stopping its production, to extend it for another 2-3 years.

To meet the more stringent economic standards of the 21st century, the car was equipped with an injection engine. And in order to modernize the appearance, the VAZ-2105 car began to be offered in metallic colors. From an aesthetic point of view, this is a mistake: the design of the “five” was created in those years when there were no metallic paints, and metallic creates an unwinning play of glare, light and shadow. However, buyers liked this option. The end of the “five” came when the decision was made to transfer its production to IzhAvto. The plant re-evaluated the profitability of production and came to the conclusion that in the process of modernization, the VAZ-2105 practically ceased to differ from the VAZ-2107 and it was more profitable to produce one model. They left the VAZ-2107. This is an interesting fact: the VAZ-2106 and VAZ-2105 lasted on the assembly line for almost the same time, 30 and 31 years, respectively. However, the VAZ-2106, the last representative of the 1st generation of Zhiguli, had a circulation of more than twice as much.

Body features, dimensions of the “five”

The body of the VAZ 2105 is a one-piece supporting structure of the sedan type. It is designed in such a way that when the front or rear of the vehicle collides with an obstacle, the impact force is absorbed as a result of deformation of body parts. This is necessary to maintain an injury-proof space for the driver and passengers. All body parts are made of low-carbon steel sheet with a thickness of 0.7 mm by stamping, for the floor and roof - 0.9 mm, for load-bearing elements - racks, side members - 1.5 mm.

In order to reduce noise and enhance protection against corrosion, the underbody and wheel arches are covered with plastisol, and hidden cavities - sills - are treated with an anti-corrosion compound of the NGM-ML type. The 5's bumpers really did their job. Made of durable aluminum alloy with a rubber buffer, mounted on tubular elements, they adequately withstood the impact, protecting the body from deformation.

Dimensions of the fifth model:

All modifications of the VAZ 2105 have similar dimensions, including the “Lux” version 2107 and the station wagon 2104.

You will find the exact same number in the trunk.

Basic faults

1. The engine does not start. In this case, several options for eliminating the breakdown are possible. The first thing you need to check is the presence of fuel in the VAZ 2105 carburetor. If there is fuel, you should carefully examine the fuel pump. It may become clogged or be completely faulty. If everything is fine with the pump, pay attention to the ignition system. If there are no problems with it, then the reason is a leak in the carburetor.
2. The engine runs unevenly or begins to stall at idle. There may be several reasons for this problem. These include: incorrect adjustment of the idle speed in the engine, malfunctions in the carburetor, damaged drain pipe, worn gaskets, damaged pipeline hose, incorrectly set gaps, breakdown of the ignition system.
3. The VAZ 2105 engine cannot develop full power. The reasons are as follows: the carburetor throttle valve is not fully open, the air filter is clogged, the ignition system is faulty. You need to check all these points to fix the problem.

These are the main malfunctions of the VAZ 2105 engine. It also does not hurt for a car enthusiast to remember how the car should be operated correctly.

At first, you should not use the maximum speed limit of the car. The driver needs to get used to driving the VAZ 2105. If you choose the wrong speed of the car when driving, you risk damaging the front suspension elements and causing the rear axle beam to bend. Also, at maximum driving speed, rapid tire wear is possible, and increased body vibration will lead to instability of the car.

Diesel modification

In 1999, in Tolyatti, a modification of the VAZ-21045 began to be produced in small series, with a VAZ-341 diesel engine produced by Barnaultransmash with a volume of 1.52 liters, with a high-pressure fuel pump from Bosch. Since 2005, it was planned to install a more powerful version of a 1.8 liter diesel engine, but these plans remained unrealized. The diesel modification was distinguished by a significantly higher cost and lower power of the power plant, despite the fact that in these years diesel fuel was noticeably cheaper than gasoline, the economic feasibility of purchasing this version was in doubt. In 2004, production of the VAZ-21045 was discontinued, and the remaining uninstalled diesel engines, in the amount of 500 pieces, were completed in a batch of the new modification of the VAZ-21055.

The main difference between these versions was that in the diesel version the main gearbox was replaced from 3.9 to 4.1, and there was additional sound insulation in the engine compartment, since the diesel engine made more noise during operation than the gasoline version. By replacing the front springs, the front suspension was strengthened. There was a new button on the dashboard that was responsible for heating the fuel filter, and an indicator for heating the glow plugs also appeared.

The Volzhsky Automobile Plant produced many classic and working models for private use. And if production began with sedans, then the first station wagon was the “four”. The new body and new capabilities of the model immediately attracted the attention of buyers.
