Body weight of VAZ 2107: reducing the weight of the car with your own hands

A car's directional stability and handling are also directly related to its weight. The peak of popularity of large, heavy cars abroad occurred in the 50-60s of the last century. Then the auto industry produced truly gigantic cars. For example, the Cadillac Eldorado modification 8.2 weighed almost 3 tons. Agree that for such a weight, an appropriate makeweight is needed.

But as time passed, it became clear that in order to further develop and improve the most important characteristics of the car, it was necessary to resort to reducing its overall weight. And if we compare the middle of the last century and today, cars have lost half, or even more, of their own weight. Plastic, carbon fiber reinforced plastic, light metals - all these innovations have made it possible to make the weight of a passenger car significantly lower.

Of course, for lovers of everything big and heavy, cars are produced that look like steamships that drink buckets of gasoline, but this is rather an exception to the rule.

Weight of passenger cars in tabular format

We present to your attention a table that shows the weight of the car by brand.

Thus, it turns out that if we take, so to speak, “in general for the hospital,” then the average weight of a passenger car is approximately from 1 to 1.5 tons, and if we talk about SUVs, then the whole weight already shifts from 1.7 tons to 2. 5 tons.

Differences between cars of recent years [edit | edit code]

In cars of the last years of production (under the state car recycling program), in order to minimize the selling price, the maximum cost of elements was made relative to previously produced equipment. What we noticed: there are no ashtrays in the rear door trim; interior door handles are made of molded hard plastic (instead of rubberized material); There are no clothes hooks on the ceiling handrails; one weak and capricious sound signal “tablet” was used, instead of two “horns”. The 2010 car was not equipped with a pump. In addition, changes affected the appearance of the “seven”. Instead of a flat trunk lid, a lid with stamping from a VAZ-2105 appeared, and the plastic molding at the bottom of the body disappeared. They refused to paint the door pillars and frames black, and they abandoned the chrome-plated external door handles. Headlight washers and cleaners were no longer installed on cars of recent years of production.

Features of car recycling

Before you scrap your car, you should familiarize yourself with the principles of this procedure. The average weight of a vehicle is 1000 kg. If the entire car can be recycled, the collection point will deduct 30% for clogging. The latter includes all non-metallic elements, pollution, etc.

Let's consider how much a car for scrap metal weighs using the example of a VAZ 2105. The weight of the latter is 955 kg. Thus, taking away the blockage, we get about 660 kg. You should also take into account the price of scrap, which differs depending on the city. As a rule, in megacities, the number of rubles received for a car will significantly exceed the amount earned in a similar organization in a small locality.

Before calculating the profit from a scrapped car, you need to take into account transportation costs. If the car is a pile of metal, you need to take care of a tow truck. If there are spinning wheels and functional steering, the car can be transported in tow. Then, this expense item will not be so significant. Therefore, in order to calculate how much a Zhiguli costs when scrapped, it is not enough to know how much a VAZ 2109 or 21099 weighs for scrap metal (915 kg). It is necessary to take into account the features of recycling and the requirements of collection points. It would be useful to know the average cost of scrap metal in the region. Additional awareness will allow you to avoid fraud on the part of unscrupulous receivers.

Despite the fact that disassembling a car is a labor-intensive procedure, many owners still decide to take this step. Thus, you can sort ferrous and non-ferrous metals and hand them over separately, removing the good parts. From an economic point of view, the procedure will be justified.

Let's consider how much a VAZ 2106 weighs for scrap metal based on individual significant structural elements:

• body – about 300 kg;
• bridge – 52 kg;
• motor – 140 kg.

It should be noted that dismantling machine parts requires a lot of time and certain skills. In the absence of the latter, it would be more rational to recycle it entirely.

Wiper sizes

Factory wipers on the VAZ-2107 are 33 cm (13”). Despite the fact that 14” and 15” wipers are suitable for this car model, factory ones are considered the best option, since the motor is designed specifically for them. Despite the improvement, all glass on the VAZ-2107 remained the same size:

• wind – 1440×536×6;
• rear window – 1360×512×5;
• front door glass (pivot) – 346×255×5;
• front door (lowering) – 503×422×5;
• rear door (lowering) – 543×429×5;
• rear door glass (fixed) – 372×258×5.

All geometry control points also remained unchanged. They can be found on the drawings that come with the car. The standard dimensions of the aluminum stove radiator are 200×174×42. It is also suitable for other models, such as VAZ-2101, VAZ-2103, VAZ-2105.

Fuel quality

In the case where such a problem arose shortly after refueling and it is not relatively hot outside. Almost one hundred percent the root of evil lies in the quality of the fuel poured in. If low-quality gasoline was poured into an almost empty tank, such symptoms appear almost immediately. In this case, to compensate for the negative effect, you can add high-quality fuel to the tank and thus dilute the surrogate. Then you can continue driving on this “fuel” until it is completely used up.

If this method does not help, you will need to drain everything in the tank and completely flush the fuel system. Flushing the system is performed as follows. Initially, all fuel is completely drained (including from the fuel lines). The gas tank is removed and washed, and the lines are purged. Next, you need to completely download all the gasoline from the fuel pump and rinse it too. The carburetor is rebuilt and purged. Also, do not forget about timely replacement of gas filters. If they become clogged, fuel may not fully enter the engine and cause a breakdown.

Fuel system malfunctions

The quality of fuel in our country leaves much to be desired. Due to high prices for fuel and lubricants, many drivers are trying to save money. They buy fuel by hand, at small gas stations. You shouldn't expect high quality from cheap gasoline. For this reason, if the car moves jerkily, then you need to pay attention to the fuel supply system:

1. Most often, the car starts to move jerkily if you have poured low-quality fuel into the tank. If at the time of refueling the tank was almost empty, then you will notice the problem almost immediately after replenishing the fuel supply, and the exhaust gases will become very dark. If there was already gasoline in the tank, then the car will cover part of the distance calmly. The confusion can only be eliminated by using high-quality fuel; you can dilute gasoline with another, high-quality one. If this does not help, then you need to flush the fuel system.
2. If you have not used your car during the winter, then in the spring you may feel jolts when accelerating due to condensation in the gas tank. As a rule, the engine does not stall for long.
3. The problem can arise due to untimely replacement of the fuel filter. If there is excessive clogging, the fuel pump will not operate smoothly. The situation can be corrected by replacing the filter with a new one.
4. As the engine and ambient temperatures rise, the fuel pump creates “vapour locks”. You can only get rid of them if you reduce the temperature of the pump. Wet the cloth and place it on the unit.

Problems sometimes arise not only for economical drivers. Often due to violation of storage rules, at some stations of large networks you can also get fuel diluted with water or garbage. Water is denser than gasoline and enters the cylinder block first. Because of this, the car begins to twitch. Debris clogs the filter very quickly, change it promptly to keep your car running smoothly.

Performance indicators

The maximum speed to which a standard VAZ engine 8kl and 16kl could be accelerated.

Hello friend, judging by the title, you probably immediately remembered your childhood, when we determined the coolness of a car by its maximum scale on the speedometer and looked into the car windows to see the maximum numbers on the speedometer and evaluate how cool the car was. Or faster and better than another.
But this article is not about that. Today I would like to talk about what the maximum acceleration speed of standard VAZ engines, the popular 1.6, can be. The difference is only in the number of valves, 8 or 16. And the results for maximum acceleration are very impressive, considering that this is a VAZ. And the engines are completely stock, without any modifications . And so there are two cars. VAZ 2114, engine 1.6 8 cells. Second VAZ 2112 engine 1.6 16 cells.

The first VAZ 2114 is a completely standard engine with a volume of 1.6 8 valves

. Compression in all cylinders is 12 plus, minus 0.3 kPa. Acceleration on a flat road was 165 km/h, then the car stalled and no longer accelerated. There were two speedometers and an on-board vehicle; on the on-board vehicle it was 166 km/h.

Now we tried to accelerate a VAZ 2112 along the same route 1.6

16 valves

.Engine compression is approximately equal to 11-12 kPa in all cylinders. The acceleration was 200 km/h and 5,000 thousand revolutions, the car didn’t want to accelerate any further, and the speedometer ran out, and so did our nerves, driving the VAZ at 2,112,200 km/h was another feeling.

But no matter what the speed, the body of this car is not designed for such speeds. Having accelerated these cars to such speeds, it felt like we were about to take off, and the hum in the cabin was like an airplane engine.

Facing panel (apron) and front bumper

The facing panel or front apron on the “seven” plays more of a decorative role. But besides giving a stylish appearance, an apron also provides many benefits. In particular, thanks to it, during rain, water does not fly directly onto the windshield, but is cut off by this element.

The apron is located directly under the bumper and is a flexible shield that also serves to prevent damage to the front of the car from splashes from under the wheels.

This structural element of the body has special holes for the front bumper brackets and the radiator grille (the latter is attached to it). The apron, due to its “extreme” location (bottom and front), becomes vulnerable to impacts and corrosion. Connected to the body by spot welding.

The design of the "seven" apron must be thought out carefully and correspond to the shape and geometry of the entire car body, otherwise it will simply vomit at high speed. In addition, non-compliance with geometry and design will lead to increased fuel consumption at high speed.

The price for a front apron for a VAZ 2107 individually starts from 600 rubles. The part may be of different workmanship, have a different color and different design features.

Front aprons, sold as a separate element of body decor, come with special mounts to the bumper. As for the original Semerovo ones, they are welded, as mentioned above, to the car body.

The rear apron is also required and must have special fastening plates that ensure its immovable condition and prevent it from coming off on the road.

Front bumper

The bumper is not only designed to retain the energy of a frontal impact first, but also plays a significant role in the exterior design of the Seven. In other words, this is a beam located in front and protects the body from damage in minor collisions.

Thanks to modern synthetic-based materials, bumpers have become much lighter and more beautiful than they were before. Thus, elegant bumpers with bent edges also serve as spoilers, increasing the downforce of the car.

The front and rear bumpers on the VAZ 2107 are made of plastic or thin metal and have chrome trim. They are mounted using special brackets.

The front bumper is equipped with a platform for attaching a license plate and for this reason is 5 cm wider than the rear one.

Today, the owner of the “Seven” is offered three options for bumpers for the VAZ 2107: plastic, plastic with chrome lining, and with brackets for fastening. The price starts from 600 rubles.

Front bumper tuning

Modernizing the front bumper of the “Seven”, first of all, means improving the appearance. To be honest, the factory bumpers of the VAZ 2107 family look, to put it mildly, fake. They do not carry any visual, or even more importantly, high-quality functionality.

The implementation of the idea of ​​tuning the bumper on a VAZ 2107 (the rear one is also possible) consists in strengthening it with a metal profile of an L-shaped section. In addition, to give a more aesthetic appearance, the part moves slightly from the body.

You need to work with the bumpers removed. Here's what to do:

• Place the pre-prepared reinforcing corner to the bumper and mark the mounting holes, and then drill them in the profile;
• The lower part of the profile bends forward. This creates a fastener for the lower bumper bolt;
• First, the amplifier is attached to the body, then the bumper is attached to it.

As a result, we get a massive bumper that is not afraid of light and medium impacts and looks much more impressive in appearance than the factory one.

Injector maintenance

Since the injection power system is quite complex, during the operation of the car there is a need to eliminate failures and failures. You can service the car yourself if you have a detailed diagram. In particular, engine management systems:

To troubleshoot you need:

By comparing the measurement results with operating parameters, you can easily identify an electrical circuit operating with deviations. And only then, when analyzing it, detect a non-working device: sensor or wiring.

Methods for solving breakdowns

Now that the main faults have become known, you can move directly to methods for solving the problem. Since the motor has a fairly simple design, even a novice car enthusiast can fix the problem. So, let's move on directly to the consideration of repair operations.

Floating speed

Why do I fluctuate engine speed? This is due to the combustion of fuel in the cylinders. If we consider this issue at idle speed, then often the reason lies in the carburetor. The idle speed control is faulty or the air-fuel mixture supply is incorrectly adjusted. Often, in order to eliminate the effect, motorists rebuild the carburetor and replace the idle speed screw.
