Your question: How much does a VAZ 2101 engine weigh without attachments?

How much the VAZ-2101 weighs is affected by the wear of metal parts, the presence of additional body kit and gas equipment. It is worth noting that the vast majority of modern sedans are equipped with a monocoque body configuration. “Kopeyka” in this case is no exception. This design is a steel box, inside of which there is a compartment for passengers, driver and luggage. In addition, the body carries the working components and assemblies of the vehicle.

What kind of motor can be installed on a “penny” instead of the standard one?

One of the main types of car tuning is improving the car engine. VAZ 2101 engines are an unplowed field in this sense. Some craftsmen install turbines on them in order to increase power and traction characteristics, others change the crankshaft and bore the cylinders, and still others simply change the engine to a more powerful one. But here it is important not to overdo it, because the car body is designed for certain loads, exceeding which can seriously harm the entire car.

Among the popular options for replacement, it is worth considering only power units that are similar in design and performance. For a penny, without any problems, you can install a 1.6 or 2.0 liter gasoline engine from the same Fiat Argenta or Polonaise.

The engine from Fiat Argenta can be installed on any classic VAZ without any special modifications

You can try the same engine from Renault Logan or Mitsubishi Galant, if you install them together with a gearbox. But the best option is a power unit from subsequent modifications of VAZs. These could be VAZ 2106, 2107, 2112 and even 2170. The engines from these cars are suitable both in size and in mounting to the gearbox.

Useful information about the seven

VAZ 2107 body length

The weight of the “seven” is exactly 1030 kilograms. At the same time, the car body is the heaviest among all other parts and components (600 kg). Its assembly diagram differs in a standard, classic sequence for VAZs and includes the following elements:

• Front end parts along with fenders, complemented by reinforcements;
• Roof;
• The bottom is also well reinforced, especially in the front and rear;
• Sidewalls.

Each of the parts is made from a special type of steel, has its own ID number, a specific mold and casting pattern. So, the roof of the “seven” always has a thickness of 0.9 mm.

The body parts are combined with each other by welding. If elements, for example, such as the floor, bear a significant load, they are additionally strengthened by arc welding.

In addition to the main elements, the body of the “seven” also has attached parts called “tails”. These are the parts that can be connected with bolts and hinges to the main frame - bumpers, hood, and so on.

Regardless of the configuration, the VAZ 2107 has certain dimensions.

The body length of the VAZ 2107 reaches 4126 mm, the width is 1620 mm, and the height is 1435 mm.

Control dimensions or correct body geometry

It is not enough for the owner of the “Seven” to know only the standard parameters of the car. It will also be useful to study the control body dimensions of the VAZ 2107 or the points of the car’s frame, especially if the owner plans to improve the dynamics of the car by lightening the body.

The diagram below shows the main control dimensions of the VAZ 2107.

The same diagram shows how to check the control points of the body floor.

Control dimensions of the body of the VAZ 2107 floor

Control of the geometry of the body and the attachment points of the chassis and floor units is carried out on a special installation. This is a special type of machine designed for body inspection and repair. This is what he looks like.

VAZ 2107 body control dimensions and their correction

On such a machine, not only measurements are carried out, but also further editing of the body. The purpose of the operation is to recreate the original linear dimensions of the body.

ID VAZ 2107

On the “seven”, like other cars, individual technical information is indicated. It is presented in the table, which can be found under the hood.

IDs imply information not only about the car model. This contains detailed information about the body number and its weight.

VAZ engine malfunctions and their symptoms

No matter how reliable the power unit of the “penny” is, it can also sometimes be capricious. The main signs of its malfunction are:

• inability to start;
• unstable operation at idle, tripping;
• reduction in traction and power characteristics;
• overheat;
• extraneous noise (knocking, clattering);
• the appearance of white (blue) exhaust.

Naturally, any of the listed symptoms cannot clearly indicate a specific malfunction, so let's look at them in more detail in the context of possible breakdowns.

The engine won't start at all

If, when you turn on the ignition and turn the key to the position at which the starter is turned on, the latter works, and the power unit shows no signs of life at all, this may be evidence of failure:

• ignition coils;
• distributor;
• breaker;
• ignition circuits;
• fuel pump;
• carburetor

If such a symptom is detected, you should not immediately change any of the ignition system components or disassemble the carburetor. First, make sure that voltage from the battery is supplied to the coil, distributor, distributor, and spark plugs. After this, you can begin diagnosing the fuel pump and carburetor.

Unstable operation at idle

In this case, the malfunction can also be caused by problems in two systems: power and ignition. Typical breakdowns accompanied by this symptom include:

• failure of the carburetor solenoid valve;
• clogging of the fuel filter at the inlet to the carburetor;
• clogged fuel or air jets;
• violation of regulation of the quality and quantity of the fuel-air mixture;
• malfunction of one or more spark plugs;
• burning of the contacts of the ignition distributor, distributor cap, slider;
• breakage of the current-carrying core (insulation breakdown) of one or more high-voltage wires.

Here, as in the previous case, it is better to start searching for the problem by checking the ignition system.

Reduced engine power

The power unit may lose its power characteristics due to:

• fuel pump malfunction;
• clogged fuel filter or fuel line;
• violation of regulation of the quality of the fuel-air mixture;
• increasing the gap between the breaker contacts;
• incorrect adjustment of valve timing or ignition timing;
• wear of piston group elements.

If you detect a decrease in the power and traction characteristics of the power unit, first check whether the timing marks of the gas distribution mechanism match, and also whether the ignition timing is set correctly. Next, you should make sure that the gap between the distributor contacts is adjusted correctly. After this, you can start checking the fuel pump, filter and carburetor. If a drop in engine power is accompanied by thick white smoke from the exhaust pipe, the appearance of an oil emulsion in the air filter housing is a clear sign of wear or damage to the piston parts.

Overheat

A violation of the normal temperature regime can be identified by observing the behavior of the arrow on the temperature indicator located on the vehicle’s instrument panel. When overheated, it moves to the red sector of the scale. In more complex cases, the coolant simply boils. Under no circumstances should you continue driving with such a malfunction. This will inevitably lead, at a minimum, to burnout of the cylinder head gasket.

Engine overheating can be caused by:

• thermostat malfunction (blocking the movement of fluid through the cooling radiator);
• breakdown of the water pump (pump);
• low level of coolant in the system (depressurization, leakage of coolant);
• inefficient operation of the radiator (clogged tubes, external lamellas);
• broken radiator fan drive belt.

Having discovered that the car’s engine has begun to overheat, the first thing you need to do is check the coolant level in the expansion tank. Next, you need to determine whether the thermostat opens to a large circle. To do this, just touch the radiator pipes. With a warm engine they should both be hot. If the top one is hot and the bottom one is cold, the thermostat is faulty and needs to be replaced.

It is almost impossible to determine if the pump is faulty without dismantling it, so it is better to leave this option for last. But the performance of the fan is easy to determine. The “penny” has a permanent drive. Its impeller is driven by a V-belt from the crankshaft pulley. By the way, this belt also ensures the operation of the water pump, so if it breaks, two components of the cooling system will fail at once.

Extraneous noise in the engine

A car engine itself is a rather complex mechanism that produces many different sounds during operation. It is impossible for an uninitiated person to determine by ear a malfunction of the power unit, but a specialist, even without additional equipment, can tell you which sound is unnecessary and what kind of breakdown it indicates. For the VAZ 2101, the following extraneous sounds can be distinguished:

• valve knocking;
• knocking of main or connecting rod bearings;
• clatter of piston pins;
• loud rustling of the timing chain.

Valve knocking can occur due to increased clearance in the valve mechanism, wear of the valve springs, and wear of the camshaft cams. A similar problem is solved by adjusting the valves, replacing springs, restoring or replacing the camshaft.

The crankshaft main and connecting rod bearings may also make knocking noises. Such a malfunction may indicate low oil pressure in the system, increased clearance between the bearings and connecting rod journals, or severe wear of the bearings themselves.

Piston pins usually knock for one reason - incorrectly set ignition angle. Their knocking indicates that the fuel-air mixture ignites too early, which causes detonation in the combustion chambers. It is enough to “delay” the ignition a little by turning the distributor clockwise, and the problem will disappear.

The timing chain cannot help but rustle while driving, but an excessively loud sound is a sign of either stretching or a broken damper. Such a breakdown can be eliminated by replacing the damper or tensioner shoe.

Thick white exhaust

A serviceable engine practically does not smoke in dry weather. In frost or rain, the exhaust becomes noticeably denser due to condensation. This is absolutely normal. But if thick white (in some cases bluish) smoke comes from the exhaust pipe, regardless of weather conditions, most likely there is wear on the piston rings, and perhaps on the pistons themselves and the cylinder walls. In this case, the oil enters the cylinders and burns, and the oil that does not burn is expelled through the carburetor into the air filter housing. It is the burnt grease that creates that white smoke. In addition, when parts of the piston group wear out, exhaust gases can enter the lubrication system, creating excess pressure there. As a result, oil may even leak out through the dipstick hole. There is only one way out - a major overhaul of the engine.

But that's not all. White exhaust is also a sign of cylinder head gasket damage, in which coolant circulating in the cooling jacket enters the combustion chambers. This malfunction is almost always accompanied by exhaust gases entering the expansion tank. So, if you see white smoke, don’t be too lazy to look into the tank. The smell of the exhaust and air bubbles will point you in the right direction to find the problem.

Weight reduction

How much does the body of a VAZ 2107 weigh?

So, car developers have been fighting extra pounds for a long time. Success has been variable and it would be a stretch to say that any significant improvements have been achieved. As a rule, it is possible to lighten the body without affecting the standard linear dimensions of the VAZ 2107 body geometry using technologies that are innovative for a certain period of time. But innovations can be very expensive, and it is rarely possible to introduce them into general production.

Using the example of VAZ models, it happened like this: if one of the design bureaus managed to reduce the weight of the frame or internal combustion engine, then another bureau found and introduced devices that were enviably in demand at that moment into the car system, without which it was already unthinkable to imagine a modern vehicle. So we had to rack our brains again about how to reduce the weight of the car with new instruments and devices, and everything returned to normal.

Body dimensions of the VAZ 2107

So, if you take our “seven” and equip it with all the modern optional kit of an expensive foreign car, it will significantly lose dynamics and fuel consumption will increase.

I wonder how much the weight of a car like the “Seven” can be reduced? According to authoritative experts, the prudent line is within five hundred kilograms. It is no longer possible - instability will arise, and a strong push of the wind from the side can simply blow the car off the road.

In addition, you need to know that the total weight of a car that is too light will change dramatically depending on the number of riders.

An additional reason for changing the weight of the car is the new law established within the framework of European standards. Now the average emission of harmful substances into the atmosphere should not exceed 120 grams per 1 km of run. For every extra gram the owner will be fined 95 euros! What does mass have to do with it?

In fact, everything here is clear. The units of harmful substance released into the atmosphere are directly proportional to the burned fuel, and this indicator, as we know, directly depends on the weight of the car.

Body geometry VAZ 2107 dimensions

Modern metal production plants, or more simply, metallurgical enterprises today are beginning to introduce new technologies and innovative programs that involve the use of ultra-light materials for the manufacture of individual body parts. For example, doors are already coming out that are made of supercomposite materials, which are characterized by the same strength as metal ones.

The modernization also affects the wheels. It is difficult to compare anything with discs that are lightweight, elegant and infallible in terms of strength. They have been in high demand lately, and for good reason. True, their price is high, but it's worth it.

On the other hand, such disks will soon become a thing of the past. Innovative steel grades, such as DP600, can reduce the weight of the disc by 20 percent. And a biometallic steel disk, welded not by the usual method, but by laser welding from 2 different types of steel, generally weighs only 5.3 kg. As you know, the mass of aluminum is more than 6 kg.

Interesting solutions to reduce the weight of the VAZ 2107 car

Innovation is innovation, and many of us have to solve the problem with the weight of the car right now. Is it possible to change the weight of the “seven” on your own, thereby improving its dynamics and reducing fuel consumption. Of course it is possible.

How to lighten the body:

• Replace body panels with plastic ones where possible;
• Remove some elements of the interior and instrument panel;
• Replace glass with plastic;
• Remove stiffeners;
• Provide space for the battery in the rear luggage compartment;
• Make the hood and trunk lid out of plastic and replace the original ones (a great idea, but somewhat difficult to do with your own hands);
• Consider modifying the fuel tank (too heavy). You can replace it with a sports gasoline tank, which will reduce weight by as much as 10 kg;
• The stove, together with its components, also weighs a lot;
• Remove internal reinforcements in various non-load-bearing body parts. For example, you can do this on the hood or doors.

Reducing the weight of a car is one of the main ways to improve the dynamic performance of a car. Along with improvements such as increased aerodynamics or reforms in the field of improving the grip properties of the car with the road surface, reducing the weight of the car can radically change the overall performance.

Maintenance - regulations

A typical internal combustion engine device ensures that the replacement of consumables and maintenance operations are standard for the AvtoVAZ engine family, so the 21011 engine has the following maintenance regulations:

Consumables and spare parts for the engine are not in short supply, despite its discontinuation in 2006.

Tuning

• The tuning option with an increase in volume involves boring the cylinders and replacing the pistons with spare parts from older VAZ engines. Such work is somewhat difficult and can be expensive. It is necessary to bore the cylinders, replace the pistons and crankshaft. It is often easier to carry out an engine swap by installing an engine from a VAZ five or six.
• Installing a turbine can be considered solely in theory, since this tuning option leads to rapid failure of the VAZ 2101, the engine tuning of which was performed using a turbine and compressor. An engine with an installed turbine has a service life of about 20 thousand kilometers, while the power indicator in rare cases exceeds the 100 horsepower mark. This option is used only for cars participating in drag racing, where car owners do not care about the life of the car, but only the technical characteristics of the forced engine are at the forefront.
