Engine for VAZ 2107 injector how many horsepower

History of creation [edit | edit code]

The VAZ-2107 is a modified luxury version of the VAZ-2105, which, in turn, traces its origins to the Fiat 124, a subcompact family sedan from 1966 (winner of the 1967 European Car of the Year). The VAZ-2107 was exported under the names Lada Nova, Lada Riva, Lada Signet, Lada 1500

. [3]

From 2002 to 2012, the VAZ-21070 (modification of the VAZ-2107) was produced in Ukraine (LuAZ, ZAZ and KrASZ [4]). In May 2008, the assembly of LADA 2107 was launched at Argun in the Chechen Republic [5]. Since March 2011, the production of LADA 2107 has been mastered by the Izhevsk Automobile Plant.

Characteristics of the VAZ-2107 engine

One of the main characteristics is the engine power of the VAZ-2107, which can vary depending on the modification of the car. For example, since its appearance on the domestic market (1976), three models with carburetor engines have been produced:

• VAZ-2107 1.5: engine capacity 1451 cm3, power 72 kilowatts;
• VAZ-21072 1.3: volume 1290 cm3, power 64 kilowatts;
• VAZ-21074 1.6 l. s: engine capacity 1569 cm3, power 74 kilowatts.

In addition, the manufacturer has released two modifications of the car with an injection power unit - 2107i 1.6 (engine power 70 kilowatts) and 1.6MT (73 horsepower). It is impossible not to mention the 21073 1.7 model with central injection of the air-fuel mixture. This type of “seven” uses AI-95 gasoline as fuel (other models use AI-92), has an engine capacity of 1689 cm3 and boasts the highest power of 76 horsepower.

Weight reduction

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.

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.

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.

Features of operation and maintenance

• Fuel selection

It was said earlier that many drivers cannot decide on the type of fuel used for their engine on the VAZ 2107. And if with AI-92 everything is simple, since its composition is very similar to AI-93, then with AI-95 everything is not so smooth.
Increasing the octane number leads to an increased risk of valve burnout, but gives a small increase in power. The engine begins to run smoother and more stable.

But the designers still took into account the possibility of using AI-95 gasoline. You just need to correctly set the ignition timing on your car (if you have a conventional carburetor engine) or reflash the engine control unit (if your VAZ 2107 engine is fuel-injected). But usually even this is not required. Engines of this brand are very durable and not picky about the type of fuel (within reasonable measures).

• Change of oil

Changing the oil on any engine must be approached with the utmost seriousness. Poor quality oil can lead to not very pleasant consequences, such as accelerated wear of main components and assemblies.

The ability to select oil is a real skill. Taking well-known brands is not always safe, since you are very likely to come across a counterfeit from dishonest companies. At best, you will not receive the positive qualities that this company has. At worst, you will have to carry out major repairs.

You shouldn't buy unknown brands either. In this case, you are buying a pig in a poke. You can buy oil that is of a quality that is not inferior to expensive analogues, or you can end up with expensive repairs. It is best to buy oil in specialized stores, where you can get at least some explanation and compensation.

Another important parameter is the oil class according to the international nomenclature. True, everything is simpler here. You just need to take the oil that the manufacturer himself recommends.

The manufacturer (AvtoVAZ) for VAZ 2107 engines and other models with this type of engine recommends:

• 5W-30;
• 5W-40;
• 10W-40;
• 15W-40.

You need to take about 4 liters of oil. When changing 3.5 liters of oil is usually enough. It’s better to carry the rest with you in the trunk, since oil consumption in this engine leaves much to be desired.

• Changing the oil in the VAZ 2107 engine

The procedure itself is quite simple and should not raise any questions. It is better to change the oil on a VAZ 2107 in the warm season.

1. First you need to start the car and warm it up to operating temperature. Then turn it off and let the oil fall back into the crankcase. This will take about half an hour. During this time, we prepare a receiving container with a volume of 4-5 liters, as well as new oil, a watering can and a hose.
2. Use a special wrench to unscrew the plug on the crankcase and wait for the old oil to drain out.
3. If you change the type of oil or brand, you must also take flushing oil, which will clean the engine of the remnants of the old one. We pour it in the same way.
4. Then we tighten the crankcase cover and fill in new oil through the neck on the cylinder head. We measure the level with a dipstick. It should be somewhere between the MIN and MAX marks. Please note that oil is not water and it cannot quickly sink into the crankcase, and therefore after a short stop the oil level in the crankcase will rise a little more.

Usually, along with changing the oil, the oil filter is also changed. It's even simpler here:

1. We unscrew the old one using a special tool (you can also use an ordinary rope), lubricate the o-ring of the new filter with oil and screw it in place of the old one.

• Adjustment of valves

Adjusting valves is a rather complicated process and requires certain skills and tools. Actually, it is advisable to entrust the valve adjustment itself to competent specialists, but if you want to do everything yourself, then this video is for you:

Major repairs and maintenance

If valve adjustment can be done at home, then major engine repairs should only be entrusted to specialists.

During a major overhaul, all components and assemblies of the VAZ 2107 engine are checked for serviceability. They will check for you:

1. Valve condition, adjustment;
2. Chain, chain tension;
3. Condition of oil seals, valve stem seals;
4. Geometry of the cylinder block;
5. Condition of the pistons, crankshaft, pins, connecting rods;
6. Wear of compression rings;
7. Condition of the oil pump and coolant pump.

If damaged, the part will be replaced. The cylinder block will be bored out, which will increase the combustion chamber and working volume. After this procedure, the car will be run-in for several thousand kilometers.

Typically, running-in lasts 5-10 thousand km. At this time, it is not advisable to give the engine heavy loads. After completing this procedure, your engine will make you happy.

Malfunctions

1. Engine won't start

2. Knock of the main bearings of the crankshaft Usually a dull, metallic knock. It is detected when the throttle valves are opened sharply at idle. Its frequency increases with increasing crankshaft speed. Excessive axial clearance of the crankshaft causes a sharper knock with uneven intervals, especially noticeable with a gradual increase and decrease in the crankshaft speed.

Engine tuning

The most popular types of tuning for engines of this type are increasing the displacement, replacing the camshaft, installing a zero-resistance filter and direct-flow exhaust.

The most effective way (and the most expensive) is to install a turbo kit.

• Increase in working volume

The design of the VAZ 2103 engine allows for a good increase in displacement, since its cylinder block is almost identical to the VAZ 2106 engine block. And when this block is bored, it can be made to fit the piston and rings of the VAZ 2106 engine.

Thus, we get an increase in displacement, which increases fuel consumption and power. If even this is not enough, then they sharpen the pistons on the valve side and install a crankshaft from the Niva, which also increases the working volume. Presumably after these operations you can get an engine with a displacement of 1.7 liters, sometimes 1.8 liters.

• Installing a new camshaft

This modification does not increase engine power, but changes the nature of its operation. In most cases, they try to install a camshaft that will transfer maximum torque to as low a speed as possible. This makes the engine more responsive at lower speeds, which has a very good effect when driving at low engine speeds. The best option for such a modification is a camshaft from Niva 21213.

• Installation of direct-flow exhaust and zero-resistance filter

The most popular modification. First of all, it's pretty cheap. Secondly, it allows the car owner to show off to neighbors in the garages. In fact, it does not have any practical benefit for the stock engine. Allows you to feel a slight increase in power only at high speeds.

It is quite effective when installing Turbo, since it does not put pressure on the engine, which is now capable of developing enormous power. Direct-flow exhaust is not convenient due to increased exhaust sound. It is dangerous to use the filter in wet weather, as it can let water into the engine, causing water hammer.

• Installation of turbocharging

The most expensive and effective way to increase engine power, while its resource sharply drops by 2-3, sometimes 4-5 times.

Requires deep exhaust tuning:

1. Installing T-Valves
2. Imported rings and forged pistons
3. Lightened crank feces
4. Intercooler and much more.

It is also necessary that your VAZ 2107 engine be fuel-injected. The carburetor can simply burst due to such high pressure. This article will not describe the procedure for installing Turbo on a VAZ 2107. There is enough such information on the World Wide Web. Here we will simply indicate a price of approximately 15% of the cost of the car. If you are ready to spend your money on this, go for it.

Useful information about the "seven"

ATTENTION! A completely simple way to reduce fuel consumption has been found! Don't believe me? An auto mechanic with 15 years of experience also didn’t believe it until he tried it. And now he saves 35,000 rubles a year on gasoline! Read more"

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.

Note. In addition, knowing these parameters of the car, you can easily restore the body after an accident. And one more thing: when buying a used “Seven”, it will be easy to find out whether the car has been in an accident by comparing the body dimensions of the VAZ 2107 with the standard ones.

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 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.

Continuer of traditions

The basis for the luxury rear-wheel drive “classic” of the Soviet automobile industry was the platform of the VAZ 2105. The car was produced in two versions:

1. With the VAZ 2107 index - for the domestic market;
2. With the index VAZ 21074 (outside the country - LADA-21074) - for export.

The price of the export version was slightly more expensive. However, a significant part of VAZ 21074 cars were sold in Russia. And most of them still serve their owners well to this day, who prefer to service the vehicle with their own hands.

However, in the process of repair and preventative maintenance of the car, the owner needs:

1. Instructions with wiring diagrams specific to this model;
2. Knowledge of the basics of working with electrical systems of VAZ family cars (see also the article Wiring - VAZ 2109: what is possible and what is not)

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.

Technical characteristics of VAZ 21074

The VAZ 21074 injector has its own technical characteristics that determine its operation. The car body type is a sedan with 4 doors and 5 seats. The vehicle's load capacity is 400 kg. The weight of luggage on the roof should not exceed 50 kg. The average ground clearance of a car is 16.4 cm. But its minimum value is 9 cm to the neutralizer, which must be taken into account when driving on poor-quality roads. The maximum speed of this car is up to 150 km/h. Acceleration to 100 km/h is carried out in 16-19 seconds.

The VAZ 21074 injector engine is an in-line four-cylinder with a cylinder diameter of 7.9 cm and a piston stroke of 8 cm. The power system is with distributed injection. Engine power 73.6 l. With. with a working volume of 1.6 liters and 5000 rpm. Regarding the VAZ 21074 injector transmission, the technical characteristics can be distinguished as follows. The car has a manual 5-speed gearbox. A car with rear wheel drive.

The chassis of the car is represented by two suspensions - an independent front suspension on two wishbones and a rear dependent suspension (with a rigid beam). The ground clearance of this car is at a high level, after all, it’s a Russian car. The braking system consists of a front disc brake mechanism and a rear drum mechanism.

In general, the characteristics of the VAZ 21074 injector indicate that the car is not bad and can serve its owner for a long time. It is reliable in operation, but it is impossible to talk about significant engine efficiency, since fuel consumption averages 6.8-9.6 liters per 100 km, depending on the type of driving.

Engines and transmission

“Sevens” are available with 1.3, 1.5 and 1.6 liter engines with power from 64 to 75 hp. With. These are models aimed at the domestic market. For export, the models were supplied with a 1.7-liter engine producing 80 horsepower. However, under the hood of a used VAZ-2107 you can find another unit. Amateur mechanics often test these machines and replace the original engine with one with different power characteristics. Such a replacement is popularly called “swap” (from the English swap - exchange).

The gearbox is a four- or five-speed manual, depending on the year of manufacture of the model, the drive is exclusively rear-wheel drive.

The model is economical in consumption and is not picky about fuel. In the combined cycle, the “Seven” consumes 7.5-8.5 liters per 100 km. You can fill the fuel tank not only with AI-92 and 95, but also with AI-80, if you can find it.

On-board computer for VAZ 2107 injector

The state, by the way, is not the only BC model that can be installed on a car with a 21074 engine, but we will still start with it, as with it officially developed under the wing of the automobile plant. Officially, the factory declares the device as intended for installation instead of a button plug. Well, it’s a good alternative, let’s see what it can do besides its main declared function.

Video tutorial on installing an on-board computer in a VAZ 2107

The device is fully compatible with January controllers versions from 5.1 to January 7.2, as well as Itelma, Avtelm 73 under Euro3, but is not intended to work with Bosch controllers, which are installed on nines. Therefore, the State 2107×1 works only with an injection seven engine. The device is quite easy to understand. It only has two buttons and three numbers. As a plug, you can't think of a better one. But besides this, the device has as many as 30 functions. It makes sense to dwell on some of the most useful ones in more detail.
