• Oka 0.7 Fuel consumption rate Oka 0.7 l per 100 km

The small car "Oka", developed in 1988 at VAZ, was supposed to become one of the most popular cars before the collapse of the USSR, but until 1994 it was produced in small batches, and since 1995, production was completely transferred to KamAZ and SeAZ. The peak of production began in 1998, when Oka began not only to be sold domestically, but also actively exported - due to the fall in the ruble exchange rate, its price in foreign currency turned out to be ridiculous. But the outdated design of the body and power unit did not allow the car to successfully compete with higher quality and reliable foreign analogues in the early 2000s, so its production was discontinued in 2008.

Oka 0.7

From the very beginning, a VAZ-1111 micro-displacement carburetor engine with a volume of 649 cm3 was developed for the Oka. This two-cylinder engine was capable of developing a power of 30 hp. and reach a torque of 45 Nm. The engine was paired with a 4-speed manual transmission.

Oka fuel consumption rate is 0.7 l per 100 km

• Maxim, Ufa. I have an Oka VAZ-1111, manufactured in 1994. Despite its unpresentable appearance, the car is not bad and suits me 100%. For its weight, the engine power is quite enough. By the way, consumption in the city is quite normal - 5-7 liters, but on the highway, if you drive too hard, sometimes it can reach 10 liters.
• Timur, Ryazan. I took it literally for a couple of years - it was stupid to learn how to drive. Even if I knock or break it, I don’t mind at all. However, everything turned out to be not as sad as I thought. It drives and that’s the main thing, although it doesn’t even smell like comfort. The average consumption is 6 liters – which is a lot for the tiny volume under the hood.
• Georgy, Tambov. Oka is my first car. I got it from my dad, and before that it had been sitting in the garage for five years and was rusting. Of the advantages, I will only note its unpretentiousness and the fact that it is the same Lada, only neutered and trimmed down. Gasoline consumption with a normally adjusted carburetor is 6 liters in the city, more on the highway, because the gearbox is 4-speed and at more than 90 km/h it eats gasoline like a cow.
• Irina, Rostov. When I decided to learn to drive a car, I went to a driving school, after which my father finally entrusted me with his car - a 1992 Oka. At that time, for me it was just something - but now I understand that the car was an outright log and not worth a good word. It broke down constantly, the consumption in the city was no less than 6 liters, I now have this consumption on my Hyundai with an engine 2.5 times more and 3 times more powerful.
• Sergey, Moscow. At one time, I rode a 1993 Oka for about a year and a half. This was in 2008 - I needed wheels, but there was no money, so I took an Oka, which at that time cost me about $300 - just ridiculous money. I’ll tell you that in fact everything is not as bad as it seems - if we put aside emotions, demands for comfort and all that, then this car fulfills its main purpose of transporting you from point A to point B 100%, and nothing more. need to. Consumption in the city is on average 6.5 liters, and it is generally undemanding when it comes to the quality of gasoline.

Among the main disadvantages, according to users, is the error of the speedometer and odometer. The readings from the device are greatly underestimated, as a result of which it is practically impossible to find out the real consumption of the Oka. This has been verified by more than one owner with the help of other cars when driving in pairs. The magnitude of the error is truly amazing. On average, instead of the 300 km traveled, the VAZ-1111 odometer showed a result of 100 km less.

Today, the owners agree that, given the age of the car, the Oka, whose fuel consumption is less than 10 l/100 km, is a good car. Anything more is no longer the norm. This is such a “psychological” mark.

Oka 0.8

In 1995, on the basis of the fairly successful VAZ-21083 engine, a stripped-down two-cylinder version of the VAZ-1113 was developed, which was equipped with the Oka car. This 750 cm3 carburetor engine developed a power of 35 hp, and the engine torque was 52 Nm. The engine was paired with a 4-speed manual transmission.

Real reviews about Oka fuel consumption 0.8 l per 100 km

• Andrey, Vladimir. I have a 2002 Oka with a 0.75 liter engine. For the money, the car is not bad, but when compared with others, it loses to everyone. There are simply zero amenities in the cabin, it constantly breaks down, although spare parts are very cheap and cost pennies. Over the course of a couple of years, I replaced four bumpers – repairing them is not an option at all, only replacing them. Consumption in the city is 7.5 liters - I’m surprised, I thought it would be much less.
• Evgeniy, Kursk. The car was made in 1997, naturally I took it second-hand, with a mileage of more than 60 thousand km. At the same time, the car stood in the garage for almost 6 years - naturally, I had to change all the gaskets, rubber bands, etc., and fill in technical fluids. The problem was with the wiring - it kept melting. Nevertheless, it is quite unpretentious and easy to maintain, but the consumption is high, as for a 0.75 liter engine - approximately 7-7.5 liters in the city, 6.5 liters on the highway.
• Kirill, Ufa. Considering that the engine in my Oka is half of the figure-eight engine that is installed on the VAZ-21083, I can’t understand why it consumes so much gasoline. The actual consumption is within 7 liters, my friend has a VAZ-21083, so that one consumes 8-9 maximum.
• Dmitry, St. Petersburg. The main advantage of Oka is its compact dimensions. It looks like there's no room, but there's actually plenty of space, especially for the driver and front passenger. Of course not at the back, but that's not a problem. Plus you can park wherever you want - for St. Petersburg this issue is acute. Consumption in the city is about 7-8 liters, but it pulls surprisingly well, you can even overtake.
• Vladimir, Orel. I owned the VAZ-1113 Oka for almost 4 years. At the time of purchase, the mileage was 45,000 km, the car was owned by a retired grandfather, who drove it once every five years. The advantage of the car is its size and the 0.75 liter engine, which is high-torque for its volume. Everything else needs to be improved - the steering, suspension and so on have been redone. Well, the weak metal of the body began to rot very quickly, even though I cooked it.

Modifications

Real gasoline consumption of VAZ 21099
Over the years of production of the Oka model, many modifications have been produced. The car was produced with two main types of engines - 0.65 and 0.75 l, and depending on the installed power unit, it could have an index of 1111 (0.65 l) or 11113 (0.75 l). The factory designation of the model indicated the Volzhsky or Serpukhov Automobile Plant - VAZ or SeAZ, the cars were produced in various versions:

• for disabled people – SeAZ-1111-01/ SeAZ-1111-02/ SeAZ-1111-03 with a 0.65 l engine and SeAZ-11113-01/ SeAZ-11113-02/ SeAZ-11113-03 with a 0.75 l engine ;
• basic models - VAZ-1111 and VAZ-11113;
• a car with a 4-cylinder engine from Tavria - Astro-11301;
• model with a 1.0 liter engine in various modifications of SeAZ-11116, including pickups and vans.

Oka 1.0

The latest versions of the Oka, produced at SeAZ since 2006, received a Chinese three-cylinder small engine with a volume of 1000 cm3, which was also installed on the Daihatsu Charade G10. This engine was significantly superior in its characteristics to VAZ units - its power reached 53 hp and torque - 77 Nm. In addition, a more modern 5-speed manual transmission was offered for this engine.

Real fuel consumption Oka 1.0 l

• Yuri, Kaluga. I bought Oka for one simple reason - money, or rather, the lack of it. Actually, I have a GAZ-3110, but this car is too power hungry and not suitable for every day. But the Oka, especially with an imported engine, has low consumption, about 6.5 liters in the city and 5 liters on the highway - the Volga has two to two and a half times more. That’s why I ride the Oka all over the city, and if I go somewhere with my family, it’s on the Volga.
• Alexander, Kirov. I've had Oka for over 10 years. I have driven more than 200 thousand km. During this time, I made a capital overhaul of the engine - at 150 thousand km it stupidly caught a wedge, I had to completely overhaul it. By the way, after the capitalization the engine began to work perfectly simply - consumption dropped to 6 liters on average, sometimes even less, it pulls amazingly with such a volume. Plus I did the steering properly and slightly modified the suspension.
• Vasily, Samara. My Oka is a car for every day. I don’t care that the car is not prestigious - the main thing is that it drives and at the same time consumes a minimum of gasoline. I pump out 20-30 liters per day, covering 350-400 km. And it’s very cheap and easy to repair; it can be done by any auto mechanic whose hands grow where they need to.
• Dmitry, Simferopol. Through a friend, purely by chance, I became the owner of an Oka with a Chinese 1.0 liter engine. I bought it solely because of the price - they offered it to me for 400 bucks, a “penny” costs an order of magnitude more. The car is nothing at all - the interior completely sucks, there is no space at all, the engine has a thousand cubic meters, but in the city it consumes at least 7 liters of gasoline.
• Alexey, Moscow. My father-in-law gave me the car so I could learn to drive. He bought himself a Priora, and I didn’t have much money, so for me any option was normal. Over the course of 2 years, I certainly killed her in the trash, but I didn’t feel sorry for her. What was pleasing was the consumption of 6 liters, and sometimes even less.

14.8.3 “Eats a lot”, but rides quietly

14.8.3. “Eats” a lot, but rides quietly

If the engine starts poorly, pulls poorly and consumes a lot of fuel, the problem may not be what you first think about. A seemingly simple situation from the point of view of determining the root cause is the most insidious. Many bravely begin an independent search, not realizing that these manifestations can be the result of a number of reasons - from elementary to quite serious. It’s good if you have a car that uses simple and outdated technical solutions - the classic Zhiguli, Moskvich and Volga - you can safely contact auto mechanics who have experience in repairing such cars. But after changing their car to a more modern one, many car enthusiasts continue to turn to the same specialists. And they don’t have the courage to admit that they don’t understand the complex processes in fuel systems and electronic ignition circuits. They look for a spark to break down, breaking through transistors, the insulation of bobbin windings, high-voltage wires, and “making” conductive paths on the covers and runners of the distributor. Without solving the problem, such mechanics drive the “disease” inside. And in the end, the owner still goes to professionally trained engineers. But “treating” the machine is already significantly more difficult. Experts often find themselves in a situation where, after a long period of work, even with the help of instruments they cannot understand anything. And only after a while it turns out that the previous “clever guy” tightened the jets in the carburetor or twisted everything in the injector, and in the end broke its tightness or burned the pressure sensor.

The list of possible reasons leading to increased fuel consumption and reduced power is very rich. And besides them, there are a number of uncharacteristic, but often encountered problems, such as piston burnout, fuel getting into the oil, failure of one of the injection system temperature sensors, failure of the thermostat, confusion of vacuum tubes, destruction of one of the carburetor gaskets, piston rings or piston baffles.

Diagnostics must be carried out without disassembly, since otherwise there is a high chance of only temporarily eliminating the investigation or even adding new, sometimes more complex, problems to the existing problem.

For example, there are many reasons leading to a decrease in spark power. If diagnostics are carried out using a multifunctional motor tester, on its screen you can immediately determine what the defect is. In any other way, it is impossible to assess the correspondence of the form of the spark-forming process to the one in which complete combustion of the fuel occurs in various operating modes.

A common situation is when, having discovered signs of abnormal operation in the engine, a car owner goes to a mechanic. He, having measured the engine compression and found compliance with the norm, begins to adjust both the carburetor and the ignition system, achieving stable operation. Sometimes it works. The engine starts up regularly and stops stalling, but the thrust and fuel consumption leave much to be desired. Where is the mistake?

In a worn-out engine, valve seals often leak. Oil leaking onto the pistons leads to artificial compensation of gaps that have arisen due to wear of the pistons, rings and cylinders. And when measuring compression, false readings are obtained. Fixing this problem after a “repair” made by a mechanic is significantly more difficult due to the need to restore the original adjustments.

The opposite situation is also very common, when the owner is unjustifiably “thrown” into major repairs, although it would be enough to replace the same oil seals, which is more than 10 times cheaper.

Unfortunately, the car maintenance market still remains approximately equally divided into stations that meet modern requirements for qualifications, technical and cultural maintenance, and into fragments of the sadly memorable Soviet car service center. Therefore, car owners should carefully familiarize themselves with the technical center where they park their car. And not so much with the cost of services, but with how, with what and under what conditions the car will be diagnosed and repaired.

Adjusting the power system

If your car has a Solex carburetor, how to reduce fuel consumption is not an idle question.

One of the main reasons for increased gasoline costs in carburetor engines is an unregulated power system. You can check this yourself by removing the air filter cover and taking a closer look at the position of the air damper.

If the damper is opened even just a little, then it already creates a kind of screen above the diffuser. This increases the flow of the mixture due to increased vacuum. Many cars equipped with Solex have problems with overspending precisely for this reason (VAZ - 2108, VAZ - 2109, VAZ - 21213).

Also, when carrying out this procedure, you should pay attention to the condition of the air filter itself. A clogged, dirty filter leads to over-enrichment of the mixture with gasoline

It is advisable to replace such a filter.

Often, carburetor masters, in pursuit of improving dynamics, bend the nozzle tube of the accelerator pump of the secondary chamber so that gasoline flows from both tubes only into the first chamber. This leads to large excess consumption of fuel and “nervous” behavior of the car.

Official consumption data

The first Oka to roll off the Oka assembly
line was offered in a hatchback body with three doors, with a detachable subframe attached to the body through rubber cushions. Interestingly, the safety indicators with this arrangement are higher than with classic models. Several engines were installed on the car during its production; they were distinguished by their reliability and maintainability, sufficient engine life, and good traction. The fuel consumption of Oka engines, paired with a four-speed manual transmission, is characterized by increased efficiency.

The first models were equipped with two-cylinder petrol carburetor engines with a volume of 0.65 liters and 29 horsepower. With this unit, the car accelerated to 120 km/h, although the dynamics were modest - the car accelerated to the first hundred in 24 seconds. The fuel consumption of this engine was:

• in the city 6.5 liters;
• on average 6.1 liters;
• on the highway 5.5 liters.

To improve dynamics, in 1995 they began installing a 0.75 two-cylinder engine on the car, which developed 33 horsepower, which increased the maximum speed to 130 km/h. This is how the VAZ 11113 Oka appeared with more balanced characteristics. Oka was refueled with AI 92 gasoline, its consumption was:

• in city mode 7.4 l;
• mixed cycle 6.8 l;
• on the highway 5 l.

In 2006, it was decided to modernize the car and abandon domestic engines; Chinese three-cylinder engines with 1.0 engines and a power of 53 horsepower, equipped with a direct fuel injection system and five-speed manual transmission, began to be installed on the Oka. The maximum speed has increased to 150 km/h, traction has improved and vibration has decreased. Gasoline consumption was:

• in traffic 8.5 l;
• average 7.7 l;
• on a free road 6.1 liters.

Basic faults

Kia Rio fuel consumption

In the early days of the 1111/11113's existence, Oka owners often complained about increased annoying vibration and noise from the engine compartment. The noise was especially loud when the engine was warming up; the balancer shafts mentioned above were to blame for it. This phenomenon worries car owners, but is not considered a malfunction. The engine may also be noisy due to too large valve clearances. The problem is eliminated by adjusting them. Vibration is a design feature, since the engine only has two pistons. A fairly common problem with engines is burnout of the cylinder head gasket. Its main reasons:

• factory production flaws, when the gasket was manufactured with inaccuracies;
• Incorrect tightening of the cylinder head, in which the gasket is not fully compressed.

If the motor is repaired, the seal is replaced and cannot be reused.

The Oka 11113 engine may have difficulty starting “hot” after a short stop. The reason for this is the layout of the engine compartment and problems with the fuel pump diaphragm. In a hot VAZ 11113 engine, fuel vapors are formed, including in the cavities of the fuel pump, and this unit is not intended for pumping gases and can “fail” when starting the engine before it cools down. The aperture can be changed.

General description of the carburetor, design features

What kind of carburetor is on OKE? This device is produced at the Dimitrovgrad Automotive Unit Plant, it is called the DAAZ 1111 1107010 carburetor.

The OKI carburetor, after modification, has some features that distinguish it from analogues installed on other cars, for example, the float chamber is located across the carburetor body. This approach allows you to obtain an enriched fuel mixture during acceleration or braking.

In addition, carburetors in this series have a simplified design due to the fact that there are practically no electronic components.

The design of this unit includes the following assembly units and components:

• valve mechanism;
• engine starting device;
• fittings;
• adjustment lever;
• throttle valves;
• chamber with a float mechanism.

All of the listed components are assembled in one housing. To protect them from street dirt and atmospheric influences, a protective cover is installed.

In an OKA car, the carburetor can be divided into three parts - upper, middle and lower.

Carburetor DAAZ 1111 1107010 top view of the carburetor: 1 - accelerator pump cover, 2 - solenoid valve on the fuel jet of the idle system, 3 - air damper of the starting device, 4 - cover of the diaphragm mechanism of the starting device, 5 - lever of the starting device, 6 - holder sheath of the air damper control cable, 7 - crankcase gas supply fitting. 8 — fuel supply fitting.

The first includes the cover, air filter mounting studs and fuel supply fittings. The second part includes the carburetor itself, complete with diffusers and a float chamber, in which the proper fuel level must be maintained. The third is equipped with throttle valves and drive rods.

The carburetor that is installed on an OKA car is designed to solve the same problems as similar devices that are used on other models of passenger cars. And the operating scheme of such devices is approximately the same, that is, liquid fuel enters the float chamber and is supplied to the chamber where it is saturated with air.

Fuel droplets are crushed using atomizers installed there and this allows air to easily penetrate into the fuel. After enrichment, the mixture, passing through diffusers, rushes into the combustion chamber.

Setting the ignition timing

When the ignition timing is correctly set, all indicators of engine performance (reactivity, power, idling, energy consumption) are within normal limits. To carry out the work, you must have a strobe and a tachometer, an open-end or socket wrench of 10. In general terms, the setup is done as follows:

• The engine warms up to operating temperature. Low idle speeds are set by ear or on the tachometer (less than 800 rpm), after which the engine is turned off.
• On the gearbox housing, look for a hatch with a visible part of the flywheel and a scale. Most often it is closed with a rubber stopper that needs to be removed.

By turning the flywheel with a screwdriver, the long alignment mark is located. The lead angle is 0 degrees if the mark is opposite the triangular notch on the scale. In this case, the pistons of cylinders 1 and 4 are at top dead center.

The strobe light is connected and the engine is turned on to idle. A flashing strobe beam is directed into a hatch with a scale. In the beam, the highlighted mark should be opposite the desired scale division, where each division corresponds to one degree of ignition timing.

The advance angle is adjusted by rotating the distributor (ignition distributor housing). Clockwise - the advance angle increases (early ignition), counterclockwise - decreases (late ignition). When the desired angle is set, the engine is turned off, the strobe light is turned off, and the distributor is secured.
