The fate of "Oka". Other names

VAZ introduced a new competitor to the Mercedes ml. It is not clear why the news about the appearance of a new AvtoVAZ model drew attention only in the first quarter of 2022, the Lada Vesta Cross car model was presented for the first time at Moskovskaya. I always liked the dynamic window sill line, which goes without breaking into the hood connector on the first Oka; this primarily distinguished it from the prototype of the Daihatsu Cuore.

Modifications and updates Edit

Over the many years of production, the Oka was regularly modernized: the instrument panel, the heating and ventilation system of the body, as well as some body parts, primarily the plastic body kit, including the radiator grille and bumpers, were repeatedly changed. Larger wheels began to be used (R13 instead of R12).

In 2006, production of Oka at ZMA was discontinued due to the purchase of this enterprise (now Sollers).

SeAZ-11116 - one of several modifications of the Oka

At the only remaining SeAZ in 2006, production of its modification SeAZ-11116 with a Chinese 3-cylinder 1.0-liter injection engine (Oka-2) was launched. In addition to the new liter three-cylinder engine (instead of the previous 0.8 liter two-cylinder), the car received a new five-speed manual transmission, the maximum speed increased (from 123 to 150 km/h), and the acceleration time to 100 km. per hour (from 27.5 to 18 sec). The new engine made it possible to ensure compliance with Euro-2 environmental standards, and since January 2008 - Euro-3.

In 2007, a pilot production batch of pickups and vans of the SeAZ-11116-50 subfamily was produced, and a reinforced version of the SeAZ-11116-60 pickup, semi-frame design, with a load capacity of 400 kg, was developed. Despite the fact that these were the most affordable commercial vehicles, they did not go into production.

In January 2009, SeAZ stopped production of Oka due to its unprofitability.

Cylinder block

The power plant crankcase is made of cast iron. As on all VAZ models, the cylinders are not inserted, but bored into the block. The cooling system channels (the so-called “jacket”) run throughout the block.

Since the power unit is a two-cylinder, in-line, there are only three supports for the crankshaft main journals at the bottom of the block. During the production process, high-precision machining of the working surfaces of these supports is carried out simultaneously with the covers.

As a result, each support has its own cover and they cannot be swapped, otherwise the crankshaft may rupture during operation of the car. To eliminate the possibility of installing the cover in the wrong place when repairing the power unit, they are marked.

The cylinder head is solid cast aluminum. Since the engine has a timing belt with an overhead camshaft, the cylinder head is equipped with beds for the shaft. To install the camshaft, three beds with covers were made. There are no shaft bearings; their role is played by the working surfaces of the bed and cover (therefore, if the bearings are heavily worn, the entire head must be replaced).

The cylinder head also houses timing valves (2 for each cylinder). As usual, the intake valve, to ensure better filling of the cylinder with the combustible mixture, has a larger diameter than the exhaust valve.

The cylinder head is fixed to the block with 6 bolts. When tightening fasteners, a certain pattern is used, which eliminates the possibility of the head being “skewed.”

Bolts require gradual tightening with increasing tightening torque. The force on the cylinder head mounting bolts has strictly defined values, so tightening must be done with a torque wrench.

The camshaft is made of cast iron, has a high degree of processing of the working surfaces - bearing journals and cams. In addition to acting on the valves, the camshaft also drives the vacuum fuel pump, for which there is an eccentric on the rear of it.

Thermal clearances on Oka engines are adjusted using special washers installed between the camshaft cams and valves.

The crankshaft is a magnesium cast iron casting with subsequent high-precision machining of the working surfaces. It has 3 main journals and 2 connecting rods. 4 shaft cheeks, located between the journals, act as counterweights that reduce motor vibration during operation. The working surfaces of the crankshaft are lubricated through oil channels made inside the shaft.

History of VAZ 1111/11113 engines

The engineers who developed the Oka car faced a rather difficult task - to make a compact and affordable vehicle, made from common components and with good maintainability. Similar requirements were put forward for the engine - it had to be simple, reliable and easy to repair in the event of a breakdown outside specialized service stations with qualified personnel.

Description

The presented model is a type of four-stroke carburetor-based engine.

Its distinctive feature is that the camshaft is located at the top of the Oka engine. Not all modern and old power units are equipped with such a feature.

It is worth noting that all cylinders are in-line, which allows for very good technical potential. The designers of the Oka car took one half of the well-known VAZ 21083 and made it the basis. It follows from this that some parts and mechanisms are no different from their older brother.

As for the cooling system, there is a closed-type liquid circulation. Therefore, the Oka engine will be able to operate in any weather conditions, which is very good. He is not afraid of severe frosts and heat. Thanks to the combined lubrication system, all parts and mechanisms will work virtually without failure.

Performance characteristics of the VAZ 1111 Oka © Engine characteristics

Vibration has a constructive reason and is caused by the operation of only 2 pistons, which have a working stroke of only 2 rotations of the CV, that is, during operation, 1 piston rotates the CV 360°. Strict price restrictions implied constant control of the cost of the product at all stages of its development; the 3500 bar itself was at the level of the then prices for classics.

Design

In fact, this is a standard engine from the VAZ 21083, which is very popular. The Oka engine is slightly modified and weighs half as much. Due to this, it was possible to obtain low fuel consumption and high efficiency.

It is based on a simple four-stroke power unit running on gasoline fuel. The main features include the overhead camshaft and in-line arrangement of the cylinders. Thanks to this, it was possible to obtain high power.

"Oka" VAZ (SeAZ, KamAZ)-1111

- Soviet and Russian minicar passenger car of the first group of the especially small class (segment A - minicars). The car was developed at the Volzhsky Automobile Plant and produced at VAZ, KAMAZ and SeAZ in 1988-2008.

Motor VAZ 11113

Since 1995, a new 0.75 liter engine has been installed on the Oka.
It is believed that this modification is highly economical. Thanks to the low operating speed, the minicar engine “eats” only 6 liters of gasoline when driving 100 km in the city. The maximum speed of the VAZ-11113 Oka is 130 km/h. The power unit is a two-cylinder engine. Many parts are interchangeable with the VAZ 2108 engine, but this does not mean that the power units are identical. To remove the strong vibration inherent in a two-cylinder engine, there is a special balancing shaft on which counterweights are installed to dampen vibrations. The shaft has a rigid drive in the form of gears. This is the cause of the rumbling noise of an engine that is not warmed up to operating temperature.

As it warms up, the noise disappears, but not completely. This is a serious irritant for drivers who have just started operating an Oka car. The technical characteristics of this mechanism play an important role in the operation of the entire unit. And after a short period of time, addiction develops, and other advantages of a small machine begin to dominate this disadvantage.

The car's ignition system is one of the most reliable in the world. The weak point in a contactless electronic system can only be the ignition coil. Otherwise, the system is very reliable; it is enough to monitor the condition of the high-voltage wires and promptly replace the spark plugs.

Another feature of the engine: for reliable and long engine service, it is necessary to maintain a strictly average oil level. Overfilling or lack of lubricant will very quickly lead you to a repair shop. And the cost of repair work will be the same, regardless of the model, be it a Lada Kalina or a VAZ 1111 Oka.

Vehicle identification

Like all cars, the Oka had identification numbers applied to the body and engine. The body number was additionally an identification designation of the car itself.

The identification number was applied to the car body in three places, which eliminated the possibility of counterfeiting. The first number was applied to a special plate attached to the front of the body, in the engine compartment. This plate also carried information in the form of a code about the manufacturer; the model index and model year of manufacture were applied to it.

The identification number was additionally applied to the body under the air intake grille located near the windshield.

The third number was applied inside the cabin, on the cross member of the trunk floor.

The engine had an identification number in only one place - on the front cylinder block, next to the second cylinder.

The VAZ car surprises with its technical characteristics despite its more than modest size. The Oka accelerates quite quickly, has excellent cross-country ability, and at the same time is very economical in fuel consumption. But the new product did not go into wide production due to many problems and the need for improvements, although today you can still buy a kit to convert the engine into an injection one.

Tuning

Many drivers want to make a real monster out of their iron horse. This also applies to the small car Oka.

If you want to increase power, you can tune the Oka engine.

This requires a special tool, workshop and experience:

1. The first step is to replace the cylinder head, air filter, buy a new camshaft and carburetor. In fact, this is the bare minimum that can be done at the first stage.
2. You know that Oka's car does not have a very large engine capacity, and there is no way to fix this. Of course, you can try to install a different engine, but this is very difficult and time-consuming. Less expensive is chip tuning, which allows you to slightly increase torque and compression. In addition, fuel consumption is reduced, which is very good.
3. Many experts recommend grinding the manifold, lifter and camshaft. These actions relate to the main tuning of the Oka engine. With this you can not only increase power, but also make the engine run smoothly.
4. Many drivers ask the question: what engines can be installed on an Oka car? And the answer is very simple. Only standard or slightly modified from VAZ 21083.

At one time, the Serpukhov Automobile Plant produced the S-3D motorized wheelchair, which was mainly intended for people with disabilities, and was popularly called a wheelchair. Similar requirements were put forward for the engine: it had to be simple, reliable and easy to repair in the event of a breakdown outside specialized service stations with qualified personnel.

general description

The VAZ-1111 engine is an in-line, two-cylinder, transversely mounted. Thanks to this arrangement, the engine compartment turned out to be compact, which made it possible to reduce the overall dimensions of the car. The engine received a liquid cooling system with forced circulation, a carburetor power supply system and an electronic ignition system.

Model 11113 has the same design of the power unit. The difference between the engines of these modifications is the basis. Version 1111 is, in fact, “half” of the 1.3-liter VAZ-2108 unit, and 11113 is a 1.5-liter engine of the same G8. Because of this, the engines have different engine displacement and power.

The power plant is fixed in the engine compartment on a special subframe. The manufacturer did not provide protection for the Oka engine.

Despite the fact that the installation was based on a 4-cylinder engine, the Oka unit has one very interesting feature - synchronous stroke of the pistons. If you look at the Oka engine in cross-section, the pistons are located at the same level and “walk” together, but the cylinders function separately.

The operating principle of an engine with this design feature is quite simple - the strokes in the cylinders are offset. That is, if the compression stroke occurs in the 1st cylinder, then the exhaust stroke occurs in the 2nd cylinder. And so on for all strokes, so the cylinders in this engine work alternately.
