VAZ-2101, the engine: the characteristic, repair, assembly

The car VAZ 2101 engine has a working volume of 1.2 liters. This is the minimum volume of the engine, it was installed on virtually all VAZ cars. Some argue that the penny was put on motors from Fiat. But do not forget that the engine of the 2101 was made really based on the motor of an Italian car. But the distance between the centers of the cylinders is much larger than that of Fiat. Due to this, VAZ engineers could on one basis make an engine with a different volume. Actually, motors with a working volume of 1.5, 1.6, 1.3, as well as for Niva cars, came from it.

Positive engine performance

On the "penny" is a 4-cylinder in-line engine, the camshaft is located at the top. The drive of the gas-distributing mechanism on the "penny" is carried out by means of a chain. If you do not sever the engine severely, then its resource is about 200 thousand km. It is worth noting that several decades ago, tests were carried out on engines that were installed on cars that traveled throughout the Soviet Union. The tests involved cars that traveled through deserts, steppes, in permafrost conditions. And the motors have passed more than 200 thousand kilometers. And they never undergone major repairs. As shown by the tests carried out, they could still serve for a long time without repair. Their resource was quite high. At the same time, only the one recommended by the manufacturer was poured into the VAZ 2101 engine.

Motor maintenance

True, the engine needs to conduct timely maintenance. In particular, it is demanding on the size of the valve clearance. Approximately once for ten thousand kilometers of run it is necessary to carry out adjustment. If this is not done, then there will be a knock, and after warming up the engine may simply decay. As for the system of injection of a penny engine, it also needs adjustments and repairs. It is worth noting that the motor has a lot of disadvantages, if you look at it from the point of view of modern technologies. About 700 grams of oil is consumed per thousand kilometers. This is very much. Also, the engine overheats quite often. And the reason for this can be covered both in the thermostat and in the liquid pump. It is much less frequent in the failure of the fan. Some still have a cooling system that uses an impeller with a mechanical drive. Sometimes the high temperature in the engine is manifested after refueling with gasoline with a very high octane number. By car VAZ 2101 engine power can be increased, if you perform some modernization. About it will be told below.

The smoke from the exhaust

If the engine started to smoke, then, most likely, there was a destruction of the oil seals on the valves. Or the guiding bushings were completely worn out. Among the minor faults can be identified, for example, improperly tuning the carburetor, it creates a too rich mixture. And the most sad breakdown is the destruction of the rings on the pistons. The VAZ 2101 engine was initially equipped with a classic ignition system. It is very fastidious, requires constant care, cleaning of contacts, adjustment of gaps. Therefore, many motorists prefer to install a non-contact ignition system. But what kind of engine can I put on the VAZ 2101? The answer to this is one - any! Everything depends only on how "golden" your hands are.

Piston group

Fortunately, it is possible to improve the motor if it is modernized. Of course, you have to get rid of all the shortcomings that are described above. It will also be necessary to acquire the necessary tools and materials, which entails certain financial waste. It would be much easier to install the engine from the nine or twelve, they are more high-speed and powerful. And most importantly - ideally suited for fasteners. Of course, you can make a boring of cylinders to a diameter of 82 millimeters, to subsequently install the pistons from the car "Niva". But pay attention to the fact that the bottom of the pistons was flat. It is best to take these elements from the car VAZ 2112. Provided that the total stroke is 66 millimeters, the engine volume will increase to 1.4 liters. Therefore, the power characteristic of the VAZ 2101 engine will improve much.

Nuances of tuning

But pay attention to what year of release of the engine of your "penny". If earlier 74 years, this option with pistons "Niva" can ride. If later, you can install pistons with a maximum diameter of 79 millimeters. It is desirable to install the crankshaft from the newer model 2103, it is advisable to take the connecting rods from it. But keep in mind that you should not install short connecting rods. They increase the force with which the pistons are pressed against the cylinder. Consequently, the reliability of the motor, as well as its resource, is deteriorating many times. And when repairing the VAZ 2101 engine with your own hands, consider all the nuances, try to comply with the requirements.
