All serial cars are equipped with regular engines having average characteristics that correspond to the average consumer. In order to change the characteristics of your car, improve the dynamics and increase the power - without a solid tuning of the motor can not do.
And although the history of the VAZ 2112 brand is not so rich, like other models of VAZ, have already become a classic, this car became a favorite among folk craftsmen.
There are several methods for refining and improving the engine that can be held with their own hands:
1. Increased working volume.
This is a way, perhaps the most convenient and simple, therefore common. This will increase the torque of the motor without changing the driving style. This can be done in two ways: an increase in the stroke of the piston and boring cylinders.
- the increase in the stroke of the piston is achieved by installing a new crankshaft with a large eccentricity and selection of rods and pistons. Rolling rods are usually selected by weight and are installed mainly lightweight options. Because The piston is a key part in each engine, then the replacement of the piston group can be significantly increased efficiency and power. To top, a lightweight flywheel is installed. These operations will lead to a decrease in the load on the clutch and the crankshaft, which will accelerate overclocking and increase the dynamics of the machine.
- cylinder boring is a bit easier way. It is based on the fact that engines, as a rule, have a certain stock of the walls of the cylinders. From this we can conclude that the cylinders may be crowded, increasing the volume by increasing the heating of the walls. It's immediately because Built-in cylinders will begin to burn a more fuel per unit of time. The boring is carried out only on special equipment, as in the photo:
2. Increased compression ratio.
The essence of the concept of "compression ratio" lies in the ratio of cylinder volume to the total volume of the combustion chamber. By increasing the degree of compression, it is possible to significantly increase the power of the engine and its efficiency and at the same time slightly reduce
This is achieved by installing a new camshaft with other geometric indicators. The new camshaft will increase the volume of the combustion chamber without increasing the volume of the engine itself, which favorably affects its efficiency and power.
It is advisable to carry out this procedure in parallel with other modes of the engine, for example, with the installation of turbocharging. It should be remembered that the use of an engine with an independently elevated compression will require the use of high-quality fuel and engine oil from a motorist.
Otherwise, the engine can start tall, and the temperature may begin exceeding the permissible norm. You can increase compression ratio to 9.7 - 10.
3. Chip tuning
This is perhaps the most modern method. It is characterized by efficiency and relative simplicity. Its essence is to reconfigure the engine control unit, due to which some of its characteristics can be improved without risk to carry out its subsequent repair.
During the holding, standard software is replaced with sports, developed, for example, under the VAZ engine 2112 16 valves. At first, a controller program is read from the engine control unit by means of sensors. After this program varies taking into account the reserves and characteristics of the engine.
These works specialize special companies and car services that have the necessary software and personnel resources, because This requires experience and related engineering skills.
At the end, the reconfigured controller program is written to the car control unit. The advantages of this tuning is accessibility and relative simplicity. The situation is also eliminated when the VAZ 2112 engine is required, because It does not affect its mechanical part.
The only, perhaps, the disadvantage of this type of tuning is a slight decrease in exhaust ecology.
4. Installing turbocharging
This is the most common and effective type of tuning. The power characteristics of the car depends on the number of air and fuel, the mixture of which is flammable in the cylinder. In order to increase the power of the engine, you need to put in cylinders more volumetric.
But to increase the volume of fuel, it will be necessary to also need an increase in the amount of air, for which, actually, the turbine is intended. The exhaust gases pass through the impeller of the turbine, rotating it, and it also leads the compressor. Compressor and pumps air into cylinders.
The air is injected under pressure, therefore, comparing with undead engines, a larger amount of air is supplied. It is an increase in the volume of air injected into the cylinders, leads to an increase in the amount of fuel of the fuel, which significantly increases the engine power.
But it is worth remembering that the installation of the turbine is likely to demand the refinement of the cooling system. Video from the examples of the turbocharging to another car of the VAZ family - VAZ 1209:
5. Installation "Nulevik"
So in everyday life is called reduced resistance. It is intended to reduce resistance in the inlet system and thereby increase the bandwidth of the filter, due to which a small increase in power is achieved. These filters differ from the regular bandwidth.
In carrying out the engine tuning, VAZ 2112 needs a professional approach and attentiveness during all operations. Not every motorist understands the intricacies of the engine, so it is more expedient to trust your car with experienced professionals. It will save you from inevitable mistakes during tuning and save a lot of time.
