Car owners of the "classics" are often faced with the problems of dynamics and fuel consumption.Drivers call car engine heart, and the carburetor can be easily compared with the heart valve.It is up to the last detail depends on fuel consumption and dynamic performance depends on its correct adjustment.In this article, we learn about what's inside the carburetor (2107 DAAZ).We also look at how to regulate it properly.
fundamental unit DAAZ parts for classic models VAZ
operation of any automobile internal combustion engine depends on the quality and quantity of the mixture of fuel and air.This same mixture prepared immediately carburetor.Moreover, this device distributes the mixture over the combustion chamber.
Carburetor (2107 DAAZ) consists of several parts.This diffuser throttle, as well as jet and float chamber.
Device Types
If the car is an old motor, then these cars equipped with carburetors DAAZ 2107 - 1107010. With new motors and vacuum corrector applied a new model, or modification.This model DAAZ 2107 1107010-20.
These products are produced at the factory of automobile units Dmitrovgradskom.This company has a lot of years, it produces a variety of equipment for classic VAZ models.DAAZ 2107 (carburetor) among drivers has earned the special trust to be sufficiently reliable.
complex and precision instrument
The carburetor is a complicated device composed of many different components.But the complete unit must be only for those who are professionally engaged in setting and control of these devices.
However, despite all the difficulties and a large number of details, take a look at what's inside this machine specific.
So what is carb 1107010 DAAZ 2107 device?This device comprises a float chamber in which a limited number of supplied fuel.Access gasoline close the needle valve and the float, which in appearance resembles a barrel.Gasoline is mixed in a special mixing chamber.Also it consists of a carburetor throttle and the choke.In addition to them in the device and includes jets.Fuel is sprayed through the spray.One of the important components of the carburetor - diffuser.They work like a nozzle to create a configuration of air flow.
DAAZ 2107 carburetor: working principle
When the fuel gets into the float chamber, the volume of fuel is controlled by a float.If it emerges, it will block access to the needle mechanism of gasoline into the chamber.Thus, the camera in this case resembles a toilet tank.Here are all the same.But the fuel is supplied at once.First, it will pass through a special filter to clear.Further
device delivers the combustible liquid in the first and second fuel chamber.Carburetor DAAZ 2107 (device) provides for the main fuel jets, which runs out of fuel.Furthermore
gasoline through the air jet supplied with air in the chamber, which was previously cleaned in the air filter.The air then using special tubes and wells form a blend with gasoline.So, it turns out the so-called emulsion.
But that's not all.Before I get into the combustion chamber through the spray mixture passes through ekonostat.Here, the mixture passes further enrichment.
Next, using the spray mixture enters the diffusers.It produces the final preparation of the mixture.Carburetor vehicle 2107 (DAAZ 'ovskogo production) is designed so that fuel droplets in diffusers are involved in a high speed air flow.Thus, the air-fuel mixture into the center of the mixing chamber.
gas pedal on cars VAZ adjusts the position of the throttle valve, which is designed to feed the mixture directly into the engine cylinders.
What else is special carburetor DAAZ 2107?The device includes its jets for idling.In this mode, the mixture was taken only from the first fuel chamber.Principle and scheme of fuel cells involves the second chamber only when the output of the engine at operating temperature.II camera is also included if you need to quickly gain traction and speed.
differences in versions
As you know, in recent models of 2107 and other versions set a new carburetor DAAZ 2107 1107010 20. Let's see, what's the difference between this and the old carburetor modification 1107010.
According to information received from experts of AvtoVAZ,These two modifications are based on the same model.There is a fundamental difference between them - it economizer overrun.Model 1107010 has EPHH, and a new version is not equipped with this node.
Though DAAZ 2107 carburetor 20 and is not equipped with an economizer, it is equipped with a special jet fuel supply.The difference is that here the idling is adjusted by the electromagnetic valve.So, if the ignition is switched off, the fuel supply is cut off.

adjustment Before the adjustment it is necessary to find out which of the two versions installed in your car.So, if the car is equipped with a vacuum-proof-reader of ignition, whereas ICE machine - it's the latest model of Mercedes engines in 2103 or 2106 and the modification of the carburettor - new.If you do not find a vacuum-proof-reader, then you have the carburetor DAAZ 2107 1107010.
basic malfunctions
In order to allow for adjustment, it is necessary to know a few common problems.Since this node is responsible for the dynamic characteristics, the breakdowns can be attributed to:
- problems when you start the engine, the engine sneezing.
- jerks, twitching, frequent failures on the accelerator pedal.
- lack of overclocking options.
- increase in fuel consumption.
So, if the operation of your machine, you could fix one or more faults from the list, then the parts need repair.
should know that as much as possible to adjust the carburetor DAAZ 2107 1107010 can only be removed node.The process does not provide for the cleaning of this device or fleecy woolen cloth.Also, it does not need any wires to clean the jets.
beginning with the self-regulation is necessary first of all to remove the cover assembly.You can then proceed to adjust the float chamber.It's comfortable.
Adjustable float chamber
float has a free wheeling.Stroke size should be between 6.5 mm on one side and 14 mm on the other side.Adjust speed using the special template.
If your camera distance is less need to bend a little tongue of the needle valve.
Now you can adjust the operation of the needle valve.When the float rises, less fuel is supplied.When the throttle is opened, the fuel consumption is higher and the float descends.To adjust the float on the other side must take the maximum float back and using the same template to verify the setting.If the distance is 14 mm, while the emphasis should bend attachment.
Configure trigger
adjustment includes the process of adjustment of the starting device.Device for the old model is clocked at 1500 rpm.If you examine the DAAZ 2107 (carburetor for "Seven"), on the other hand, we can see a special channel.If you remove the assembly and inspect it back, you can see the channel for air supply.
To adjust, first you need to remove it.Then you must rotate the lever so that the air damper is completely closed.The following turn the unit, and then carry out measurements of the gaps between the flap and the wall.For our carburetor gap should reach 0.85 mm.To supply the necessary clearance for the size necessary to bend the rod drive.
Next you need to adjust the gap A. You can find it between the wall of the channel and the bottom edge of the flap.So, you need to close the valve and to drown the stem of the starting device.As a result it opens, and the gap should be from 5 to 5.4 mm.To adjust you need a screwdriver to rotate the adjusting screw.
Configuring idling
to get started is to ensure the correct adjustment of the ignition.The engine should be at operating temperatures.To adjust, rotate the adjusting screw as a fuel mixture until the engine speed will not be maximized.
Next you need to turn the screw counterclockwise the amount of fuel.It is to achieve even greater engine speed.
now worth more to twist the screw of quality to add some more turns.
meaning of these operations to the quality of the mixture was minimal, and the idling speed of 850 to 900. This is the most optimal values for gasoline engines of cars of family "Classics".More or less, this value should not make turnovers, as they will be considered unstable and will entail increased wear crank.
We have considered a number of possible adjustments that can be made with their own hands.But if you are not sure in their actions, it is better to entrust your DAAZ 2107 (carburetor from the "Group of Seven") professionals who are well versed.
