The work of each automotive engine depends on the amount and quality of the air - fuel mixture prepared by a special device called a carburetor. All carburetor systems create a mixture and help evenly distribute it along the cylinders. Mix fuel with air flow in different ways. For example, there are carburetors membrane - needle, and there are float. It is to this type that the carburetors of the VAZ family include the production of Dimitrovograd Auto Agricultural Plant (DAAZ).
Adjusting the carburetor VAZ 2107 is an important tool to save the engine in working condition.
Before adjusting the carburetor, you need to know which type it is installed on the car. To do this, you need to remember that:
The main knots of the carburetor subject to adjustment:
In order to adjust the carburetor, you need to know the main signs of its malfunction. Since the carburetor is responsible for the accelerated dynamics of the car, these include the following:
- difficulty when starting the engine, long "sneezing";
- all sorts of "jerks", "jerking", "dips" when you click on the "Gas Pedal";
- the sluggish ability of the car to overclocking;
- inexplicable increase in gasoline consumption.
So, if your car has the corresponding "complaints", proceed to its adjustment.
Attention! Most correctly can be adjusted on the removed carburetor. The carburetor adjustment of the VAZ 2107 does not imply the use of porous and woolen fabric, as well as various wires for cleaning the jets.
How to adjust the carburetor on your own on the VAZ 2107? When removing the cover of the carburetor, the float system is adjustable, so convenient.
Adjusting the float system
The free course of the float ranges between the following values: 6.5 mm on the one hand and 14 on the other. This can be adjusted using an inspection template, putting a vertically chamber. In this case, the float is slightly concerned, but does not prescribe a valve ball.
In the event that a distance is less than 6.5 mm, then you need to slightly bend the valve tongue (needle), which in the figure is depicted by the letter "A".
After that, regulate the degree of opening of the needle valve, which passes gasoline into the float chamber. When approaching the float, the flow of fuel is reduced, with a sharp press on the gas pedal and the opening of the throttle, fuel consumption increases, and the float is lowered.
Now regulate the deviation of the float to the other side. To do this, maximize it from the lid and check the template, the thickness of which is 14 mm with a certain admission.
If the distance does not match, you need to adjust the fastening bracket of the float and make it no more than 14 mm.
Now, after adjustment, the free flow of the float is about 8 mm. The VAZ 2107 carburetor adjustment also provides for checking incoming grids and fuel filters to maintain a full fuel flux.
Start adjusting the starting device
Setting up the VAZ 2107 carburetor with its own hands, includes adjusting the starting device. Recall that it serves to confidently run the cold engine. To do this, the mixture is twice, three times more saturated with fuel than with the usual nutrition of the hot engine.
The 1007010 carburetors starter triggered at a frequency of 1500 revolutions, that is, when the manufacturer recommended by the manufacturer of the cold engine start.
If you look at the carburetor on the side, then the channel is clearly visible, through which the vacuum is supplied from the smoke of the throttle on the diaphragm of the flap:
If you remove the carburetor and look at it on the reverse side, then the airproof channel is visible:
If you disassemble the carburetor, you can see the details of this diaphragm starter:
Below is a schematic representation of the starting device of the carburetor of the family 1107010:
Explain the mechanism of the starting device. Pulling out the "SUPPLC", the driver as it leads the starting device into the corded state. Wherein:
- The three-blind lever "shares" the cable counterclockwise;
- Carries telescopic traction;
- The thrust, in turn, rotates the air damper through the lever.
- The second arm of the lever presses the axis of the throttle valve 1 of the camera.
- Airflow valve is now completely closed, the throttle of 1 camera is a slightly rinked for starting, creating a starting clearance
When adjusting the starting device, you first need to remove the carburetor. Then:
Turn the air flap lever so that it closes. Now the device "crushed".
View from above:
Now you need to flip the carburetor, measure the gap between the edge of the throttle of the throttle (1 chamber) and its wall. For the carburetors "Seven" this gap is 0.85-0.9 mm. The gap can be measured with a dipstick with a calibrated wire:
To bring it into this range, the drive thrust on the throttle is valued.
After that, set the gap "A". It is located between the canal wall and the edge of the air damper below. To do this, we repeat the damper, "we," the device. To create imitation airproof, blend the starting device stock:
Now the rod pulled the thrust of the slot, and the result is a damper. The clearance "A" is 5-5.4 mm.
To adjust this gap, you need to twist the screw adjustment, only first removing the threaded plug from it:
How to put idling speed on VAZ 2107
At first, you need to make sure that the ignition system is properly configured, all the wires are good and the engine is completely warm.
For this:
The meaning of this operation is to wrap the "quality" at constant "quantity" to 850-900 revolutions per minute.
It is possible to evaluate the turnover by an electronic tachometer, when skilling on a hearing, or by tachometer dashboard.
The next step is adjusting the air damper drive.
If you do not pay attention to the drive position, then the car can stuck. This will require a simple slotted screwdriver, and the key is 7 mm.
The figure shows the position of the flap with a recessed and elongated "SUMPLE".
For adjustment, we do the following:
- "SUPPLY" is drowned;
- Screw fixation of thrust turning out the slotted scope (spring pushes it vertically)
- Tighten the screw;
- Check the progress.
Adjust the throttle drive (GAZ).
If this drive is incorrectly configured, the acceleration dynamics and engine ticking deteriorate. This setting must be performed with an assistant.
It will take the horn key to 8, dumping, flashlight and caliper.
Completely "stream" "SUPPLC", or the drive of the air damper.
For adjusting the calipers, measure the length of the thrust, should be exactly 8 cm. With the help of rotation of the tips "Customize" the length of the thrust to this size, unscrewing the "ratios" nuts.
After that, put the craving in place and repeat the check. Modern thrust are often performed from a very bad plastic, which gives shrinkage. Therefore, it is necessary to check the "acquisition" of traction in a week.
You can not know how to adjust the carburetor of the VAZ 2107, but each can set the length of the thrust.
We only reviewed some of the opportunities to perform the adjustment of the carburetor with your own hands. In general, there is a whole profession of the "carburetor", which implies the full possession of this desired and complex technology. In one article, it is simply impossible to describe all the newances of this process. But we hope that the basic principles were clearer for you and helpful.
