Fuel pressure is an important parameter that needs to be constantly controlled. Its value directly affects the efficiency of the motor, its power and behavior in various modes. Consequently, every car owner who does not indifferently does the technical condition of its own car must periodically check the pressure. How to do it, read further in the article.

Fuel Rampa VAZ 2110 Device and Purpose

The fuel ramp (rake) is a mandatory element of the Fuel system of the DVS with a distributed injection. It is a segment of a hollow tube, the ends that are closed on both sides and are distinguished by the presence of taps for connecting a smaller diameter tubes. Through the data of the tube fuel flows to the injectors, which are located on it. In addition, there is a pressure regulator on it. The fuel that falls inside the ramp moves by means of nozzles into the inlet tube. In addition to the discharge tubes, there is also a locking fitting and a hole in this design.

How to check the pressure in the fuel ramp, methods of checking

You can measure this parameter by several methods. One of the most common is the acquisition of a special set, which includes a special adapter for connecting, a pressure gauge (it is due to the measurement of it) and drain. For the purchase of these devices, it is necessary to allocate about 1500 rubles. But you can do differently - go to a hundred, where experts for 300-500 rubles. Required measurements.

However, there is a more sophisticated method that does not require additional costs - it is possible to measure fuel pressure using an ordinary pressure gauge used to test the pressure in the tires. At the same time, it is advisable to use a pressure gauge for measurements, the limit of which is minimal (approximately 6-7 atmospheres). This will minimize the error.

How to check the pressure in the fuel ramp using a air pressure gauge for measuring tire pressure

Sequencing:

1. We prepare the pressure gauge and wind the fum-tape right under the nozzle.
2. We prepare the oxygen tube with a diameter of 9 millimeters and put it on top.
3. With the help of a clamp from two sides, fix fasteners.
4. To avoid fire, cover the generator with something.
5. Next, it is necessary to reduce the pressure in the system to a minimum. Make it easy. We remove the fuse that feeds the fuel pump (on the VAZ 2110 it is located near the control unit, under the cladding, is the extreme on the left side), we start the motor and wait until it stalls.
6. Twisting plastic cap, which is installed on the fuel ramp.
   
7. Look inside the cap - there will be a nipple and a standard hole. Take the cap from the wheel and unscrew it. Be prepared for a non-essential fuel release, which is due to the presence of residual pressure.
8. Then we put on the output of the ramp the second edge of the hose and fix the clamp.
9. We remove from the "Protection" from the generator and start the motor. However, do not forget to return the fuse in place.

This method of fuel testing is one of the simplest, accurate and very effective. By the way, if there are no clamps, special bushings of the bolts for adjustment can be used for tightening. At the same time, for the purpose of fixing on the fitting it is necessary to wear a small rubber ring.

What pressure in the fuel ramp VAZ 2110 is considered the norm

Normal fuel pressure must be 2.8-3.2 bar (atmospheres). If you remove the vacuum tube from the pressure regulator, the indicators may insignificantly grow (0.2-0.7 atmospheres).

Safety and fire safety rules for work

Be very careful when working. To avoid ignition, be sure to cover with something generator.

Tools, fixtures, consumables

1. Hose.
2. Manometer.
3. Stub.

How to check the fuel pressure VAZ 2110 engine 1.6 without reverse, checkout (step by step)

On the VAZ 2110 volume 1.6, the pressure indicators in the fuel ramp are unchanged and vary within 3.6-4 bars. Measurements are often performed according to the same principles as described above. However, there are several other non-standard techniques.

Method 1:

1. We prepare the above-described design - the hose on the end with a pressure gauge.
2. The diameter of the hose should be approximately 8 millimeters.
3. Measurements are made at the output from the fuel pump module.
4. A pressure equal to 5-7 atmospheres is considered to be a normal parameter.

Method 2:

1. Recall how the return on the engines with the drain ramp closes. It is better to join at the same time right on the fuel pump.
2. Double hose should be dismantled and insert a plug (instead of the plug, you can apply a "nipple" from the fuel filter).
3. Tension single pipe to the pump fitting. Measurements are made directly at the ramp.

Tips Prof.

It is important to remember that problems with the fuel system are usually manifested by sharp "dips" during the achievement of high rotor of the engine. In addition, when driving a car can pull, it is tupit when setting speed and so on. In this case, it is necessary to check the pressure. Only after that you can detect the main reasons for problems - gas station, nozzles, filters and so on.
