The inkjet pump is made in the form of an injector, the flow channel of which is connected to the drain pipe, which comes from the engine, and the injection channel - to the pipeline of the left tank fuel supply.
Only in Hanter inkjet pump is built into the fuel module cover.
Fuel tanks, equipped with plugs for draining sludge, are located on the left and on the right between the longitudinal beams of the frame and the side panels of the body.
On vehicles equipped with an injection engine, a fuel supply system without a fuel tap shift crane is applied. The absence of a crane eliminates the possibility of violation of Tolivopodachi due to the late switching it.
The fuel pump fuel comes from the left tank through the receiving pipe installed on the fuel level sensor. As the fuel consumes, the right tank is automatically replenished from the left due to the resulting vacuum, since the right tank is not reported to the atmosphere, and the left fuel tank is communicated with the atmosphere through the valve separator. Thus, in the presence of fuel in the right tank, the flow rate is initially mainly from the right tank.
The excess fuel, the fuel pump vested back, enters the right tank through the fuel drain pipeline.
The plugs of fuel tanks of fuel tanks are deaf, provide a hermetic seal, eliminate possible leakage and evaporation of fuel.
It was not there, it was not to provide the corks of hermetic seal and gasoline runs from the neck of the right tank.
The lids themselves are made with ratchets, which does not give the possibility of tight closing the tank rigs.
How to deal with it? - Plant Manufacturer That Beach Ulyanovsky completely refused to answer the assigned technical question, swelling to the official dealer. (Cranks on the letter M).
Take the Lovato electric valve from the gas equipment of cars (it just serves as a gasoline compartment).
You can use manually by screwing up the bolt to the end, we open the valve, turning closing.
We install on the tube tube from the left tank.
It turned out not so hot, but it works fine, you need to buy adapters at an angle of 90 degrees, otherwise such loops turned out, in short, it is impossible, because the hose is blocked.
And so, the problem is solved and tested.
Maybe patent to arrange?)))
The continuation did not make it wait, the hoses are temporary phenomenon, all the same the inflection is formed.
From the morning, 3 degrees of frost, the sun shines, it falls on the head from the roof of a car fluffy snow, flowing with a light blow, my design thought works))).
To implement this idea, it took, a little less than half the meter of the copper tube 8 mm, a set of fading 5/16 with pipe cutter and pipe bender for copper tubes 6-8-10 mm.
On CMZ-409 Hunter, EURO-2 was used with a fuel power supply system without a fuel tank switching tap. Fuel supply is carried out by a submersible electrical displacement (submersible module) installed in the right fuel tank.
Fuel supply system SMZ-409 engine on UAZ-315195 Hunter.
Fuel tanks, through a fine filter fuel fuel enters the fuel raver, the relative pressure in which is supported by the pressure regulator at the level of 300 kPa. Increased fuel pressure eliminates the appearance of air bubbles and gasoline vapors in the fuel line, which interfere with the normal operation of the nozzles.
Fuel nozzles are high-speed accurate valves (normally closed), open, injecting fuel into the inlet tube of the engine. Opening-closing the nozzles is automatically carried out by cyclicogram of the corresponding output channels of the electronic control unit.
The nozzles are injected into the fuel to the hot and closed inlet valves of the engine, which improves the quality of the fuel-air mixture. The duration and phase of the fuel injection unit, the control unit establishes depending on the mode of operation of the engine, crankshaft revolutions and load.
Excess fuel in the ramp is reset through the drain hole of the pressure regulator and the inkjet pump into the right tank. At the same time, the fuel through the injection flows from the left tank through the inkjet pump into the right tank.
After any service on the maintenance or repair of the power supply system, the fuel of the ZMZ-409 engine associated with pulling the connections, removing or replacing parts and nodes is necessary to check the tightness of the system.
Not tightness in the compounds is eliminated by tightening the compounds or replacement of defective elements. Tightening of steel fuel pipe fittings should be made by a point of 27 + -7 nm. The tightening of the rubber hose clamps is made by 3.5 + -0.5 nm.
Signs of the malfunction of the power supply system of the ZMZ-409 engine.
Clogging of the mesh filter of the submersible module in the right fuel tank, the filter of fine fuel purification, the presence in the fuel tanks of dirt and mechanical impurities is manifested in the deterioration of the car dynamics, the unstable operation of the engine primarily on large loads.
With these features, in order to avoid the failure of the submersible module and fuel, it is necessary to immediately rinse the right fuel tank and the mesh filter of the submersible module, as well as replace the fuel purification filter.
At ambient temperature below 0 degrees, signs of clogging may be due to the presence of water and its freezing in the power system. When the water is detected in the fuel, it should drain it and rinse fuel tanks with pure gasoline fuel pipelines, and replace fine fuel filter. If, after the specified measures, the nature of the engine work has not changed and the unstable operation of the engine is observed, then the following works must be carried out.
Fuel tanks UAZ Hunter.
The power supply system UAZ HANTER includes two two-way fuel tanks. Each capacity is 35 liters. Maintaining fuel tanks consists in periodic flushing or replacing the filter of the submersible module in the right tank, flushing the filter of the fuel level pointer in the left tank and the tanks themselves. Periodically check the reliability of the fastening of the tanks and, if necessary, pull the bolts of their fastening. For flushing fuel tanks, remove from the car.
Flushing of the filter of the submersible module or receiving tube of the fuel level pointer can be produced, without removing the tank from the car, while the submersible module or pointer remove through the hatch in the floor floor.
Tubes of fuel tanks must be kept clean and ensured that they are tightly closed. Catalog number of hermetic tube fuel tanks UAZ HANTER - 31602-1103010. Also on fuel tanks are suitable corks 2108-1103010-11, provided that they are fully sealed.
In order to reduce emissions into the atmosphere of fuel vapor on UAZ HANTER vehicles, the fuel evaporation system is installed. The left fuel tank is communicated with the atmosphere through the separator, valve and adsorber.
During the operation of the car, you need to pay attention to:
- The presence of a sharp smell of gasoline in the cabin, the pumproom space in the location of the fuel and aircraft hoses and tubes. If it is presented, replace the adsorber;
- the correct installation of the electromagnetic valve of the adsorber purge;
- cracks and damage to the adsorber - if they are presented, replace the adsorber;
- Press and damage to fuel and steaming hoses, damaged and leakage tubes and hoses must be replaced.
Fuel ramp.
Designed to connect the fuel line to the engine inlet path and to install the nozzles. The fuel ramp is a through pipe with four holes for connecting and fixing the input fittings.
On the one hand, the pipe is connected to the supply fuel line, on the other, the drain fuel line with the fuel pressure regulator. Output fuel fittings Bosch 0 280 150 560 or Siemens 6354 ZMZ DEKA1D through sealing rings are pressed with fuel ramp to the holes in the cylinder head.
Filter of fine fuel purification.
The fuel system is equipped with fuel filter. It is made in the form of a disposable non-collapsible filter-cartridge. Make a fuel filter replacement every 20,000 kilometers or in case of faults mentioned above.
Bosch DR-L 0280160258 fuel pressure regulator or analog it.
Designed to maintain a constant fuel pressure in the fuel ramp and the bumpy space of the inlet tube. The fuel pressure regulator consists of the following elements: a housing with a pressure chamber, input and output fuel fitters, a fuel feedback valve, fixed on a diaphragm, and a vacuum chamber with an air vent.
The fuel pressure regulator is attached through the input threaded fitting to the drain hole of the fuel ramp, and its output unit is connected through the drain pipe with the inkjet pump. The air fitting of the fuel pressure regulator is connected by a thin rubber hose with the fitting, screwed into the inlet tube receiver.
Increased fuel pressure, more than 300 kPa, in the fuel ramp of the engine is manifested by increased fuel consumption, smoky engine exhaust. With these signs, it is necessary to clean the inkjet pump, blow the drain fuel lines from the pressure regulator on the fuel rail to the right tank. If necessary, replace the pressure regulator and electrical displacement.
The fuel system of the fuel of the ZMZ-409 engine on the UAZ HANTER is equipped with an inkjet pump. It is intended for forced fuel pumping from the left fuel tank in the right. The inkjet pump is an injector, the flow channel of which is connected to the fuel drain pipe into the tank, and the injection channel to the fuel supply pipeline. Fastened on fuel hoses at the right side member frame.
Periodically check the tightness of the pump and its connections. In the absence of fuel pumping from the left fuel tank in the right, remove the inkjet pump and remove it to the nozzle, rinse it with clean gasoline and blow with air.
The fuel refueling fuel is carried out separately to fill the tanks completely: the main tank is fixed at first (during the refueling, the fuel is also partially overflowed into the additional tank), then the additional is refilled. The fuel is consumed from both tanks about the same, the tanks work as reported vessels.
Installation requirements:
- Main tank cover ( without a valve, ATM access. There is no air to the tank through it)
- Additional tank cover ( with valve, ATM access. air in the tanks is carried out through it)
- Fuel Accessor of the main tank (overlap the tank message with the atmosphere, the "AIR" tube).
Supplement: At the SCANIA (by theory), an additional tank is spent at first due to discharge, and then the main fuel tank.
Advantages of the system:
Easy to install this connection scheme. No need to purchase a fuel on an additional tank. There are no additional connections to the car's fuel system - respectively, there is no likely to make it. Simplicity and reliability of the system functioning.
Disadvantages of the system:
At very low temperatures, there is a chance of freezing fuel in banjo bolts and a overflow hose, which will lead to the impossibility of flowing fuel from the tank to the tank and the pressure equilibration in the main tank with atmospheric. If the main tank is closed as sealed as possible, and the pressure in it cannot equalize with atmospheric - the external squeezing of the tank will occur. The tank will shrink inside. With a large number of compression and rally cycles, the main tank can crack. To avoid this, when the hose is freezing, it is enough just to open air access to the tank: open a tank message with an atmosphere through the fuel receiver (AIR tube) or installing the cover from an additional tank ( with valve, ATM access. Air in the tanks is carried out through it).
