How to wash its hands of the injector nozzle

How to construct and operate the nozzle

Inside the case is an electromagnetic fuel injector needle valve. When closed, it is held by a return spring. When applying pulses from an electronic control unit (ECU) to the excitation winding valve opens. At this time, the fuel is atomized and mixed with air and burned in the combustor.

From the quality of gasoline atomization depends correct proportions of fuel mixture and its ignition. During normal operation of the fuel injector is crushed into small particles can be easily mixed with air and burns.

Why clogged nozzles

Impurities in the fuel, short trips and challenging operating conditions lead to the fact that on the needle and the inner surfaces of the nozzle are formed carbonaceous deposits. This plaque clogs the channels. The solenoid valve is opened for a long time and in the combustion chamber falls more gasolineThan you need.

All this leads to pereobogaschenie fuel mixture, and the deterioration of ignition misfire. Unburned fuel enters the exhaust system, and burns already inside the catalyst which is hammered and melted at high temperatures. Along with this engine power is reduced, knocking appears and increases fuel consumption and exhaust emissions.

How do you know that you need to rinse nozzle

Auto manufacturers recommend doing cleaning every 30 thousand kilometers. A problem with the nozzles prompt appropriate error on the onboard computer. The same diagnosis will fuel equipment in the service station.

But it is likely to need washing, regardless of the run, if at least three symptoms from the list appear in your car:

• bad start (especially in winter);
• unstable idling;
• reduction of engine power;
• slow acceleration;
• dips when pressing the gas pedal;
• increased fuel consumption.

How to wash its hands of the nozzle

Method 1: a fuel additive

The most simple and relatively mild cleaning method using special additives. More suitable for the prevention of the formation of deposits in the fuel system all elements - from the fuel tank and to the nozzles.

The disadvantage of these additives is that on cars with high mileage, they raise all the dirt from the fuel tank and piping. As a result of clogged filters and injectors themselves, which leads to even more disastrous consequences.

You will need

• Fuel additive injector cleaner.

How to do

1. Add the product directly into the tank before filling the proportions according to the enclosed instructions.
2. Operate the vehicle normally.
3. For best cleaning effect, it is desirable not to stand in urban traffic, and take a ride on the highway.

Method 2: flushing nozzles to the engine

This method is more difficult to clean, but also more efficient. It not only cleans the injector, but additionally raskoksovyvaet piston rings, and also enhances compression. Washing is carried out on a running engine that runs on gasoline instead of the detergent composition.

The main disadvantage - you can not control the quality of washing. Among other drawbacks can be identified ingress of aggressive substances in the exhaust tract and the potential harm the catalyst. After using some tools require replacement of spark plugs.

You will need

• Means for cleaning the injector;
• fuel filter;
• two-liter plastic bottle;
• wire;
• 1m fuel hose of 10-12 mm in diameter;
• 3 clamp diameter of 9-14 mm;
• The pin 2 of a tubeless tire;
• M12;
• screwdriver or a drill;
• 12½ mm diameter drill bit;
• a compressor for tires;
• spark plugs (unless their replacement is recommended in the instructions for flushing).

How to do

1. Drill according to one hole in the lid and bottom of a bottle. Set nipple cover with inside-valve. According nipple fluid will be supplied to the ramp.
2. The second pin assembly into the bore in the bottom. It will be needed later to pump air to create pressure.
3. Wear on the nipple in the cap one end of the hose, and a second set on the fuel filter housing according to rotation. Tighten the ends of the hose clamps. Wrap the bottle with wire, so you can hang.
4. Warm the engine to operating temperature and plugged. Turn off the fuel pump, removing the corresponding fuse.
5. Start the engine. Let it run to relieve pressure in the rail. Wait until the motor stops.
6. Disconnect the fuel supply hose from the mains, and connect to the filter improvised washing receiver. Pour into a bottle washing, close the lid and hang the hood.
7. If your car has a reverse fuel line, stop it with the appropriate screws in diameter and crimp the collar.
8. Compressor to inflate the air bottle until the pressure reaches 2-2½ bar.
9. Start engine and run for 15 minutes at idle speed while maintaining the pressure in the bottle at the same level.
10. Stop the engine and wait for about 15 minutes to all deposits otmokli.
11. Restart the engine and work out the remnants of the washing liquid, maintaining momentum within 1 000-1 500.
12. Remove the bottle cap of the return and connect everything in a normal mode. Do not forget the fuse.
13. If washing and aggressive acts on the spark plugs, replace them.

Method 3: flushing nozzles with the removal

The most difficult method, which involves the removal of the fuel rail and injectors. At the same time the most effective, and spot - no harm to others not of the system. To wash the simulated work nozzle, instead of gasoline carburetors used cleaning agent.

Among the few drawbacks of this method only the complexity of the ramp and the dismantling of the nozzles, as well as the need to replace the filter and the sealing rings.

You will need

• The aerosol product for cleaning carburetors;
• 5 mm³ syringe;
• 9-volt battery type "Crohn's";
• 1-2 meters of wires;
• doorbell or other non-latching button;
• 4 clips of type "crocodile";
• screw diameter of 4 mm;
• pliers;
• Kit nozzles (only the rubber ring and filter).

How to do

1. Remove the throttle assembly and the fuel rail. Disconnect the injector wires and remove them.
2. Pour some fluid for cleaning directly into the cap from the container and place the nozzle for 15-20 minutes to dissolve varnish. The same cleaner can be washed with throttle assembly, as he filmed.
3. Connect wires with clips battery contacts and a spray nozzle according to the polarity. Cut one of the wires and set the bell gap.
4. Make from the body of the syringe adapter, having put on the tube tip aerosol.
5. Remove the microfilter from the first nozzle, screw in the fuel passage and screw pull pliers.
6. Put the syringe to the injector from the sprayer. Push down on the cylinder valve with a cleaner and at the same time repeatedly press the call button.
7. Put the syringe to the injector from the back. Press down on the valve and intermittently press the call button until the liquid begins to be sprayed evenly torch.
8. Repeat the process from 5-7 for each injector.
9. With light tapping on the weight of the filter and replace the sealing gum.
10. Install the nozzle and the ramp in place, assemble the parts in reverse order.
