Injector Cleaning

I'm sorry for not perfect english. In time I'll do a good quality translate. If you could not get anything please feel free to contact me in comments. I will answer you as soon as possible.

The idea came to clean the nozzles for a simple reason: a machine weighing about a ton consumed nearly 10 liters of fuel per hundred kilometers as the city and on the highway. While the engine is running smoothly, without stalling, regularly pulling in any frost was got well and everything seems to be well in it. Based on the mileage of about 150,000 kilometers and the assumption that the nozzle was never cleaned (some knowledge of the past owner) decided to pull out and clean the nozzles. This, by the way, all of the machine mini One 2001 with the engine 1.6i.

The first step is to remove the nozzle. I will not describe in detail this process, I will describe briefly, disconnect the fuel hoses, disconnect all of which can interfere remove the fuel rail, remove the wires from the injectors, Turn off the rail and pulling it together with the injectors. She can sit tight, so do the operation carefully, but firmly.

If successful, continue to the previous action. To remove the nozzle from the rack to remove the retaining clip, it is a snap. Now, besides friction nozzle holds nothing and it can be pulled out, but carefully, because the fuel rail diesel, and the friction force is very well kept. With that had to suffer by pulling and twisting the nozzle.

Suppose managed. Now that the rubber seals are not affected by the chemistry they need to be removed. We get naked 4 injectors. They are all in the dust and dirt, so for a more enjoyable cleaning work I washed them with a sponge and soap, nothing of them do not, the only pure steel outside.

Preparation for cleaning

To clean the fuel supply high quality electrical components must pass through a nozzle cleaning fluid, and the fluid that Sia was able to move the nozzle would be nice to open it. To open I fashioned a pair of wires to the terminals on one side. Wore them to the contacts jets, signed by the way there positive contact. Filed for the opening of the nozzle with a battery powered radio from 6 volts, though, I think would be enough, and 3.7 volts from the battery of a mobile phone. And sure enough voltage from the charger of the same cell. He tried it, took charge with a round connector (just round easier to connect). It's easier than something to split hairs, using a car battery, including a lamp in series so as not to burn the nozzle ... It should be easier to do!

To summarize the liquid to the nozzle took the plastic tube slightly thinner diameter than the nozzle in the places which it is inserted into the rail and motor. This tube is used to divert water from an air conditioner using a pump. I took the remains, there are many do not. In general, you can use any as long as it can be put on the nozzle and the rubber is not desirable, because, for example, rubber carburetor cleaner eats.

Now I will describe the process that I did. To start using the tubes of the ordinary electric motor pump and a homemade device to open the injectors (pair of wires to the battery) drove through them 650th solvent. Put on to the nozzle tube, filled the tube solvent pump delivery pressure. By the way my pipe to the pump went perfectly well and it was fixed. Then, when fluid pressure is often the opening-closing nozzle, making a circuit, open circuit. I want to note that this process has been debugged is not the first attempt, there have been other experiments with different hoses. After repeatedly drove a small amount of solvent through all 4 injectors I have something not got the feeling that with the injectors all good now, so I put them in a glass nozzle down and filled with solvent to the nozzle disappeared, no more.

And as a solvent poured into each injector. Despite the fact that the nozzle closed solvent somewhere for 20-30 minutes fully emerged. All night they soaked and during this time the solvent was acquired slightly yellowish-brownish tint. In the morning I went to drive the solvent through them, and in different directions and without the pump, creating a vacuum mouth gaining the liquid in the tube through a nozzle and a similar method produced.

've Seen in a column of liquid typed small black particles, believing that it is chunks of dirt, which did not give the correct injectors to spray fuel. About an hour I got sick and had a feeling of cleanliness injectors, therefore it is time to go and put them in their place.

Assembly and the results

I put the O-rings are new, while the old ones were pretty decent (just before parsing ordered a new benefit they really cheap). Gathered in reverse order, and moving moment - to start the engine! I turn the key ... Starts immediately and runs as usual. And no better and no worse ... Why climb? But the result was seen later. The hostess informed that the machine was quieter and smoother to operate at speeds of about 3 million, was easier to go, and when driving on the highway at 300 kilometers left half of the 40-liter tank. That is, the flow around the track was about 6.5 liters, well, the city traffic jams on the order of 7-9, depending on the ratio of standing/riding. So no wonder climbing!
