Masha took her Creta from repair. Bumper changed yes wing. And then the car stood for several days in the yard and got dusty. The girl decided to spray before the trip with a washer, clean the glass. Brushes go, the motor buzzes, and water does not splash! The smart Masha sacrificed a bottle of drinking water, added it to the washer, but it did not help. Calls father. He began to remember something about the valves on the G8, but he did not give any practical advice. And here comes a classmate in the yard, who has been working in a car service for five months already. And she screams from afar: “Masha, it’s good to breed damp! But you …"

And you guessed what was wrong with Creta? We are waiting for a detailed description of the malfunction and the system in which it arose.

What do UAZ and Titanic have in common? Expert Competition

Send the answer marked “Competition” until July 1, 2018 at the address: 107045, Moscow, Seliverstov per. 10 - or by e-mail: [email protected]. Indicate your contact phone number or other quick contact method.

We undertake to read all your posts on the topic of the contest. The prize will be awarded not only the correct, but also the most complete solution of the competitive problem with a detailed answer.

And now to summarize the “Expert Competition” from the March issue of the magazine “Behind the Wheel”

The hero of our task Stepanych acquired a used UAZ Patriot. And after I installed a bunch of utilities on the car, fuel flowed from the right gas tank. Readers had to figure out the reason. But, as you know, a short answer in the telegraph style is not enough. It is necessary to tell what and how it is arranged in the system, what the designers conceived and how the newly-made car owner managed to harm himself.

Not all readers remember the main rule of our competition. The task always contains comprehensive data in order to solve it. And how do you upset after that answers like these: "Most likely, the gas tank rubbed under the clamp that holds it. " The tank may be wiped, but such an event has no connection with the condition of the problem even closely. With the same success, it can be assumed that someone drove into the right side of the Patriot.

UAZ Patriot - 14 shortcomings and 9 indisputable advantages

Several readers sinned on a bottle with an octane corrector, which, they say, dissolved the gas lines. Friends, only in old action movies there are episodes in which the liquid shoved by enemies instantly dissolves the half-machine together with the driver. When replacing the fuel filter, you can nakosyachit, but most likely, because of this, the fitting will break. Or it will flow - again due to a poor landing - right after starting the engine.

But still, our readers love Russian technology, and therefore a lot of correct answers have come. The winner of the competition was the one who gave not only the correct, but also a detailed answer! We quote it below.

UAZ Patriot - an original car. This is known to everyone who owns it for a long time. For beginners, he sometimes presents inexplicable surprises. But it’s good that the owners of the Patriots are mostly sociable people and are always ready to share secrets and features of operation. So the neighbor Stepanych gladly helped him.

Many people know that on Patriot, before the restyling of 2017, two fuel tanks were installed. But only one gasoline pump located in the right tank is responsible for supplying fuel. It provides the flow of gas into the ramp at a given pressure. At the same time, the pump performance is several times higher than the engine's fuel needs. Therefore, there is always a "return" - a highway through which excess fuel is poured back into the tank. This flow also contributes to the transfer of fuel from the left tank to the right. How?

UAZ Hunter and Patriot: thanks, grandfather!

For this, an ejector (or, as it is also called, jet) pump is used. Outwardly, it looks like an ordinary tee, only inside there are processes described by the law of the Swiss physicist Daniel Bernoulli: the higher the fluid flow rate, the lower the pressure in it. Due to the pressure difference between the left tank and the diffuser cavity in this tee, fuel from the left tank begins to flow into the right. Such a system regularly fulfills its function until the hermetically sealed right tank is filled to the top: at the same time, pressure will rise in it and ejection will stop. If the right tank is closed leaky, then the fuel will continue to flow in - as a result, gasoline will flow out through the leaky plug. By the terms of the problem, the hero immediately filled both tanks to the brim. And since the abnormal gas tank cap was leaking, a leak arose almost immediately.

Owners of the Patriots, who want to protect themselves from theft of fuel, put lock plugs on their cars, getting the same problems with the flow of gasoline. After that, they return the native traffic jams to their place - and the system begins to work properly again. In order for everything to function as it should, the tightness of only the right tank is important - and you can completely remove the lid from the left, unless, of course, you are concerned about the possible ingress of dirt into it.

We can add that jet pumps work not only on UAZ SUVs. For many crossovers, the fuel tank located under the rear seat is almost divided into two volumes by a deep tunnel in which the driveshaft passes. And there, too, a jet pump is used to pump fuel - that's just that there are no problems with overflow.
