The first thing Xing Yu saw when he stopped the car was the long mimeograph on the back of the car.

Xing Yu's first reaction was an oil leak?

Continuing to check, the two secretly rejoiced that it was only the rubber of the fuel supply pipe of the diesel grid that was slightly deformed under the high temperature, which caused the diesel leakage.

Quickly solve the problem, the two of them are worried about diesel reserves, although this stage is not very long, Shi Hui is still full of fuel, which will cause the vehicle to be overloaded, but it can also avoid the situation that there is no diesel on the way.

After all, DMAX is alone, but without teammates to help, he runs out of gas on the track, and he can't push it off the track.

It's a pity that this oil spill incident directly overturned Shihui's plan.

"Brother Shi, on the way ahead, I saw a herdsman's gas station, otherwise, I'll take the oil drum and walk over to add a little more, and then you bring the vehicle over there, where can we replenish?" Xing Yu recalled the small supply station he saw on the track before.

This is also a benefit of the T2 group, those professional modified cars have particularly high requirements for oil products, and the general gas stations are unable to provide special gasoline.

However, the T2 class does not allow engine changes, which also gives vehicles in the T2 group the option of refueling at the local gas station.

After Shi Hui checked the reserve of the spare fuel tank, he agreed with Xing Yu's opinion.

There is a way to sharpen a knife and not cut wood.

Now there is still more than half of this stage to be completed, and there is more than 200 kilometers of no man's land ahead, if there is not enough fuel in the no man's land, the delay will be even more.

It's better to fill up now, as for the penalty time of the organizing committee, compared to the 100+ penalty time of others, the penalty time of a few minutes of driving off the track seems so insignificant.

The supply station is 2 kilometers away from the edge of the track, a row of low ground nests, which is a relatively simple way of living in desertified areas, and the digging method is relatively simple: dig a pit about one meter deep below the ground, so as to save the bricks of the wall, the shape is square, the area is about two or three meters, and the low wall of about half a meter is built with adobe or bricks around it, and a few rafters are placed on the top, and then a raft made of branches is set up, and then the roof is covered with grass blades and mud.

Diwozi can withstand the winds and sand that are common in desertified areas, and are warm in winter and cool in summer, but poorly ventilated.

When the frontier was liberated, not part of the construction corps lived in such buildings, but now it is rare.

The perimeter is surrounded by a fence of dry poplar branches, and a wooden board with the words "shop" and "refueling" written on it.

It was a simple supply station, and there were a few small stalls at the door, on which were mare's milk, camel milk, and all kinds of colorful stones.

These stones are not ordinary stones, although they are not as expensive as Hetian jade, but they are also worth a lot of money at present.

As for the oil, there are only two kinds of gasoline and diesel, and the label is not known to the owner himself, and the price is more than twice as expensive as the outside.

Originally, Xing Yu was worried that he would run into a black shop, but after a brief exchange, he found that the owner here was very enthusiastic, and he also knew that the ring tower rally was being held now, and several cars had already come to refuel before Xing Yu.

The oil is all packed in iron drums, which are sold by the pot, and the owner of the store said that a pot is two kilograms, and the large tank of DMAX needs to be filled with dozens of pots.

When Xing Yu cooperated with a little balang here to cheer, Shi Hui chatted with the boss with great interest about stones, jade produced in the frontier, including Hetian jade produced in the Hetian jade area and golden silk jade produced in the Karamay Wuerhe area of northern Xinjiang, and aventurine jade and Gobi jade produced in the Hami area of eastern Xinjiang.

After refueling, Shi Hui also bought a few pieces of jade and put them in the toolbox.

This is what Xing Yu was busy with just now and didn't find out, otherwise he must persuade Shi Hui well.

It's not too far from the finish line, and the straight-line distance to Xing Yu's house is no more than 800 kilometers.

Xing Yu's parents have nothing to do after they retire, except for picking mushrooms, they like to pick up stones.

Picking up stones is a process of enjoying nature, and in the Great Gobi Desert, which is boundless at a glance, it is a kind of release of various parts of the human body and emotions.

Although fine jade is not easy to find, general Gobi jade is everywhere.

In addition to exercising, some jade can also be sold for a good price, which is why Xing Yu's parents and most retirees are happy to do so.

"Brother Shi, if you want these things, go to my house, there is a yard, you can choose, what do you buy, who knows if these are true or false. On a big straight road, Xing Yu put down the road book and started chatting.

The next corner is still far away, the track is clear, and the sky is even more cloudless.

It's also nice to be able to talk about something else during the race.

"You tell me it's okay to talk about cars, you still know stones?" Shi Hui also said relaxedly.

"I don't understand, but my parents do, my old man scrapped a Nissan pickup in order to pick up stones and roots, and recently I was looking for an Isuzu pickup truck for him. Xing Yu continued.

"Isn't it? The car is all scrapped, how much jade do you have in your house? Shi Hui asked curiously when he heard this.

"It's all cheap stones, and there's no market, picking up stones is not to make money, it's just to exercise, the last time I went home, I couldn't put it in the basement, and some of the bad ones were thrown in the yard, not to tell lies, some of the ones thrown in the yard are better than the ones you just bought...... Left ten, 400, midline, open, full oil. Before the chat was over, after Xing Yu saw a strange stone on the side of the road, he immediately read out the contents of the road book.

Shi Hui didn't think about the stone either, and began to concentrate on the game.

Another big straight line, I don't know what the organizing committee thinks, there are a lot of big straight lines in this stage.

The large straight line is not friendly to the small displacement of the car at all, don't look at the DMAX is 3.0 displacement, but those professionally modified racing cars 6.2 displacement are disgusted with small.

With such a large straight line, pulling high speed, Isuzu can run at most about 140 kilometers per hour, but those professionally modified cars can run more than 200 kilometers per hour in such a straight line.

Compared with such a straight line, Shihui still prefers to challenge some tracks with many curves and complex road conditions.

The speed increased to about 100 kilometers per hour, and Shi Hui shifted into fifth gear, which took a lot of time to switch into fifth gear in this stage, and the previous three big straight lines were switched in this way, and this time the two felt that there was no problem.

But after the vehicle traveled a certain distance, the engine began to shake violently, and Shi Hui had to lower a gear, looking at it, there was no problem with the speed, not like the previous turbo pressure pipe problem.

After shifting into fourth gear, the jitter is reduced and the speed drops slightly.

As the revs increased, I shifted into fifth gear again and drove less than 200 meters, and the shaking continued......

"Thief, I trust him so much, he definitely has a problem selling my diesel, and when I get to the camp in a while, you can help me take a good look at those stones. When Xing Yu was still thinking about what caused the vehicle to shake, Shi Hui had already experienced in judging the problem.

"Is there a lack of cylinders, do you want to check the spark plugs?" Xing Yu subconsciously judged.

"Your diesel engine has a spark plug, it is missing a cylinder, it must be that the diesel fuel just added is not clean, and now it is a little blocked injector. Shi Hui glared at Xing Yu angrily.

A four-stroke diesel engine works on the same principle as a four-stroke regular gasoline engine: suction, compression, ignition (combustion), exhaust gases. However, a diesel engine does not breathe much the same as a gasoline engine in that it does not breathe in a mixture of fuels, but all air. These gases are strongly compressed in cylinders and can reach temperatures from 700C to 900°C.

At the end of the compression step, a small amount of atomized diesel fuel is injected into the hot air through the nozzle, and the mist begins to spontaneously ignite due to the high temperature, so the diesel engine does not need either a carburetor or a spark plug. The next steps are the same as those of a gasoline engine.

Looking at the principle, diesel engines do not need spark plugs, and fuel injectors are particularly important.

The fuel tank mouth of diesel fuel will be specially equipped with a filter, usually when refueling found that there are precipitation particles to be cleaned, once the filter is damaged, replace immediately.

In the past, when refueling, the team technician would even put a stocking on the refueling gun to ensure the cleanliness of the diesel.

It's just that in that small supply station just now, there are not so many conditions, and the refueling is poured directly from the kettle, so it is not surprising that such a problem has occurred now.

Diesel refueling is actually particular, 1. Refuel at a reputable gas station with guaranteed quality as much as possible.

2. Before refueling the fuel tank, purify the diesel as much as possible. The commonly used purification method is precipitation plus filtration, that is, it is precipitated for a certain period of time to remove most of the water and impurities with large particles in the oil, and then the diesel is filtered through two strainers: coarse and fine. That's why technicians used to put a stocking on top of the gas gun.

3. Pay attention to the correct operation of refueling, that is, the refueling pipe and the fuel tank mouth should be wiped clean, and avoid wind and sand; when filling, do not shake the oil drum, and the suction pipe should not be inserted into the bottom of the barrel; after the refueling, immediately cover the fuel tank cap. Just now, Xing Yu felt that the oil was too expensive, and he couldn't wait to pour out all the dregs in the oil pot, but he had actually made a mistake.

Stop, unload the diesel filter, sure enough, I found that there was some blockage, the diesel filter element of the DMAX is in the cabin, it is very convenient to replace, but no one thought that such a thing would happen during the race, there are many accessories for the racing lira, but there is no filter.

Fortunately, there is a bottle of carburetor cleaner in the car, which is a good thing, not only can effectively clean the oil sludge and other dirt on the surface of the throttle and engine parts, but can also be used as a loosening agent.

Spraying a little into the air intake when the vehicle is difficult to ignite can also help the vehicle start.

Hiding in the car, closing the doors and windows, Xing Yu took the diesel filter and sprayed a whole bottle of cleaning agent.

After washing and installing, Shi Hui sighed: "Eh, I forgot to ask my daughter-in-law for a few pairs of good quality stockings." ”

"Well, it's good to use it when you refuel, you don't want to put a stocking on the diesel filter. ”

In fact, the role of stockings is not only as simple as filtering, desert races, all vehicles will be equipped with wading hoses and sand cups.

Generally, the air intake of the vehicle is hidden in the cabin, and it is inevitable to suck in more sand and dust when driving in the wind and sand for a long time.

Many riders also put a stocking on the air filter and over the sand cup to prevent dust from entering the engine.

As for what Shi Hui said, putting a stocking on the diesel filter element is also a means that truck drivers often use to filter diesel......

After washing the firewood filter, the vehicle continued to shake after a long time, and the Isuzu that lacked a cylinder could only speed a little ROU.

Shi Hui didn't dare to step on the brakes easily, the speed increased, relying on the inertia of the piston, the vehicle power can also rush some small sand slopes, if you slow down, if you want to increase the speed again, you can only rub a little bit. Otherwise, a small dirt slope will allow the car to lie on its stomach.

This time it was really swaying out of the special section, the vehicle was driving frustratedly, seeing that the finish line was in sight, the organizing committee's maximum time had been exceeded, and it was inevitable to participate in the first penalty time of the ring tower......
