The night is peaceful.

Qin Feng was lying on his comfortable Simmons bed, tossing and turning and couldn't sleep, he actually had insomnia!

Zhao Jiao lay quietly beside him, in the dark, with a pair of bright eyes, long eyelashes kept blinking, and finally couldn't hold back.

"Brother Feng, are you worried about the requirements of these leaders?"

"No, it's mainly for our future."

The performance of the J-8 carrier-based aircraft is too poor, at most it solves the problem of whether it has or not, and it cannot be used as a carrier-based aircraft as the main force of the navy at all, not to mention that it is also looked at by the Americans, as for the air force, it also needs advanced carrier-based aircraft, and the navy and air force have this demand, is it a few years to wait, or is it now......

It's hard!

Qin Feng has always been like a fish in water when he came to this era, and this is the first time he has encountered something that he finds difficult.

"Brother Feng, you are so hard, I ......" Zhao Jiao paused and continued: "Later, you and Liu Lao Lin applied for 10,000 tons of flour, also for our future, right?" ”

Qin Feng has recently begun to lay out, and asked Li Runzhu to help coordinate 10,000 tons of flour, and now he has coordinated 10,000 tons with Liu Laolin and them.

Such a big deal must be for the future.

Qin Feng blushed slightly, this, of course, is to use the advantages of the reborn to make a lot of money, you need money everywhere, and you have to find a way to make money, but you are a little embarrassed to make your own people's money.

"Forget it, don't think about it, there must be a road before the car reaches the mountain." Qin Feng said: "Gillian, Zi said, there are three unfilial pieties, no queen is the greatest, we ......"

Zhao Jiao was stunned for a moment: "Brother Feng, it will take some time for the Mercedes-Benz test over there, do you want to take advantage of this time to go to Eritrea to have a look?" ”

Mercedes-Benz's 500-hour long-life test took about 20 days, and during this time, the exhaust emission system was also tested simultaneously in Europe.

The technicians of the Mercedes-Benz Heavy Truck Factory and the technicians from Dongfang installed this high-tech exhaust pipe on their own heavy trucks.

"This is our most advanced NG85 heavy-duty truck." Retzker, an engineer at Mercedes-Benz Heavy Truck, said: "It is the most advanced heavy-duty truck in the world, and it uses a V8 engine that can output 375 horsepower. ”

"It's our most advanced exhaust pipe." Dangwei is also very generous: "Installing it in your most advanced engine can reduce its exhaust emissions by 90% and protect our blue sky, by the way, this is turbocharging, right?" We've got another system for you, which is being tested in our country, and the self-priming engine can reach 340 horsepower. ”

The technology of the engine is constantly improving, the engine with a displacement of nearly 15 liters, with the help of a turbocharger, can output 375 horsepower, which is already very strong, but compared with the self-priming 340 horsepower, it is not fragrant in an instant.

Retzke originally wanted to show off to these Orientals, but for some reason, he found that he couldn't show off, knowing that he was the strongest car factory in the world, why couldn't he put on that arrogant posture in front of the Orientals?

Squeak squeak...... The sound of the electric drill sounded, and a companion brought by Da Dawei began to drill holes in the girder of the Mercedes, and then installed the urea tank, looking at this thing, Retzke became curious again: "What is this?" ”

"Pee...... cans, if you want to reduce emissions, you need to add urine. ”

Da Dawei originally wanted to talk about urea, but he was afraid that it would leak secrets, after all, the big guy started as a copycat, and now he has to guard against others copying us.

He said it simply, but the little girl in charge of the translation was so blushing and thick in her neck that she looked at Pangwei with complicated eyes, and Pangwei stiffened: "It's not obscene, this is technology, tell the Germans." ”

Hearing the translated words, Retzke's eyes widened: "Really? ”

"Whether it's true or not, we'll find out until I've tried it."

Anyway, this jar is black, and you can't see the color of the liquid inside, so when it's time to test, quietly find an opportunity for no one to add a special urea liquid to it.

At that time, after the start of the fifth national number, many cars were loaded with urea tanks, but because it had just been promoted, many places could not buy urea for cars, so some people used their brains: can the agricultural fertilizer urea be used as car urea?

The answer is no, because the fertilizer urea contains too many impurities, which will lead to poisoning of the exhaust system, even if it is really used, it must be processed: dehydration, washing under high pressure, decolorization, deodorization, deionization, and adding high-quality pure water to make automotive urea.

Since there is no production of auto urea, they brought a few cans of processed urea themselves, which is top secret and cannot be known to the Germans. It's like urine.

However, in the eighties, Westerners still had principles and bottom lines, they were arrogant, and they themselves would feel ashamed to let them copy the technology of the East, so Retzke was just surprised and did not use his brain.

Finally, the exhaust system was retrofitted, and urea for cars was added. Several people from the East gathered around it, for fear that the Germans would see it and make Retzke scoff.

"Okay, now start the engine." Retzke said, pressing the start button on the side, this simple action stunned the buns from the East, didn't the engine have to be in the cab?

The cab of a heavy truck can be flipped forward, so that the engine under the butt can be exposed for easy maintenance, but what if the repair is done and the car is to be tested? Put the cab down and start the engine? What if adjustments are needed? The cab needs to be raised again!

At this time, there is no electric and hydraulic flipping, and the cab is pressed down by the handle, which is a manual work, so Mercedes-Benz heavy trucks have prepared two sets of starting systems, which can be started directly next to the engine, which is simple.

The engine was running normally, there was nothing unusual, smoke coming out of the exhaust pipe...... Not visible to the naked eye.

"Okay, put down the cab, let's drive the car to the exhaust gas detection agency." Retzke said, put the cab, just when the cab was just flattened and locked, Da Dawei opened the co-pilot's door, jumped on, and several people he brought also jumped on the back girder.

It was a tractor, there was no body, only girders, and they were just squatting on it, looking very nervous.

They have to make sure that the exhaust system is in front of them at all times!

Retzke sighed: "Guys, we'll be followed by a car, and you can see it when you sit in the back." ”

"No, we'll have to keep an eye on it."

Sitting in the back car? What if they are separated along the way?

"We don't allow that here."

"Why?"

"Because this is not a place to sit ...... people, if there is an accident."

"We are not afraid, there is an accident, life and death are fateful."

Retzke is completely speechless, how can these Orientals be dead-headed?

Fortunately, the exhaust gas detection agency is not very far away, and when the car drove in, the eyes of the people inside were wide-eyed, how could this truck be loaded with people, and there were so many people? Hey, how did these people jump straight out of the car they were driving? Is this making a movie?

"Koscher, turn on your equipment and check for the exhaust of our car."

The person in charge named Kosher got busy, connected the thick pipe to the exhaust pipe, and then activated the equipment.

"Okay, come on!"

"Throttle to the end!"

"Strange, it's so weird, wait, you guys turn off the fire first."

The roar of the engine disappeared, and Retzker's eyes looked at Kosher curiously: "What's going on?" ”

"Damn, the chain fell off at the critical time, our instruments are broken."

"Broken? What's wrong? ”

"It can't be detected, the NOx detection value is an order of magnitude worse, it must be our instrument malfunctioning, you wait, we have to re-debug."

An order of magnitude worse? Wouldn't that reduce NOx emissions to less than 10 percent? Retzke was suddenly excited, if it wasn't for the breakdown of the instrument here, it was his own exhaust system!

Although the East is backward, it is possible that it is outstanding in certain aspects.

Kosher tinkered for two hours, his hands covered in oil.

"Okay, this time it must be fine, you start the engine." Koscher's gaze looked at the meter again.

"Add half the oil!"

"Full throttle!"

"Oh, go to the ground, what the hell is going on!" Kosher felt like he was about to collapse: "How is it possible that the equivalent of nitrogen oxides emits only 35 milligrams per kilometer!" This set of instruments is the most advanced, how can it not be accurate? ”

"Kosher, is there a possibility that your instruments are accurate, that our emissions are more advanced?"

"How is it possible, at this stage, normal vehicles are 600 milligrams of emissions, if you only have these, wouldn't it reduce the pollutants by about 95 percent?"

It's 90 percent, but it's actually even better, 95 percent!

"Now, let's remove the exhaust pipe, and you can test it in front of the exhaust pipe, and you'll know."

The first installation is the most complicated, but after the installation is simple, it is simple to disassemble, just just run at high speed, the exhaust pipe is a little hot, wait for half an hour, after the exhaust pipe is at room temperature, the big guy divides the exhaust pipe by two, disassembles the exhaust pipe, and connects the exhaust gas detection device directly to the back of the engine.

Starting again, gas pedal, and looking at the display on the gauge, Kosher finally breathed a sigh of relief.

"This test is working and it looks like our instruments are not malfunctioning!" Kosher sighed: "However, your exhaust pipe is so powerful, how can you reduce exhaust emissions so effectively? ”

"Of course, we at Mercedes-Benz value these very much, and we want to protect the same earth!" Retzke said proudly, with excitement in his heart.

Well, it's great, from now on, we don't have to worry about exhaust emissions, we bought this patent from the Orientals, and our Mercedes-Benz trucks are clean trucks! Yes, after we go back, we will hold a press conference to announce the good news to the whole of Europe, and those environmental protection organizations will definitely praise us, in Europe, environmental protection is the highest priority!

On that day, the whole of Europe was in a sensation, and countless reporters rushed to the headquarters of Mercedes-Benz heavy trucks to shoot wildly at the truck with special exhaust pipes, while Retzke excitedly introduced the technology next to him.

"We use the latest SCR technology in the engine of this truck, which is ......"

The only fly in the ointment was that there was an Oriental standing next to the truck, this Oriental kept his eyes on the exhaust pipe, to see if it was okay, if anyone wanted to touch it, then he would say something to stop it, although the reporters were very upset and asked to drive him away, but Retzke just changed the subject awkwardly.

Environmentalists gathered outside the headquarters of Mercedes-Benz heavy trucks, holding small flags and shouting slogans, and this spectacular scene quickly spread all over the world.

At this time, Qin Feng had re-set foot on the land of Eritrea, looking at the newspaper that passed the boring time during the trip, Qin Feng couldn't help but sigh: People can't eat too much, and if they are full, they have to vent their excess energy.

"Qin, I heard that your Pacific Group has developed and grown again, and you still want to cooperate with German Mercedes-Benz, you must be very busy, right?" On the wide warrior car, Mu Latu and Qin Feng said.

The Warrior has become the most popular vehicle in Eritrea, but unfortunately there are not many of them, after all, there is no mass production and Eritrea is not well funded.

The first route between the East and Eritrea has been opened, after all, with the development of here, the two sides are getting closer and closer, and there are more and more people coming and going, but you have to wait for time, only one flight will fly a week, and if you miss it, you can only wait another week.

Hearing that Qin Feng was coming, Mulatu personally came to the airport to greet him, at this time, the car was driving on the rolling mountain road, looking at the scene on both sides, Qin Feng had an indescribable feeling.

Eritrea is just the beginning, and the cause of the Pacific Group is to spread to the whole of Africa, where it is poor and backward, but there are resources here!

At this moment, a familiar car appeared in front of it, without a hood, and the single-cylinder diesel engine poked there, looking very conspicuous. Behind the steering wheel was a sunspot, and while driving, he was still singing something in his mouth.

Sou! The car whizzed by.

"The railway capacity is insufficient, and the iron ore on the side of the mine is piling up more and more, so let's use road transportation, the road we talked about last time is still being surveyed, and it is estimated that it will be repaired in half a year." Muratu introduced.

"Wait, there's a problem! Why don't I hear the diesel? ”

The car swished past, Qin Feng just glanced at it, didn't see it clearly, and only now did he react, and he didn't hear the unique abrupt sound of the single-cylinder engine!

Hearing Qin Feng's question, Mulatu smiled: "That's what you said, our drivers are all experienced veterans, they never start the engine when they go down the mountain, so they can save fuel, and the speed is very fast......"

What? Qin Feng's face changed instantly: "No, no, absolutely not!" This is a violation of safety rules! In the future, safety rectification must be carried out in the mining area! Descent must be carried with gears, with the traction provided by the engine ......"

Go down the hill to pick up the slipped slope, or fully loaded! What a nervous person would dare to do that!

People who drive a car can't understand the difficulty of driving a truck, the truck has a large load, the braking distance is very long, and if you step on the brakes, it won't take long for the brake pads to overheat, causing the brakes to fail. Therefore, if you encounter a downhill section, it is a ghost gate, you need to hang to a low gear, use the reaction force of the engine to provide resistance to the car, let the car go downhill slowly, and step on one or two feet to slow down when the speed is fast halfway, but you must not step on it all the time.

If it's a hilly area that alternates between downhill and uphill, you can do this, take off the gear, and you can sneak directly to the opposite side, but now it's dozens of kilometers of long downhill! The Badaling Expressway in the west of the capital is called the death zone, and it is because of the long downhill slope of dozens of kilometers that it has led to countless truck accidents.

These four are not like a single-cylinder diesel engine to change, the braking force of the engine is insufficient, and you should be careful when going downhill. Isn't Kuroko's life a fate?

"These cars are all modified with brake showers, and when they go downhill, they release water and pour it all the way to the brakes." "The brakes don't fail. ”

Okay, the brakes are all used! Qin Feng also sighed, this is the first initiative of the Oriental driver, since the brake will overheat after a few feet, then let's pour the brake drum with water! At first, the water tank was put on the top of the cab, and later, it was more creatively to come up with air push water, the water tank was made into a pressure vessel, connected to the air pump pipeline, and under the action of more than a dozen atmospheres, the water inside was sprayed.

But...... This also has a lot of defects, the water added in has impurities, which may block the sprinkler, plus the careless driver may forget to add water, and there is no water in the middle of the mountain road, which may be fatal!

At this moment, another four-car jumped down the hill in front of him, and the driver of the car, who was busy operating, stepped on the clutch with his left foot, wanted to put into gear, and braked with the engine, but there was a burst of rattling sound in the gearbox, and he just couldn't get in!

He pressed the brake with his right foot a few more times, but the brake still didn't respond, and when he looked through the mirror, there was already smoke on the rear wheel!

"Get out of the way!" Mulatu shouted.

Garr, who was driving, immediately hit the steering wheel to avoid it, watching the car whizz past him, and also saw the despair on the face of the black driver.

The car continued to jump down the mountain, and the right side of the road began to appear peaks, this road carved out of the mountain, on the right is a vertical cliff, which has been extended upwards for more than ten meters, and on the left is a cliff.

The sunspot driver hurriedly hit the direction, and the car began to rub against the side, leaving deep scratches on the side, which was there before, indicating that there were drivers who did this before.

He was relieved that the speed of the car began to decrease, but the next moment, a tom sounded and made him panic again.

The tires blew up!

This is the house leak happened to rain overnight! The car lost its direction, couldn't turn where it should have been in front of it, and went straight down the cliff!
