Rebirth of the Auto Giant

Chapter 540 Computer Diagnosis

Three red TC8×4 tractors were driving on the highway with containers. In the leading vehicle, Yang Haiquan was sitting in the passenger seat. Behind him was a berth where the co-driver slept and rested. Two people were fixed under the berth.

An oxygen bottle.

The driver, Lao Huang, looked ahead and said: "Master Sheep, there is actually no need for you to come here with us and suffer."

Lao Huang continued: "Running LS is different from other routes. The altitude of this route gets higher as you go west. People who don't walk often will have stronger altitude sickness in their bodies as the altitude increases, and their heads will feel like they're exploding.

I also have a splitting headache, especially when I go to bed at night, and it might be fatal."

"This is the main reason why we choose this route for testing our products. We just want to know what kind of problems the engine will have under hypoxic working conditions on the plateau. At the same time, the electronic control unit also varies according to different altitudes.

Record the status of the engine under the oxygen concentration, and I must personally follow it and check it at any time."

"We have also made full preparations for the occurrence of altitude sickness. I saw the two large oxygen bottles at the back. With their protection, there is no problem at all. Besides, the company has arranged for me to go to the hospital for a physical examination. There is no problem at all.

It’s a problem.” Yang Haiquan said.

"Haha, I didn't expect your company to do a very thorough job, but you'll know after a while. When I ran with the master for the first time, I had my first altitude sickness. It felt like life was worse than death. It was so painful that I just wanted to take it.

Hitting your head against the wall."

"Haha, I'll just take oxygen when the time comes, but I believe I'll get used to it soon," Yang Haiquan said.

"It takes at least a few trips to get used to it," Lao Huang said.

This time, the company also gave Yang Haiquan a high business trip subsidy. In the car, Yang Haiquan prepared milk, mineral water, biscuits and other backup food.

As the car slowly drove westward, the sights of Yanghaiquan that no one had seen before appeared in front of us. The clear blue sky was as clear as a wash. On the roadside, yaks swung their tails leisurely and ate grass, wearing Tibetan clothes.

The herdsman in costume swings the rope in his hand.

A Tibetan Mastiff, as powerful as a lion, followed the herdsmen, occasionally driving the cattle.

As the altitude continued to increase, Yang Haiquan observed the engine oil temperature, water temperature and other responses on the instrument.

"Master Sheep, don't worry. New cars, especially your Tang Dynasty-powered engines, will never have any problems. Not to mention your diesel EFI engines, even new traditional diesel engines have not had any problems. Don't worry, you

Go and rest in the back. I'll call you if you need anything." Master Huang said to Yang Haiquan when he saw that Yang Haiquan still didn't rest after running half the distance.

Yang Haiquan also felt that it made sense. He patted the right person on the shoulder and said, "Okay, I'll rest in the back. Call me if you need anything."

"Okay, I'll call you at the next resting point and let's have something to eat. You've never eaten yak meat, right? It sounds great, and the mutton here is also more delicious." Lao Huang said, and then asked Yang Haiquan to take it from one side.

Take out a box of CDs and play the songs.

The two set off from Shand in the morning and arrived at ls. Guman at 8 a.m. on the third day.

The first altitude sickness allowed Yang Haiquan to truly understand what the driver, Lao Huang, said about having a splitting headache and banging his head against the wall. Fortunately, the car was well prepared and had two large oxygen bottles.

When they arrived at the destination, Huang asked people to unload the cargo, while Yang Haiquan took out his laptop, plugged in a computer port in the cab and opened the computer-specific software to view various data of the electronic control unit.

At the same time, the driver Lao Huang asked curiously: "Master Yang, what are you...a computer?"

"Well, this is our company's laptop specially used to detect EFI engines. It is equipped with an intelligent detection system developed by our company. It can detect the engine speed, oil temperature, and water temperature." Yang Haiquan checked the computer while checking the computer.

While explaining, "It can also diagnose where the engine is broken and the computer can know it."

"What? Is it so advanced? Computers are used for diagnosis." Traditional diesel engines are not like this. They rely on the work experience of the master to make judgments. I didn't expect that the times are developing so fast, and now computers are used for repairs.

This would be really difficult for a master who doesn’t understand computers.

"Haha, it's not that mysterious. There are sensors on each component of the engine. For example, a sensor will be installed at the outlet of the high-pressure oil pump. If the oil pressure ratio setting data does not match the set data, the computer will diagnose the high-pressure oil pump failure, and the computer will display a

The code will be displayed on the computer. Once you check it, you will know that it is a high-pressure oil pump oil pressure failure. In the same way, there will be a sensor on each electronically controlled injector of each cylinder to accurately know the electronically controlled injector of each cylinder.

The oiler is faulty." Yang Haiquan looked at the computer and saw rows of codes popping up, all of which were normal.

"Master Yang, you just said that you can check the engine oil temperature and water temperature. Isn't there a thermometer on this instrument? Isn't there a thermometer directly on the instrument panel?" the driver, Lao Huang, asked doubtfully.

"Yes, but that's just a value within a range, not that specific." Yang Haiquan carefully looked at the engine oil temperature and water temperature at each time. These electronic control units have detailed information.

He pointed to the oil temperature record in the computer and said: "See, this is the oil temperature change under certain operating conditions such as engine speed, horsepower, etc., where the oil temperature fluctuates greatly. The oil temperature record above

Will be more detailed."

"Oh, it's true, this computer is really good."

"So the new EFI engine will have better emissions, noise, fuel consumption, and vibration than the previous traditional engine. This is the most cutting-edge engine technology at present and will be exported to Germany and other European countries." Yang Haiquan checked it out.

He turned on the engine, then turned off the computer and said: "Okay, there is no problem with the engine at present, everything is working normally." Yang Haiquan put the computer into the bag and said.

This computer is now worth more than 20,000 yuan. He has to keep it. If someone steals it, it will cost 20,000 yuan.

"I just said it's okay. Traditional engines have been running for several years without any problems. This new engine is so advanced and there are no problems with it. If you ask me, you can just lie down in the company. When we go back, you can do it again.

It can be checked," the driver Lao Huang said.

"You can't say that, but this is a new engine, and no one can guarantee that it will have any problems. It's like a new daughter-in-law, who is often more squeamish. I want to be with the car to deal with any situation that arises at any time, and I guarantee that you will

It is safe to use the car." When Yang Haiquan came down, the four other drivers from the other two master cars also came over, and everyone had a meal and rest at the "station" designated by Qinshan Company.

Generally, for long-distance trips, there are two drivers in the car.
