Rebirth of the Auto Giant

"Brother, this... only the two of us can go there, can it be done? This is not as simple as maintenance. The engine is not running now. Who knows what the problem is." On the way to Luoyang, Guo Yuquan thought about the time when he was about to pass.

There was a Yigong zl40 loader parked at that time, waiting for the two of them to go over and repair it.

Guo Yuquan is now like a small boat drifting on the sea without a lighthouse, rising and falling.

"We are the closest here. Only the two of us can go there the fastest. The master is away on a business trip. Several apprentices are here who are at the same level as us. The users can't wait. Let's go there first to see the situation before making a decision. If it doesn't work, let the master

Come here." Duan Luanhong said.

When Guo Yuquan heard that the two of them couldn't decide, he called the master over, and he felt more at ease, "Okay, this is the only way."

That afternoon, the two arrived in Luoyang, checked the address given by Gao Yaya and found their destination.

This is a sand field, selling a Yigong zl40 loader to load sand into the vehicle.

Hearing that the master was coming, Shachang sent someone to pick them up.

On the way to the battlefield, there were rows of Jiefang trucks waiting to be loaded, including many bright red Tang Dynasty heavy trucks.

"You're finally here. Look at the queue for this bus. It's so long. Just come over now." The driver said.

Duan Luanhong also took the opportunity to inquire about the fault situation. The director did not listen too specifically on the phone, "What's wrong with the car?"

"Anyway, it won't start now. It makes a loud bang when I hit it and it just won't work. When I bought a new car, when I handed it over, the salesperson said that if there is a problem with the engine, don't let outsiders fix it. You must let it be repaired by you."

, otherwise the manufacturer has the right not to be responsible for the three-guarantee service. Now the car does not dare to move. It has been parked for a day and a night. Look, there are long queues for Lasha's cars." The driver said while driving.

"Master, why are there so many cars and why is sand so in demand?" Guo Yuquan asked.

"No, sand is in hot demand now. Houses are being built and infrastructure is being built everywhere, and the demand for sand is very high," the driver said.

Soon, the two arrived at the battlefield and saw a brand new yellow Yigong zl40 loader parked there, with a long motorcade behind them.

Duan Luanhong and his wife put on their "Tang Dynasty Power" one-piece overalls and started working.

Duan Luanhong found the driver and asked about it.

Through the driver's narration, the two people roughly understood the process of the failure.

The car has been emitting white smoke in the past few days. I didn't pay much attention to it at first. I thought it was because it was new before. There was white smoke when the car was cold and it disappeared after the car was warmed up. But strangely, it happened just a few days ago.

The white smoke did not disappear. Due to the tight work schedule, I didn't pay much attention to it until yesterday at noon when the car started, it made a buzzing sound but could not start the ignition.

"Master, what is this problem? Is it serious?"

"When will it be ready? We still have many cars waiting to be filled with sand."

The truck drivers who were waiting in line at the battlefield saw people coming from the manufacturer, and they all came over and started asking questions.

"Don't worry, since we are here, we must be responsible to the end. Our Tang Dynasty Power Company will not be irresponsible." Guo Yuquan said, patting his chest.

"Shut up!" Duan Luanhong was really angry when he heard his junior brother assure the user. It's true that a dog can't change its habit of eating shit.

"What's wrong, senior brother? What did I say wrong? Aren't we here to deal with it for users?"

"You're right."

"Then you still scold me?" Guo Yuquan didn't wait for the other party to finish speaking, and said as if I was wronged.

"The situation is not clear yet. Is it caused by our quality or the other party's improper use? You can boast to users now. If it is not a quality problem later, what will you do then?" Duan Luanhong looked at it.

The other party asked, "What a mouth you have..." Duan Luanhong was furious.

"This..." Guo Yuquan came back to his senses when he heard his senior brother's words.

Yes, I did come here to repair my car, but I didn't say it was free. Although the car is still within the three-warranty period, the manufacturer can only be held responsible for quality problems caused by the engine itself. If it is caused by improper use by the user, then I'm sorry.

, all accessories replaced during the maintenance process must be provided by the user.

Now that the situation is not clear, I am boasting about Haikou. I will ask users to pay for it later. Can I go back on my word?

"Brother, what should I do?"

"Cool!" Duan Luanhong ignored his junior brother, walked to the car with a set of opening tools, opened the left and right covers of the engine hood behind the loader, and looked at the engine, "Master, start it and take a look.

"

You are from the manufacturer, you asked me to start it, it was not me who had the problem.

"Okay!" The driver heard Duan Luanhong's words and agreed without saying a word. As soon as he turned the key, there was a sound of metal tapping at the engine timing gear.

Here is the sound of the starter's main gear and flywheel being overloaded.

Duan Luanhong stared at the fan blades. The fan blades only vibrated once, but could not rotate.

"Not good!" Duan Luanhong was shocked when he saw that the fan blades were not moving.

"Stop!" Duan Luanhong shouted to the driver.

Guo Yuquan, who was standing behind Duan Luanhong, heard his senior brother shout loudly and asked in a low voice: "Brother, is the engine locked?"

Duan Luanhong saw many drivers gathered in a circle at the scene. Instead of answering his junior brother's words, Duan Luanhong pulled out the oil dipstick.

"This?" Duan Luanhong was stunned when he looked at the engine oil level. He saw that the engine oil was light white.

The oil level was too high, exceeding the highest mark. Duan Luanhong looked at the entrance of the oil dipstick and saw a lot of oil overflowing.

"Is this an increase in engine oil?" Duan Luanhong pondered. He squeezed it with his hands and found it was very thin, not like the viscosity of normal engine oil. He took a sniff.

"There is no diesel smell." Duan Luanhong thought to himself.

"Water!" Duan Luanhong thought to himself.

From the current point of view, there must be something wrong inside the engine, causing water to enter the engine oil.

One is the cooling system and the other is the lubrication system. Generally speaking, the two have always been inseparable, but now they are "getting better."

So at what point do the two find interoperability?

There are several points in the engine that may cause mutual energy if they are damaged. One is the oil cooler.

The oil temperature of engines equipped with turbochargers is generally very high, and the oil cooler keeps the oil temperature within the ideal temperature range.

The oil cooler is made of aluminum and is very weak. It has been installed several times before.

But ever since the factory director purchased a batch of brazing equipment, the oil cooler has never failed.

The second one is the two rubber sealing rings on the upper and lower cylinder liner.

The cylinder liner is in direct contact with the coolant, and the coolant is sealed in the middle of the water channel by two sealing rings. If the sealing ring is damaged or deformed, the coolant between the two will flow to the oil pan.

Another one is the cylinder head gasket. If the cylinder head gasket is damaged, causing the hole in the water jacket to communicate with the cylinder, the coolant will directly enter the combustion chamber and then flow to the oil pan below.

But which of the three will cause the crankshaft to fail to rotate?

Duan Luanhong stared at the engine and began to think.
