Rebirth of the Auto Giant

Chapter 577 Abnormal Sound

In a 4S store in Huacheng, a red Wuxing 10 drove into the store's machine repair shop. A man in his thirties, wearing slippers and shorts, got out of the car with a gloomy face.

Master Cheng Yingxun, wearing a one-piece overalls, walked over.

There are four large black characters "Tang Dynasty Automobile Maintenance" printed on the top of the left pocket.

"Excuse me, how can I help you?" Cheng Yingxun stepped forward and asked politely.

"What can you do for me? See for yourself, what evil things you have done!" the car owner scolded, with a sullen face as if he was about to start meditating.

Cheng Yingxun was stunned and said, "What happened?"

"See for yourselves and see what a good thing you have done. In order to sell car parts, you just killed the engine of my car that was less than a year old."

"Although we don't know what's wrong with your car now, as long as it's our responsibility we must take responsibility to the end." Cheng Yingxun said, then took the key from the other party and started the car.

The car made a clanking sound.

"There is something wrong with this abnormal noise." Cheng Yingxun started the car. When the car was at low speed, the abnormal noise would be more obvious, like the sound of metal knocking.

Cheng Yingxun is the fourth generation disciple of Tang Dynasty Power Company Service Department, and studied under Huang Can’s disciple Du Yongzhen.

A graduate with a bachelor's degree in professional automobile maintenance, he applied to Tang Dynasty Power Company with excellent results. The company saw that Cheng Yingxun had strong hands-on ability and a solid professional foundation, so he was sent to the service department and started to learn Wu Xing 10 automobile maintenance with Du Yongzhen.

I have 5 years of work experience and am also a master craftsman.

Drive the car onto the double-arm crane in the maintenance yard.

There is a deep pit on the front of the double-arm crane, which is used for draining engine oil, installing oil and gasoline filters, and inspecting the chassis.

"My car came to you for maintenance a week ago. I didn't expect that the sound of the engine was different from before. At low speed, I found a ding-dong-ding-dong sound, as if there were metal particles knocking in the cylinder, and it was accompanied by

Due to the stalling phenomenon, the speed dropped from 60 kilometers to 30 kilometers. Look, the fault light is on." The car owner came to China and pointed to the fault light on the dashboard.

Thanks to the intelligent service management system developed by Tang Dynasty, whenever there is a problem with the car, the fault light will light up. This is a signal sent back by many sensors.

"First of all, I speak with my conscience. From a professional point of view, your engine must have malfunctioned. We don't know where the problem is at the moment. We need to check it slowly and step by step. If it is our problem, we will definitely solve it.

We will be responsible to the end. If it is not our problem, then again, if you want to repair it here, we will do it according to the market price. Brother, do you think this is true?"

"We are Tang Dynasty, such a big company. We will not do anything that damages the company's image just for a small profit. We deliberately destroy your engine just to overhaul it and earn your spare parts money. If so,

If it were, a company as big as ours wouldn't have been able to survive until now, and would have closed down long ago."

"It's useless to say this, isn't it? What you say is unfounded. Anyway, you must give me a reasonable explanation, otherwise I will call the police." The other party's anger has not subsided, and he will not listen to Cheng Yingxun's words.

"I know you are angry. You will definitely not listen to what I say now. So, let's check first to see where the problem is and then make a plan. What do you think?" Cheng Yingxun looked at the other party and said.

When the other party saw Cheng Yingxun saying in a good voice, he responded with a yes.

"Okay." After Cheng Yingxun said this, he came to the car, opened the front cover, and asked the owner to start the car.

"This sound seems to be coming from the oil pump." Cheng Yingxun said.

"What's wrong?" At this time, Du Yongzhen appeared next to Cheng Yingxun.

Grain certificate

He was resting upstairs just now when he heard his apprentice Fu Boyuan come to report that a user was here to cause trouble.

"Master, listen, this is the car that came here for maintenance last week. Now you hear, it seems that there is an abnormal noise coming from the side of the oil pump, and the speed of the car is very unstable, accompanied by a serious stall phenomenon." Cheng Yingxun said The car owner repeated what he said.

"Well, it's indeed abnormal. Find out who did the maintenance at that time and call him over." Du Yongzhen said.

Cheng Yingxun went back to the service counter. The lady at the counter checked the maintenance records and found that Cui Rongxuan had done the maintenance.

The two came to the car.

"I followed the operation strictly at that time, and the engine oil I added was also special oil. There was no abnormal noise during the test run," Cui Rongxuan said.

Cui Rongxuan, like Cheng Yingxun, is a fourth-generation disciple and studied under Li Shengfeng, a third-generation disciple.

"It's useless to say anything at this time. You will definitely not admit what you have done." No matter what the masters said, the car owner just refused to admit it.

"Master, look!" At this time, Cheng Yingxun opened the engine oil cap and saw some white crystal particles. He wiped some with his hand and handed it to Du Yongzhen.

"Where did this come from?" Du Yongzhen looked at Cui Rongxuan.

"I don't know, I definitely didn't add it." Cui Rongxuan said, then Cui Rongxuan took one and licked it with his tongue, "It's sweet, uncle, this is white sugar." Cui Rongxuan said.

Tang Dynasty Power Service Department has always paid attention to inheritance. This is the cultural tradition of Tang Dynasty Power Service Department. Every apprentice is very particular about where he learned from.

Master Cui Rongxuan is Li Shengfeng, and Li Shengfeng and Du Yongzhen are both third-generation disciples. They arrived in the service department earlier than Li Shengfeng, so they are older than Li Shengfeng in terms of generation, so Cui Rongxuan calls Du Yongzhen his uncle.

"White sugar?" Du Yongzhen has been working in the industry for more than ten years, and this is the first time he has encountered white sugar in an engine.

Du Yongzhen also licked it and found that it was indeed white sugar.

"Quickly, turn off the flame!" Du Yongzhen relied on more than ten years of work experience. As soon as he discovered that it was white sugar, he quickly asked his apprentice Cheng Yingxun to turn off the flame.

"Master, what would happen if sugar was added to this car?" Cheng Yingxun asked habitually.

"You two are majoring in car maintenance. You can tell yourself." Du Yongzhen asked.

The two were undergraduates in automobile maintenance. After thinking for a while, Cheng Yingxun said: "Saccharide is a white crystal composed of three elements: carbon, hydrogen, and oxygen. It is not easily soluble in engine oil. If white sugar is added to the engine, together with the engine oil, Since white sugar is not easily soluble in engine oil, it will cause core precision components such as cylinder liners, piston rings, and oil pumps in the engine to intensify their wear. I think it should be the culprit of engine stalling," Cheng Yingxun explained.

"Well, as expected of a college student, chemistry has not been handed over to the teacher yet, that's true." Du Yongzhen nodded with satisfaction after hearing his apprentice's analysis.

"Drain the engine oil now." Du Yongzhen said.

The car owner was listening to the discussion of the three people. He heard that it made sense but did not say anything. He thought to himself, let me see how you can direct and act on your own.

But now that I heard that the other party was going to drain the engine oil, it was not good to scream because they were trying to destroy the evidence.

"No!" the car owner stopped and said, and took out his phone to call the police immediately. "This is to destroy the evidence. I will call the police right away." The car owner said threateningly.

"Don't worry, we will put it in a bucket and give it to you. We only do this for the safety of the car. Before the sugar dissolves into the oil, please let go of the oil and sugar." Du Yongzhen dared not stop the other party from calling the police.
