The car giant started by marrying the daughter of the king

Chapter 31 Using Cadillac as a Teaching Tool
"Master, you are awesome!"

Seeing Smith walk away, Chen Chenxing's eyes finally lit up and he was so excited that he almost jumped up.

It’s outrageous to make $1000 for repairing a car!
Even according to the official exchange rate, one US dollar can be exchanged for more than 1.5 yuan.

This is equivalent to Jiang Hui earning two or three years' salary for many people in just one day.

Of course, today's situation is quite special because we happened to encounter a new car model that others dare not try.

It will probably be hard to come across such a good opportunity in the future.

"Americans are very rich now, and they would feel a little sorry for themselves if they don't make more money."

Jiang Hui didn't look embarrassed at all.

What's there to be embarrassed about when earning money through skills?

"I've never seen this type of car on the road before. Will it be difficult to repair?"

After the excitement, Chen Chenxing felt a little worried.

If this can't be repaired, not only will the $1000 that I have earned be lost, but my reputation will also be affected.

"hey-hey!"

Jiang Hui couldn't help but smile when he thought of the cause of the failure that he had preliminarily confirmed.

If the car was his, he could fix it in less than five minutes.

But we definitely can’t do that today.

He would never have the car "repaired" until the sun went down.

"I'll tell you slowly later. Now just take the money first."

Jiang Hui saw Smith coming back quickly and immediately stopped talking to Chen Chenxing about car repair.

"500 dollars, count it yourself!"

"But the car must be repaired, otherwise you will not be able to bear the consequences!"

Smith handed five brand new Franklins to Jiang Hui with a gloomy face.

Although the US dollar cannot be circulated directly and the official exchange rate is just that, Jiang Hui is very clear about how the value of the US dollar will increase in the black market in the future.

To put it in an exaggerated way, when he goes to buy a courtyard house, if he pays part of the payment in US dollars, the price can probably be cut by a large margin.

This effect will be even better if you meet someone who is selling his courtyard house to America.

"We Chinese are the most trustworthy people. If we say we can fix it, we will definitely fix it. I will never leave here if we don't fix it!"

Jiang Hui didn't care about Smith's dark face.

Just think of it as today’s car repair bill already including other people’s looks.

"Now that I've given you the money, can we start the car repair shop?"

Although Smith's tone was very bad, that "cooing" voice seemed a bit weird.

"that……"

“Smith, you know that repairing cars is my livelihood.”

"In China, many of our technologies are passed down to sons and not daughters, and cannot be easily passed on to outsiders."

"It's so hot, do you want to go to the office and take a rest?"

Jiang Hui spoke in a roundabout way, but Smith understood him.

This is to walk away by yourself!

Thinking that he had no better choice, Smith turned around and walked away with a dark face without saying a word!
Jiang Hui waited until Smith disappeared from his sight before he asked Chen Xingxing to open the tool box and prepare to repair the car. "Chen Xing, the engine used in this car is a very rare electronic fuel injection engine in China. It does not have the carburetor and distributor that everyone is familiar with."

"It is replaced by an electronic control unit, or ECU, which controls the electronic fuel injection system."

Jiang Hui first gave Chen Chenxing a brief explanation of the engine of the Cadillac El Dorado.

Although Chen Chenxing is unlikely to have the opportunity to repair this car in the future, the structure of electronic fuel injection engines is similar.

One method is applicable to all methods!
Today's maintenance content is too simple, so I just disassemble the engine and use it as an on-site teaching.

"For traditional carbureted engines, problems often occur with the carburettor and distributor, so the structure and working principle of these two parts must be clearly understood."

"In the era of electronic fuel injection engines, in addition to conventional problems, the probability of failure of the electronic fuel injection system is also relatively high."

"For example, in this case, the injector wiring harness connector is loose or detached, which causes the engine to fail to start,"

"This engine is a V8 engine with eight cylinders. If the injector harness connector of only one or two cylinders is loose or detached, resulting in the two cylinders being unable to inject fuel normally, the engine can often still start normally, but there will be more obvious jitters."

"That's why Smith said it was still working fine a while ago, but the vibration was quite severe."

"But once more cylinders are unable to inject fuel normally, the engine will quickly stall even after starting, just like what we just saw."

Before the formal teaching, Jiang Hui first explained the situation of the fault.

This is to prevent Chen Chenxing from being preoccupied with other things and not being able to listen to his lecture seriously.

"Just...just the injector wiring harness connector fell off?"

Jiang Hui's answer refreshed Chen Chenxing's cognition.

For such a minor fault, the master quoted a price of $1000. Even according to the initial quote, it would have been $500.

This car repair...

It’s really too shady… and it makes too much money!

However, he also knew that he should not be petty in front of Jiang Hui in the future, because this master who was younger than him was hundreds of times more cunning than himself!
"Yes, it's that simple!"

"But we can't fix it so quickly. We have to pretend it's very difficult, work hard for a whole day, and then take the money and leave."

"I'd like to take this opportunity to explain the structure of the engine to you."

After Jiang Hui finished speaking, he picked up the wrench and started to disassemble the parts.

Of course, there are some techniques to disassembling an engine, and you can't just do it brute forcely.

Otherwise, even engines without any problems will have problems after you repair them, which would be funny.

Jiang Hui took apart a part and explained to Chen Chenxing the function and common faults of the part, and then put them aside in order.

After working for almost an hour, it was already noon and the engine had not been completely disassembled.

This kind of on-site teaching is very efficient when the master is capable and the apprentice is willing to learn.

Combined with the content of "Principles of Internal Combustion Engine" he had read before, Chen Chenxing felt that his understanding of engines had suddenly reached a high level.

I really didn’t choose the wrong master!

"Come with me to the cafeteria to have lunch and then continue repairing!"

Although Smith no longer had a gloomy face, he didn't smile either.

As he spoke, he glanced at the neatly arranged engine parts on the ground. Although he was a little worried, he also knew that Jiang Hui should be quite capable.

"The structure of this V8 engine is quite complicated, so it's not easy to repair. But we have found the problem, and we will definitely be able to fix it this afternoon."

Jiang Hui and Chen Chenxing looked at each other, immediately put down their work, and followed Smith to the restaurant.
