Chapter 31 Using Cadillac as a Teaching Tool
“Master, you are so awesome!”
Seeing Smith walking away, Chen Chenxing’s eyes finally lit up and he was about to jump with excitement.
It’s an exaggeration to earn $1,000 for one car repair!
Even according to the official exchange rate, one dollar can be exchanged for more than one yuan and fifty cents.
It is equivalent to Jiang Hui earning two or three years' salary of many people in one day.
Of course, today's situation is quite special. We happened to encounter a new model that no one else dared to try.
It is estimated that such a good opportunity will be difficult to come across in the future.
"Americans are very rich now. They don't earn much money, so they feel sorry for themselves."
Jiang Hui didn't look embarrassed at all.
What's there to be embarrassed about when it comes to making money with technology?
"I have never seen this car on the road before. Will it be difficult to repair?"
After being excited, Chen Chenxing became a little worried.
If this is not repaired well, not only will the $1,000 that was paid into my mouth be lost, but my reputation will also be affected in the future.
“Hey!”
Jiang Hui couldn't help but smile on his face when he thought of the cause of the malfunction that he had initially confirmed.
If this car were his own, he could have it repaired in just five minutes.
But we definitely can’t do this today.
He would never let the car be "repaired" until the sun went down.
“I’ll tell you slowly later, but now I’ll collect the money first.”
Jiang Hui saw that Smith came back quickly and immediately stopped talking to Chen Chenxing about car repairs.
“It’s $500, you can count it yourself!”
“But the car must be repaired, otherwise you won’t be able to bear the consequences!”
Smith gave the five pictures with a dark face The brand new Franklin was handed to Jiang Hui.
Although there is no way for the U.S. dollar to circulate directly, and the official exchange rate is just that, Jiang Hui is very clear about how the value of the U.S. dollar will increase in the black market.
To put it a bit exaggeratedly, when he goes to buy a courtyard house, if he pays part of the house payment in US dollars, the price will probably be cut down a lot.
Especially when you meet people who sell courtyard houses to go to the United States, this effect will be even better.
"We Chinese people are the most trustworthy. If we say we can fix it, we will definitely fix it. I will never leave here until it is fixed!"
Jiang Hui didn't care about Smith's black face.
Just think that today’s car repair fee already includes other people’s feelings.
"I've given you the money, can we start repairing the car shop?"
Although Smith's tone was bad, the "whispering" voice seemed a bit weird.
"That..."
"Smith, you also know that repairing cars is what I do for a living."
"In China, many of our technologies are If it is passed down from son to daughter, it cannot be taught to others easily.”
"The weather is so hot, do you want to take a rest in the office?"
Jiang Hui spoke in a roundabout way, but Smith understood.
This is about walking away by yourself!
Thinking that he had no better choice, Smith turned around and walked away with a dark face without saying a word!
Waiting until Smith disappeared from sight, Jiang Hui began to ask Chen Chenxing to open the tool box and prepare to repair the car. "Morning Star, the engine used in this car is an electronic injection engine that is very rare in China. It does not have the familiar carburetor and distributor."
"It is replaced by an electronic control unit, that is, the EFI system controlled by the ECU."
Jiang Hui first gave Chen Chenxing a general explanation of the Cadillac ElDorado engine.
Although Chen Chenxing will most likely not have the opportunity to repair this car in the future, the structure of the EFI engine is similar.
One method can solve all problems!
Today's maintenance content is too simple. Just dismantle the engine and treat it as on-site teaching.
“For traditional carburetor engines, the carburetor and distributor often have problems, so the structure and working principle of these two parts must be understood clearly.”
"In the era of electronic injection engines, in addition to conventional problems, the probability of failure of the electronic injection system is also relatively high."
"For the engine in front of us, it is actually the wiring harness connector of the injector that is loose or It fell off, causing engine startup failure."
"This engine is a V8 engine with eight cylinders. If the injector harness connector of only one or two cylinders loosens or falls off, this will cause this If the two cylinders cannot inject fuel normally, the engine can often start normally, but there will be obvious jitter. ”
"This is why Smith said that it could still be used normally some time ago, but the jitter was severe."
"But once more cylinders are unable to inject fuel normally, then even after the engine is started, it will It turned off quickly, just like what we just saw.”
Before the formal teaching, Jiang Hui first told the situation of the malfunction.
This would prevent Chen Chenxing from thinking about things and not being able to listen to his lecture seriously.
“Just...just the wiring harness connector of the injector fell off?”
Jiang Hui's answer refreshed Chen Chenxing's understanding.
For such a small glitch, Master actually quoted us US$1,000. Even according to the original quotation, it was still US$500.
This car repair...
It's really too dark...it's so profitable!
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 had hundreds of more evil eyes than he didn't know!
"Yes, it's that simple!"
"But we can't repair it so quickly. We have to pretend it's difficult, spend a whole day repairing it sweat-soaked, and then take the money and leave."
< br>"Just taking this opportunity, I will tell you about the structure of the engine."
After Jiang Hui finished speaking, he picked up the wrench and started to disassemble the parts.
Disassembling the engine is naturally very particular, and it is not just a matter of doing it haphazardly.
Otherwise, you will fix problems with the engines that have no problems by then, which would be ridiculous.
Jiang Hui disassembled a part, explained the function and common faults of the part to Chen Chenxing, and then put it aside in an orderly manner.
After working hard for almost an hour, it was noon and the engine had not been completely disassembled.
This kind of on-site teaching, the master is great and the apprentice is willing to learn, so the efficiency is naturally very high.
Based on the content of "Principles of Internal Combustion Engines" that he had read before, Chen Chenxing felt that his understanding of engines was immediately apparent.
As a master, I really did not make a mistake!
"You guys come with me to the cafeteria and have lunch before continuing to repair!"
Although Smith no longer had a dark face, he didn't smile either.
While speaking, he glanced at the neatly arranged engine parts on the ground. Although he was a little worried, he also knew that Jiang Hui should have a few brushes.
“The structure of this V8 engine is relatively complex, and it is really not easy to repair. However, we have found the problem and we will definitely fix it this afternoon.”
Jiang Hui and Chen Chenxing looked at each other, immediately put down what they were doing, and followed Smith towards the restaurant.
