King of Industry

When Zhao Guoyang and his party returned to the laboratory, the test results had already come out.

Pu Zhidong, who was walking in front of him, felt tense. Just as he was about to ask Huang Hongxi about the test results, the other party rushed in front of him.

Miss, Minister, the results have come out, the engine oil height has risen - 7mm!

What! Did you really find out what's wrong? Pu Zhidong exclaimed, and when he turned his head to look at Zhao Guoyang, there was a complex look in his eyes.

Zhao Guoyang had already prepared for this result.

Seeing that everyone hesitated to speak, and wanted to ask himself why but didn't know where to start, he took the initiative to speak up.

Well, everyone has seen the situation. The Carlos of your Daewoo Motors does have technical defects. As for why this happened? It starts with the cold start of the car.

Zhao Guoyang said slowly: If I'm not wrong, your company's Carlos 1.5T direct injection engine, when starting cold, the engine computer ECU should control the injector to perform two 'pre-injection' Bar?

That's right, that's true. For this 'pre-injection' technology, we 'Daewoo Motors' competed with 'Hyundai Group'. In the end, we took the lead and got this patent... Huang Hongxi nodded repeatedly.

Zhao Guoyang nodded to Minister Huang, and then said: Well, this innovation of your company has good intentions, but it lacks an important step - the specific fuel injection volume is not well controlled!

Hearing this, Pu Zhidong and Huang Hongxi shook their bodies at the same time, as if thinking of something they had forgotten.

Ignoring the shock of the two, Zhao Guoyang continued: Because the 'pre-injection' did not control the amount of fuel injection, the atomization rate of gasoline was not enough, and it remained on the cylinder wall in liquid form, and was scraped by the piston before it evaporated. Into the oil tank...

When Zhao Guoyang said this, the two technical leaders, Pu Zhidong and Huang Hongxi, already understood the problem.

But because Jin Xiuzhu is not a professional, she hasn't reacted yet.

She asked curiously: Guoyang, why didn't this happen when we were indoors before?

Zhao Guoyang smiled and explained: The reason is very simple, the recent outdoor temperature in Seoul is too low, the atomization rate of gasoline will also decrease, and if the start and stop are too frequent, this phenomenon will be exacerbated.

As for the interior, the temperature is quite suitable. Even if there are two 'pre-injections', if the atomization rate does not decrease to a certain level, it will not have any effect!

Ah, so that's the case! Jin Xiuzhu nodded suddenly.

Bai Rou on the side seemed to have thought of something, and suddenly asked: Then according to what you are saying now, Guoyang, if there is to be such an extreme phenomenon as an increase in engine oil, at least two points must be met.

The first is that the temperature is low enough, and the second is that it starts and stops more frequently. So can I assert that the two cars that the South Korean government had problems with were deliberately met by someone who met these two extreme conditions?

After hearing this, Zhao Guoyang gave Bai Rou a thumbs-up approvingly and said, Sister Bai, you are really smart, you hit the nail on the head!

That's right, I suspect right now that, except for the first vehicle that was found to have problems, the South Korean government's cars that had problems later were all deliberately finding fault. The purpose is to completely run your 'Daewoo Motors' out of government vehicles. In the sequence!

Hearing this, Jin Xiuzhu couldn't hold back anymore.

Angrily, she clenched her catkins into fists and said, I knew that this matter has something to do with that old fox from the 'Zheng family', and it really is!

Seeing the righteous indignation of this eldest lady, Zhao Guoyang raised his hand and patted her on the shoulder lightly to express his comfort.

When turning his head to look at Pu Zhidong and Huang Hongxi, Zhao Guoyang said with a serious face: Although the 'Hyundai Group' must have used some shady means in this matter, in the final analysis, your company's technical It does have certain flaws.”

Actually, Minister Park, your 'pre-injection' technical patent is not a problem in itself. The fuel injection volume and mixture concentration of the engine are relatively high during cold start, which is more conducive to the ignition of the vehicle. In principle, it is necessary.

On the one hand, it can fully mix the oil and gas, which is more conducive to combustion efficiency; on the other hand, at certain times, it can also cool down the engine, and the volatilization of the liquid will reduce the temperature in the cylinder.

However, your company missed one point, that is, in the cold start state, the control of fuel injection volume must take into account climate factors, otherwise it will only lose everything! So your company's starting point for this patent is good, but There are still low-level mistakes that shouldn't be made...

Pu Zhidong and Huang Hongxi were rendered speechless by Zhao Guoyang's pertinent and fair words, with guilty expressions on their faces.

After a moment of silence, Park Zhidong took the initiative to walk in front of Jin Xiuzhu, bowed his head and said, Miss, what Researcher Zhao said about this matter is completely correct. It is true that our technical department made a mistake. I am willing to accept any punishment from the company!

Huang Hongxi, who was next to him, quickly followed up and said, Miss, I proposed the 'pre-injection' patent, and if you want to be punished, you are also punishing me. It has nothing to do with Minister Park!

Seeing the two scrambling to confess the crime, Jin Xiuzhu's heart softened.

She sighed secretly, turned her head to look at Zhao Guoyang and said, Guoyang, since you have found out the problem. Then can you tell me, is the consequence of this hidden danger serious?

Zhao Guoyang understood what Jin Xiuzhu wanted to ask, he shook his head lightly and said, The danger of fuel dilution should not be said to be the danger of engine oil dilution, it is still very big.

Because it will bring 'moisture' to the oil that should be thicker, and turbocharged engines need oil with a higher viscosity and a thicker oil film to resist friction and reduce wear, which has a negative effect, and may even Wear out the engine.

So I personally think that the temporary countermeasure that can be taken is to change the engine oil for this batch of cars. This is one of the correct methods, but it cannot solve the fundamental problem...

Seeing that Zhao Guoyang seemed to have something in his words, Pu Zhidong and Huang Hongxi next to him understood what was going on.

Pu Zhidong looked at Zhao Guoyang sincerely, bowed deeply and said, Researcher Zhao, thank you for helping us find out this serious hidden danger. If you can solve this problem, our 'Daewoo Motors' from top to bottom, All will be grateful!

After hearing this, Zhao Guoyang said with a wry smile: If you want to solve this problem completely, there are two major difficulties.

First of all, the control of fuel injection quantity is a secret of the manufacturer, and it must not be exposed to outsiders. But if I want to give an opinion, I must know the fuel injection quantity of your 'pre-injection' technology...

This is absolutely no problem!

Before Pu Zhidong could open his mouth, Jin Xiuzhu said first, Guoyang, you are the most important partner of our 'Daewoo Group'. If I don't trust you, I can't let you come all the way from China!

Zhao Guoyang let out a huh and continued: We all know that the engine fuel injection is controlled by the ECU computer. This value setting is based on the data of thousands of tests.

Therefore, if it is determined that the failure is caused by improper fuel injection, it seems to be a software numerical calibration, but it also requires relatively large data support to reset and modify.

It may take a long time to solve this problem. So I can only promise that I will do my best to help you reset this number in the shortest possible time...

No problem, absolutely no problem! As long as this problem can be solved, even if it takes two or three months, we will have to wait. Jin Xiuzhu said hastily.

Pu Zhidong and Huang Hongxi were ecstatic when they saw that Researcher Zhao agreed to help.

Seeing that the crux of the problem had been found out, everyone heaved a sigh of relief.

Jin Xiuzhu, Park Zhidong, and Huang Hongxi explained a few words, asking them to make a sample of today's test results and save it for announcement at the press conference tomorrow.

Afterwards, the eldest lady took Zhao Guoyang's arm and said, Guoyang, let's go, follow me to meet my father.

Zhao Guoyang had a premonition about this, so he was not surprised at the moment, but nodded calmly.

...

At 10:30 in the evening, the chairman's office on the top floor of the Daewoo Group was filled with smoke.

Chairman Jin Yuzhong was sitting on a wide chair with a tired face, smoking a cigarette without saying a word.

Tomorrow is the time for Daewoo Motors to hold a press conference for all of South Korea, but the technical department still hasn't made any substantive discoveries.

In the past two days, I have been greeting and pleading with South Korean government officials and bosses, and even called one of my competitors, Cui Yongsheng, the boss of Kia Group.

It's just a pity that although Cui Longsheng sympathized with himself and the Daewoo Group when they were blocked by the Hyundai Group, he didn't have the guts to stand directly on his side and help stand up.

After all, the Hyundai Group is too powerful in the South Korean government now.

Even the head of the South Korean government seems to be inextricably linked with the Hyundai Group.

Under such circumstances, even if Cui Yongsheng wanted to help Jin Yuzhong, he would not dare to act rashly.

Thinking of his glorious life in South Korea, but in the end he would end up in ruins, Jin Yuzhong felt sad for a while.

For Jin Yuzhong, the defeat is now decided. The only thing he wants to do now is to send his precious daughter Jin Xiuzhu abroad as soon as possible to ensure that she will not be affected as much as possible.

But thinking of his daughter's always strong temper, Jin Yuzhong felt a little depressed, and didn't know how to persuade Jin Xiuzhu.

The knock on the door interrupted Jin Yuzhong's thoughts.

He tidied up his messy hairstyle, coughed and said, Come in!
