Chapter 738: Two Great Difficulties

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

Park Zhidong, who was walking in front of him, was nervous, and just as he was about to ask Huang Hongxi about the test results, the other party had already rushed to him.

"Miss, minister, the results have come out, and the oil height has risen - 7mm!"

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

For this result, Zhao Guoyang has been prepared for a long time.

Seeing that everyone wanted to speak and stopped, wanting to ask themselves the reason but didn't know where to start, he took the initiative to speak.

"Then, everyone has seen the situation, and this Carlos of your 'Daewoo Automobile' is indeed technically flawed. As for why this is happening? It starts with a cold start of the car. ”

Zhao Guoyang said slowly: "If I guess correctly, your company's Carlos 1.5T direct injection engine, when it starts cold, the engine computer ECU should control the fuel injector for two 'pre-injection', right?"

"Yes, yes, that's true. For this 'pre-injection' technology, our 'Daewoo Motors' and 'Hyundai Group' have competed. 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, your company's innovation is well-intentioned, but it lacks an important step - the specific fuel injection volume is not well controlled!"

Hearing this, Park Zhidong and Huang Hongxi's bodies shook at the same time, as if they had thought 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 the gasoline was not enough, and it was left on the cylinder wall in liquid form, and it was scraped into the oil tank by the piston before it could volatilize......

Zhao Guoyang said this, and the two technical bigwigs, Park Zhidong and Huang Hongxi, already understood the problem.

However, Jin Xiuzhu has not reacted much because she is not a professional.

She asked with some curiosity: "Guoyang, why didn't this happen when I was indoors before?"

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

"As for the indoors, the temperature is still more suitable, even if there are two 'pre-injection', but if the atomization rate is not reduced to a certain extent, it will not have any effect!"

"Ah, I see!" Kim so-joo nodded suddenly.

Bai Rou on the side seemed to think of something, and suddenly asked: "Then according to Guoyang, what you say now, if there is an extreme phenomenon like 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 the start and stop are more frequent. 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?"

Hearing this, Zhao Guoyang gave Bai Rou a thumbs up approvingly and said, "Sister Bai, you are really smart, in a word!"

"That's right, I suspect now that in addition to the first vehicle that found the problem, the cars that followed the South Korean government's problems were all deliberately faulty. The purpose is to completely squeeze your 'Daewoo Motors' out of the sequence of government cars!"

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

She clenched her soft hands into fists indignantly and said, "I knew that this matter was inseparable from the old fox of the 'Zheng family', and it was so!"

Seeing that the eldest lady looked indignant, Zhao Guoyang raised his hand and gently patted her shoulder to show comfort.

When he turned his head to look at Park Zhidong and Huang Hongxi, Zhao Guoyang said with a solemn face: "Although in this matter, the 'Hyundai Group' must have used some shady means, but in the final analysis, your company does have certain technical defects. ”

"In fact, Minister Park, your 'pre-injection' technology patent itself is not a problem, and the fuel injection volume and mixture concentration of the engine are relatively high during cold start, which is more conducive to vehicle ignition. Therefore, it is necessary in principle to carry out two pre-injections. ”

"On the one hand, it allows for a thorough mixture of oil and gas, which is more efficient for combustion, and on the other hand, at some point, it also cools the engine, and the evaporation of the liquid lowers the air temperature in the cylinder. ”

"But your company missed one point, that is, in the cold start state, the control of fuel injection must take into account the climate factors, otherwise it will only lose the whole game......!

Park Zhidong and Huang Hongxi were dumbfounded by Zhao Guoyang's pertinent and fair words, and their faces were full of guilt.

After being silent for a moment, Park Zhidong took the initiative to walk up to Jin Xiuzhu, bowed his head and said, "Miss, what Researcher Zhao said in this matter is completely correct, it is indeed our technical department that made a mistake." I am willing to accept any punishment from the company!"

Huang Hongxi, who was next to him, also hurriedly followed up and said: "Miss, the patent of 'pre-injection' was proposed by me, and it will be punished, and it will also punish me, and it has nothing to do with Minister Park!"

Watching the two of them scramble to accept the guilt, Jin Xiuzhu's heart was soft.

She sighed secretly, turned her head to look at Zhao Guoyang and said, "Guoyang, since you have found out what the problem is. Can you tell me, are the consequences of this hidden danger serious?"

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

"Because it will bring 'moisture' to the oil that should be viscous, and turbocharged engines need oil with high viscosity and 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 oil for this batch of cars, which is one of the correct methods, but it cannot solve the fundamental problem......"

Seeing that Zhao Guoyang seemed to have something to say, Park Zhidong and Huang Hongxi next to him understood something.

Park Zhidong looked at Zhao Guoyang with a sincere face, bowed deeply, and said, "Researcher Zhao, thank you for helping us find out this serious hidden danger. If you can find a way to solve this problem, we at Daewoo Motors will be grateful from top to bottom!"

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

"First of all, the control of fuel injection is the secret of the manufacturer, and it must not be disclosed to outsiders. But if I want to give my opinion, I must know the amount of fuel injected in your 'pre-injection' technology......"

"There's absolutely no problem with this!"

Without waiting for Park Zhidong to speak, Jin Xiuzhu first said, "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 Huaxia!"

Zhao Guoyang sighed, and then said: "We all know that engine fuel injection is controlled by the ECU computer, and this value setting is based on the data of thousands of tests. ”

"Therefore, if it is determined that the fault is caused by improper fuel injection, it seems to be a software numerical calibration, but it also needs to be reset and modified with relatively large data support. ”

"It can 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 we can solve this problem, even if it takes two or three months, we will have to wait. Kim so-joo hurriedly opened her voice.

Park Zhidong and Huang Hongxi saw that this "Researcher Zhao" agreed to help, and their faces showed ecstasy.

Seeing that the crux of the problem was found, everyone breathed a sigh of relief.

Kim so-joo explained a few words to Park Ji-dong and Hwang Hong-hee, and asked them to make a sample of today's test results and keep them for tomorrow's press conference to be announced.

Then, the eldest lady grabbed Zhao Guoyang's arm and said, "Guoyang, go, come with me to meet my father." ”

Zhao Guoyang had a premonition about this, and he was not very strange at the moment, so he just nodded calmly.

……

At half past ten in the evening, the chairman's office on the top floor of the "Daewoo Group" was filled with smoke.

Chairman Kim Woo-jung sat in a wide chair with a tired face, smoking a cigarette without saying a word.

Tomorrow is the time for Daewoo Motors' press conference to all of South Korea, but so far the technical department has not been able to make any substantive discoveries.

In the past two days, he has kept greeting and pleading with officials and bigwigs of the South Korean government, and even did not hesitate to call one of his competitors, Choi Longsheng, the boss of the "Kia Group".

It's just a pity that although Cui Longsheng is very sympathetic to himself and the "Daewoo Group" being blocked by the "Hyundai Group", he doesn't have the courage to stand directly on his side and help out.

After all, the "Hyundai clique" is now too powerful on the side of the South Korean government.

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

In this case, even if Cui Longsheng wanted to help Jin Yuzhong, he didn't dare to act rashly.

Thinking that he had been in South Korea for a lifetime, but in the end he was going to be ruined, Kim Woo-jung was sad.

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

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

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

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