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

Park Ji-dong, who was walking in front of him, felt nervous. As soon as he was about to ask about Huang Hongxi's test results, the other party rushed to him.

"Miss, Minister, it turned out that the oil height has risen-7mm!"

"What! Is it really wrong?" Park Ji-dong exclaimed and turned to look at Zhao Guoyang, with a complex look in his eyes.

Zhao Guoyang had already prepared for this result.

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

"Then, everyone has seen the situation. The Carlos from your Daewoo Automobile does have technical flaws. As for why this happens? This matter 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 should control the fuel injection nozzle to perform twice 'pre-injection' when it is cold-started, right?"

"Yes, yes, that's true. For this 'pre-injection' technology, our 'Daewoo Auto' has also competed with 'Hyundai Group'. In the end, we took the lead and obtained this patent..." Huang Hongxi nodded repeatedly.

Zhao Guoyang nodded to Minister Huang, and then spoke: "Well, your company's innovation is a good idea, but it lacks an important step - the specific fuel injection volume is not well controlled!"

Hearing this, Park Ji-dong and Huang Hongxi shook their bodies at the same time, as if they had forgotten something.

Ignoring the shock of the two, Zhao Guoyang continued: "Because the 'pre-injection' did not control the injection volume well, the atomization rate of the gasoline was insufficient, and it remained on the cylinder wall in liquid form. Before it could evaporate, it was scraped into the oil tank by the piston..."

When Zhao Guoyang said this, two technical bosses Park Ji-dong and Huang Hongxi already understood the problem.

However, Kim Soo-joo hasn't reacted much because she is not a professional.

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

Zhao Guoyang smiled and explained: "The reason is very simple. The outdoor temperature in Seoul has been too low recently, and the atomization rate of gasoline will also decrease accordingly. In addition, if the start and stop are too frequent, this phenomenon will be aggravated."

"As for indoor use, the temperature is quite suitable. Even if there are two 'pre-fuel injections', the atomization rate will not be reduced to a certain level, it will not have any impact!"

"Ah, so that's how it is!" Jin Xiuzhu nodded suddenly.

Bai Rou, who was standing beside her, seemed to have thought of something, and suddenly asked: "So according to Guoyang, if there is an extreme phenomenon such as increasing engine oil, at least two points must be satisfied."

"The first is that the temperature is low enough, and the second is that the start and stop are relatively frequent. So can I assert that someone deliberately met both extreme conditions in the two cars that had problems in the South Korean government?"

After hearing this, Zhao Guoyang praised Bai Rou and said with thumbs up: "Sister Bai, you are so smart, hit the nail on the head!"

"Yes, I suspect now that except for the first vehicle that found the problem, the cars that had problems in the South Korean government were deliberately looking for trouble. The purpose is to completely run you 'Daewoo Auto' out of the government's car sequence!"

Hearing this, Kim Soo-joo could no longer hold back.

She clenched her tender fists in anger and said, "I knew this was unrelated to the old fox of the 'Zheng family', and it was true!"

Seeing the young lady's indignation look, Zhao Guoyang raised his hand and patted her shoulder gently to show comfort.

When he turned to look at Park Ji-dong and Huang Hongxi, Zhao Guoyang said with a solemn look: "Although the 'Modern Group' has definitely used some shameful means in this matter, in the final analysis, your company does have certain technical flaws."

"In fact, Minister Park, your technical patent for 'pre-injection' is no problem. The engine injects fuel and the mixture concentration are relatively high during cold start, which is more conducive to vehicle ignition. Therefore, it is necessary to perform two pre-injections in principle."

"On the one hand, it can allow the oil and gas to be fully mixed, which is more conducive to combustion efficiency; on the other hand, at some point, it can also cool the engine, and the volatility of the liquid will reduce the temperature in the cylinder."

"But your company missed a little bit, that is, when the fuel injection volume is controlled in cold start state, climate factors must be taken into account, otherwise it will only lose all the money! So although the starting point of your company's patent is good, there are still low-level mistakes that should not have been made..."

Park Ji-dong and Huang Hongxi were speechless by Zhao Guoyang's pertinent and fair words, and their faces were filled with guilt.

After a moment of silence, Park Ji-dong took the initiative to walk to Kim Soo-joo, bowed and said, "Miss, what Researcher Zhao said in this matter is completely correct. It is indeed a mistake in our technical department. I am willing to accept any punishment from the company!"

Huang Hongxi next to him also hurriedly followed: "Miss, I proposed the patent of 'pre-injection'. I would punish me, and it is also punished. It has nothing to do with Minister Park!"

Seeing the two rushing to take the blame, Jin Xiuzhu felt soft.

She sighed secretly, turned to look at Zhao Guoyang and said, "Guoyang, since you have found the problem, can you tell me, are the consequences of this hidden danger serious?"

Zhao Guoyang understood what Jin Xiuzhu wanted to ask, so he shook his head gently and said, "The harm of fuel dilution should not be said to be the harm of engine oil dilution, but it is still very large."

"Because it will bring 'moisture' to the oil that should be viscous, while turbocharged engines need oil with high viscosity and thicker oil film to resist friction and reduce wear. This is a negative effect and may even wear the engine."

"So I personally think that the temporary countermeasure that can be taken is to replace the 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, Park Ji-dong and Huang Hongxi next to him understood something.

Park Ji-dong looked at Zhao Guoyang with a sincere face and bowed deeply: "Researcher Zhao, thank you for helping us find this serious hidden danger. If you can have a way to solve this problem, our Daewoo Automobile will be grateful from top to bottom!"

After hearing this, Zhao Guoyang smiled bitterly and said, "There are two major difficulties in completely solving this problem."

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

"This is absolutely no problem!"

Before Park Ji-dong could speak, Kim Soo-joo said first, "Guoyang, you are the most important partner of our 'Daewoo Group'. If you don't trust you, I can't let you travel all the way from China!"

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

"So, if it is determined that it is a fault caused by improper fuel injection, it looks like a software numerical calibration, but it also requires relatively large data support to reset and modify."

"It may take longer to solve this problem. So I can only guarantee that I will do my best to help you reset this number in the shortest time..."

"No problem, absolutely no problem! As long as this problem can be solved, we have to wait for two or three months." Jin Xiuzhu said hurriedly.

When Park Ji-dong and Huang Hongxi saw that "Researcher Zhao" agreed to help, their faces showed ecstasy.

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

Kim Soo-joo, Park Ji-dong and Huang Hong-hee explained a few words, asking them to make today's test results into a sample and keep them for tomorrow's press conference to be announced.

Then, the young lady took Zhao Guoyang's arm and said, "Guoyang, go with me and meet my father."

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

...

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

Chairman Jin Woo-joong was sitting on the wide chair with a tired face, smoking a cigarette without saying a word.

Tomorrow is the time for the "Daewoo Auto" press conference for all South Korea, but the technical department has not yet made any substantial discoveries.

In the past two days, I have been greeting and begging the officials and bosses of the South Korean government, and even calling Choi Longsen, one of the competitors, one of the "Kia Group".

It’s just a pity that although Cui Longsheng sympathized with himself and the “Daewoo Group” for being blocked by the “Modern Group”, he didn’t have the courage to stand on his side and help him.

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

Even the head of the South Korean government seems to have close ties with the "Modern Group".

In this case, even if Cui Longsheng wanted to help Jin Yu get a shot, he would not dare to act rashly.

Thinking of the fact that he was in South Korea for a lifetime but was eventually ruined, Jin Woo-jung felt sad.

For Jin Woo-jung, the defeat is now decided, and the only thing he wants to do now is to send his precious daughter Kim Soo-joo abroad as soon as possible, and ensure that she does not get affected as much as possible.

But thinking of his daughter's always strong temperament, Jin Woo-jung was a little depressed and didn't know how to persuade Kim Soo-joo.

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