Geng Shaojie was speechless, but Dr. Li Jun, director of the gasoline engine research office of FAW Automobile Research Institute and chief engineer of FAW Group, heard that Runhua Industrial seemed to provide two v6 engines with different displacements for this car, and Runhua Industrial seemed to be very proud of the reliability and quality of this engine, so he couldn't help it.

With his identity and professional ability, he naturally doesn't have to wait until Chen Geng and Geng Shaojie finish talking. So seeing Geng Shaojie not speaking, Li Jun immediately asked Chen Geng: "Mr. Chen, how are the performance of these two engines? Can you briefly introduce these two engines?"

This is the question that real technicians should ask. Chen Geng nodded as a respect for his peers and said: "These two engines use a single overhead camshaft soHC structure. In order to have better power performance at low speeds, we have equipped both engines with the most advanced variable valve technology in the world today. With our own electronic injection control system, the 2.5 engine can reach a maximum horsepower of 177 horsepower at 6200 rpm, a maximum torque of 220 Nm at 4400 rpm, a maximum torque of 208 horsepower at 6200 rpm, and a maximum torque of 270 Nm at 4400 rpm...

As for this 2.5-liter V6 engine, you can think of it as a model that reduces the emission of cylinder bore by increasing the cylinder liner thickness and reducing the cylinder bore by increasing the cylinder liner thickness. The main components of the two engines except the piston are basically universal."

That's right, this is the product after considering the actual technical situation of Daorunhua Industrial. Chen Geng made fine-tuning of Toyota's 3gr-fe and 5gr-fe, and changed the Toyota's 3gr-fe and 5gr-fe to a single overhead camshaft inlet and exhaust mechanism with a simpler, lower cost and lower technical difficulty. The result is that compared with the 3gr-fe and 5gr-fe that use double overhead camshafts and double vvt-i, the overall performance is only about 90% of the original Toyota.

However, this also brings huge upgrade potential to these two engines. In the future, by replacing the single overhead camshaft with a double overhead camshaft, the single intake variable valve technology will be upgraded to the intake and exhaust variable valve technology, and even the direct and simple and crude upper turbocharger and mechanical supercharge... To be honest, these two engines can be used for at least another 30 years.

"That is to say, if the cylinder liner and piston of the 3.0 engine are replaced, the 2.5 engine will immediately become 3.0?" Dr. Li Jun asked immediately.

"It can also be said," Chen Geng nodded: "But in order to better utilize the performance of this 2.5-liter v6 engine, we have fine-tuned the ignition, compression ratio, intake and exhaust and distribution systems of this engine."

Before Chen Geng finished speaking, Dr. Li Jun suddenly interrupted him and asked, "Mr. Chen, what is the compression ratio of your engine?"

"3.0 is 10.5, 2.5 is 10..."

"You are lying!" Li Jun stood up suddenly and said angrily: "You are lying!"

"Oh?" Chen Geng was not angry, but just raised his eyebrows: "What did I lie?"

"Your engines are absolutely impossible to reach this power level!"

"Why can't our engines reach this fundamental power level?" Chen Geng was so upset by Li Jun's words: "Why can't our engines reach this power level?"

Li Jun became more and more angry: "What? Are you not convinced?"

"What does it mean to accept it?" Chen Geng, who was both angry and funny, was so upset: "Comrade Li Jun, although you are an expert in gasoline engines at FAW Automobile Research Institute and are considered the number one figure in China, you have no evidence and no evidence to accuse me of lying without any silence. What do I admit?"

At this time, Geng Shaojie had to speak. He frowned and said to Li Jun: "Comrade Li Jun, you can't talk nonsense without real evidence..."

You cannot say nonsense without real evidence. This is understood in reverse, that is, if there is real evidence, it is not considered nonsense.

Pointing at Chen Geng, Li Jun said angrily: "Okay, since Mr. Chen doesn't admit it, then I'll tell you my evidence!"

"Okay," Chen Geng changed his position and nodded with a smile: "I'll listen with stern!"

Damn!

In Li Jun's opinion, Chen Geng's indifferent attitude was a serious provocation to his professional ability! He was simply about to be

Chen Geng's shameless posture was so angry that his face turned red: "The ca488-3 2.2-liter inline four-cylinder gasoline engine introduced by FAW from Chrysler Automobile in the United States is one of the most advanced gasoline engines in the world. It also uses a single overhead camshaft structure, and reaches the maximum output power at a speed of 4500 rpm: 87 horsepower, and the maximum torque at 2800 rpm is 157 Nm, and the compression ratio is 8.7..."

Speaking of this, Li Jun could no longer hold it back and slapped the table with a sudden slap, angrily: "Chrysler's ca488-3 engine is one of the most advanced engines in the world today. Its maximum power is only 87 horsepower, its maximum torque is only 157 Nm, its compression ratio is only 8.7, and its maximum speed can only reach 4500 rpm!

But according to Mr. Chen, their 2.5 engine is only 0.3 liters higher than our ca488, but the maximum power can reach 177 horsepower, the maximum torque can reach 220 Nm, and the engine speed can reach 6200 rpm, which is 1800 rpm higher than our ca488!"

Staring at Chen Geng with great anger, Li Jun felt that he was so angry: "With your technical level, you absolutely cannot do it!"

"It's because of this?" Chen Geng was amused by Dr. Li Jun's argument and argument: "Just because the ca488 engine you introduced from Chrysler Automobile in the United States is such data, so you think that our engines cannot be better than Americans in any case. Our engine speed cannot be higher than Americans, the compression ratio cannot be higher than Americans, and the maximum power and maximum torque cannot be higher than Americans?"

"Of course!" Li Junbosch said with confidence: "The Americans' technology is so advanced. Their current technology has been accumulated over hundreds of years since the First Republican Revolution, and even Americans cannot do it. How can you, Runhua Industrial, a company that has been established for less than 10 years?

Looking at Li Jun, Chen Geng didn't say anything. After a while, he sighed and said to Geng Shaojie: "Mr. Geng, do you think so too?"

Geng Shaojie did not say yes or no, but said: "Dr. Li Jun is not only an expert in gasoline engines at our FAW Automobile Research Institute, but also the top technical expert in our country..."

"Understood……"

Chen Geng nodded. Although Geng Shaojie did not admit that he thought Li Jun was right, what is the difference between this and admitting directly?

It's really like this, it's really sad, it's really disappointing, it's really hard to believe that such words were actually said from the mouths of well-known domestic gasoline engine experts. It's really like someone said that some people's braids were cut on their heads, but the braids in their hearts were always there, but...

Good too!

Since that's the case, what else can I be polite?

Looking up, Chen Geng asked: "Dr. Li Jun, according to your point of view, because Americans have accumulated enough in industrial technology and have accumulated enough time, we who are poor and innocent will never surpass Americans, right?"

Li Jun was not stupid. He hesitated for a moment and said, "This... cannot be said too absolute. I admit that in some areas, if you give your strength to do something, you can still surpass the West. However, this situation is not universal, it can only be an individual case. It must be done with the state organizing a general battle and exerting the strength of the country." After a pause, he specifically emphasized: "For example, it is like an atomic bomb or a hydrogen bomb."

Even if Chen Geng said something, who doesn’t know that two bombs and one satellite is the pride of us Chinese? But now I said it in advance, Chen Geng can’t use two bombs and one satellite as an example, right?

Under the obscure expressions of Li Jun and Geng Shaojie, Chen Geng suddenly laughed.

It’s not that the trump card was revealed but pretended to be a smirk, but a smile from the bottom of my heart. It was a bright smile, with deep contempt and sadness towards Li Jun: “I won’t say that the ca488 engine you introduced from Chrysler in the 1980s or the engine technology developed by Chrysler in the 1960s. The performance indicators of ca488 have long been outdated, and you are still taking it as a treasure. I will say one thing: Why do you think that we Runhua Industrial can’t do anything that we can’t do? Over the years, are there few things that we Runhua Industrial have done that seem completely impossible to others? If everything follows the rules, will there be today’s Runhua Industrial?”

Li Jun's face turned red and white, but he said stubbornly: "No matter what you say, I don't believe you can make such an advanced engine..."

"It means that you FAW cannot make such an advanced engine, but it does not mean that we Runhua Industrial cannot do it," interrupted Li Jun, Chen Geng looked at his gaze with disappointment: "I know you won't believe it no matter what I say, so what I want to say is, Comrade Li Jun, we technicians are not verbal, they only rely on their ability to make a living. Do you dare to take the engine testing equipment of your Automobile Research Institute back to our Runhua Industrial with me and personally inspect our engines?"

Li Jun never expected Chen Geng to give such an answer, and for a moment he was a little difficult to judge: Did he pretend to be calm, or did they really make such an engine?

This idea just came out and was denied by him: No, no, no, this is impossible. Even our FAW Auto Research Institute, which has the strongest R&D capabilities in the country, dare not expect to make such an advanced engine. Runhua Industrial is just a company that has been established for less than time. Why can it do all this? They cannot do it!

He must be bluffing!

That's right, it must be like this.
