Rebirth of the 1980s: The Military Industry Empire

Back then, when the Cherokee was introduced, its localization rate was low, and a large number of parts needed to be imported. This was the main reason for the Cherokee's low sales. Not to mention sales, the country wouldn't approve foreign exchange, and the parts couldn't be bought back.

Therefore, since Qin Yang encountered this, he might as well lend a hand. As long as he could produce the engine himself, the Cherokee would be easier to develop.

Wu Liang, who was also present, also realized that importing the latest off-road vehicle from the Americans, and also getting their engine technology, was too important for their side.

"Yes, please give us the engine data, and we will jointly develop it." Wu Liang said excitedly, "The content we originally discussed was joint development, and now we can just jointly develop it. We are very honored."

Marion on the other side shook his head: "No, no, we will not give you the engine data. We don't think you have the strength. Please give us the turbocharger, and we will match it."

The Americans are not stupid. How could they agree to the Orientals matching it? They would never hand over their engine data. At this moment, they seemed to have regained their former arrogance.

Qin Yang smiled: "Since that's the case, then forget it. Anyway, this project doesn't have much to do with our 960 factory. The advanced turbocharger we developed can be used on other engines even if it can't be used on your engines."

If you don't cooperate, there are others. We don't care.

"Actually, I also have a brand-new technology here that can further reduce fuel consumption. However, since you don't have the sincerity to cooperate, I won't take it out."

Still can reduce fuel consumption? Marion asked curiously: "What kind of technology is it?"

"Why should I tell you?" Qin Yang's attitude was already very displeased at this time.

Dr. Wright persuaded from the side: "President Qin, just talk about the technical principle, it won't leak any secrets. I also want to hear it, so tell everyone about it."

"We are good friends, of course I can talk about it. Let's talk about it when we go out."

Marion's face turned red and white for a while. He hesitated for a while, and finally said: "President Qin, please tell me the relevant technology. If I think it's good, I'm willing to give you the engine data, and we will jointly develop it together."

Qin Yang rolled his eyes at the other party before opening his mouth: "Okay, then I'll talk about it here. If you want to further reduce fuel consumption, you need to focus on the combustion efficiency of the engine. We all know that the engine needs different amounts of air to assist combustion at different speeds. However, in the existing engine design, the intake and exhaust mechanisms are fixed and cannot be adjusted according to the speed."

"That's right, that's how it is, President Qin, can you change these?"

"Of course, as long as the engine is improved a bit, so that the engine's valves can be changed as needed, this can greatly reduce fuel consumption. It is normal for fuel consumption to drop by more than two liters per hundred kilometers."

The fuel consumption of cars is constantly decreasing. In the beginning, the fuel consumption of cars was more than 20 liters per hundred kilometers, and slowly reduced to more than ten liters, and later reduced to a few liters. Some advanced pure fuel cars can run within five liters per hundred kilometers, and even less will be three or four liters, which makes people sigh at the progress of automobile technology.

What technologies are there? Turbocharging and small displacement are all later technologies. In the 1990s, the first technology to be applied was variable valve technology.

First solve the problem of the valves, so that it can inhale the appropriate air according to the needs of the engine, so that the combustion is more complete, and naturally can obtain stronger power and more fuel-efficient fuel consumption.

In later generations, motorcycles have not used these technologies, so motorcycles have become more and more fuel-consuming products. This has to be compared with cars of the same displacement. For example, 800CC, the fuel consumption per hundred kilometers has to be more than seven liters, while the same displacement Xiali, five liters is enough.

"Change the valve? How to change it?"

"Specifically, there are two ways, one is called variable valve lift, and the other is called variable valve timing. These need to be achieved by changing the specific mechanical structure, but how to change it specifically, I'm very sorry, I can't say yet."

Saying these is already enough.

Marion on the other side pondered for a while, and then said: "President Qin, we can give you the engine data. I hope you can match the turbocharger for us. If possible, I also hope to study the technology of changing the valves on it. However, I hope our engineers can be present and follow the research together."

"Of course, the patent is ours. If you use it, you will have to pay us a patent fee for every engine equipped with this technology in the future," Qin Yang said.

This is a wonderful era, being a patent troll can make money lying down!

These technologies were only developed and matured in the 1990s and were installed on various vehicles. In the 1980s, countless engineers were still working hard on research, but Qin Yang already knew what the research results would be.

There are only a few technologies installed globally, among which Toyota's VVT technology and Honda's VTEC technology are the most famous. The latter is more advanced and the technology is also the most complicated, using different camshafts to change the valve lift, while the former is much simpler. However, variable valve lift only works at high speeds. Ordinary people can't bear to step on the accelerator when driving, and they can't experience the benefits of this technology at all.

The East uses DVVT in large quantities, using this system for both intake and exhaust.

Some say that the islanders used these technologies in order to pursue the performance of naturally aspirated engines. In fact, turbocharged engines also need them, and the performance will be stronger after using them.

As for the structure, it is not difficult. The difficulty is the person who came up with it in the first place. Once they come up with it, it is easy for others to imitate.

What's the harm to you? You are purely tripping up the islanders, but the Americans like it!

The Americans present all showed smiles.
