Great Power Industry: You're a private company building an aircraft carrier?

Qin Chuan smiled and said, "That's right, you're right. But as the best engineer, you should be able to think of a solution, right?"

Hans nodded: "That's right. The best way to make the power available in the low-speed range is to add a small turbocharger. However, this would greatly increase the complexity of the system and raise the failure rate... By the way, you also have a hybrid system. Is it to compensate for the power delay in the low-speed range?"

“That’s right, all of these methods work, but… they all increase the complexity of the entire power system. In fact, there are simpler ways to solve the problem.”

Hans's eyes lit up: "What method?"

"Ahem, well, Mr. Hans, as you should know, if we continue, it will involve the most professional secrets... However, since you are a world-class engine master, we can secretly reveal to you that we plan to use a variable geometry turbine."

This technology, of course, is also the product of the ultimate development of turbocharged engines in later generations!

Small turbochargers have low latency, but limited power gains. Large turbochargers are powerful, but the power delivery is delayed, resulting in a lot of complaints about jerking: when driving in the city, if you press the accelerator too lightly, the car won't move, and if you press it too hard, the car will lurch forward!

How to deal with it?

Of course, it's about combining the two turbines, one large and one small, together!

"Our turbine has a baffle around its exterior. When the engine speed is low, the baffle is closed, and it becomes a small inertia turbine. When the speed increases, the baffle is blown open, and it becomes a large inertia turbine. In this way, it only takes about a thousand revolutions to blow the turbine up, which solves the lag problem and also results in a high maximum power..."

Hans's eyes widened.

Like the BSG, the principle is very simple, but figuring it out is not easy!

"President Qin, you're simply a genius!"

"What genius? This thing has only just been patented, and we don't even know if it's valid yet. After all, it's still just a PowerPoint presentation!" Kim Do-woo thought to himself.

"It's so-so," Qin Chuan said. "Our engine still needs a lot of advanced technology to achieve the goal of high power output from a small displacement."

Hans's eyes lit up: "What other techniques are there?"

"For example, a single cylinder with four valves, variable valve timing, and... cough cough cough, sorry, I can't say anymore, or I'll give away secrets. By the way, is there anything I can help you with here?"

"I'm here..."

What am I here for? Hans suddenly realized that he had forgotten why he came. His eyes were fixed on the engine, his face flickering with light and shadow.

With increasingly stringent environmental regulations, large-displacement engines will become a thing of the past. Within Mercedes-Benz, everyone knows that the V12 will eventually be phased out due to its failure to meet emission standards, and even the V8 will only exist in small numbers. In the future, no matter what kind of car it is, the main displacement will probably stop at 2.0T.

This Laiyang Group is practically prescient! They're developing a revolutionary 2.0T engine that, if it can output 300 horsepower, will even replace the V8 engine!

Currently, Mercedes-Benz has no such plans. After all, any established company has a strong conservative force within it.

Now... the only company that can develop an advanced 2.0T engine is Laiyang Group!

Developing an advanced engine is very difficult, requiring highly advanced materials, processes, and designs. Laiyang Group happens to have these foundations!

Laiyang Group has steel plants and smelting facilities for various advanced alloy materials. They can solve material matching problems internally. In terms of processing technology, they also have advanced CNC machine tools. Moreover, they also have an aircraft engine manufacturing plant and can produce turbochargers themselves!

If there's one thing lacking here, it's design capability. If this engine master himself were to come here...

Thinking of this, Hans took a deep breath: "President Qin, are you short-staffed here?"

Everyone was stunned.

Last time Volkswagen came, they bought the technology; this time Mercedes came, and they just kept the people?

Qin Chuan was also somewhat surprised. He was still thinking about how to keep the other party in suspense, but he didn't expect that the other party would already be thinking about changing jobs!

"Mr. Hans, if you join our engine project, we can hire you as the chief engine engineer!"

"Mr. Qin, I'd like to hear first what other advanced technologies this engine uses..."

“Alright! We’re not worried about leaks anymore, since you’re going to stay and work anyway!” Qin Chuan said, “In the fuel injection system, we’ll use a combination of direct injection and manifold injection.”

Never seen a pig run, but never eaten pork? Tell me about all those advanced technologies from later generations!

Early gasoline engines used carburetors, which injected fuel into the intake manifold and then into the engine through the open intake valve. This is called manifold injection.

The fuel injectors in a diesel engine inject fuel directly into the cylinder; this is called direct injection.

Compared to the two, direct injection technology is more advanced. Therefore, many gasoline engines in later generations also used this injection method. After all, with a high compression ratio, directly drawing in the air-fuel mixture can easily cause detonation during the compression stroke.

However, direct injection cylinders are prone to leaks, a fact that many people have experienced while exercising.

In a later Toyota vehicle, the engine oil level increased because during cold starts in winter, the gasoline injected directly into the cylinders didn't burn completely and slid down the cylinder walls into the oil pan, causing the oil to become too high. The solution was simple: change the oil dipstick. If you can't fix the engine, you can at least change the dipstick.

At the same time, without the flushing effect of manifold injection, the intake valve pushrods are also prone to carbon buildup. Direct injection engines have a much higher rate of carbon buildup than manifold injection engines precisely because of this drawback.

Therefore, the most advanced engine combines the two!

Use port injection when the engine is cold, and switch to direct injection after the engine is warm!

If we're going to develop turbocharged engines, we have to do it to the best of our ability. We absolutely cannot ruin our reputation within a few years!

Qin Chuan explained everything very clearly, and Hans listened with nodding repeatedly: "That's right, that's right, this design is more reasonable!"

Huang Wenlan nodded repeatedly, even though she didn't understand much of what she was saying. But it sounded very impressive. She used to think that private car manufacturers should be controlled, but now she realized that private car manufacturers are more dynamic and, more importantly, can bring more political achievements!

If the German engineers can be retained this time, it will be a huge step forward for the Eastern automobile industry!

"Mr. Hans, our Laiyang Group has always valued talent. With you leading the development of this engine, it will surely become the world's best 2.0T engine and create a miracle! The compensation is 10% higher than that of Mercedes-Benz... However, time is precious. Would you like to start working now?"

"it is good!"

"Then you should sign a ten-year contract first... After all, our engine technology is too advanced, it may take ten years to develop..."

"it is good."
