Chapter 97

The power of the current engine system of the Changjiang 750 is 24 horsepower, but the redundancy strength of each component is very high, so even if it is modified to 40 horsepower, there is no need to worry about the strength of other parts being insufficient.

In fact, the potential of the horizontally opposed twin-cylinder engine on the Changjiang 750 is very high. Although the maximum continuous power of this engine is only 20 horsepower (15 kW), and the maximum limit power is only 24 horsepower, many people, upon hearing these figures, would instinctively think that this engine is not impressive. They might think that the BMW G/S, which also uses a horizontally opposed twin-cylinder engine and has a displacement difference of only 50 cc, has a maximum power of over 45 horsepower. Moreover, the BMW G/S uses a relatively less efficient air-cooling system, yet it has 24 horsepower? With water cooling, it barely reaches 40 horsepower?

How embarrassing, Chinese technology is indeed not up to par.

This way of thinking is incorrect. Why? Because the engine of the Changjiang 750 has a relatively low RPM. When maintaining a maximum continuous power of 15 kW, its RPM is only 3,300 revolutions per minute. This means that the engine reaches its redline at 3,300 RPM. What is the redline RPM of the BMW G/S engine? 7,800 RPM, which is 2.36 times the RPM of the engine on the Changjiang 750!

Increasing the RPM is the potential of the horizontally opposed twin-cylinder engine on the Changjiang 750! As long as the RPM increases, the power will naturally increase.

Of course, increasing the RPM is not that simple. As the RPM increases, the requirements for the precision and structural strength of the parts will also rise sharply, far beyond what it was before. However, no matter what, this engine has potential, and it is significant and deep. As long as continuous improvements are made, this engine has the potential to become a star engine like the BMW "Boxer."

When Jindler mentioned that he planned to "overclock" the horizontally opposed twin-cylinder engine and add a water-cooling system, the genes of the automotive designer and engineer immediately became active. He was so excited that he didn't even care if it would ruin the classic charm of the Changjiang 750. He said excitedly, "Since you plan to add water cooling and replace the cylinder block, why don't we thoroughly improve and reinforce the engine?"

"Um... Yes!" Jindler's eyes also lit up. "It sounds very interesting..."

Chen Geng added, "And we don't have to worry about BMW's attitude."

"Exactly, that's right!" Jindler's eyes lit up again. Not having to worry about doing useless work or BMW's protests made Jindler extremely excited. He rubbed his hands together and said, "Let's start now..."

For enthusiasts, the Changjiang 750 is best in its original form, ideally taken directly from a sealed storage in a war reserve warehouse from 20 years ago. However, for technical enthusiasts, whether the Changjiang 750 with water cooling can still be considered the original, emotional Changjiang 750 is not even in their consideration. They care only about performance improvement, performance improvement, and more... performance improvement...

Chen Geng said, "First, we need to strengthen the piston and connecting rod. If we can increase the strength and precision by 20%, we can increase the RPM to... let me calculate, 4,200 RPM should be no problem, but this will require 89-octane gasoline..."

Jindler said, "No problem, your country already has 89-octane gasoline, and in Germany, the gasoline grade has reached 90, so it's completely fine."

Chen Geng said, "In that case, we can increase the compression ratio a bit more. Also, increasing the ignition energy is a good idea. What do you think about using two spark plugs per cylinder? Dual spark plugs for each cylinder..."

Jindler excitedly continued, "Yes, dual spark plugs, why didn't I think of that? This way, the engine can at least produce 50 horsepower. Chen, your idea is great, let's do it! Oh, right, the generator's power output also needs to be increased."

Taking advantage of the heated discussion, Chen Geng casually asked, "Jindler, when this car is sent back to Germany, your father will surely receive a lot of admiration, right?"

He began to implement his plan.

"Of course! Definitely," Jindler immediately looked proud. Finding a replica of a BMW for his father was Jindler's proudest achievement. "The veterans' association my father is in has over 1,000 members, the largest in all of Lower Saxony. Many people want to find a BMW, but do you know? The entire association has only 2! 2!"

He held up two fingers, emphasizing the number "2": "Only 2! These two BMWs are the treasures of the association, and they all belong to the president. My father said the president became the president because of those two BMWs! Remember, I told you before, someone offered 50,000 US dollars to buy one of the BMWs from the president, but he was mercilessly driven away. Hahaha... I'm not surprised at all. The old man treats those two BMWs like his life. He only drives them for major events."

"Chen, do you know how much of a sensation it will cause when my father rides this car to the veterans' association? I bet they will treat my father like a rock star..."

Talking about this, Jindler couldn't stop. He chattered on about how glorious and enviable his father would be with such a Changjiang 750, emphasizing that if he had this car, Old Jindler would be incredibly impressive in every way.

Chen Geng was somewhat "surprised": "Is that so... I didn't expect this car to be so popular. Well, but hearing you say this, I feel like the car is missing something."

"Missing something..." Jindler was taken aback, but after spending time with Chen Geng, he had gone through a cycle of severe doubt, being proven wrong, a bit of doubt, and being proven wrong again. He now instinctively trusted Chen Geng and asked, "What do you think is missing?"

"Accessories," Chen Geng said with a "You're so stupid!" expression, pointing to the clean Changjiang 750 in front of them. "If I'm not mistaken, the BMW has an air-raid light. We can install an air-raid light; we can also install a machine gun mount here; and here, we can place two ammunition boxes; here, we can place a tool box; and here, we can place a shovel, like this..."

As Chen Geng spoke, Jindler's eyes grew brighter. He nodded in agreement as Chen Geng pointed to different parts: "Right, right, that's it. I always felt something was missing, something was off. Now I understand, it's indeed missing some accessories. Ha... With these things installed, it looks much better. Those old guys will envy my father to death..."

"Would ordinary military enthusiasts, I mean, general military fans, like such a car?" Chen Geng asked again.

"Hey, brother, are you kidding me?" Jindler exclaimed dramatically. "Do you know how revered BMW is in Germany? You have no idea! BMW holds an irreplaceable place in the hearts of Germans, not just veterans and military enthusiasts, but even ordinary people want to own one. No, not just own one, but have it like an old car, an old friend. If there is a BMW that can perform well and drive on the road, it will become the envy of everyone."

"So, someone would be willing to pay a high price to buy your father's Changjiang 750, right?"

"Isn't that obvious?" Jindler rolled his eyes, indicating "Chen Geng, you're an idiot!": "Many people will definitely want to buy this car from my father, but I'm sure he won't sell it, even if he has to sell his house. I can swear to you, by God!"

Chen Geng nodded and asked Jindler again, "If one of your father's friends asks him to buy a Changjiang 750, have you thought about what to do?"

"Hmm..." Jindler was taken aback.

He hadn't really thought about it, but after some consideration, Jindler realized it was very normal. When his father's old friends learned that they could obtain a replica of a BMW through some channel, they would go crazy... Hmm?

Jindler is a technical engineer, and he hadn't thought of it, but that doesn't mean he's stupid. On the contrary, he vaguely sensed something, but he was a bit hesitant to believe it: "Chen, what are you really trying to say?"

"I'm saying, do you want to become a millionaire, or even a multimillionaire? Do you want to live in a luxurious villa with gardens in the front and back and a swimming pool in the back? Do you want to drive a luxury car and be respected wherever you go? Do you want to receive the best and most timely medical care when you and your family are sick, without worrying about medical expenses?"

Chen Geng didn't answer immediately but once again piqued Jindler's interest.
