What the hell is a private enterprise?

Chapter 63 Field Test
Tang Yi is not a professional engine designer, so he can only use crude methods, constantly trying various improved models and then comparing R&D experience.

Finally, after comprehensive comparison, there are three modifications with advantages in performance and R&D:
V-type 6-cylinder naturally aspirated 10L engine: Based on the B2 series, it removes the supercharger and reduces the cylinder displacement by half. It has a maximum horsepower of 265, a displacement of 10 liters, and a weight of 510 kg.

V-type 6-cylinder supercharged 10K engine: Based on the previous model, a supercharger is installed, with a maximum horsepower of 360 and a weight of 631 kg;

V-type 12-cylinder naturally aspirated 24L engine: Based on the B2, the supercharger is removed, the cylinder displacement is reduced, but the V12 structure is maintained. It can output 430 horsepower, has a displacement of 24 liters, and weighs 811 kg.

The minimum 6-cylinder configuration is because the displacement of a single cylinder in the B2 series is too large, and multiple cylinders are needed to ensure smoothness, otherwise it will run even more bumpy than a single-bar diesel engine.

In terms of displacement and power density, the technology of these three engines is outdated.

Especially the exaggerated displacement. With the current world engine level, the displacement can be reduced by at least half while achieving the same horsepower. It’s just that the low-speed torque is not as exaggerated as that of a large displacement.

In general, apart from being durable and powerful, these three engines have a big disadvantage in terms of fuel consumption.

However, Tang Wen only played twice, and then sorted out the data and named them respectively.

As a general rule, naturally aspirated engines are suffixed with L, turbocharged engines are suffixed with T, and supercharged engines are suffixed with K.

再结合盖金的首字母缩写和马力，分别就是：GJ265D10L、GJ360D10K、GJ430D24L。

For GJ265D10L: GJ stands for Gaijin, 265 stands for horsepower, D is the first letter of diesel, 10 stands for displacement, and L indicates the intake method.

After all, the products are to be sold in an open and honest manner, so the model names must also be formalized.

Wu Laoer, who had just arrived in Echeng by train, had just got home when he suddenly received a call from Tang Wen saying that he had changed his mind and could provide a high-horsepower diesel engine to the Sanwang Factory. He immediately rushed over without stopping.

He didn't understand the details of the parameters, but the hundreds of horsepower sounded intimidating, so he immediately contacted the other party.

……

Guigang, Guangxi Province.

"Neither of these two can be turned on. Can you guys figure out how to fix it?"

At the gate of the Sanwang Agricultural Machinery Factory, two battle-damaged diesel engines were tied into the bed of a strange-looking truck. They were obviously dismantled from other strange-looking trucks.

Their owner is the boss of the small logging camp, a thin but strong man in a straw hat.

The technicians at the agricultural machinery factory were already used to this and knew what the problem was at a glance.

"Damn it! I told you guys to shut off the engine and close the valves when you run into a pothole. How could you possibly break something so early in the morning?"

The mechanic cursed as he looked for someone to dismantle the machine. Such a serious fault required disassembly and major repairs, replacing burned and deformed parts, and there might even be cylinder scuffing, which was extremely troublesome to fix.

However, the wood factory owner was not happy:

"The Kubota we used before took three or four years to break down, while yours needs a minor repair every two months and a major repair every six months. It's better to buy a smaller one.

The mountains are filled with muddy puddles and swamps, and any tractor would have to make it through like that."

The old technician did not refute on the surface, but in his heart he was complaining:
You take good care of imported tractors and are reluctant to overload them, but you just keep making as many domestic machines as you can. How can this be the same?
However, it is also true that imported products are of better quality, both in terms of parts quality and assembly process.

At present, China has not yet joined the World Trade Organization (WTO), and ISO standards, 5S, 2S and other regulations that are now infamous have not yet been introduced into the country. The quality of workers and workshop environment in large and small factories are very poor.

In a workshop full of oil, dirt and iron filings, workers install the cylinder liners with their hands, bumping and bruising each other. Can the quality be the same as that of the dust-free workshop using special fixtures and semi-automatic assembly?

In 86, a foreigner named Grisch was in charge of the Echeng Diesel Engine Factory. For two years, he did nothing else but focus on management and the product quality improved steadily. However, when he left, the quality declined sharply.

For domestic products to become strong, we have to wait until after the new century when a large number of educated people enter the factories and control the quality of the production lines according to the 2S regulations.

Now... there are so many problems, there's nothing we can do, just fix it. The technician turned around and was about to send the two broken machines into the workshop, but the lumber mill owner stopped him and asked:

"Do you have any refurbished ones? I'd like to buy two to use first."

Refurbishing diesel engines is also a common operation. Anyway, the old and new ones are the same, and there is not much difference for high-intensity use, and it can save a lot.

"Of course, look for that guy over there."

The sawmill owner followed the directions and found a small warehouse where refurbished diesel engines of various qualities were piled up in the semi-open air.

However, what caught his attention was a dismantled diesel engine placed on the open space, with a number of people gathered around it.

He leaned over to take a look, and immediately asked in confusion:
"This machine looks new, why did you take it apart?"

Chen Xiaojie, who was explaining something to several shareholders, looked up and immediately recognized the nearby small business owner. He explained:
"This is a new machine we bought from another company. It's similar to the Yuchai 25, but the workmanship is much better."

The reason why Sanwang Agricultural Machinery decided to buy 50 units first was because they found that Gaijin's machine technology was very stable and the two prototypes were almost identical.

The exterior details are well handled, and there is nothing new inside, but even with the naked eye, you can see that the quality and tolerances of various parts are very well controlled, and are not inferior to imported quality at all.

With precise assembly that fits every corner, the possibility of damage caused by external liquid ingress and vibration is much smaller.

An experienced craftsman in the factory disassembled the entire machine, and his first reaction was that it would be impossible to restore the original quality by putting it back together by himself.

Compared with the loose and even incompatible parts of Yuchai 25, the craftsmanship of Gaijin 25 is simply refreshing.

The lumber mill owner didn't understand much and just asked:
"Is this new diesel engine of better quality?"

"Of course it is. Look, even the anti-rust paint is more evenly distributed than before."

Chen Xiaojie praised the diesel engine because of the PY transaction with Wu Long, and also to enhance the reputation of his brother-in-law.

"How much is a new one? I need one urgently, so I'll get one and try it out."

"This……"

With only one prototype left, Chen Xiaojie hesitated, but a female shareholder suddenly said:
"Sure, that's a good time to put it to the test. Manager Chen, what can you tell just by looking at the surface?"

This female shareholder is one of the rivals of Chen Xiaojie's brother-in-law. Unlike Chen Xiaojie, she strongly disagrees with changing suppliers.

Yuchai is a large local enterprise and its prices are not expensive. Why should it buy products from a small factory of unknown origin?

Domestic products are all of the same quality, what's the difference?
Of course, the most important thing is that she received rebates from Yuchai, so of course she had to speak for the other party.

The road conditions in the red soil of the mountains are so bad that any machine will break down when going there.

"Okay, it's the same price as before."

Chen Xiaojie couldn't refuse, but he was also a little worried about the risk of breakdown under harsh working conditions.

The owner of the sawmill didn't care. According to the local rules, the products come with a three-month warranty, so he might as well try the new product.

At this moment, Chen Xiaojie's pager started beeping.

I looked at the number and it was Wu Long.
