Chapter 245 Investing in the Old District Diesel Engine Factory

"Mr. Qin, what does Hikoda Shizuo's son have to do with Carl from MAN?" The matter has been finalized. Hikoda Shizuo racked his brains, thinking about how to complete the technical transformation of the factory under the premise of five million. Lin Bin curiously asked Ask Qin Tao secretly.

"His son studied in Germany and went to MAN during his internship. As a result, he and Carl became masters and apprentices." Qin Tao said: "It is absolutely a shame for the son of a machine-building genius to become a master of others! "

No wonder Hikoda Jushio agreed so happily. On the one hand, he had shown his trump card. Anyway, it was just the money, so let’s figure it out! If it doesn't work, replace him. On the other hand, it's also because Qin Tao caught Hikoda Shizuo's weakness and hit the vital point directly.

Five million US dollars is the price that their Bincheng Diesel Engine Factory can accept. They can just grit their teeth and spend the money to upgrade. At this time, Lin Bin is very looking forward to the prospects of their factory after the upgrade.

"Mr. Qin, thank you for your help." Lin Bin looked at Qin Tao and said seriously: "After research by our factory committee, we have decided to hire you as the honorary consultant of our factory. I hope you can accept it."

Honorary Advisor?

Qin Tao glanced at Lin Bin curiously, what do you want to do?

"Please don't misunderstand us. We won't put any burden on you. You don't have to stay here all year round. As long as you come to Bincheng occasionally, you can come to visit us." Lin Bin told Qin Tao: "We know. The salary of an honorary consultant is not enough to break your teeth. This is just a little bit of our thoughts. I heard that you have been looking for a suitable diesel engine factory. Our factory is willing to join forces with Mingzhou Shipbuilding Industry Group. "

Qin Tao smiled helplessly: "You want to provide supporting equipment for our factory. If there is an opportunity in the future, we will cooperate. What is the title of consultant..."

"Mr. Qin, please accept it."

"Okay." Qin Tao agreed. In this way, Qin Tao finally stepped into the circle of marine diesel engines. After entering the circle, it would be easier to find an opportunity to get a certain diesel engine factory under his control.

"It's just that your factory produces low-speed diesel engines and cannot be used on warships. You can try it on cargo ships if you have the opportunity in the future. If the customer decides to accept our domestic main engine, we will help sell it." Qin Tao promised.

Marine diesel engines can be divided into two-stroke and four-stroke according to the working principle. According to the speed of rotation, they can be divided into low, medium and high.

Low-speed diesel engines can turn over a hundred or even dozens of revolutions per minute. There are also slightly higher four-stroke models that can turn to three or four hundred revolutions.

Because the speed is extremely low, there is no need for a reduction gear, and the propeller can be driven directly, eliminating the need for a reducer. Some can even reverse, eliminating the need for reverse gears. And because of the slow speed, its lifespan is very long. Tall, just like a turtle.

Moreover, although it is called a diesel engine, it can not only burn light diesel, but some can even burn heavy oil, which is quite economical, and has become the first choice for many international ocean freighters.

However, there are also disadvantages. This kind of diesel engine is very large and has a high volume-to-power ratio. Therefore, it is not suitable in places where land is at a premium, such as warships.

The new frigate planned by Qin Tao uses four 16PA6V diesel engines from the old factory. These are medium-speed diesel engines. They need to be long-lasting, powerful and compact in size. The speed of this medium-speed diesel engine ranges from 600 to more than 1,000 rpm.

As for the missile boats that have been mass-produced now, they use MTU's high-speed diesel engines, which are small in size and powerful, and can run more than two thousand revolutions per minute. (This is the case with diesel engines. If you want to be like a gasoline engine, it is impossible to turn it on at 10,000 rpm. There are also high-speed diesel engines that can reach 3,000 or 4,000 rpm, which is already very impressive. The classification of this speed is also roughly It’s not that Huadongxiong is unprofessional, it’s just that there are different opinions.)

Although Mingzhou Shipyard now also has large ocean-going cargo ships, without exception, they all use imported main engines. On the one hand, it is the requirements of customers, and on the other hand, domestic diesel engines are not enough.

But after the technical transformation of Bincheng Diesel Engine Plant, their production capacity can be rapidly increased, not only for Bincheng Shipyard, but also for other shipyards. Therefore, Lin Bin hired Qin Tao as a technical consultant. I also want to take advantage of it.

However, domestic diesel engines must always be developed, domestic products must be self-reliant, and the freighters produced in the future must be slowly equipped with a domestic heart.

At this time, Lin Bin was very happy to hear Qin Tao say this.

"Thank you, Mr. Qin! Without you, I'm afraid our factory's technical transformation would not be able to proceed." Lin Bin sighed with emotion: "Complete our transformation with the minimum cost, seek truth from facts, and follow our own path. This is what we The most correct choice!”

"Look at how many color TVs, motorcycles, refrigerators, washing machines, and even automobile production lines have been introduced in our country over the past few years. Each factory has taken the country's money and borrowed money from banks to compete with each other. It all depends on which imported production line is better. However, after the introduction, quite a number of production lines cannot operate, cannot produce, and cannot create value. This is simply..."

"Waste." Qin Tao gave an accurate word.

"That's right, it's a waste!" Lin Bin sighed with emotion.

After the country opened its doors, China introduced a lot of advanced technologies from the West. Some of them began to bear fruit in China, while others were left aside and idle.

In the automotive industry, the imported Santana is a model of success. FAW spent a huge amount of money to introduce an engine production line from abroad, but it was just left there.

In the aviation engine industry, the domestically introduced Spey engine was such a key project at the time, but what about now?

Many things that were introduced at high prices were wasted. Their Bincheng Diesel Engine Factory must not follow this old path. They must take a path that suits them! They must also set an example for other factories.

Moreover, as the country gradually moves closer to a market economy, there will be fewer and fewer projects that rely entirely on state investment and introduction. Most of them need to be carried out independently by enterprises.

"Boss Qin, I heard that the Navy has begun to demonstrate the frigate plan with a displacement of 4,000 tons. It was your suggestion." Lin Bin suddenly changed the subject.

This project cannot be hidden. When Wu Shengli began to demonstrate it in the Navy, the news came out.

Everyone was shocked.

After all, the most advanced 053H2 frigate currently under construction in China has a displacement of only about 2,000 tons. Now, we are actually going to use a 4,000-ton frigate?

The destroyer under construction is only more than 4,000 tons!

Over the years, everyone has been very clear in their hearts that if you take a big step, you will easily get into trouble. This step is really big.

"Yes, we plan to build a new generation of frigates for the navy. The displacement is increased in order to install our most advanced domestic vertical air defense missile system."

If it weren't for Qin Tao's involvement, now they can only replace the Hongqi 61 with the Hongqi 7 and install it on the frigate to form the 053H3 frigate. As a result, Qin Tao took a big step.

"I don't know about other things, but your plan to combine two diesel engines has a lot of technical risks. Those who oppose you are all considering it from this perspective." Lin Bin said.

Qin Tao helped them a lot, so of course they had to provide Qin Tao with some information.

Wu Shengli did not tell Qin Tao about these things. On the one hand, it was still early and nothing had been done yet. On the other hand, Wu Shengli might have to remain silent for the sake of fairness.

However, this technical problem had long been considered by Mingzhou's technicians.

"Then let's use facts to shut them up." Qin Tao said.

"Boss Qin, you can always create miracles. Since you have this advance preparation, I won't say much." Lin Bin said, "The director of the Laoqu Diesel Engine Factory and I were classmates before. He also looks forward to your visit and research at their diesel engine factory and to discuss countermeasures together."

The Laoqu Diesel Engine Factory is still waiting! After all, the plan proposed by Qin Tao requires four diesel engines for one warship. Doubling the number means that their factory will have twice as many orders, so of course they are full of expectations. Moreover, the previous frigates used 18E390A diesel engines, which were not produced by their factory. Now choosing their diesel engines means that big business is coming.

However, the problem of using two diesel engines to drive one propeller is really in front of us.

"I won't go to the Laoqu Diesel Engine Factory. You and their factory director are classmates, so please tell him to send us the relevant data of the diesel engine so that we can solve the problem of merging the vehicles."

"Okay, no problem. I'll contact him right away."

When Lin Bin called the Laoqu Diesel Engine Factory, Wu Shengli was conducting research here.

"Leader Wu, our factory was founded in 1955. It was one of the 156 key projects during the First Five-Year Plan period. It is now one of the 665 backbone enterprises in our domestic machinery industry." Factory Director Wang Tianmin introduced to Wu Shengli with excitement: "At present, our factory is already a professional manufacturer of medium- and high-speed high-power diesel engines for ships and a complete set of diesel generator sets."

There are many marine diesel engine factories in China, each with its own characteristics. For example, Bincheng manufactures low-speed diesel engines, while they manufacture medium- and high-speed diesel engines.

Although it is called the Laoqu Factory, in fact, they are not in the provincial capital, but in Xingping City, 50 kilometers away from the provincial capital.

Wu Shengli was very enthusiastic about the project proposed by Qin Tao. This was definitely not because Qin Tao was his son-in-law, but because Qin Tao proposed a low-cost advanced frigate project to the Navy, which was of great significance to the Navy.

After it was proposed at the Navy meeting, relevant technicians began to question the problem of diesel engine paralleling, so Wu Shengli took a break and came here to seek a solution.

"Since 1978, we have introduced the PA6 series diesel engines of the French Thermal Engine Association. Now we can produce related products, ranging from six cylinders to sixteen cylinders. However, we do not have relevant information on this STC technology, and we cannot solve the problem of diesel engine paralleling."

Wu Shengli nodded: "I have heard from the technicians in the capital that if you want to parallel two diesel engines of the same power to drive a propeller, it is very difficult from a technical point of view."

"Yes, there is no precedent in the world for the time being." Wang Tianmin said: "So, although we are very confident in our diesel engines, we are still cautious in this regard. Perhaps, President Qin is very capable and has a way to solve the relevant problems."

Wu Shengli's expression was serious: "Yes, there is no precedent in the world, but with our current strength, when the gas turbine cannot be broken through for the time being, diesel engines are our most suitable solution."

If there are advanced gas turbines in China, why would there be so much trouble! Even if it is a little more expensive, it is enough to use gas turbines directly. In fact, some countries use full fuel power.

We are still far behind. Even if we make it in China, it has high fuel consumption and low lifespan, and it can't be used on ships at all.

"Director Wang, Bincheng Diesel Engine Factory called." At this time, a secretary whispered in Wang Tianmin's ear.

So, Wang Tianmin picked up the phone, pressed a button, turned the phone over, and then heard the voice inside.

"Boss Qin has visited me and helped me a lot. He said that the plan for the vehicle combination has been prepared and you need to provide relevant information about the diesel engine."

"The plan for the vehicle combination has been prepared?" Wang Tianmin was extremely surprised.

After hanging up the phone, he was very excited. Wu Shengli was there, smiling. Qin Tao had never let him down! Since Qin Tao said it was okay, it must be okay!

"It seems that I have to go to Mingzhou to take a look."

Wu Shengli said to himself. On the one hand, he wanted to listen to Qin Tao's report to see how the vehicle combination problem was solved. On the other hand, he wanted to see the anti-aircraft ship under construction to see how the progress was.

"I'll go too and send information to Boss Qin and others!" Wang Tianmin was also very enthusiastic.

For Wang Tianmin, Qin Tao solved the vehicle combination problem, which meant that their diesel engines could be mass-produced.

This is not an ordinary automotive diesel engine. The monthly demand is tens of thousands of units. The monthly output of large marine diesel engines is often in the single digits, and some even produce only one every few months. From the establishment of the factory to now, they have only produced about 500 marine diesel engines. If there are a large number of orders, it means that their income can be multiplied several times!

So, when Qin Tao came back from Bincheng, coordinated the production of new parts in Huating, and then rushed back to Mingzhou, a large group of people also came from the remote old district diesel engine factory.

"Dad, why are you here?" Qin Tao was extremely surprised when he saw Wu Shengli.

"Well, I heard that there is already a plan for diesel engine integration here, so I came to take a look." Wu Shengli said.

Heard? Qin Tao looked at the people wearing work clothes from the Laoqu Diesel Engine Factory again, and understood something in his heart: "Are you conducting research at the Laoqu Factory?"

"Yes."

"I just came back, and I don't know the specific progress. Let's ask our technicians to introduce it." Qin Tao said: "However, these technologies are under development and have not yet applied for patents, so please pay attention to confidentiality discipline."

Wu Shengli nodded: "If anyone dares to leak the secrets, the Navy will investigate it to the end."

For the Laoqu Diesel Engine Factory, no matter which shipyard wins the bid, it will not affect them. They don't need to leak the technology. Moreover, Qin Tao wants to use their diesel engines, which is good for them.

In addition to Wu Shengli's words, anyone who dares to leak the secrets is very bold.

"We have given the research and development of this parallel car to researcher Zhang Chao, who is from Tsinghua University and has strong capabilities."

Wang Tianmin was left with only surprise and emotion.

Qin Tao said he wanted to apply for a patent, which shocked him. Now, he was even more shocked to hear that there were top students from Tsinghua University here. This Mingzhou Shipyard is really a place with hidden talents!

In the conference room, Zhang Chao was also very excited. He opened his notebook and typed the design plan on the screen.

Qin Tao only gave a suggestion at the beginning, but now Zhang Chao has designed the plan based on the specific performance of the diesel engine and his own needs.

Looking at the precise mechanical perspective, Wang Tianmin felt like Liu Laolao entering the Grand View Garden, everything was fresh.

"In theory, this plan is feasible, but you haven't received our technical information yet. How did you start the preliminary design?" After listening to the exquisite design, Wang Tianmin expressed affirmation and also raised questions.

"We designed it based on the STC diesel engine technical information of the French Thermal Engine Association. After all, what we have to match in the end is this kind of diesel engine."

Now it was Wang Tianmin's turn to be embarrassed. They haven't made this kind of diesel engine yet!

"In other words, this technology can realize the parallel operation of diesel engines?" Wu Shengli didn't understand these specific technologies, but he could ask people around him. Now it seems that this technical route should be feasible.

"Yes, it is completely possible. Even if a reduction gear is added on the side, this device can also realize the parallel operation with the gas turbine." Wang Tianmin said.

The design is too clever, especially the clutch, which is absolutely innovative. No wonder they want to apply for a patent!

"Then the next step is to make the machine and conduct a two-hundred-hour test run on land. If the test run is normal, it means that this technology can be used to drive frigates. In the future, all our frigates can use this power system!" Wu Shengli was also very happy and made the decision immediately.

"Leader Wu, we don't have this STC diesel engine yet." Wang Tianmin reminded in a low voice.

Here is to build a mechanism for paralleling. They want to build a diesel engine. Now they don't have STC technology, how can they experiment?

"We have plans to use this power for the ships we build for customers. The French imported diesel engines will arrive soon. At that time, we will find a way to disassemble the turbocharger inside and then imitate it." Qin Tao said: "At the same time, due to the increase in power, you also need to strengthen the relevant mechanisms of the engine, such as pistons, crankshafts, connecting rods, etc."

Wang Tianmin frowned.

Qin Tao is right.

Adding a turbocharger to the engine will rapidly improve the performance of the engine, but at the same time, this way of squeezing power will also cause some damage to the engine, and the relevant mechanisms need to be strengthened.

Originally, the single cylinder had 400 horsepower, and now it wants to be increased to nearly 500 horsepower, which requires the strengthening of various related mechanisms!

How to strengthen?

"You can learn from the technology of MTU diesel engines, and at the same time, introduce some new equipment and improve your production line. For you, this is also an opportunity for leapfrogging development." Qin Tao began to make requirements: "For example, in terms of casting, the world has begun to use resin sand molding production lines, so that the cast cylinder will be more precise and can withstand stronger impact. In other parts, you also need to have a special processing center to improve the precision."

Low-speed diesel engines rely on large volume and do not require high strength, but this kind of medium- and high-speed diesel engine is different. Qin Tao put forward the requirement of product upgrade to them, only in this way can the needs of 4,000-ton frigates be met.

"Mr. Qin, these improvements require a lot of funds!" Wang Tianmin looked distressed.

"You can learn from Bincheng Diesel Engine Factory." Qin Tao said: "The god of machine manufacturing in the island country is doing research there. With only 5 million US dollars, you can complete the upgrade and transformation requirements for their production line. You may also be able to spend less money and do big things."

"But we don't even have 5 million US dollars." Wang Tianmin was very frustrated: "How can we compare with Bincheng Diesel Engine Factory?"

Bincheng Diesel Engine Factory produces low-speed marine diesel engines. In the current shipping market, 90% of cargo ships are equipped with this type of engine.

And their Laoqu Diesel Engine Factory produces medium- and high-speed marine diesel engines. Most of these are used to match warships. Now the domestic warship production is small. Although their factory was established during the First Five-Year Plan, it is now just trying to survive.

Moreover, their factory is still in the inland area, which is not comparable to the coastal area. They can't even take out 5 million!

Comparing people is annoying.

"If we use the factory's assets as collateral and borrow money from the bank without upgrading and transformation, we will definitely fall behind in the future and may be eliminated in the market competition." Qin Tao said.

"Mr. Qin, it's difficult to borrow money, and it's five million US dollars, which is foreign exchange." Wang Tianmin said: "We are not as rich as your Minnesota Shipbuilding Industry Group."

At this point, Wang Tianmin suddenly remembered something: "Mr. Qin, can you provide us with money?"

Of course not, my money is not blown by the wind, Qin Tao thought so in his heart, but in order not to hurt the other party's self-esteem, he did not say it.

However, Wang Tianmin's next words made Qin Tao happy: "If you are willing, we are willing to sell part of the factory's shares."

"You mean, we use the method of injecting funds to invest in your Laoqu Diesel Engine Factory?" Qin Tao did not expect that there would be such a good thing that fell from the sky.
