Chapter 185: Our diesel engine is the best in the world
Nanyang Diesel Engine Factory, conference room.
The two sides sat on each side, and they were supposed to start the verbal negotiations, but now Huang Youxian was a little cautious. The sudden appearance of Mr. Qin put a lot of pressure on Huang Youxian. He didn't even dare to express his position easily to avoid making mistakes.
"We and you are neighbors separated by a strip of water. Since the establishment of diplomatic relations in the 1990s, our relationship has been deepening. Our Mingzhou Group entered the electronics industry and we also cooperated with Sanxing Electronics. When I see you, it's like
It’s like seeing a relative.”
"Yes, we are all of the yellow race and should have cooperated with each other."
"Over the years, our shipbuilding industry in East Asia has developed rapidly. We are in a competitive relationship with each other, but there will also be cooperation." Qin Tao said: "When we first built natural gas ships, we also imported parts from you.
, now that you are importing engines from us, it fully reflects the beautiful situation of our win-win cooperation."
Yes, there is cooperation, but it is still very touching to change from the exporter to the importer. However, this is not because our own side cannot produce, but because the construction period is too tight. Thinking of this, Huang Youxian got up again.
gained courage.
That’s right, we are not inferior to the Orientals, we have also developed a brand new liquid cargo fence system!
"Yes, Mr. Qin, we have developed a new liquid cargo fence system. We gave up the expensive Yinwa steel and chose the cheaper high manganese steel. Therefore, our quotation is much lower than your natural gas carrier. In the future
You can also choose our patented technology to reduce costs and improve competitiveness."
"Yes, you are really awesome!" Qin Tao gave the other party enough face: "Your choice of high manganese steel is a pioneering work and a leap in liquefied gas ship technology! When we complete this batch of orders, we will definitely
We also need to delve into high manganese steel or other steel technologies. Our patents are too old and we need to innovate."
"So, let's talk about the engine introduction project next? What we are building is a 170,000 cubic meter liquefied gas ship. This kind of ship requires 40,000 horsepower. I wonder if you can provide us with a suitable engine here."
Liquefied natural gas is not heavy, with a density of only about 0.43 to 0.47 kilograms per cubic meter. Therefore, 170,000 cubic meters of liquefied gas is less than 80,000 tons. Adding the weight of the entire hull, it is still within 100,000 tons. This kind of
For a first-class cargo ship, 40,000 horsepower is enough, but too much is a waste. The speed of more than ten knots is swaying slowly, and there is no need to reach twenty or thirty knots.
"We have the most advanced dual-fuel engine on hand, model CHD18V51, with a single engine of 23,861 horsepower. Two engines can provide 47,700 horsepower, which is enough for your use."
This was even higher than the other party's requirements. However, after hearing Zhang Yuzhan's words, Huang Youxian shook his head: "No, no, we need one engine. Two engines are too wasteful!"
For cargo ships, the fewer the number of engines, the better. This saves money. If you can use one, it is best to use one. If it is a low-speed engine, it does not even need a reducer and directly drives the propeller. The structure is simple and cheap.
durable.
However, if the power is insufficient, then the only option is to use multiple machines.
"Our liquefied gas ships have always used this type of engine. We believe that two engines are more suitable than one." Zhang Yuzhan said: "For natural gas ships, they are all one-way cargo, and they are empty when they return.
Only one engine can be used, which can greatly save fuel consumption on the return journey."
If it is a cargo ship, it will be heavy-loaded back and forth, so there will be no difference. However, oil tankers and natural gas ships are all one-way cargo. After unloading, they are vented for loading. An empty ship does not require too much horsepower, and more is a waste of fuel.
Therefore, some marine diesel engines have a cylinder deactivation function. When the ship is empty, half or more of the cylinders are shut down, leaving only a few cylinders working.
Now, the same purpose can be achieved by using two engines. One is turned on by an empty ship. Anyway, the medium-speed diesel engine must be connected to the propeller behind through a reduction gear. The two engines drive a reducer and drive a propeller.
, is also a common form of cargo ships. Freighters never need twin-shaft sculls because they consume fuel.
"No, we still hope to have a single engine." Huang Youxian continued to shake his head: "We believe that two engines are too complicated and unfriendly to shipowners. We cannot accept this solution unless..."
"Unless what?"
"Unless your engine can be reduced to a reasonable price," Huang Youxian said, "we will consider purchasing your engine. Otherwise, we will have to go to other diesel engine factories, or even go to Europe to seek advanced engines."
This guy actually wants to use this method to lower the price!
In the past, Europe's Wärtsilä engines were indeed favored by all shipowners, but later, the natural gas ships built by Mingzhou Group were equipped with their own engines, and shipyards throughout the East followed suit. Customers had no choice.
After learning about it, I found that Dongfang’s engine performance was also very good, no worse than that of Europe, so I approved it. Later, Dongfang used an advanced dual-fuel engine to send the leaked natural gas from the natural gas ship to the engine to burn it.
In order to save fuel, the owners of various natural gas ships only recognize Dongfang engines!
Now, the other party actually uses this method to blackmail!
"Our quotation for each engine is US$8 million, which is already a very generous price. If it were other customers, our quotation would be at least US$10 million." Zhang Yuzhan said: "There is no room for price reduction for our engines. If
If you feel it is not suitable, you can go to other suppliers."
Qin Tao nodded with satisfaction. His unit must have this kind of courage. We warmly welcome foreigners to take the initiative to purchase. However, if you want to use various methods to lower the price, forget it. We will not accept counter-offers!
This chapter is not over yet, please click on the next page to continue reading! We have our own confidence, and customers cannot find a more suitable one without us!
Huang Youxian was stunned for a moment.
Yes, he really wanted to lower the price. Dongfang's engines are technologically advanced, and even their own marine engines cannot compare with them. This time, of course, it was because domestic supporting manufacturers were unable to complete the order, but why didn't they want to contact Dongfang?
What is the idea of using marine engines and then acquiring the above technology?
They just want to lower the price out of habit, but they didn't expect that the other party won't tolerate their problem at all!
Qin Tao stood up and stretched out his hand: "Okay, since you want to go to other suppliers to have a look, then go and have a look. There is an old saying in the East that business is not about favors. We are still good
Friends, you are welcome to visit the East often in the future."
What is this? Just chasing away guests?
Looking at Qin Tao's extended hand, Huang Youxian did not take it. If they shook hands together, they would have left the table.
"Mr. Qin, please wait a moment, let's talk again." Huang Youxian said awkwardly: "We are very satisfied with your engine. Can you provide us with one first and let us try it out?"
"I'm sorry, every one of our engines is produced according to the order. We use our many years of reputation as a guarantee that the quality of the engines exported to you is absolutely the first and does not require any testing." Zhang Yuzhan said: "Moreover, the engines exported to you are of the highest quality."
For the engine, you can only be responsible for the installation, and we need to carry out the startup and debugging.”
Will you do it?
Huang Youxian frowned, there seemed to be a problem here!
Suddenly, his mind thought about the French thing that had been circulated in the industry, and he suddenly became excited: "Does your engine require a power-on password when starting it for the first time?"
This is how the French were fooled at the beginning. They just thought that since a simple gas turbine had been imported, they had the right to choose where to install it. Unexpectedly, after the installation was completed and waiting for the test run, they actually asked for a power-on password!
Are Orientals too dark?
"Yes, we are doing this to avoid trouble for shipyards and customers. Our engine is a dual-fuel engine with various sensors inside, which requires precise control by the ECU. Our technicians will come to debug in person. The power-on password is to avoid
Shipyards and shipowners started the engine in advance, which ultimately led to engine accidents. After all, the first start of the engine is the most important because it will learn on its own."
Qin Tao was very satisfied on the side. These units under him learned very quickly. He asked them to tamper with the gas turbine, and their diesel engine factory also learned it. In this way, it is impossible for foreign customers to take it apart for research, because as long as it is taken apart,
Okay, that's just a pile of scrap metal!
There must be various sensors inside that can monitor whether the engine has been disassembled. Dongfang has this technology.
In other words, if they buy this engine back, they can only install it on an exported natural gas ship, and it is impossible to disassemble this engine and study it.
Do I need to purchase it if it is only for shipment?
Of course, those liquefied gas ships are still waiting!
Huang Youxian gritted his teeth: "Okay, then we will order four units first. We hope to deliver them as soon as possible."
"It has to be based on the order of orders." Zhang Yuzhan said: "We currently have more than 20 orders for this engine. If you place an order now, you have to be behind them. It will be delivered to you around March next year.
."
"No, it's too late. We have to move forward, no later than the end of this year!"
"If this is the case, then you need to add money." Zhang Yuzhan said: "Every month in advance, one million will be added. If it is three months in advance, each unit will have to add three million."
"How could you do this?" Huang Youxian was angry.
"Because we have to work in advance, our workers need to work overtime. Overtime work requires additional overtime pay. Moreover, many of our parts are provided by relevant units. If we want them to oversupply, they will have to pay extra. We want these
The money is not a embarrassment to you, but because of the increase in costs, I suggest that you still follow our production schedule. Didn't you start construction on four ships at the same time? Install your engines first and provide them to customers, and then we will
arrive."
Huang Youxian had a complicated expression on his face. He thought for a long time and then said, "Can we know the details of your engine?"
"Of course, we have the user manual here, in English."
Huang Youxian picked up the user manual and looked at the data on it.
This is not a model, but the entire V51 series of engines, ranging from 12 cylinders to 18 cylinders. The engine power ranges from 11,700 kilowatts to 17,550 kilowatts. It spans a wide range and can almost meet the needs of ships with different displacements.
Fuel consumption is also very low, especially with dual-fuel engines, etc.!
Huang Youxian saw a certain parameter and asked in surprise: "Can your dual-fuel engine also be used with mixed fuel?"
General dual-fuel engines also use a certain fuel alone, such as diesel alone or natural gas alone. Taxi engines are an obvious example. You can use natural gas first, wait until the natural gas is burned out, and then switch to gasoline.
, after all, the taxi’s CNG gas tank is not dense enough and has a limited cruising range.
The engine can use a certain type of fuel alone and be controlled by a separate ECU program. This is also a common practice in the world, but the Dongfang engine in front of you can actually be used in a mixture!
The complexity of the mixed use is greatly increased. How much diesel is put in and how much natural gas is paired with it? If it is less, it will cause insufficient power, if more it will cause cylinder explosion, and it can be adjusted dynamically at all times. This is simply alien technology!
"Yes, this is our original technology." Zhang Yuzhan said: "We have noticed that the greenhouse gases caused by the development of global shipping are gradually increasing, so we have to solve the problem of greenhouse gas emissions from ships. Conventional purification and recovery devices are difficult to
To solve the need for energy conservation and emission reduction, we have studied this brand-new technology."
In order to make the exhaust gas meet the standard, many engines will use EGR technology, which is to redirect part of the exhaust gas from the exhaust pipe into the engine and burn it again, which will be much cleaner. However, this does not completely solve the problem, and we still have to start with the fuel itself.
"Conventional diesel engines emit high pollution. The solution we provide is to add natural gas and mix it for combustion. Although there are no strict international standards yet, we are very strict with ourselves. Our technology can make diesel engines
The pollutants have dropped to one-tenth or even more than before. Of course, in addition to contributing to environmental protection, this engine technology has more practical significance. It can adjust the proportion of mixed fuel according to the load.
."
The same engine will definitely have lower power when burning natural gas than burning oil. This is due to the difference in the amount of energy contained in different fuels. Although natural gas is clean, its power density is insufficient. Such mixed combustion will burn more when high loads are required.
Oil, burn more natural gas during normal navigation, and dynamically adjust it anytime and anywhere.
Huang Youxian's eyes widened when he heard this. When he was in the South Kimchi Country, he was still a little arrogant and thought that his own technology was already very advanced. After coming to the East, he realized that he was the frog in the well. Needless to say, these technologies of the South Kimchi Country.
Not even in Europe!
Dongfang is already in an absolute leadership position in this field!
After reading it, Huang Youxian took a deep breath: "We are willing to place an order to purchase four units first, while retaining the right to purchase later. I hope you can reserve production capacity for us. These four units will be delivered by March next year at the latest.
The earlier the goods are delivered, the better.”
Is this done?
Of course, Nanyang Diesel Engine Factory has the most advanced diesel engine technology, but is it still worried about not being able to sell it? When some old customers came, they just signed and placed orders without any nonsense.
Wait, did you forget something?
Huang Youxian suddenly thought of something: "I request to go to your production line to have a look. Can this request be met?"
"Of course." Qin Tao said with a smile: "Let's go, I will take you to see the crankshaft production line."
The crankshaft is one of the most complex parts in the engine, and it is also difficult to process. Qin Tao also exclaimed how wonderful it was after seeing it, not to mention the bumpkin from South Kimchi Country.
Qin Tao acted as the commentator and took Huang Youxian to the crankshaft processing workshop. Seeing the CNC machine tools inside accurately processing the crankshaft, Huang Youxian was extremely shocked: "You have fully automated the production of this kind of crankshaft?"
"Yes, we have our own advanced processing equipment."
"Do you sell this kind of equipment?"
"We don't know this, after all, it's not produced by us. We are just users." Zhang Yuzhan said: "However, this kind of processing equipment is very expensive. The internal prices we purchase ourselves are sky-high. If you want to purchase it, it will probably not be cost-effective.
, I think it’s most appropriate for you to leave the processing of the crankshaft to us and let us help with the processing.”
Even hundreds of engines a year cannot fill this crankshaft processing production line. It would be better if we could undertake some foreign production tasks to fully utilize the potential of this production line and increase some profits.
"Okay, I will introduce it to our domestic marine engine factory after I go back." Huang Youxian said.
After visiting for a long time, Huang Youxian signed the contract. After returning with the contract and asking Zheng Yishan to sign, the payment can be officially made. If the other party delays, the delivery date will be postponed according to the payment date.
After seeing Huang Youxian off, Zhang Yuzhan said with emotion: "Mr. Qin, thank you for coming and giving us some pointers in advance, otherwise we might have fallen into a trap."
Qin Tao didn't give much advice. He mainly meant one thing: delay the production schedule and let them deliver the natural gas ship equipped with its own engine first!
This is mainly to prepare for a rainy day. After all, Qin Tao has concluded that the other party's natural gas ships will break down and the high manganese steel will crack. If we deliver the engine first, if this kind of ship fails, the other party is likely to blame the engine.
I thought it was caused by excessive vibration of my own engine.
Let the ship equipped with their engine break down first, so they don't want to default on the bill.
But apart from this, everything else is Zhang Yuzhan's own idea.
"You did a great job. You were able to negotiate the foreign trade contract by yourself without our group's intervention. It's very good."
