Rebirth of the Auto Giant

Chapter 560 Intelligent Service Management System

Subsequently, Manman's three-horsepower engine TCD6114qd equipped with the same car also stopped at the Tang Dynasty Power booth.

This was something the two parties had discussed before. As Tang Dynasty Power’s largest partner in Germany, Manman is also a manufacturer of complete engines for Tang Dynasty Power. It is also beneficial to Tang Dynasty Power’s publicity.

In the past ten years or so, Tang Dynasty Power, especially with the recognition of Man Tang Automobile’s four-cylinder diesel electronic injection engine in the market, everyone has gradually become familiar with Tang Dynasty Power, a red oriental engine manufacturer. There are

Many customers came to check it out.

The two translators from the External Liaison Office, as employees of Tang Dynasty, were also familiar with their products and began to introduce them to the guests.

“This is our company’s latest upgraded version of a six-cylinder diesel electronic injection engine specially prepared for heavy-duty trucks. It has been upgraded based on the mature technology of the original basic four-cylinder engine. The cylinder block, cylinder head, and cylinder liner adopt an integrated design.

, using high-strength molybdenum-containing cast iron material with light weight and good thermal conductivity, exquisite manufacturing technology, reliable and durable, reducing the occurrence of water and oil leakage, with more than 25% fewer parts than other similar products, and the failure rate is greatly reduced.”

The cylinder block material should have sufficient strength, good castability, heat dissipation and machinability, and should be low in price. Commonly used cylinder block materials are cast iron and alloy cast iron.

Cast iron has defects such as heavy weight, poor heat dissipation, and high friction coefficient.

This time, after twenty years of technology accumulation, Tang Dynasty Power Company introduced a new six-cylinder electronic injection diesel engine with the help of Manman Company. With the help of a number of high-tech CNC machine tools, the engine body and cylinder head were

The cylinder liner adopts an integrated design, and the body and gas liner adopt an integrated structural design without a cylinder liner, which greatly reduces leakage failures and increases the heat dissipation effect, thereby increasing the power of the engine.

This technology is now also used in conventional diesel engines.

In the past, the Tang Dynasty power engines used wet cylinder liners, that is, each cylinder had an independent cylinder liner.

In order to prevent the coolant in the wet cylinder liner water channel from entering the oil pan, sealing rings are provided on the upper and lower parts of the cylinder liner, also called water blocking rings.

The cylinder liner is the first part to withstand the high temperature caused by gas explosion. Under long-term high temperature, sometimes the rubber sealing ring loses its elasticity and causes oil water intrusion.

Later, after technical improvements, the design adopted an integrated design without a cylinder liner.

However, the design of the cylinder-less batch has particularly high requirements on the material and processing technology of the machine body.

"Integrated design is the latest technology introduced by our company, which greatly reduces the comprehensive maintenance cost of the engine, and saves more than 50% of maintenance time compared with other similar products."

"Our tcd6114qd series engines also use a technology patent invented by our company, and now have applied for an international patent, that is, in-cylinder braking technology, which increases the rated power by 25%, while saving vehicle maintenance costs, making it safer and more reliable."

"In-cylinder braking?" Many customers are experts. I heard that braking can still be performed in the cylinder?

Don’t they all rely on external brake pads and hubs for braking?

Many experts were immediately confused.

"Yes, this is the latest technology of our company. The simple truth is that when the driver releases the accelerator, when the piston is near the upper pole during the compression stroke stage, the exhaust valve opens instantly and releases High-pressure gas, close the exhaust valve, and there is very little gas in the cylinder. During the power stage, when the piston moves from the upper pole to the downward direction, the cylinder is in a negative pressure state. The gas will prevent the piston from moving downward, and the piston is equivalent to vacuuming, causing an impact on the crankshaft. The torque acts in the opposite direction, thus producing a braking effect." said the translator.

The company requires them to memorize this principle when they come, so that they can use it when the time comes.

Nowadays, all the people in the industry are enlightened when they hear it.

"When did I become like a rookie? I am a country with a large automobile industry. When did I act like a layman in front of a country like China with such a backward automobile industry?" Germany is a country with a large automobile industry and a developed automobile industry, so they I also had the feeling of seeing all the small mountains at a glance, and looking at people's momentum through colored glasses. I didn't expect to be stunned by a little girl at the booth of Tang Dynasty Dynamics.

"For those who are interested, our company's brochure also has a brief introduction." After finishing speaking, the 26-year-old German translator born in the 1970s came to the side and distributed the brochure to everyone.

The cover of the manual shows the Forbidden City and the back of the Great Wall with national characteristics, and then turn to the details page inside to find the various data of this engine and some new technologies used in the new engine, all in English.

"This brochure is very professionally designed and very beautiful. Look, this is the Forbidden City of China, the largest ancient wooden building complex in the world, with golden tiles and red walls. Look at the Great Wall. , this was built artificially more than a thousand years ago. It lies like a big snake among the high mountains..." Most locals have never been to China, but they have also heard of the Great Wall, one of the eight wonders of the world. See When I saw the Great Wall on the cover of the brochure, I was shocked by the ancient Chinese people.

Some people took a few back.

I only heard Jia Jingying continue to introduce: "The upgraded new engine adopts the intelligent management service system independently developed by our company. The company uses the GPS positioning system. We can know the specific location of your car. Of course, this is for you." If you feel that it interferes with your personal privacy, you can also choose to turn it off. We have a beginning. The electronic control unit can transmit the engine's operating mileage and time to our company's server. The background can know the specific operating mileage and hours of your engine. , the electronic control unit analyzes the data from each sensor, analyzes the results, and can intelligently diagnose the engine's operating conditions."

"The use of this technology can greatly improve the accuracy of after-sales service."

After Nong Jingying finished speaking, looking at everyone's confused look, she turned on the computer that was delivered, asked the driver on the side to start the engine, and opened the software management background installed on the computer with the "intelligent service management background".

The booths here are all connected to the Internet. After plugging in the Internet cable, after some operations, the "Intelligent Service Management Backend" was opened. Everyone gathered around and saw the backend interface. The engine number and the complete machine were written on it in both Chinese and English fonts. Number, machine brand, user name (blank), location, working time (mileage), rotation speed, water temperature, oil temperature, diesel common rail chamber oil pressure, etc. The data transmitted by each sensor to the electronic control unit is read in the background. , the last column is the failure analysis. The current failure analysis column of this engine has the word "normal" written in green font.

With the rise of the Internet and the continuous updating of technology, at the request of Wang Shi, the Technology Department of the Computer Department of Dongxi.com independently developed various big data systems.

This is one of the results of big data.

The powerful computing power allows when an engine problem occurs, the engine number or user name received from the user can be used to identify the general fault of the engine at a glance using this intelligent service management background.

The high-pressure common rail system uses more sensors than traditional diesel engines. These sensors transmit information to the electronic control unit, and the electronic control unit receives feedback information to direct each cylinder of the engine to work.

Gu Pass

If there is a problem with any sensor and the electronic control unit does not receive a feedback signal, it may be analyzed that the sensor is faulty. This will be reported in red font in the fault analysis in the last column.

For example, if the control solenoid valve on the 3-cylinder electronically controlled fuel injection product is damaged and does not move, it cannot inject fuel. If the electronic control unit does not receive a feedback signal, it will automatically determine that the electronically controlled solenoid valve of the third cylinder is faulty.

Also, if the high-pressure oil pipe is damaged and leaks oil, and the oil pressure decreases, if the electronic control unit diagnoses that the sensors in various places are normal, it may be judged that the high-pressure oil pipe is damaged.

These principles were written by Wang Shi and allowed computer technicians to write them into diagnostic programs.

"With this intelligent diagnosis system, during after-sales service, technicians can know the engine failure situation in advance and accurately prepare accessories, which greatly improves the speed of fault repair and saves time for users." Nong Jingying said.

Those present were all industry insiders, including business owners and engine expert technicians. They were very aware of the role of this large system in after-sales service.

"It's really amazing. This thing is so powerful. I can't believe that this system was developed by a company in China." The boss of an engine company nearby said, and then asked the agricultural elite: "Hello, I am Deutz Company.

The technical director of the company, my name is Kalelci Buman. We are very interested in your system. I think we can use it. I want to introduce this system. I don’t know who to talk to?" Kalerci Buman looked at Nong Jing.

Ying asked politely.

"Ah...Chairman, this is Mr. Kalerchi Buman, the Technical Director of Deutz Engine, who wants to introduce our intelligent service management system." Nong Jingying looked at Wang Shi on the side and said.

Germany's Deutz Engine Company, one of the top ten well-known engine brands in the world, is an internationally renowned engine brand. It is headquartered in Cologne on the Rhine River in Germany. It has 4 engine factories in Germany and 17 licensed production plants and cooperation companies around the world.

Factory, Deutz is mainly famous for its air-cooled diesel engines. Deutz diesel engines are used in commercial vehicles, construction machinery, forklifts, agricultural machinery, compressors, generator sets and ships, etc.

"Dear Mr. Kalerci Buman, this is the chairman of our company. He can answer your questions." Nong Jingying introduced Wang Shi to the other party.

"Oh?" Wang Shi was surprised. The engine didn't come out, but the intelligent management service system did.

"Sit down, Mr. Kalerci Buman, of course we can negotiate. If the price is satisfactory, we can launch it to the outside world, but there are some conditions." Wang Shi said.

"Hello Mr. Wang, I am very interested in your intelligent management service system. We want to apply it to our engines. I think we can go on to talk about some more specific details. What conditions does Mr. Wang have?

You can say that." Kalerci Buman said.

"Aren't you a traditional engine? Our system is mainly aimed at electronic injection engines. If it is a traditional diesel engine, it is not suitable." Wang Shi then thought of a new question.

Currently, the world's diesel EFI engine technology patents are in the hands of Tang Dynasty Power. Without its authorization, it is impossible for the other party to manufacture a diesel EFI engine.

This intelligent management service system is mainly for EFI engines.

"No, I think it can also be applied to our traditional diesel engines. We will install some more sensors, but your company will need to make some modifications." Kalerci Buman said.

"I can't think of anything else that can be added to a traditional diesel engine besides speed, water temperature, and oil temperature. Traditional engines are different from electronic injection engines. The electronic control unit receives feedback signals from various sensors, solenoid valves, etc.

The injector controls the fuel injection, but the traditional diesel engine relies on mechanical high-pressure fuel consumption, and the main opening and closing relies on the camshaft." Is this an expert? How come I don't think so?

Wang Shi looked at the other party and thought to himself.

"Uh... Well, I was really a little too excited just now. I didn't think of this." Kalerchi Buman said embarrassedly after hearing Wang Shi's analysis.

"I think, why don't we talk about the whole machine, if your company is interested in our engine." Wang Shi looked at the other party and said, "Our company has already conducted 150,000 units per year with Manman Company.

Cooperation, in the future all heavy trucks produced by Manman will be

Our products are used, and our four-cylinder engine has been used in Mantang cars for more than ten years and has been recognized by the market. I think you should be very clear about it." The cooperation with Mantang does not mean that it is not the only one.

It is impossible for Wang Shi to agree to this condition if it is guaranteed to be provided by other companies.

The more supporting manufacturers there are, the better it will be for Tang Dynasty to enter the international market.

As for output, there is no problem. The most important thing we lack is people.

Of course, we cannot compete with others on high-tech production equipment. This has to be acknowledged, but it can be added during negotiations.

"I can't make the decision on this, I will go back and mention it to the board of directors." Kalerci Buman said.

"No hurry, we still have three days." Hehe, Europe will launch Euro 3 emissions this year, and your traditional diesel engines will disappear from the stage of history. You are not in a hurry, why should I be in a hurry?

Germany's Deutz engine, Germany's MAN engine, and Germany's Mercedes-Benz MTU engine are three of the top ten well-known engine brands in the world. Both are international brands. If they can be equipped with Tang Dynasty Power engines, this will be a great influence on Tang Dynasty Power's international development.

Branding plays a very important role.

The conversation between the two was also heard by Saroyan Carter from the marketing department of Manman Company on the other side, and he immediately fed this information back to the president, Comrade Swinburne Jeff.

"This..., the contract does not say that we cannot cooperate with other manufacturers. This is unreasonable. That is Tang Dynasty Power Company's own problem and we cannot interfere." Swinburne Jeff said helplessly.

"Just do your promotion well." Swinburne Jeff explained.

"good."

On the first day of the exhibition, although the engine was not launched, many engine companies came to discuss with Wang Shi about introducing EFI technology, but Wang Shi refused.

There are also many heavy-duty truck manufacturers interested in introducing engines, such as Swedish Volvo heavy-duty trucks.

They also left their contact information. As for whether to cooperate, this will involve more specific negotiations.

Tang Chao Tractor tc8×4 negotiated with a sales company in Germany that specializes in selling tc8×4 in Germany.
