The development of Huaxia's automobile industry in the past decade has been very fast.

There used to be a situation where the price of an Accord was more than 300,000 yuan, but now it has become an Accord for more than 200,000 yuan, and it is not so good.

Not to mention the markup.

Looking at China, there are only a handful of car companies that still need to increase prices significantly.

Against the backdrop of such drastic changes, a variety of things are happening every day.

As a relatively unfamiliar Chinese consumer, automobile recall is a relatively common content in the global automotive industry, and the relevant requirements are constantly becoming mature.

"Mr. Cao, Toyota, Honda and Volkswagen have just announced a recall of a batch of models at the same time due to a faulty fuel pump."

"The official reason for the recall is that the vehicle has a small gap between the fuel pump impeller and the impeller shell due to the deviation of the supplier's production process, the surface roughness of the impeller is large, and the gasoline sediment is easy to accumulate between the fuel pump impeller and the impeller housing, resulting in poor rotation of the impeller, poor work of the fuel pump, and in extreme cases, it may lead to the loss of power of the vehicle."

"Volkswagen, Toyota, and Honda will replace the improved fuel pump for the vehicles covered by the recall free of charge to eliminate safety hazards."

"According to our understanding, the fuel pumps of these models are all produced by Toei Denso, and the OEMs involved are probably not only Toyota, Honda and Volkswagen."

When Mi Ying reported the news to Cao Yang, she had a smile on her face.

It's a good thing that competitors have problems.

In particular, the problem is Denso's fuel pump, which is also produced by Nanshan Auto Parts.

However, until now, except for its own brands, no car company has used the fuel pump of Nanshan Auto Parts.

Several major international manufacturers, such as Denso, Bosch, Valeo and Delphi, basically monopolize the fuel pump part.

If it weren't for the emergence of Nanshan auto parts, it is estimated that independent brands such as Chery and Geely would only be able to buy from these large manufacturers.

That price is not a level at all.

"Is this a recall for the Huaxia auto market or is there a global recall?"

Cao Yang, who has heard a lot of various recall cases in later generations, is not surprised.

Objectively speaking, a car has tens of thousands of parts, and it is not particularly strange that some parts have a little problem.

However, in the past ten years, recall cases in the Huaxia automobile market are relatively rare.

There are many reasons for this.

"Mr. Cao, this time it is a synchronous recall of the global problem fuel pump, not a separate Huaxia automobile market."

When Mi Ying was preparing to report the news to Cao Yang, she had obviously made some preparations specifically for the questions that Cao Yang might ask.

It's all a must for a secretary.

"Didn't those car companies like to play double standards in the past?"

"Why are you so conscious this time?"

Cao Yang asked, thinking about what benefits this recall case could bring to Nanshan Group.

"Mr. Cao, behind this matter, there may also be some of our efforts in it."

Dai Hanbiao next to him took Cao Yang's question and began to explain.

"In 2004, the General Administration of Quality Supervision, Inspection and Quarantine and other four ministries and commissions jointly issued the "Regulations on the Management of Recall of Defective Automobile Products", marking the beginning of the implementation of automobile product recall management in Huaxia.

"Over the years, many car companies have had overseas recalls, but there have been no cases of recalls in China."

"When I asked them why, they said they were using different parts."

"But this is all an excuse, those car companies will not be willing to develop some better parts for Huaxia alone."

"Therefore, we are also United Autohome, and in response to some defects in the market, we have complained to the General Administration of Quality Supervision, Inspection and Quarantine, hoping to promote the implementation of the recall action of the main engine factory as soon as possible."

"The problem with Toyota's fuel pump is also one of the more obvious problems."

"We've also made some efforts behind the scenes."

Dai Hanbiao's explanation was a bit vague, but Cao Yang generally understood.

He didn't bother to ask for too much detail.

As a leader, sometimes you ask too carefully, especially about some marginal things, which is not a good thing.

"What type of recall is their car recall this time?"

Cao Yang did not bother with what Dai Hanbiao did, but further confirmed the recall of the fuel pump this time.

in order to make further judgments.

"According to the relevant domestic regulations, the current automotive product recall system recall methods are different, according to the certification and recall methods can be divided into autonomous, mandatory and autonomous compulsory combination."

"Autonomous vehicle recall refers to the company's own R&D and production in accordance with the standards proposed by the state, and the company bears full responsibility."

"The state conducts spot checks on the quality of the market, and if it finds the existence of defective automobile products, it will enter the relevant procedures of automobile recall management, which encourages active recalls and eliminates the impact of defects, and represents the country as the United States, which is basically this kind of recall."

"Compulsory car recall refers to the national manufacturer to put forward the product standards, and to the relevant national agencies for certification, after passing to ensure product standards and production consistency, can be put into large-scale production and use, the state to the society to take responsibility, to ensure the safe use of the car, most countries in Europe and Dongying adopt compulsory certification."

"After referring to the models of countries such as the United States and Dongying, Huaxia uses the independent and compulsory combination of the company's own defects to propose a recall and a recall according to national directives."

"This time Toyota, Honda and Volkswagen will initiate a recall of fuel pumps, and part of the reason must be that the General Administration has put pressure on them to initiate a recall."

"But judging from the final implementation results, it is equivalent to the model of independent recall by enterprises."

What Dai Hanbiao said was a bit winding, but Cao Yang also understood it.

To put it bluntly, few car companies are willing to take the initiative to do the matter of car recall.

At this time, you can only rely on coercion.

However, Huaxia also hopes that the automobile industry can develop rapidly, so it does not want to resort to coercive measures at every turn, which will make some car companies unnecessarily worried about the prospects of the Huaxia automobile market.

In the end, there was a recall method that was different from the way of countries such as the United States and Dongying.

"Denso should be the industry leader in the global fuel pump market, and after this accident, some car companies should also be concerned about continuing to use Denso's fuel pumps."

"In addition to Toyota, Volkswagen and Honda should consider introducing some new fuel pump manufacturers."

"This is an opportunity for Nanshan Auto Parts, an opportunity for Volkswagen and Honda to consider using our fuel pumps."

"At the same time, we can also take this opportunity to see if we can enter the fuel pump supply chain of General Motors, Ford Motor and Mercedes-Benz, BMW and other auto companies."

Cao Yang's words were not at all unexpected by Dai Hanbiao.

Dai Hanbiao himself thinks the same way.

Soon, Dai Hanbiao personally took the technical team of the fuel pump to start various business trip modes and personally go to sell.

After all, for Nanshan Auto Parts, this is a good opportunity to break through the supply chain of functional parts in international manufacturers.

The role of the fuel pump is to draw gasoline out of the tank and pressure it through the line and the gasoline filter into the float chamber of the carburetor.

Thanks to the fuel pump, the car's fuel tank can be placed at the rear of the car, away from the engine, and at a lower position than the engine.

Early automotive systems used mechanical fuel pumps driven by engine camshafts.

Modern vehicles often employ electric fuel pumps, which provide better control and reliability.

Electric fuel pumps come in a variety of designs, but there are two types that are popular in modern cars: in-tank fuel pumps and in-line fuel pumps.

The fuel pump inside the tank is submerged directly in the tank, providing an inherent noise damping characteristic, and submersion in the fuel reduces the noise generated by the pump during operation for a quieter driving experience.

When the vehicle is idle for a long time or runs out of fuel, the fuel line will become empty, making it difficult to start.

The fuel pump helps start the fuel system by filling the lines and restoring the fuel pressure, making it easier to start the engine.

Basically, passenger cars use this type of fuel pump.

On the other hand, in-line fuel pumps are mounted externally, usually near the fuel tank or along the side of the cabin, as is the case with some commercial vehicles.

The fuel pumps produced by Nanshan Auto Parts are currently electric fuel pumps placed in the fuel tank.

"Manager Li, our electric fuel pump works according to the positive displacement principle, when the power is supplied, the motor of the pump starts, creates a vacuum, and draws fuel from the fuel tank through the inlet valve."

"Fuel flows through the fuel line to the engine through an outlet valve actuated by a piston or diaphragm."

"There are several factors that influence the design of the fuel pump during this process, including the vehicle's engine specifications, fuel type and required fuel flow."

"The efficiency and durability of the pump are also crucial considerations."

"Manufacturers have to strike a balance between cost-effectiveness and meeting the required performance standards......

Dai Hanbiao's first stop was not Yangcheng Toyota, nor Yangcheng Toyota, but chose the magic capital Volkswagen.

Compared with Toyota and Honda, the main engine factories in Europe and the United States have done relatively well in terms of the openness of the supply chain.

Dai Hanbiao thinks that it will be easier to make some breakthroughs in the magic capital Volkswagen first, and then go to other car companies to promote.

"Fuel pumps are designed to operate within a specific temperature range, reducing the risk of air blockage and ensuring continuous fuel delivery even under harsh conditions."

"This time, Denso's fuel pump was recalled because it would fail under special operating conditions."

"Do you have any different measures in this regard?"

Li Jianfeng naturally knows very well what the purpose of the people from Nanshan Auto Parts came to visit today.

As a group of people who finally dealt with Nanshan Group, Li Jianfeng had a good impression of Nanshan Group.

But he also knows that the relationship between Volkswagen and Nanshan Group is not good, and there are even many contradictions.

So unless the fuel pump of Nanshan Auto Parts has a technical and cost advantage that people have no way to refuse, otherwise he thinks that Modu Volkswagen will not use the fuel pump of the other party.

"The key part of the oil pump is the plunger, and the plunger and plunger sleeve are very precisely machined accessories."

"There is an inclined groove in the plunger sleeve, and there are small holes in the plunger sleeve called the suction inlet, which is filled with gasoline."

"When the plunger tilts the groove against the suction inlet, the gasoline enters the plunger sleeve."

"When the plunger is pushed up to a certain height by the camshaft, the plunger tilt groove is staggered with the suction inlet, and the suction inlet is closed, so that the gasoline can neither be sucked in nor pressed out."

"At this time, when the plunger continues to rise, it compresses the gasoline, and the gasoline pressure reaches a certain level, and the check valve will swarm out and enter the oil pipe."

"When the plunger rises to the top dead center and moves down, the plunger tilt groove meets the suction inlet again, and the gasoline is sucked into the plunger sleeve, repeating the above action again."

"This process requires the plunger to maintain a very high level of machining accuracy and wear resistance at all times, without any accidents."

"Our plunger uses high-standard special steel produced by Nanshan Special Steel, and its wear resistance, strength, corrosion resistance and other related properties are better than those used by other manufacturers."

"In addition, we use a CNC five-axis machine tool customized by Nanshan Equipment to process the plunger, and the machining accuracy of the parts is very high, which is not comparable to other competitors."

"Up to now, our fuel pump has been used in many car companies, including Xingchen Automobile, and the supply volume has already exceeded 1 million units."

"There were no problems or complaints during this period, and the quality was completely tested."

"The most important thing is that while maintaining high quality, our fuel pumps cost 20% less than other manufacturers such as Denso."

"And all our components are produced in China, once there is a model change, there is no need to worry about some sluggish materials."

"It's a different story, like Denso."

"As far as we know, although their fuel pumps are made in Yangcheng, eighty percent of the components are still imported from Dongying, the United States or Southeast Asia."

"Even if it is a so-called domestic component, the raw materials are imported from Dongying."

"Even I heard that their individual parts are produced in one country, processed separately in the other two countries, and finally transported to Yangcheng to assemble into an assembly."

"Under normal circumstances, this model is not a problem except for the higher cost."

"But when there's a supply crunch or you need to make last-minute design changes, it's very fatal."

"The communication in various places is not smooth, and there is a relatively large time difference, so I don't know how much time will be wasted."

Dai Hanbiao came prepared.

Li Jianfeng asked casually, and he could say a lot of truths.

The point is that these truths are still difficult to refute.

Because these things are objective facts.

"Due to the long-term immersion of the automobile fuel pump in gasoline, the material selected needs to have good oil resistance and chemical resistance.

As a professional procurement, Li Jianfeng is not so easy to be fooled.

He easily found a counterattack point in Dai Hanbiao's words.

"Manager Li, you are so professional."

"That's right, one of the biggest features of PPS is its chemical resistance, and its chemical stability performance is second only to F4."

"PPS is stable to most acids, esters, ketones, aldehydes, phenols, aliphatic hydrocarbons, aromatic hydrocarbons, chlorinated hydrocarbons, etc., and no solvent that can dissolve PPS below 200 °C has been found."

"Since the automobile fuel pump needs to cooperate with the movement of the piston and other movements, the materials that need to be selected are dimensionally stable and easy to process."

"The water absorption rate of PPS modified plastics is very small, generally only about 0.03%, and the molding shrinkage is low, even when used under high temperature and high humidity conditions, it also shows excellent dimensional stability."

"Compared with special steel, PPS material has excellent processing performance, and can be processed by different processing methods such as injection molding, extrusion, molding, etc., which can carry out secondary processing of products and avoid unnecessary waste."

"At the same time, because gasoline is flammable, the materials selected are required to be anti-static and have a good flame retardant effect."

"The inherent flame retardancy of PPS is an intrinsically flame retardant material, which makes it possible to achieve high flame retardant UL94V-0 without the addition of flame retardants."

"Even PPS has been modified to have an excellent antistatic effect."

"Therefore, the pump body of the fuel pump, PPS is the best processing material, and the PPS of our Nanshan auto parts is modified by Nanshan Chemical after purchasing the base material from the outside, and the relevant performance is better than the PPS used by any opponent on the market."

"If Manager Li is interested, we can share a copy of the relevant test report of PPS with you later."

At this time, it is time to give full play to Dai Hanbiao's professionalism.

If you don't know about the situation of the fuel pump and the situation of PPS, you are likely to be really confused when you are suddenly asked by Li Jianfeng.

Then the effect of continuing to sell will be greatly reduced.

Therefore, for the sales of the auto parts industry, they can not only understand sales, but also need to understand some technology.

This is also the reason why many auto parts companies like to rotate some personnel from the technology or project side to engage in sales.

Even the sales managers in Europe and the United States, many of them have technical backgrounds.

No matter how bad you are, you are also from an engineering background, and you have some basic understanding of these technologies.

"This time Denso's fuel pump is recalled, if this part is produced by you, what can be done to improve it?"

Regarding Dai Hanbiao's explanation, Li Jianfeng was noncommittal.

Instead, he changed to a new issue that he was most concerned about.

Although this problem does not need to be worried about by him in theory, it is something that Denso and Volkswagen's R&D personnel need to worry about.

But he also wanted to hear how Nanshan Auto Parts solved this problem.

"Manager Li, this time Denso's oil pump failed, and we don't know the specific reason."

"However, judging from the information in the recall announcement, it is because Denso has a production process deviation in the process of processing the fuel pump."

"The gap between the fuel pump impeller and the impeller shell is small, the surface roughness of the impeller is large, and the gasoline sediment is easy to accumulate between the fuel pump impeller and the impeller housing, resulting in poor rotation of the impeller, poor work of the fuel pump, and loss of power of the vehicle in extreme cases."

"In this case, in addition to the design defects, the poor machining accuracy is a very important reason."

"Especially for the processing of impellers, if the roughness is too high, nine times out of ten it is caused by the processing accuracy of the processing equipment."

"This problem will not happen at all in Nanshan Auto Parts."

"As we all know, most of the equipment of Nanshan auto parts is produced by Nanshan Equipment, a brother enterprise."

"Up to now, Nanshan Equipment's various machine tools have won the first prize of the National Science and Technology Progress Award once, the second prize three times, and countless other awards."

"Our machine tools are not bad at all compared with international advanced machine tool companies such as Yamazaki Mazak and Mori Seiki."

"The most important thing is that we are willing to put high-precision machine tools into the production of parts, so that the machining accuracy of our parts can fully meet or even exceed the requirements of the drawings."

"Therefore, if Denso's fuel pump is handed over to us, we only need to adjust the gap between the fuel pump impeller and the impeller housing, and improve the machining accuracy of the impeller, and we can completely solve the problem."

In the process of Dai Hanbiao's explanation, it is natural to step on Denso and raise Nanshan auto parts.

That's what every vendor is doing, too.

"Mr. Dai, according to your statement, this problem is actually not difficult to solve, why has it not been solved for so many years on Denso?"

Li Jianfeng's question is probably also a common problem in the hearts of many people.

However, Dai Hanbiao gave the answer easily.

I saw him cough lightly and said, "This matter is simple and simple, I'm not saying that Denso's technology is not good." ”

"As the world's leading component manufacturer, DENSO has its own unique features in many fields."

"If they really want to do a good job of the fuel pump, they can theoretically do it, otherwise you wouldn't have replaced the fuel pump after the recall."

"Denso has always been a leading fuel pump company in the industry, and its production lines and production equipment have been invested for many years."

"And at the beginning, they were reluctant to use the best equipment, which led to the fact that the parts they produced were not as high as everyone imagined."

"There are some accuracy issues that are difficult to detect in a simple test."

"It's like the roughness of the impeller is relatively high, which can eventually cause the engine to lose power, which is difficult to detect during testing."

"But once the production quantity is enough, slowly, related problems will be exposed."

"At this time, with some manufacturers with advanced technology, advanced equipment and relatively new production lines to produce related parts, the advantages will be more obvious."

Dai Hanbiao went around in a circle, still praising himself.

This also gave insight to the other colleagues who came out with him!
