Chapter 10 Santana's Fatal Flaw

s

After sitting in the conference room, Jindler was obviously very nervous and twisted uneasyly twice, seeing that there was no one around, then he asked Chen Geng in a low voice: "Chen, what are you going to say to me? Are you not allowed to go to Germany because your country does not allow you to go to Germany? Or have you been harmed by politics? If so, I will do my best to help you..."

What do you mean by this?

Chen Geng didn't expect that Jindler's association ability was so powerful that he could even think of himself being harmed by political pests. He was a little amused for a moment: What kind of political pests can I face as a student?

But this is what foreigners in this era think of China. In their opinion, Red China is a very terrifying place. Chen Geng did not help the other party reverse this view and waved his hand and said, "It's not this, I just discovered several very serious logic and calibration errors in the b2 electronic injection system..."

"Chen, are you kidding me?" Jindler was relieved when he heard that Chen Geng was talking about automobiles. Before Chen Geng finished speaking, Jindler smiled and said, "The b2 given to you by Wolf Castle is the carburetor version..."

"I know, but the European and North American versions of Santana are electronically sprayed models, and I'm talking about the North American version and the European version of b2."

Jindler was about to jump up when he heard this: "This is impossible! And you have never been exposed to the electronic spray version of b2..."

"Did you forget that there are three electronically sprayed versions of b2 at Poussan base."

Jindler, who was so excited just now, was stunned and speechless.

Wolf Castle does have three European versions of B2s in Magic, that is, the electronic injection model of Passatb2, which Chinese call Santana, and Chen Geng has indeed come into contact with these three European versions of B2s.

If this was said by others, Jindler would definitely turn around and leave without hesitation, but if this was said by Chen Geng, he would not dare not to take it to heart. Based on Jindler's understanding of Chen Geng, he knew that Chen Geng was definitely not a casual person. If Chen Geng said that there was a problem with the B2 electronic spray system, he would definitely have discovered something.

"Chen, are you sure?" Jindler's face turned pale, and he was a little scared.

"Yes, I'm sure." Chen Geng nodded affirmatively.

Chen Geng's affirmative answer made Jindler's face turn paler even more. He swallowed unconsciously and asked in a low voice: "Is that... very serious?"

Chen Geng nodded: "It's very serious. In specific situations, the system will automatically refuel when the driver is retracting the accelerator." After a pause, Chen Geng whispered: "This situation also occurs on carburetor models."

Jindler's face turned pale in an instant!

The car automatically refuels when the accelerator is reloaded, which is definitely a fatal flaw that can lead to serious car accidents!

Once this defect is made public, the blow to Wolf Castle will be fatal. For Wolf Castle, which is extremely difficult to live now, it may even make Wolf Castle bankrupt!

Realizing this serious consequence, Jindler subconsciously clenched his fists: No! This situation must not happen! I must try every means to prevent this worst situation from happening!

Some readers may ask, aren’t the cars at this time all carburetors? Could it be that the cars at this time already had electric sprays?

The answer is: yes!

With the rapid development of the automobile industry, the number of automobiles in the world has grown sharply in the 1960s. Due to the imprecise regulation of traditional carburetors, the exhaust gas emission content of automobile exhaust is too high, and the pollution to the atmosphere and the environment is becoming increasingly serious. This is an important factor in the global warming and the greenhouse effect. For this reason, the United States proposed the Musky Act as early as the 1960s, and Japan also proposed regulations to limit automobile exhaust emissions in 1968, 1973, and 1976 respectively. Europe, which attaches great importance to environmental protection, is naturally no exception.

At the same time, with the continuous advancement of electronic and electronic assembly technology, especially the rapid development of transistor and integrated circuit technology, it has provided a foundation for the full application of automotive electronic fuel injection technology in automobiles. In the 1970s, electronic injection technology has begun to be widely used in automobiles in European and American countries.

The Passatb2 is not a successful model. Apart from its good performance in the Brazilian market, not to mention North America, even in Wolfburg's base camp: Europe, the performance of the B2 is a mess.

In this case, Jindler's reaction does not seem to have to be so intense, but the worst thing is that the European and American versions of Passatb2 are equipped with the LH-jetroni hotline electronically controlled fuel injection system that Bosch just released in 1981.

This is deadly!

The lh-jetroni hotline electronically controlled fuel injection system has always been promoted by Wolfburg as its core weapon. Just as some models later promoted their cars with high profile, the biggest feature of the lh-jetroni hotline electronically controlled fuel injection system is the use of a hotline air flowmeter, among which "h" is the first letter of the English "hot" hotline. The hotline air flowmeter directly measures the intake quality, can more accurately control the air-fuel ratio, significantly improve the engine's power and economy, and significantly improve the engine's exhaust emissions.

Since the lh-jetroni hotline electronic fuel injection system has so many advantages, it is natural for Wolfburg to continue to use this system on the next generation of models. Wolfburg is developing, which is a new generation of intermediate cars that Wolfburg hopes for in the mid-range car market: this system is also equipped on Passatb3!

But now Chen Geng actually told himself that this system has serious safety hazards. If this is true, it will not only mean that the death penalty of Passatb3 is directly sentenced, but also that the death penalty of Wolf Castle in the intermediate car market is directly sentenced. It can even be said that the death penalty of Wolf Castle is announced. Do you think Jindler is afraid?

He was so scared!

He wanted to kneel on the ground and beg Chen Geng, begging him to tell him the errors in the calibration and logic of this system.

"Of course I will tell you, otherwise what I'm talking to you, but do you think this is the place to talk?" Chen Geng said helplessly.

That's right, this is the Republic's Ministry of Defense, and it is indeed not the place to speak. Jindler immediately reacted, and then he pulled Chen Geng and rushed out: "Go, let's go to the Demon City immediately."

This guy was frightened.

Chen Geng said helplessly: "Didn't Wolf Castle set up a liaison office in the capital? We just need to talk directly to the Magic City in the liaison office."

"Yes, let's go to the liaison office and go now."

………………………………

Chen Geng originally thought that he and Jindler would encounter some obstacles when they went out. After all, Jindler was a foreigner, and the saying that "Imperialism will perish my heart" is still very popular, but Li Jianguo's reaction opened his eyes: he just told Li Jianguo that he needed to take half a day off to help Mr. Jindler solve some problems. Before Chen Geng could tell him what the problem was, Li Jianguo had already agreed happily.

When he arrived at the contact office of Wolf Castle in the capital, Jindler was like a madman and asked him to arrange a conference room for himself, and then told him that as long as he didn't come out, no one would be allowed to get close to the conference room. He was anxious and asked Chen Geng what was wrong with the electronic spray system on B2.

Chen Geng didn't hide it and said happily: "When the engine is running at high speed for a long time and the steering system is in a continuous and high-intensity working state, there is a very high chance that the engine will automatically refuel when you collect the accelerator. This is a common problem with B2, whether it is a carburetor model or an electric injection model."

In the general understanding, whether it is an electric injection truck or a carburetor truck, we control the amount of oil entering the engine combustion chamber by controlling the accelerator. This is actually a misunderstanding. Of course, the working method of the carburetor truck is like this, but in an electric injection truck, we only control the opening of the throttle through the accelerator. The amount of oil entering the combustion chamber is controlled by the ecu from beginning to end. The ecu automatically controls the amount of oil injection through the detected air flow, so to put it more strictly, our feet control not the accelerator, but the "air door".

Under normal circumstances, the pull-line throttle will certainly not refuel when you loosen the throttle, because the cable is elastic, but this is actually easy to understand. The entire set of throttle zipper mechanisms are all mechanical components. If too much dust falls on some mechanical components, or if the temperature in the cabin is too high, the mechanical properties of components such as key springs of the zipper system will be degraded, the machine response of some parts will be stuck. When you loosen the throttle, the throttle does not decrease as you think, and even in some extreme cases, the throttle will be refueled when you loosen the throttle.

This fault is also a classic fault of Santanner B2. The reason is that the throttle control system was not considered at the beginning of the design. However, after several serious car accidents in this fault, Wolfburg solved this problem by changing the design of the throttle system in 1986. It was not until 10,000 Santanas were assembled in China. This low-probability incident naturally did not occur, or even if it occurred, it was not a problem with the car. However, Chen Geng worked in Wolfburg for many years and would not know about this typical fault of B2.

Jindler is an automotive engineer, and of course he knows that this is possible.

Holding his hair in pain, Jindler asked hoarsely: "What is the probability?"

"If I follow the test method I specified, it's about 30%.
