big country car

A brand-new car was parked in a special parking space for factory leaders. The front hood had been opened, and the driver Zhao Changhai was staring at the engine part of the nose. As an auto soldier who had participated in the southern border war, Zhao Changhai His technology is quite superb, the car under his hands has never had any failures, but now, looking at the engine part, he can only be confused and can't find where to start!

Compared with the other Santanas in the parking space, this car looks more high-end and atmospheric. The black paint surface of the car shines brightly in the morning sun. The transition is smooth, it looks very natural, and it is also very stylish.

On the front face of the car, the logo of four circles is so high-end, representing its most distinguished status: Audi!

Qin Shaoyou accompanied Master Liu Shengli to the front of this car. When Master Liu greeted the driver Xiao Zhao, Qin Shaoyou looked at this car and couldn't help but sigh in his heart. As the most famous automobile engineer in later generations, Qin Shaoyou's garage Here, he collects quite a few classic cars, and this third-generation Audi model is also one of his collections.

In this era, Audi does not have the classification of a*. It is classified according to its own power. This third-generation Audi has two types, Audi 80 and Audi 90, which represent its power of 80 horsepower and 90 horsepower respectively. In this era when Alto Jr. only had 100 or [-] horsepower, a car with nearly [-] horsepower was definitely a high-end product.Later, FAW in the north produced the Audi [-], which became a generation of classic official cars.

Qin Shaoyou walked around the car, and the Audi 90 logo was printed on the trunk of the car, indicating that it was the latest high-end Audi model!

It's better to have a car factory in City S, and to form a joint venture with Volkswagen, you can also get a quick start. If you import this kind of car and use it as a car for the factory leaders, many provincial leaders may be envious after seeing it.

Qin Shaoyou turned around again and began to drool over the interior of the car.

Leather seats, cassette-type car audio system, button-type central control...

"Master Liu, the car won't start, and I don't know why." At this time, Zhao Changhai was anxiously introducing the situation of the car to Liu Shengli.

"Can the horn and lights work?" Liu Shengli asked.

"The horn doesn't sound and the lights don't turn on, and we're looking for a fault under the buttocks. Can we not know about this?" Zhao Changhai said: "The horn and lights are fine, and the circuit of the battery must be fine."

"Have you checked the distributor? Did the distributor catch fire?" Liu Shengli continued to ask.

"No."

"Then check quickly." Liu Shengli said.

While talking, he went to find the location of the distributor. At the same time, he was also a little curious. Zhao Changhai is also an old driver. Why can't he even handle this problem?

However, he looked left and right, but he didn't see the location of the distributor.

"Old Zhao, hurry up and find out where the distributor is." Liu Shengli said.

"Master Liu, this car doesn't have a distributor." Zhao Changhai said, "It's different from our previous car."

"What? No distributor? Could it be a diesel car?" Liu Shengli was also taken aback.

"No, this car uses an EFI engine." Zhao Changhai said, "Have you seen that? Inside is the computer of the engine, which injects fuel and ignites and burns. They are all controlled by that thing, no need Distributor."

What?EFI engine?When he heard this, Liu Shengli's face suddenly changed. We have never repaired this thing!

Master Liu has been in the factory for more than 20 years. From the Hongqi sedan to the current Santana, he is very skilled in troubleshooting various vehicles. However, those are old calendars. Times are developing and technology is improving. Yes, something as tall as a computer has also been moved into the car, and the computer is used to control the operation of the engine. Of course, this thing is very tall.I heard that once something goes wrong, you have to plug in the computer and use the computer to read the data to know what went wrong.

Now, looking at the clean and tidy engine compartment, Liu Shengli began to retreat in his heart. Why did he come to repair the car without asking clearly?If the repair is not good and the factory manager is delayed in using the car, it will definitely leave a bad impression on the factory manager!

"Master Liu, has the car been repaired?" At this moment, Zhang Guangming ran over. It was early in the morning, and before it was hot, sweat was already protruding from his forehead.

"This..." Master Liu thought to himself, maybe it can't be repaired for the time being, there are still a few Santanas beside here, do you want the factory manager to take the Santana?

Liu Shengli was thinking about how to speak, Zhang Guangming continued: "The factory director said, this time we are going to discuss business with foreigners, and driving our Audi 90 can also demonstrate the strength of our factory. I have already broken down the car. I told him about it, and the factory manager heard that you came to repair it, and he was very confident, saying that there is no car that you, Master Liu, can't repair."

Come on, with such a high hat on, Liu Shengli can only swallow back what he originally wanted to say, he has to fix it, and he has to fix it.But, the problem is, I don’t know how to fix it myself!This is the first time Liu Shengli has seen this electronically injected engine. He doesn't know how to start with something controlled by a computer.

"Master Liu, the factory manager is about to use the car in 10 minutes at most, so hurry up!" Zhang Guangming said, "I still have to go to the concierge to get some materials sent by mail. I have to run away early in the morning." Broken leg."

As Zhang Guangming said, he left in a hurry. Looking at Zhang Guangming's leaving back, Liu Shengli's face was extremely ugly, and he regretted it a long time ago. This is muddy water, and it shouldn't be touched at all.

Now, what should I do?Liu Shengli looked at the engine compartment and felt like crying.

"Master Liu, when I was in technical school, I read a few books on EFI engines." At this moment, Qin Shaoyou suddenly said from the side: "This EFI engine sounds amazing, but it's actually not complicated. Many faults are just small problems. For example, if the wiring harness of a certain sensor is not in good contact, the signal transmission will not be smooth. If the computer cannot receive the signal, it will not work. Should we disassemble the connectors of those wiring harnesses and then reconnect them? Get up and try?"

This Audi 90 has already started to use electronic fuel injection engines. In this era, it is very high-end. However, one of the batches of vehicles used unqualified connectors, resulting in poor contact. Later, the Audi factory recalled them.

Now, this new car has a breakdown, which is probably caused by this unqualified connector. Qin Shaoyou just couldn't remove the wiring harness of the engine speed and crankshaft position sensor because of his status.
