big country car

Liu Shengli nodded. Qin Shaoyou is an apprentice who can use his brain very well. When he was in the technical school, he also learned solidly.Perhaps, it can really be solved. When the time comes, let's see if these people still dare to underestimate their apprentices.

As for Zhao Mingming, he absolutely didn't believe it. He was just waiting to see Qin Shaoyou's joke, and repairing the car?In a moment, see if he knows where the engine is.

Qin Shaoyou strode towards Little Tudou, feeling a little excited in his heart.Compared with the 10,000+20 Santana, Little Tudou is definitely a national car!

Qin Shaoyou patted the front hatch, thinking of the movie starring Chen Peisi, opened the front hatch, and panicked, where is the engine?What about the engine?

Zhao Mingming, who was following behind, snickered for a while, hum, you really are an old hat, opened the hatch, and couldn't find the engine, let's see how you make a fool of yourself!

Qin Shaoyou just patted the front hatch, followed by walking to the back, and opened the engine cover quickly with his hands and feet, revealing the twin-cylinder engine inside.

Think about the three-cylinder curse of my original time and space. The three-cylinder is not wrong, but the price of the four-cylinder is wrong. Look at the two-cylinder engine used by Xiaotuo. As long as it is cheap enough, the sales will still be hot.

Seeing Qin Shaoyou skillfully opened the engine cover, Zhao Ming was a little discouraged. This Qin Shaoyou, who seemed to be familiar with Little Tudou, unexpectedly found the engine compartment in the trunk all at once.But can he fix it?

This is an air-cooled engine!

After Luo Yongwang took over, he was a little dazed. He had never repaired an air-cooled engine, so he had to replace some parts in the same way as a water-cooled engine, but it didn't solve the problem.

At this time, Liu Shengli was standing on the right side of Qin Shaoyou, looking at the engine compartment inside, and frowned a little. He hadn't repaired it before.

"We cleaned the engine cylinder head and the heat sink on the outside of the cylinder barrel, replaced it with a new cooling fan, and checked the air intake pipe, and everything was fine." Luo Yongwang stood on Qin Shaoyou's left and explained to Qin Shaoyou.

"It's an evil thing to say. If you run on the national highway, this car can run to more than 90 degrees, and the engine temperature is normal. However, in the urban area, stop and go, within 10 minutes, the engine will be high temperature. If it is idling on the spot, In 2 minutes, the engine overheated." Luo Yongwang continued to frown and said, "I really don't know where the problem is."

"I know." Qin Shaoyou said, pointing to a part: "Replace this! The problem of the high temperature of the engine will be solved!"

Hearing Qin Shaoyou's words, Luo Yongwang and Liu Shengli looked over, and then asked in surprise, "Will something go wrong with that thing?"

"Where is the problem, let me see." Zhao Ming also couldn't wait to poke his head over tomorrow. He looked at it and said, "Qin Shaoyou, you are really amazing. Master Luo and several of our apprentices have been pondering for several days, but they haven't found the fault. The reason for this, you can tell what is wrong with just one look? You are really sharp-eyed."

Of course, you have to listen to this sentence backwards. Qin Shaoyou, an apprentice, came up to take a look, and then said that there was a problem with a certain part. Isn't this nonsense?

Zhao Mingming said while reading, and then laughed: "Qin Shaoyou, are you serious? There is actually a problem with the exhaust pipe? What does it have to do with the overheating of the engine?"

"Of course it has something to do with it." Qin Shaoyou said: "The heat dissipation of the air-cooled engine is not good. The designer's main method is to enhance the air convection. Our little potato uses a special cooling fan to dissipate heat. The current exhaust The position of the trachea is wrong, after the hot exhaust gas is discharged, it is just sucked away by the cooling fan, and then blows to the engine, so the engine is blown by hot air, so it is strange if it is not high temperature."

"That's right, that's the truth, why didn't I think of it?" Luo Yongwang suddenly realized at this time, no wonder when the engine was standing still for 2 minutes, the engine became hot , the more it blows, the hotter it gets!

"Master Luo, you are just a little anxious. If you search patiently, you will definitely find the reason. Many faults are not complicated. If you are in the car business, you have to be careful." Qin Shaoyou said.

"No, master, I don't understand. If there is a problem with the exhaust pipe, it should be a design problem. Why is there a problem with this car, and the other small potatoes are not overheated?" Zhao Ming still doesn't believe Qin Shaoyou judgment.

"That's because the exhaust pipe of this little potato has been modified, it's not from the original factory at all." Qin Shaoyou said: "Brother Zhao, haven't you seen other small potatoes, what does the exhaust pipe look like?" ?”

Asking this, Zhao Ming's face turned red, he really hadn't seen it before.

"Xiao Qin, you are very familiar with Little Tudou, please tell everyone what the original exhaust pipe of Little Tudou looks like." Liu Shengli said from the side.

At this time, Liu Shengli was very happy. He introduced Qin Shaoyou, but these people still didn't approve. Now, Qin Shaoyou talked about fault analysis in a clear way, which is to make him look good, but now, he has already made a splash. It is still necessary to ease the atmosphere. After all, Qin Shaoyou will still make extra money here in the future. It is not good to offend Zhao tomorrow.

"The principal of our technical school drives a small potato. A few students broke down and blocked the exhaust pipe for the principal." Qin Shaoyou said: "So, I am very familiar with the exhaust pipe of the small potato."

"Haha." Hearing what Qin Shaoyou said, Luo Yongwang and Liu Shengli both laughed, and the embarrassment was eased in the laughter, and Liu Shengli pointed to the nose of his lover: "Is that you who blocked the exhaust pipe? No, how do you know so clearly?"

No matter what Qin Shaoyou said was a joke or it was true, in short, everyone present had a lot of affection for Qin Shaoyou. Taking advantage of this opportunity, Qin Shaoyou said: "The solution is also very simple. Add some length and take the exhaust to the outside as long as it doesn't interfere with the fan."

"Okay, I'll weld." Apprentice Liu Yongliang volunteered.

"You can't weld on it, it's easy to catch fire, so remove the exhaust pipe." Qin Shaoyou watched Liu Yongliang's movements, and quickly stopped him. Can that thing be welded directly?This engine has gone through many years of ups and downs, and many places are leaking oil. If the electric welding is poked, the entire engine may be ignited by the arc.

Hearing Qin Shaoyou's words, Liu Yongliang stuck out his tongue.
