Rebirth of the Auto Giant

Chapter 287 Helping

"Okay, remember this lesson. Remember it in the future and don't reveal your identity at every turn." Duan Luanhong finished speaking and walked over.

The two came to the front and looked down. A strong smell of burning plastic came from under the engine.

"Master, did you check the water tank when you got up early in the morning?" Guo Yuquan asked.

"After checking, I still know this common sense. I have been driving for more than ten years, and I deliberately added a full tank of water when I started the car." After the driver finished speaking, he looked at Guo Yuquan and asked: "Why?

Already?"

"It looks like the boiler is boiling and the engine is overheating," Guo Yuquan said.

"No, the engine is overheated, so how can there be a smell of burning plastic? Isn't it a circuit short circuit?" the driver said.

"Is it true? It needs to be checked. Let's start it again and have a look." Duan Luanhong said.

The driver also knew that Duan Luanhong was his senior brother, and what he said was more effective than Guo Yuquan. After hearing Duan Luanhong's words, the driver nodded and returned to the driving position, transferred the key, and the engine started beeping.

"It's normal." Guo Yuquan muttered when he saw that the engine was operating normally and looked at Duan Luanhong.

"Stopped." Duan Luanhong said, "The engine is normal. Why did you stop the car just now?" Duan Luanhong said.

"I just smelled a burning smell. I stopped the car and turned on the engine. I saw smoke coming out like tangerine sticks burning in the countryside. Do I dare to drive? If I don't find out the cause and continue to drive, the engine will pull the cylinder.

What should I do? The company still won’t punish me?” the driver said.

The driver looked at Duan Luanhong and asked: "Master, do you see where the problem is? Please help us. We don't dare to go forward now. This bus only comes in a few hours. Isn't it a waste of your time?"

"You did the right thing. If you find something wrong with the engine, you can't go any further. You have to stop and check. Otherwise, it may cause a major accident involving engine cylinder failure. Engine overhaul is very expensive," Guo Yuquan said.

"Thank you two masters for your compliments," the driver said.

"Fortunately, it seems that the engine is still normal now. The fault should be outside, not inside the engine or the circuit." After Duan Luanhong finished speaking, he pointed to the small plastic tube on the water tank cover and said: "Look

By then, the water in the water tank has boiled, and the boiling water continues to flow out, indicating that the engine is overheated. If you drive further, the engine will most likely pull the cylinder." Guo Yuquan said.

ah?

The driver was shocked when he heard this.

What a risk!

"My junior brother is right. The water temperature gauge of this old car is also broken. We can't know the engine water temperature in time. If it weren't for the smell of burnt plastic, if we keep going, the engine will be pulled sooner or later."

Duan Luanhong looked at the dashboard and found that there was no sign of a water temperature gauge.

"Then what should we do now? Please help me, two masters, and I will pay you two wages to the company when I get back," the driver said.

Duan Luanhong did not answer but looked at his junior brother Guo Yuquan and asked: "Junior brother, what usually causes the engine water temperature to overheat?"

"Brother, you are testing me. It's very simple. There is a problem with the cooling system. The most common problems are the thermostat and the fan belt. These two are most likely to occur and are also the most likely causes of excessive water temperature.

."

"The thermostat is the component that determines whether the engine cooling water takes a large circulation or a small circulation."

"When the engine just starts running, in order to allow the engine to reach normal operating temperature as quickly as possible, the coolant only circulates in the engine through the water pump, which is called a small circulation."

"When the water in the engine water channel continues to rise due to the heating of the body and cylinder head, the water temperature reaches the opening temperature of the thermostat (usually after the temperature is 80°C) the thermostat will open, and the high-temperature cooling water will pass through the heat dissipation

It cools down the engine and then returns to the inside of the engine. It cools down the overheated engine to keep the engine operating temperature within the ideal temperature range."

"If the thermostat is stuck in the closed position due to various aging problems, the cooling water will continue to circulate in a small circle without being cooled by the radiator, and the engine water temperature will continue to rise until it boils, that is, the boiler is opened, which will cause the cylinder to

The sleeves and piston rings expand and become soft under high temperature, and the final result is cylinder pull."

When the driver heard Guo Yuquan's words, he couldn't help but look at him for many years.

As expected, he is from a big company. It seems that at such a young age, this theory is right and I cannot accept it.

"Inspect according to the rules from outside to inside. First check the belt, then look at the thermostat." If there is a problem with the thermostat, just remove it and run the full cycle. This will have no effect on the engine.

After hearing this, Guo Yuquan pressed down on the triangle belt hard, and his fingers collapsed about ten centimeters. "Brother!" Guo Yuquan looked at Duan Luanhong and said.

Duan Luanhong pressed it and said, "The normal tension will not be so small. It should be due to insufficient tension caused by the aging of the belt, which results in insufficient speed of the water pump. Loosen the belt adjustment screw and take off the belt to take a look." Duan Luanhong

He pointed to a series of triangle belt adjustment screws and said.

"I'll do it!" After the driver said, he took out the opening wrench on his car, loosened the belt adjustment screw, and took off the triangle belt.

When the three of them took a look, they found that the V-belt had many cracks, one of which had a very big crack and almost broke.

"Okay, the fault has been found. Master, do you have a new belt on your car?" Guo Yuquan said.

"I'll go look for it in the back. I seem to have seen one before. I don't know if it fits." The fault was found and the driver was also happy. He went to the place where the tool box was on the left and found a V-belt. He walked nervously in front of the two of them.

: "Two masters, do you think this is okay?"

Comparing the two, the size is right.

The driver put on the belt and adjusted the belt tension under the guidance of the two men. Guo Yu pressed the belt fully and said, "That's it."

On the highway, those customers who got out of their cars to enjoy the cool air on the side of the road heard the car restart, and then heard the salesperson waving and saying: "Let's go! Let's go!"

"Is the car ready?" Everyone stood up, patted their butts and walked towards the car.

The car started off again. Everyone heard the driver's story and knew that the fault could be solved with the help of Duan Luanhong and Guo Yuquan. Everyone couldn't help but give a thumbs up when they heard that the two were maintenance masters from Tang Dynasty Power Company.

"Your transportation company was lucky this time. We met two masters on the bus. I asked you to return the fares of these two masters."

"Yes, if there are not two masters to help, you may not solve the problem by sending people over, and it will also waste all of our time."

Everyone was talking a lot.

"Master, what do you think?" the saleswoman said, looking at the driver.

"Okay, we can't let the two masters help in vain, so we will return the fares to the two masters. This is our company's gratitude to the two masters. We will just tell the company when we get back." The driver said.

Duan Luanhong shied away for a while, but the other party insisted on giving it and accepted it.

"We workers have the power..." I learned another trick today, and also "eavesdropped" on Guo Yuquan's lecture on some theoretical knowledge of the cooling system. The driver happily hummed a song and drove the car forward.
