Chapter 252 Counting Patterns

Chapter 169: Counting Patterns

"I'll show you a simple inspection process. How much you can learn is your luck." Song Guoyuan walked to the front of the car, and then waved his hand to signal Liu Liang to turn on the high beam and low beam.

Song Guoyuan gave a lecture in person, and Wang Hu and others excitedly lined up beside Song Guoyuan, standing upright as if they were sandwiched between them to welcome the leader.

Liu Liang opened the driver's door and sat inside. After turning on the power, two fan-shaped lights shot out.

The most critical moment finally came. Wang Hu and others focused their fiery eyes on Song Guoyuan, carefully observed his every behavior, and were always ready to figure out the meaning of every subtle movement of him, striving to learn the true skills .

But under the watchful eyes of everyone, Song Guoyuan turned his head from side to side and looked around quickly and found nothing unusual, and said to everyone: "Okay, there is no problem."

Immediately afterwards, Song Guoyuan signaled Liu Liang to turn off the headlights again and asked him to turn on the wipers.

As the wipers began to dance on the dry front gear, Wang Hu and others' fragile hearts were as messy as the creaking noise.

The scrutiny that everyone was looking forward to, the long-winded and serious explanation, the incomparably detailed comparison introduction, etc. did not appear at all, but Song Guoyuan only took a few seconds and said "OK, no problem" to end the inspection of the headlights. , which they did not expect.

Depressed, confused, puzzled, all kinds of emotions were churning in everyone's minds, and they were revealed through astonished expressions.

Song Guoyuan glanced at Wang Hu and the others who were in a daze, then smiled slightly and looked at Fang Yuan.

Song Guoyuan didn't mean to explain anything. Fang Yuan felt sorry for his colleagues. He coughed twice and dragged everyone's souls back. different."

"When appraising the condition of a car, it is necessary to consider whether the headlights have been changed or replaced, and compare the newness and oldness of the lights on both sides. From these aspects, it can be judged whether there has been an accident, and it can even be used as a basis for judging the age of the car."

"And you don't need to think about these when you do the inspection before the trip. You just need to check whether the headlights are working normally. They are all faultless. Of course, there is no need to continue the inspection." Fang Yuan bowed his head and pointed at the headlights. Group, "Oh, by the way, at most the headlights of some SUVs are not bright enough, and then decide whether to add off-road lights or something."

"Oh, I'm going."

"It's that simple?"

Wang Hu and the others looked at each other, and they were all dumbfounded. They really didn't expect that the inspection process they were looking forward to so much was so simple.

But they are very clear now, because Fang Yuan explained it very clearly: it's just an inspection, and it's not a car dealer to collect the car, so why make it so complicated?
Song Guoyuan still didn't say much, he looked at Fang Yuan with a smile in his eyes, as if he was very satisfied with Fang Yuan's performance at this time.

Fang Yuan had already checked the condition of the Audi A4allroad with his basic second-hand car identification skills, and knew that there was no problem with his car, so Song Guoyuan checked the wiper, front and rear gears, and all the door glass very quickly, as if he just glanced at it. After finishing all the procedures, it is not as laborious as when Sun Yanming checked the glass, looking at the chassis number on the front windshield and the production date on all the glass.

Wang Hu and the others were not stupid. After Fang Yuan told them the difference between the vehicle condition appraisal and the pre-travel inspection, he immediately understood that Song Guoyuan ignored all the details, and there was no need to do these inspections.

Song Guoyuan didn't check the paint surface of the car body and the A, B, C, D pillars, etc. Under the gaze of everyone, he stood on the right front wheel, then stepped on the tire wall with his foot, and muttered softly: "The tire pressure is a bit low."

Fang Yuan's primary used car identification skills did not have any results on tire pressure, but he still knew some knowledge about tires.

Some models currently produced can accurately display the real-time tire pressure of the four tires on the instrument, and some are only equipped with a tire pressure alarm, which will not display the specific tire pressure value. When the tire pressure is low, it will send a reminder to supervise The owner inflates.

As for those models without tire pressure monitoring and tire pressure alarm, it is a bit troublesome.

Either step on the tire wall like Song Guoyuan, or buy a tire pressure gauge and install it yourself.

The method of stepping on the tire wall is impossible for an experienced driver. Fang Yuan thinks it is more reliable to buy a tire pressure gauge. After all, it is only a few dozen yuan and it is very economical.

The tire pressure gauges installed by ourselves include external ones, built-in ones, and some connected to the car, and the built-in ones need to be dynamically balanced, while the external ones do not need to be done.

"When you check the car, you must check it carefully." Sun Yanming even squatted next to the tire, pointed to the pattern on it, and signaled everyone to look here.

"Huh?" Song Guoyuan just finished explaining the headlights, wipers and car glass with a simple sentence. The abnormal reaction now makes everyone very curious.

Fang Yuan saw everyone's doubts, and explained for Song Guoyuan: "The headlights, wipers, and car glass are broken, which will affect driving at most, and tire failures will kill people. Cars often lose control on expressways. The worst tragedy is that there is a problem with the tires."

"Oh, so it is." Wang Hu and the others looked indifferent just now, but immediately became dignified, and looked at Song Guoyuan seriously, looking forward to what he would say next.

"Yes, what Fang Yuan said is very correct. Tires are indeed very important. More than 90.00% of car blowouts are caused by lack of air. Others include punctures and aging tires. However, blowouts caused by overinflation are relatively rare. , There are many ways to check tire pressure..." Song Guoyuan recounted some of the knowledge Fang Yuan recalled just now, and then said, "If your car does not have tire pressure checks, no tire pressure alarms, and you have not installed a tire pressure gauge , When the tires break down halfway and need to check the tire pressure, let me teach you a simple way to count the tire treads.”

"Count tire patterns?" Wang Hu and others approached Song Guoyuan, and even Fang Yuan stood behind Song Guoyuan curiously, looking at his finger.

"Counting the tire pattern is a rough detection method." Song Guoyuan inserted his finger into the groove on the tire, "The rubber bump next to it is the tire pattern. Under normal circumstances, the contact between the pattern and the ground is limited. The number should be six, if there are more than eight patterns, it means that the tire pressure is already low, and if it is less than five, it means that the tire pressure is high."

Liu Liang squatted beside Song Guoyuan, pointed to the pattern on the side of the tire wall and began to count: "1, 2, 3... seven, which means the tire pressure is a bit low."

"Yes, if you find that the tire pressure has become low, you can also count the tire treads as a standard when you use the air pump to inflate. When six tire treads touch the ground, it is almost the standard tire pressure."

"But the tire patterns are not all the same." Liu Liang raised his own doubts. He wanted to know what to do if the tires were changed.

"As I said just now, counting tire treads is a rough detection method." It's a matter of human life, even the eccentric Song Guoyuan didn't get angry with Liu Liang, "You can pay attention to the number of tire treads touching the ground when the tire pressure is standard. , as your own standard."

　Because I went to the hospital today, the update is late.
