Chapter 216: Attending Class ([-])

After getting the answer he wanted, Sun Yanming happily drove the car to Tianhong second-hand car market.

After parking the car, the two of them did not go back to the Zhenghong car dealership, and walked directly to Song Guoyuan's house after entering the gate of the market.

Fang Yuan drank more than a catty of white wine, but he didn't feel particularly uncomfortable. First, he was only in his early twenties, which was the peak moment of his life. Second, the wine he drank was good, and the more expensive the wine, The less side effects after finishing.

The door of Song Guoyuan's house was wide open, and Fang Yuan and Sun Yanming saw Song Guoyuan's accidental BMW M3 moved from the wall to the middle of the yard at a glance.

The BMW M3 was torn apart at the moment, the deformed front bumper, the rotten front bumper, the twisted hood... all kinds of spare parts were spread on the clean floor, and the shirtless Song Guoyuan was bowing his head Busy dismantling spare parts.

It's just after two o'clock in the afternoon, and the scorching sun hangs overhead. Fang Yuan finds it too hot to stand in the shade by the door, but Song Guoyuan doesn't feel it when he squats under the sun?

Fang Yuan walked forward to Song Guoyuan, first raised his head and squinted to look at the sun, and then looked directly at the master in front of him, feeling really speechless, this strange old man is really weird.

Hearing the sound of footsteps, Song Guoyuan turned his head abruptly and found that Fang Yuan and Sun Yanming had quickly stood up, his hands were covered with oil, and he was still holding a sleeve in his right hand.

But before he could speak, Song Guoyuan noticed that Fang Yuan's footsteps were a little fluttering, and he smelled alcohol on him.

Song Guoyuan frowned and said, "Have you been drinking?"

"Master, I have a drink with our regional manager at noon." Fang Yuan was very honest and did not lie.

"Oh, drink with the leader." Song Guoyuan's frown relaxed, "Why are you here now?"

Sun Yanming said with a smile: "Fang Yuan drank and couldn't go back to the car dealership to receive customers, so I came to your place for a walk."

"It's really bad for the influence of drinking and receiving customers." Song Guoyuan grabbed a piece of cotton cloth on the roof of the car and wiped his hands, and greeted the two of them, "It's too hot here, let's go back to the house and talk about it."

"You also know it's hot?" Sun Yanming smiled from ear to ear, pretending to be very depressed and looking up at the sky, "I thought someone was made of ice."

Fang Yuan didn't say anything, but looked down at the BMW M3.
The front wheel of the BMW M3 has been hit crookedly, and the front face is completely destroyed. Standing in this position, you can see that the airbag in the car has also exploded. It is conceivable that the accident was tragic at that time.

Fang Yuan heard from Sun Yanming that it seemed that the accident happened to the car driven by his teacher's mother. Even if he had 1 curiosity in his heart, he didn't dare to recall Song Guoyuan's painful memories. Besides, he didn't know how to maintain cars. Just asked softly: "Even the engine is running from front to back, so it's not easy to repair?"

Sun Yanming didn't take it seriously, and told Fang Yuan, "Don't worry, it's nothing in your master's hands."

"It's easy to repair, but this engine is quite expensive." Song Guoyuan stood beside Fang Yuan, looking down at the engine compartment with a depressed expression on his face.

方远知道面前的这辆宝马M3是2011款M3双门碳纤顶版，发动机代号S65 B40，最大功率为420马力，最大扭矩400牛米，是最后一代V8自然吸气发动机的宝马M3。

Fang Yuan doesn't know how expensive this engine is, but he knows that this engine has 8 throttle valves, and cleaning is more expensive than changing oil.

"What's so good about BMW's engine burning and leaking oil?" Sun Yanming really didn't understand Song Guoyuan's idea of ​​repairing this car. "It's better to buy another car than to spend so much money on repairing the car."

Song Guoyuan took a blind look at Sun Yanming and ignored him, instead he asked Fang Yuan: "Which BMW engines burn oil?"

"Well, N46, N52..." This is to test myself. Fang Yuan is a person with a car dealer system. After thinking about it for a while, he remembered several models that burn oil.

N46 and N52 engines are used in many of BMW's best-selling models. The main problem with their oil burning is the valve oil seal. In serious cases, it will cause carbon deposits, problems with the emission system, and even cylinder problems, especially those with long service life and long mileage. The problems of most old BMWs are so serious that they cannot be repaired repeatedly. The owners drive and repair them at the same time, without a calm heart, they will be driven mad by tossing.

"The answer is right, the common problem is very accurate, and the basic skills are very solid." Song Guoyuan's eyes lit up, he was very satisfied with his apprentice, and added to him seriously, "In addition to the engines you mentioned, BMW also has a There is one engine to watch out for, and that is BMW's N14B16 engine."

BMW's N14B16 engine is a 1.6L inline four-cylinder turbocharged engine jointly developed by Peugeot-Citroen Group and BMW, which is used in C4L and MINI COOPER S and other models.

In addition to burning oil, this engine also cannot start the car in the morning. After driving the car hard, you will find that the idle speed is unstable. This is mainly due to the failure of the high-pressure oil pump.

Its water pump is leaking and antifreeze is leaking, its timing chain is prone to failure, causing abnormal rattling noises when the engine is started, and a thermostat failure that causes the fan to work on its own when the car is cold, and it runs for a long time nonstop.

……

"Let me tell you, don't care about N46, N52 or N14B16 engines, it's not a problem." Speaking of engines, Sun Yanming thought of the 1.6L naturally aspirated engines on the old Cruze and Yinglang in the previous car dealership.

Sun Yanming told the two that at that time he had just become the store manager of Zhenghong Motors. Because of his lack of experience, he bought several old Cruzes and Hideo because of his lack of experience. way back.

Thinking of the painful experience at that time, Sun Yanming's heart trembles now.

Because the power of the LDE1.6L naturally aspirated engine is meat, giant meat, and thief meat. When overtaking, I kicked the accelerator pedal into the engine compartment, and still yelled.

Fang Yuan nodded, he understood that being unable to overtake quickly was really dangerous, and at this moment, the benefits of zero-hundred-speed acceleration appeared.

"It doesn't matter if the power is weak, and the 1.6-liter naturally aspirated engine of the Cruze has all sorts of strange failures, and it is very troublesome to deal with. It is like Sherlock Holmes investigating the case, which requires divergent thinking and reasoning from various directions." Sun Yanming sighed and told Fang Yuan, BMW N46 , N52 oil burning and oil leakage problems are indeed annoying, but the problems are concentrated, and those faults are repeated over and over again.

As long as the engine oil is burning, don’t think about anything, that is, there is a problem with the valve oil seal. It is convenient for the car owner and the repairman to find the problem.

What about this LDE1.6 self-priming engine?

It has a lot of faults and problems, and it is also afraid that the owner will spend less money, and the maintenance master is too busy, and there will be problems with different models.

For example, its fuel injection pulse width was found to be too high this time, and if this fault reappears after it is repaired, it may be too low.

For example, its fuel injection and nerve-like, sometimes too lean, sometimes too rich, so that the mechanic lost his mind.

In short, this engine gave Sun Yanming the feeling that it is not uncommon for all kinds of strange faults to occur. Later, Sun Yanming also learned to be smart, and when he knew it could not be repaired, he simply replaced the engine and sold it at a loss.

"You will become a store manager in the future. When collecting cars, you must be careful about some important models." Sun Yanming warned Fang Yuan with a face of resentment, "Don't care how cheap it is, you must not accept it."

"You are a bit exaggerated." Seeing Sun Yanming gritted his teeth, Song Guoyuan smiled, and Fang Yuan said, "The problems that Lao Sun mentioned only happened to the 1.6L naturally aspirated engine, and the late 1.6T turbocharged engine is There are not so many problems."

　After I asked for an assist yesterday, many friends gave me support. I can see it clearly in the author's background, thank you everyone,
