Chapter 19: The old-fashioned CA10
The history of Shougang can be traced back to the Longyan Iron Ore Company during the Republic of China.
In December 1964, China's first 30-ton oxygen top-blown converter was built. It was the first steel company in China to adopt blast furnace coal injection technology.
In 1978, steel output reached 1.79 million tons, making it one of the top ten steel companies in the country.
It can be said that Capital Steel Plant is definitely a key enterprise in this era, and all kinds of benefits are very good.
In their parking lot, you can see many Jiefang trucks produced by FAW, as well as some BJ130 light trucks produced by the Capital Second Automobile Manufacturing Plant.
What Jiang Hui needs to repair today is a CA10 Jiefang truck.
This product will definitely be outdated in later generations, but it is the main model in the Chinese transportation market in this era.
FAW’s first-generation product is the Jiefang CA10, which is a replica of the Polar Bear Geese 150 car.
In the early 1960s, the Jiefang CA10 car made some technical improvements, and the model was designated as the CA10B truck.
The output at that time reached the design level, with an average production rate of one vehicle every five minutes, and the annual output accounted for 80% of the national vehicle production.
Jiang Hui did not expect that such a common truck could not find anyone to repair it.
It seems that the car repair skills of people in this era are really average.
"The engine of this car has been unable to start normally. Please confirm it first and make sure you are confident that it can be repaired before starting."
"If you are not confident, forget it."
Just as Jiang Hui circled CA10, Li Jianfeng felt that the other party was pretending and his tone of voice was not so friendly.
These days, any car is valuable.
If the car is not repaired but gets worse and worse, that is a big problem.
In this era, when enterprises and institutions purchase cars, they need to be evaluated based on the company's level, output value, profits, fixed assets, etc.
When relevant units need to purchase a car, they must first apply to the competent department, and only after review and approval according to national regulations can they be allocated planned indicators.
Then the State Administration of Materials issues a vehicle supply certificate, and the enterprise purchases the vehicle with the certificate.
It can be said that the contradiction between supply and demand of automobiles has always been prominent.
“Most of the Jiefang trucks on the road now are CA10B type. The CA10 type like this twenty years ago is a relatively rare model.”
“But its I am confident that all problems can be solved.”
At this time, Jiang Hui will definitely show off his skills appropriately.
Otherwise, even if you come here, you will be driven away without earning 100 yuan, which would be too uneconomical.
“How do you know this is a CA10 and not a CA10B?”
Li Jianfeng naturally knew what model the faulty vehicle in front of him was, but Jiang Hui could see it at a glance. A little more expectation.
Maybe this young man can really be fixed?
“The characteristic of Jiefang CA10B is that the windows in the driver’s and co-pilot’s directions are equipped with hinges, and both windshields can be pushed open for ventilation.”
"On Jiefang CA10, only the driver's side window is equipped with hinges."
Most people definitely don't know this kind of detail, but who is Jiang Hui?
“The logo of the Jiefang CA10B is stamped directly on the water tank cover, which simplifies the pattern on the water tank cover of the Jiefang CA10 and cancels the red round logo.”
“However, The front face grid of Jiefang CA10B is the same as that of Jiefang CA10, which is 9 lines and 18 grids. Sometimes it is really easy for people to get confused.”
A simple common sense answer made Li Jianfeng think a lot more about Jiang Hui. confidence.
As for Chen Chenxing next to him, he was holding a notebook and quickly recorded what Jiang Hui said. These things cannot be easily seen by reading a book.
"The toolbox for repairing the car is placed under the front of the car. You should study it first. I am in the office next to it. If you need anything, come to me anytime."
Confirm Li Jianfeng felt relieved now that Jiang Hui was not here to make soy sauce.
Otherwise, even if Chen Chenxing's father recommended it, he would not dare to let Jiang Hui dismantle the car casually.
When Li Jianfeng walked away, Chen Chenxing immediately came over and said, "Master, the engine of this car cannot start normally. People from Shougang have been tinkering with it for more than a week, but it still hasn't been fixed."
"If If it doesn't work, they will have to ask people from FAW to repair it. "
"But this process is more troublesome, takes a long time, and will definitely cost a lot of money in the end."< br>
“So after my dad communicated with the people in the logistics department, they agreed to let us come over and give it a try.”
Although the people at Shougang couldn’t repair this CA10, they must know that FAW People can be repaired.
It's just that Shougang is definitely not willing to do this kind of asking for help unless it is absolutely necessary.
“This kind of engine can be started, but it is very difficult to start and cannot run continuously after starting. Nine times out of ten, it is a problem with the carburetor.”
Jiang Huizi From the driver's seat, I tried to start the CA10.
I tried several times in a row, but it either failed or stalled after a few seconds of success.
In this case, he can basically determine that it is a carburetor problem.
Jiefang CA10B uses FA-231-A2 carburetor to replace the MKZ-K-80 carburetor on Jiefang CA10.
People from Shougang are probably familiar with CA10B, but they don’t know much about the old carburetor on CA10.
If you have a brand new carburetor, just replace it and it will basically solve the problem.
Of course, replacing parts at every turn is a common car repair method in later generations of 4S shops.
In this era of car repairs, it is possible to replace parts without replacing them.
Three years of new life, three years of old life, and another three years of mending.
This attitude towards clothes is similar to the attitude of people in this era towards various auto parts.
“I know that the carburetor is an important component of the engine. Its function is to atomize the fuel and evenly mix it with the air to obtain a certain proportion of combustible mixed gas so that the mixed gas can burn well in the cylinder. "
Chen Chenxing obviously read a lot of books during this period. As soon as Jiang Hui talked about carburetors, he memorized some relevant introductions in the textbook.
“You are right, the most common carburetor failure is oil line blockage.”
As Jiang Hui spoke, he opened the engine cover and prepared to teach Chen Chenxing step by step how to disassemble the carburetor.
As a very classic engine in this era, there are models in the laboratory of the Vehicle Engineering Major of Capital Institute of Technology.
In just a few minutes, Jiang Hui successfully removed some parts around the carburetor.
“The carburetor is generally clogged in the following situations: the main oil volume hole, foam pipe and main nozzle are clogged, or the accelerating oil and air passage is clogged.”
“When around the main nozzle When the air seepage hole is blocked by dirt, the air entering through the air star hole oil well cannot penetrate into the main nozzle to form a foam mixture, resulting in poor fuel atomization. ”
"When you step on the accelerator when the engine is under no load, the speed is difficult to increase, the carburetor backfires, and you feel that the power is insufficient while driving, and it is easy to stall and difficult to idle."
"When inspecting, depress the accelerator pedal quickly and continuously, and use The rapid acceleration device replenishes oil into the throat. If the operation is normal and the flameout phenomenon disappears, the main oil supply device is blocked. It can be disassembled and cleaned to clear it. If necessary, replace it with new parts. ”
