Chapter 228 Chapter 226 Dismantling an Engine

It’s useless~~ It’s useless.

In the temporary research room of the steel rolling mill, a disassembled engine was placed on the workbench. This engine was too playful. Not to mention the functions of some parts that I couldn't understand, but as soon as I unscrewed them, the parts underneath actually popped open. If you want to put it back together, you have to disassemble other parts, and when you disassemble other parts, you have to assemble it in various confusing ways.

There are so many screw accessories. If one part is loosened, the other parts will be loosened. There is even an electronic self-destruct mode, which is also a physical mode. Sure enough, if the disassembly is not carried out according to the installation sequence, if a part is loose, it will be like a trigger trap. If something like a copper wire is attached, it will bounce onto a small electronic, and then Cause a small short circuit to burn an accessory.

Anyway, the people in the research laboratory can't assemble it now. This engine was provided by Director Zhao of the automobile factory, and it is an engine that has been tested for operating performance. It was handed over for them to further test the horsepower and so on.

Tests at automobile manufacturers, through idling, have preliminarily proved that fuel consumption is definitely much lower than before. Moreover, the rotation speed is fast and the vibration amplitude is very small.

Moreover, the car factory has installed an engine on the Jeep, and the performance improvement is currently relatively perfect. It’s just that the maximum load capacity of this engine has not been tested yet, and a lot of data needs to be tested slowly. Luo Cheng has a theoretical test of the engine, but the theoretical test can only be a basis. Everyone engaged in research and development understands the gap between theoretical data and actual data.

For example, in a country that pursues quality the most, their standards are calculated based on the lowest installed load. For example, if the truck load limit in Japan is ten tons, maybe these ten tons are safety standards, and you can actually pull twenty tons without any problem.

If the domestic load capacity of ten tons is considered overloaded, it is definitely a high load. If you pull more cargo, there will be problems.

The problem now is that everyone is testing the theoretical data provided by Luo Cheng and under what circumstances it is the standard obtained. Before disassembly, the maximum load horsepower of this engine was tested using traditional mechanical torque. It has already exceeded the theoretical data given by Luo Cheng. However, if the engine is kept running under load, damage will indeed occur.

This is just like driving with the accelerator pressed all the way. The engine, as the heart of the car, can't survive.

"What should I do with this engine? It seems like it won't go back yet."

"Go and tell Director Zhao that this engine is used by the above. Treat it as a normal purchase from them. By the way, Luo Cheng has set a price for this engine."

"Yes, it costs 3,000 yuan each. It is not for sale at the moment."

"Three thousand, it's so expensive, you dare to buy an imported engine."

"The price seems to be set for export. According to their intention, even if you pay 3,000 people, they still won't be willing to sell it. We all know that it will cost a lot of money to add just one car engine production line. Luo Cheng The automobile factory here developed and produced it independently because the engine was stuck. But no one expected that Luo Cheng was so capable and could get the engine out in such a short time."

"Three thousand is just three thousand. Anyway, the meat will rot in the pot. Spending more RMB is better than spending foreign exchange. And this engine is much better than the imported one, so we will send it to Sijiucheng and Tianhu at this price. There are many foreign businessmen over there, and if they like it, we can export it at this price. If we can’t afford the price, we will use it ourselves.”

"Then do you want to bring another one over for disassembly testing?"

This question~~Although the meat is rotten in the pot, it is still meat. You can't overcook a piece of meat until nothing happens, and then take another piece of meat and cook it blindly.

I have recorded the disassembly method on several sheets of paper. When I first started to dismantle the problem, I said that I couldn’t figure out how to restore it unless I dismantled the lower part. However, I dismantled the lower part and found that I didn’t understand the assembly structure of the lower part and could not restore the upper assembly structure. This is One set after another, almost to the end of the disassembly, I found that I still had no clue how to restore and assemble it.

Spend another three thousand to buy one and dismantle it for fun. This is not how the funds of the research laboratory are used. That is, the engine is produced domestically, and the profits earned by the car factory are also handed over to the state. Even if he uses the profits to buy other things, and the other things generate profits in disguised form after receiving the money, they still belong to the country.

If this imported engine were dismantled like this, it would be a pure loss and turn into a pile of scrap metal.

He rejected the proposal to continue dismantling, and instead asked people to bring cash to buy the two remaining engines from the automobile manufacturer. This account cannot be hung on the steel rolling mill. Even if Luo Cheng discovers their trick in the future, he cannot take the initiative to expose it now that Luo Cheng doesn't know about it.

The automobile manufacturer has built a total of five engines. According to Director Zhao, he has used two engines himself. In addition to the modified engine of the jeep that Team Leader Jiang drove, he also had a jeep when he was still a repair shop. Keep the modified ones.

As for the jeeps brought from the military factory, since the shock absorbers and booster pumps have not been modified, there are no plans to modify them immediately. Because the engines were not enough, Director Zhao suggested leaving a few for testing and export demonstrations before leaving the others.

Otherwise, if there is no takeaway, there is really no need for car manufacturers to export engines at present. Therefore, if it is not for external circulation, let alone selling it for 3,000, the price of 5,000 is just a word. Or if you set a cost price of a few hundred and still can’t buy it, what’s the use.

Ngee Ann Automobile Factory.

After get off work yesterday afternoon, Luo Cheng checked in at the farmer's market again.

The things I got were pretty good, including one pound of frogs, two pounds of preserved eggs, three cucumbers, one pound of dried kelp, and two pounds of water spinach.

Frogs are no longer allowed to be caught in the wild in future generations. But in fact, if you try to catch them, you won’t be able to catch them. They are basically farmed. But in this era, there are many bugs and frogs in the fields in spring, which is not a good thing. But Luo Cheng loves to eat this. The system signed in, at least there is no virus.

Preserved eggs are also known as preserved eggs. Those who love this flavor will like it very much, but those who don’t will not be able to accept the taste. As for water spinach, it is also an out-of-season dish during this season. Cucumbers are given according to the number of roots. This system is not serious. Why not count them by the kilogram? Use the word "root" to tease girls.

As for kelp, it is considered a good thing in this era, and most people cannot eat it.

Today's meeting ended quickly. The main focus was to put the production of engines on the agenda. The current strategy for spare parts is to produce them internally and also find other factories to cooperate with them. For some difficult parts, if one machine is not enough, the car factory will get an extra machine to follow the production. If one machine is not enough, it will use two machines.

After all, not every part of automobile parts is equally easy to produce. To synchronize the production of parts, it is naturally necessary to adjust the number of machines. Now even if the car factory sells all the cars, there will not be much profit left, and the engine is not of much use at the moment, and the purchase quantity of the transmission is stuck.

Luo Cheng asked Director Zhang to contact the motorcycle factory in the neighboring city. The single-set transmission of motorcycles can be assembled on a three-wheeled truck. However, for the convenience of reversing, you can assemble two sets of single transmissions just like today's cars. If you don't want to use a dual clutch, then use dual levers to operate separately. One controls forward and one controls backward.

But Luo Cheng didn't want to purchase transmissions from motorcycle factories for a long time. Single transmissions were too unsuitable for automobile factories. Luo Cheng plans to make his own transmission, and the production equipment can produce single transmissions by the way. Therefore, if we produce it independently in the future, we will no longer need to purchase transmissions from motorcycle factories.

After the meeting, Luo Cheng had to take people to assemble the motorized forklift again. It's not difficult to assemble this forklift, but it's just not fast. One thing weighs dozens or hundreds of kilograms at a time. Unlike the three-wheeled trucks and cube trucks that were assembled before, without the help of mechanical assembly, even if they know how to assemble, it will take several people to assist.

It's also necessary to tighten a few screws. If the thing is small, one person can just put it in the opposite port and tighten it. But heavy items require several people to carry them.

One day, plus the time wasted yesterday, only turned into a semi-finished product. The chassis and truck were all installed. However, the console and body have not been installed yet. Luo Cheng designed the body this time to look like later generations, with iron plates and glass.

This time it has to be installed with glass, it is for export, it shouldn’t be too shabby. But Luo Cheng in his factory plans to keep a spare one first, which does not require the installation of glass. Even if it is sold domestically in the future, he does not plan to install glass. It only needs a frame and a green leather rain cover as a spare.

It can provide protection from the sun when it's hot, and it can protect you from the rain when it rains. When the weather is nice, the rain cover can be folded up. Of course, Luo Cheng wants to give priority to export, and has already negotiated with the steel rolling mill. The forklift will be used to try to export first. If it fails, it will be sold domestically. But if it is sold domestically, Luo Cheng does not have to think about how to sell it. The steel rolling mill Anyway, it's all round. There are only two prices for export and domestic sales. In addition to the shape of the mobile forklift, which is not as labor-intensive as the car, the other costs are not worse than the car at all. Moreover, foreign forklifts are inherently more expensive than cars. They are special vehicles and are generally manufactured by heavy machinery factories.

In the afternoon, Team Leader Jiang and the others told Luo Cheng that they were going back to Tianhu. They had already bought their train tickets and would only leave in a day or two. When designing gearboxes, as long as there are drawings and requirements, the equipment moved from the previous military factory can be produced. There is no need for Team Leader Jiang and the others to keep helping.

But judging from the currently disassembled transmission, it seems that the form of the gears is different from that of later generations of automobile gears. The thickness of the gear is wrong. If the material is poor, it will be easily worn out once the rotation speed reaches a certain critical value. The number of gears of the variable speed variable device is not only related to the engine, but also related to its own quality.

Cars in this era basically had to shift into a gear for around 15 yards. For cars in later generations, it was basically a gear for 20 yards. Even better cars, it was normal to shift into a gear for 30 yards. But the current variable speed can only be used for speeds up to a hundred yards. If it is too high, it cannot be raised. If you step on the accelerator, it will cause subsequent problems due to excessive heat.

To be precise, even if the transmission is not stuck due to the purchase quantity, the current transmission is not worthy of the newly produced engine. The engine is the heart, and the transmission is the limbs. If you have short arms and short legs, it will be of no use if your heart is strong and healthy. If you want to hit someone, you have to jump up and hit them.

When he got off work, Luo Cheng went to the farmer's market again and started researching and developing the transmission tomorrow. Although the transmission was not as complicated as the engine, it would take several days to obtain the complete drawings.

"System sign in."

"Sign in successfully and get items. One pigeon, two pounds of amaranth, one pound of peanuts, two pounds of carrots, and one pound of braised beef."

This kind of braised beef is definitely not available in farmers' markets in this era, and even if there is one that sells braised beef, it is not sold here. In later generations, cooked food was sold in some markets, and the same was true for pigeons. Meat pigeon varieties had not been introduced in China at this time, and pigeons rarely entered the market even if they ate meat.

In addition to signing in, Luo Cheng also bought some bones and meat from the market. After being shameless, he bought it for 20 cents per catty. Generally speaking, there are ways to buy meat and bones without paying a ticket. After the hospital provides proof of fracture or injury to the bones, you can buy the bones in the market for 15 cents and take them back to stew in soup.

Luo Cheng got some bones and got the dried kelp out of the system. When Xiaoyu and the others returned home, Luo Cheng handed the bones to Bingzi and sawed them in half. The marrow inside the bones could not be wasted. The main reason is that I don’t have a pressure cooker, otherwise it will be stewed without sawing.

Xiaoyu and the others have never eaten kelp before. Even if they have seen it, they only saw it in the market after coming to the city. You have to buy a ticket, kelp is also considered seafood in this era.

Shishi was curious and asked what kind of kelp was in the sea. Luo Cheng told her that it was a vegetable in the sea, or it could be regarded as seaweed. But they are nutritious. In fact, many vegetables were originally just grasses. Many wild vegetables today, for example, are also grasses if you don’t know them.

Kelp bone soup, especially the kind with sawed bones, is still very tasty even if it is not stewed in a pressure cooker. When you eat kelp for the first time, you will feel a toughness. In fact, kelp is a plant with a good taste. It's good for stewing or cold dishes with some seasoning.

There is still a full bowl left to take back home. My father will deliver it again tomorrow. Even if the father doesn't come, as long as someone from a large group comes, he can be helped to take him back.

At night, the content of Water Margin has been seen on Liangshan, and the plots of Liang Shanbo and Zhu Yingtai can be seamlessly connected.

The next day, when Luo Cheng came to the factory, he still held a meeting first. Luo Cheng was currently in charge of the assembly of the forklift and there was no need to mention it again. The next step is for Luo Cheng to announce the development of his own transmission box. Although the performance of the dual-clutch transmission is more stable, it increases the difficulty of driving. As a manufacturer of cars, it is the driver who is served.

Team Leader Jiang and the other two are going back to Tianhu. Luo Cheng is responsible for research and development, and Director Zhao is responsible for cooperation.

Of course, the more important task now is that a lot of square cars and three-wheeled trains have been produced. The apprentice workers are also touching up the paint. Although the paint was applied at the beginning, many connections at the back are welded and need to be polished and repainted.

The vehicles produced now are displayed in the new venue, which is very spectacular. The car purchase vouchers can be issued in advance and given to local units, and they still have time to distribute them.

As for the additional planned output, if it matters, we can work together to find ways to benefit the factory. There are really people who have something to do with this proposal. Although Director Zhao is an outsider, the monks from outside are just as good at ringing bells. Director Zhao can get high-end tobacco and alcohol, but this is not a benefit for employees, but it is suitable. The factory is used for entertainment and welfare for leaders.

Smoking and drinking are also good, you can try it. But Director Zhang said that the textile factory needed three-wheeled trucks and the transaction could continue as usual. Director Zhao and Section Chief Liu who came later did not understand what he said.

Director Zhang has no scruples. Isn’t this what all manufacturing companies do? Benefits are exchanged. Otherwise, why would everyone be working hard to produce beyond the task? But Section Chief Liu came from a local unit and had never seen this secret operation at all. But think about it, if big factories don’t have such operations, why should enterprises have better welfare than local units? All profits are handed over. Relying on self-retained funds is just money. In this era, money cannot buy without the cooperation of bills. what.

Anyway, based on this calculation, this year’s New Year already has meat and cloth, including tobacco and alcohol. Ordinary employees can apply to purchase it if they are official. In this era, there are also employees who like to store good wine. If there are many, it is no problem to take care of them.

There is actually a lot of demand for three-wheeled trucks at the grain station. Even if the grain station in Ngee Ann has enough trucks, the counties below also need them. If the food gap can be solved, some soybean oil can be obtained at the grain station to provide welfare. .

The factory is still purchasing eggs now, and eggs are definitely a bonus to be distributed during the Chinese New Year. But the issue is how to distribute. As for some small things, such as matches, soap, etc., we are not talking about it.

Director Zhang is going to Hongcheng today and will drive there by himself. He will try his best to get small things, even if it is a towel or a candle. There is a shortage of everything these days, so anything can be used as a benefit, but you can't just use small things as a benefit.
