Development of productivity started in 1981

Chapter 119 Testing the Engine at Jialing Plant

On July 1982, 7, Wang Jiankun woke up in a room in a guesthouse near Guabang Mountain.

I opened the curtains and found it was another sunny day. In a few days, it will be the dog days of summer and the daytime temperature will be around 35 degrees.

Because the guesthouse was built on the mountainside, there was mountain breeze blowing through it, and it was close to the river, so the river water absorbed a lot of heat. Therefore, it did not feel very hot. We turned on the electric fan in the first half of the night, but had to turn it off in the second half because the temperature was below 25 degrees.

I looked at the time and it was already 7:10. People working the night shift should be getting off work at this time. After opening the curtains, I could see some workers walking out to the main road and lining up.

Last night I heard Director Tang talk about their management methods. Because they used to produce military products, they adopted military management and had drills in the morning and evening. Now they produce motorcycles, so the drill time is shortened, but everyone has to line up and take roll call before leaving work.

Wang Jiankun brushed his teeth and washed his face while listening to the drill sounds outside the window and the whistle of the team leader. At 7:, he put on his accessories and went out.

In the cafeteria of the guesthouse, Wang Jiankun saw Chen Xingdong and his group. The two factory leaders who were at the dinner table last night were also there, one was in charge of logistics and the other was in charge of purchasing. They were introducing breakfast to Chen Xingdong and his group.

Seeing Wang Jiankun coming, the deputy director in charge of logistics quickly said, "Mr. Wang, how was your rest last night? Did the noise of the machines in the factory disturb you?"

"I had a good rest. I fell asleep soon after drinking too much. There was no noise after the window was closed, so it didn't disturb me."

"That's good. Come and try our factory's breakfast. There are Chongqing noodles, wontons, iron cakes, oil tea, glutinous rice balls, glutinous rice cakes, etc. You can try some if you want." The factory director in charge of logistics said, pointing to several kinds of breakfast at the window.

Wang Jiankun took a look and selected Chongqing noodles, iron cake and glutinous rice cake and put them on the plate.

This buffet-style approach is pretty good. You can just take one of whatever you want to eat, and considering that guests want to eat more than one dish, the portion of each dish is relatively small.

Chongqing noodles come with several side dishes and are a little sour, so they are very appetizing. Wang Jiankun ate them up in one gulp.

Then they ate iron cakes and glutinous rice cakes. The iron cake has a special shape. It is actually made of fermented rice flour and steamed. Its shape resembles an ancient iron. Wang Jiankun thought the taste was quite ordinary.

The glutinous rice cake pieces were fried in oil and smelled very fragrant, but Wang Jiankun felt numb after eating them because they contained peppercorns.

The factory director in charge of logistics seemed to be unaffected at all. He took a big bite of glutinous rice cake and chewed it hard, not afraid of the numbing effect of the Sichuan peppercorns at all.

I have read information before that people in Chongqing love spicy food, but Wang Jiankun can accept the spicy taste. The numb taste is too unpleasant, and it is not easy to spit out the taste in his mouth, so he can only use his tongue to push the peppercorns aside and spit them out, and then chew the fragrant fried glutinous rice cake.

Chen Xingdong and several others also smelled the fragrance of the glutinous rice cake, so they all chose it. When they were eating it, their expressions were very interesting. From time to time, their tongues felt numb and they had to drink soy milk to relieve the numbing taste.

Except for the first bite which made Wang Jiankun feel numb because he wasn't paying attention, he had the superpower to break down the numbing molecules of the peppercorns, so the food tasted delicious.

After breakfast, the deputy director in charge of purchasing took them to the factory reception room, where they had a formal meeting.

The reception room of Jialing Factory was actually located in the mountain halfway up the mountain. The deputy factory director who was traveling with us led the way and introduced the room.

In previous war years, in order to avoid bombing by enemy planes, many holes were dug in Guabang Mountain, and the production workshops were placed inside the caves to ensure stable production.

After the war years, the production workshops were gradually moved from the caves to the newly built factories in the valley, and then the caves were used as general material warehouses or closed.

However, since last year, the production capacity of motorcycles has expanded greatly, and the factory buildings and warehouses have been in short supply, so the caves had to be used. The larger rooms in the factory were reserved for production workshops and workers' dormitories, and some factory offices began to be moved into the caves one after another.

However, these caves have been renovated, and the ventilation and lighting conditions are much better, so you won’t feel depressed when working in them.

After arriving at the reception room, the people from Xingyao Group sat on one side, and the people from Jialing Factory sat on the other side.

The meeting started with some pleasantries, and then Wang Jiankun distributed information and gave explanations to the people from Jialing Factory.

Seeing the beautifully printed materials, the people at Jialing Factory couldn't help but pay more attention to them. They flipped through the materials in their hands while listening to Wang Jiankun's explanation.

"Hello everyone. This time, Xingyao Power, a subsidiary of Xingyao Group, brought three motorcycle engines to Jialing Factory. Next, I will explain the performance parameters, design ideas and application examples of these three engines. If you don't understand anything, please raise your hand and ask questions. I will try my best to explain it to you."

Next, Wang Jiankun gave a detailed explanation of the three engines and wrote and drew on the blackboard in front for several engineers from the Jialing Factory who raised technical questions.

Wang Jiankun brought three engines this time, the cheapest of which was a replica of the one currently used on the Jialing 50. It was just a little more precise than the one made by the Jialing factory, and its tolerance range was also smaller than that of the one made by the Jialing factory itself. So although they were both two-stroke, its horsepower was 20% greater than theirs, and its fuel consumption was 10% less.

The intermediate performance model is similar in size to the first model and can be adapted for use on Jialing 50 by simply changing some parts. However, this engine is a four-stroke and its combustion chamber is 20% larger than that of a two-stroke.

Therefore, the horsepower is also greater, about 40% greater than the horsepower of the engine produced by Jialing Factory itself. At the same time, because it is a four-stroke, the phenomenon of burning oil is almost eliminated, and the combustion is more complete. The situation of black smoke when the throttle is increased will not occur.

The third model is a bit larger in size and is also a single-cylinder four-stroke engine. Its large size means it can have a larger displacement, so its horsepower is about 80% greater than that of the engine produced by Jialing Factory itself, making it more suitable for manufacturing a larger and heavier motorcycle.

The people at Jialing Factory watched and listened, and paid more attention to the visiting group from Xingyao Group. They were especially grateful when they saw Wang Jiankun's unreserved guidance on the questions raised by their engineers.

We previously cooperated with Honda and spent a lot of foreign exchange, but what we bought was not very advanced technology.

Moreover, the Japanese engineers who came for training were particularly fond of finding trouble and complaining about this and that.

When the technology was being handed over, many pitfalls were left behind. Some of them were clearly just a matter of saying a word, but they refused to explain it clearly, resulting in several months of wasted time in digesting and absorbing the technology.

Some senior employees in the factory were dissatisfied with the cooperation with the Japanese company. When they saw the arrogant Japanese consultants, many of them wanted to beat them to death. Although the transaction was finally completed with some bumps and bumps near the set deadline, they gave up the idea of ​​continuing the cooperation and getting more advanced technology from Japan.

That is why the Jialing Factory disregarded business codes and copied equipment purchased from Japan on a large scale, thereby rapidly expanding the production capacity of key components.

After listening to Wang Jiankun's introduction of the three engines, the people at Jialing Factory were looking forward to the actual engines.

Chen Xingdong took the opportunity to say that he would go on board the ship to transport the engine to the Jialing Factory for them to test.

The engineers who attended the meeting were of course very happy. After Director Tang nodded, they surrounded Wang Jiankun and walked towards the dock.

On the way, Wang Jiankun asked Director Mao the question he had asked last night, which was why the dock was not better and the pallets were locked with iron chains.

"Mr. Wang, you don't know that the water level of the Jialing River varies greatly. This dock can only be used for a few months a year. When there is a flood in the summer, the dock will be flooded. That's why this wooden dock was built and locked with iron chains to prevent it from being washed away by the flood."

"When the flood is over, we will rebuild the collapsed dock and use it for a few months. When the water level drops to the bottom in winter, the dock will be unusable."

"I see. I really don't understand the hydrology of the Jialing River. If we can't use it, how will you transport your goods? Motorcycles are also large items, so the transportation volume should be huge, right?"

"The cargo transported through this terminal only accounts for about 20% of the total cargo volume, and it is not used during floods and winter. We mainly deliver cargo to Chaotianmen Terminal and the railway station."

"Most of the motorcycles are currently sold to the north, because the trains can reach several northern provinces, and the south is shipped by water through Chaotianmen Wharf."

"Oh? Then why not ship more to the south by water? The consumption capacity in the south should be higher, right?"

"We have no problem selling our motorcycles in both the north and south. The main reason why we don't have much supply to the south is that the cargo throughput of Chaotianmen Wharf is average. It is also more troublesome to transport our motorcycles onto ships, and there are few ships that can transport this kind of goods. Therefore, it is more convenient to transport most of them to the north by rail."

Wang Jiankun learned from Director Mao that Chongqing's current transportation problems are still a major constraint on its development. Although it is close to the Yangtze River and Jialing River, this is a mountainous area and the upper reaches of the Yangtze River, so the water level changes significantly with the seasons.

Therefore, the docks are not as large and formal as those in cities below Yichang. Many of the docks here are served by floating ships. The depth of the docks into the river varies in different seasons, resulting in the use of suspended pallets to connect the dock and the land.

This resulted in a sharp drop in the port's throughput, and some large cargoes were difficult to transport.

There are many porters at the dock here, who specialize in helping passengers carry luggage and goods from the dock to the shore, because the pier is not easy to walk on and there are long and steep uphill slopes or steps.

After learning about this situation, Wang Jiankun planned to go to the dock on the Yangtze River after discussing cooperation with Jialing Factory. Perhaps he could think of a good way to at least solve the problem of transporting motorcycle engines.

If everything goes well in the future, we may have to transport 1 to 2 engines here every month, and they can only be transported by water, so the loading and unloading at the port must be done, and it must be done at a low cost.

After arriving at the dock, Wang Jiankun took Director Mao and several engineers up there and moved nine motorcycle engines down, three engines of each model. The others would be moved later after more testing was needed when the cooperation was promising.

The engines were packed in wooden crates and weighed more than 10 kilograms. Director Mao called a few people to help carry the engines to the laboratory of the Motorcycle Research Institute.

The men here are all talented in carrying loads. They can easily walk up the slope to the factory road carrying dozens of kilograms of goods.

After being transported to the testing laboratory of the institute, everyone used hammers to pry open the wooden bars and carefully opened the foam box, and then they saw the shining silver engine.

This appearance immediately attracted the engineers of Jialing Factory because the appearance was so smooth, which was much better than the rough appearance of their own products.

In the eyes of engineers, good-looking products generally have good performance, and this kind of surface finish also requires very high-precision equipment to produce.

Everyone touched the engine while wearing gloves. After they had carefully looked at the three engines over and over again, they started testing under the command of Wang Jiankun.

The first thing of course is the horsepower and fuel consumption test. After setting up the test bench and connecting the lines, the three engines were started one after another.

After three low roars, the three engines started smoothly, and the smoke was very light. Seeing this scene, Director Mao and a group of engineers thought that the three engines were good.

From the sound, we can judge that the manufacturing process is very good, the friction is small, and the sound is low and stable, otherwise there will be abnormal sounds.

They had previously trial-produced engines, but due to lack of experience and low equipment precision, the first few engines made an unpleasant and harsh sound when started. When they were disassembled, they found that many moving parts were severely worn.

When these three engines are running, the exhaust gas is very light, which shows that the combustion chamber and stroke parameters are reasonably designed and the combustion is very complete. This will not only reduce fuel consumption but also increase horsepower accordingly.

As they expected, the horsepower testing instrument showed that the horsepower of these three engines was much better than that of their own engines, just as Wang Jiankun had introduced in the conference room.

After half an hour of testing, Wang Jiankun asked them to stop the engine.

After it cooled down, he opened the toolbox he brought down from the ship, picked up the corresponding tools and disassembled the engine, showing the combustion chamber, cylinder, etc. to Director Mao and others. There were no black spots inside and it was very smooth.

After Director Mao read them, he was very satisfied with the three engines sent by Xingyao Group. The next step was to negotiate the price, delivery quantity, delivery time, etc.

However, the durability test still had to be carried out, so Director Mao arranged for the technicians to move a new engine to the test bench for testing.

The disassembled engine will not be reassembled. Director Mao plans to let representatives from the production department come and take a look, to urge them and let them see the difference.
