Chapter 93 Marine Diesel Engines

Two weeks later, the experimental 190 diesel engine was moved off the production line.Uploaded by a friend==

The 190-litre, 500-horsepower diesel is quite a big guy, and it will take professional handling gear to lift it off.Put it outside, it's like a prefabricated house.

Compared with the diesel engines previously produced by Jinan Power Engine Factory, the 190 series has made considerable progress in terms of power and energy consumption.Of course, it still has a lot of room for improvement. In the next year or even 30 years, the improved d-type and improved h-type of the 190 series will still be sold. Liu Qiu, as a master, is this 190 diesel engine.

In Sioux City's memory, after PetroChina reinvested in Jinan Engine Factory, they tried several new products, but the Jedi counterattack was still the 190 diesel engine.Due to its reliable performance, it once put foreign diesel engine brands on Liangshan, and in the end it could only survive by bundling sales.

As far as product design is concerned, Liu Qiu's 190 series diesel engine is a masterpiece. The average effective pressure, power, speed, maximum burst pressure, cylinder-bore-stroke ratio, part-load minimum fuel consumption rate, and other indicators are all better than similar products. Once the level has improved, the most rare thing is that he also took into account the need for future improvement, and spent a lot of energy to make a reserved space.This is the fundamental reason why the 190 series has been able to sell well and improve for 30 years.

Although Liu Qiu's future works are more advanced, there is no such perfect work as 190.

Su Cheng thought to himself: The three years of laid-off experience may have made his life difficult, but it sharpened his spirit and body.After a successful designer, how can he have 3 years to do design, 3 years to ponder carefully, and improve a little bit.

I just hope that Liu Qiu's 190 series will not change too much without more than a year of accumulation.

"Su Dong? Are you testing the machine?" Chen Zunian called out.He is still the director of Jinan Engine Factory, and Su Cheng, the owner of the factory, has become Su Dong.

"Test engine." Su Cheng restrained himself and watched the diesel engine start.

The dull roar is exhilarating.

Liu Qiu and others stood in front of the instrument, monitoring various data.

After a while, Su Cheng asked, "How is the situation?"

Liu Qiurou stroked Luan's shaggy hair, took two steps back, and said, "The situation is very good. If it passes, we can produce 1000 units this year if we work overtime."

"Oh, show me the blueprint." Su Cheng only knew a little about it, so he asked Liu Qiu to explain it to him.

Although there are still more than ten years to go before Daniel, Liu Qiu is still very experienced in explaining his works.

Su Cheng saw that he had already considered the reserved space, so he nodded secretly. The details can be used on the second-generation and third-generation models, so don't worry.

After all, they have already produced the 1 diesel more than 190 year ahead of schedule.

"Next, what are your thoughts on improving the diesel engine?" Su Cheng asked Liu Qiu directly. <, a few paragraphs are very clear, obviously already prepared.

If he combed his hair a little bit, the image might be better.

"Power is indeed a problem, and 500 horsepower is indeed a bit short. However, the current diesel engine is not easy to sell." Su Cheng didn't want to dampen Liu Qiu's enthusiasm, so he said: "Expanding the use of diesel engines is better than production. The diesel engine is more important, here, you have to pay more attention."

"Extended use?"

"The diesel engines we produce now are all used in construction sites and small power plants. Now all oil fields are waiting to be separated, and large orders have stopped, so we can't count on them. The remaining coal mines, metal mines, and industrial and mining vehicles are used Too few, and generally you won’t buy a 190 diesel engine. Therefore, you have to consider several improved versions of the diesel engine to make the diesel engine suitable for more places.”

Liu Qiu was dumbfounded, and asked, "Where can this thing be used?"

He is doing product design, not industrial design, and he really doesn't care about things like usage.

"How about on board. Diesel engines for ships. Fishing boats along the coast are very profitable now, and transportation is also very profitable. We provide them with better and cheaper diesel engines, and the sales will definitely be good." Su Cheng found one of the general assembly drawings and drew two lines with his nails , said: "The main structures such as cylinder bore, stroke, and cylinder center distance do not need to be changed, and the same is true for connecting rods, crankshafts, pistons, etc. However, the lubrication system and oil pan need to be changed to avoid oil spillage or The oil pump was sucked out. The intake and exhaust and cooling systems were also redone to adapt to the environment on board..."

Liu Qiu watched carefully, with a pen in his hand, scribbled on the notebook.

Before Su Cheng came, he had done his homework.Marine diesel engine is an important direction of diesel engine development.China has very few ships of its own. Especially since the 70s, the tonnage of ships in China has not been as much as that of Bao Yugang, the ship king of Hong Kong.But this phenomenon will change very quickly.

The first thing China needs are riverboats and offshore fishing boats, and then heavy-duty cargo ships and professional ships.

Just adapted to the improvement of the diesel engine.

Su Cheng briefly stated his thoughts, Chen Zunian listened with a learning attitude, and asked: "Then who should we turn to to buy diesel engines?"

"Whoever can get 5 yuan from the shipyard or even the local fishermen can take away our diesel engines."

"5 yuan? Our cost is more than 5 yuan." Liu Qiu jumped up.

Su Cheng suppressed him, and said, "I've found someone to do the calculations, and the material cost is about 5 yuan. The problem now is that our production cost is too high. We must find a way to reduce the cost, and the price cannot be too high. .”

"We used to sell 15 yuan." Liu Qiu muttered.

"Maybe in two years, we can still sell 15, not now." Su Cheng thought to himself, the cost of diesel engines will drop and fall in the future, and the thing that will remain unchanged for 10 years, that is, China, enjoyment is over. It's time to pay off the debt.

He raised his chin and asked, "How soon can you change the marine diesel engine?"

"It will take several months." Liu Qiu's interest was not high, and he asked, "Then ordinary diesel engines are no longer produced?"

"Production is determined by sales volume." Su Cheng knew that ordinary diesel engines would not have any sales within a year.It is unrealistic to expect the Ministry of Petroleum, which is about to be abolished, or PetroChina, which has not yet taken power.

Chen Zunian was a little apprehensive. They had been out of the market for two or three years, and they used to operate in a planned economy. They were naturally afraid of the market economy.

After two more sentences, Liu Qiu was depressed.

Only then did Su Cheng realize that he had hurt Liu Qiu's confidence, so he couldn't help comforting him, thinking: the future big cow, as if he doesn't care about anything, who would have thought that he is also a fragile young man now... Well, It's a fragile middle-aged man.

Liu Qiu mopped his fluffy hair, and said unhappily: "Su Dong, you are the boss, I will listen to you, but my diesel engine has no problems with the design, as long as it is produced, there will be no worries. Sales... we should still go all out to produce."

Two years from now, this may be the case.Sioux City shook his head secretly: There is no order for the oil system, and the annual output of 2 diesel engines is much worse than me giving away 1000 diesel engines for nothing.

However, this kind of judgment on the market is very boring to argue, and it will not get an accurate answer.

Su Cheng put his gaze on the drawing and said, "You said just now that there is no problem with the design?"

He suddenly remembered a classic mistake.

Liu Qiu was at a loss, and said "Not bad" with a hard face.

Su Cheng pulled a drawing, clicked on the right side, and asked, "How do you explain it here?"

"This is a safety protection device." Liu Qiu took a look, looked up and said, "This is to prevent the oil pressure from being too low, and it is also designed to automatically stop at overspeed. In addition, when the oil temperature is high and the water temperature is high, it will automatically alarm. .There is a butterfly valve on the intake pipe of the diesel engine. Once the emergency stop is made, the butterfly valve is closed to cut off the air.”

"However, when the butterfly valve is closed, the remaining air will cause the pressure of the cylinder to change. Isn't the pipeline here to bear the risk of backfilling?"

Liu Qiu looked suspiciously, turned his head twice, and then let out a soft "ah".

This is a classic small error on the 190, which appears occasionally, but is always misunderstood by users as their own faulty operation.Later, after the release, all the over [-] diesel engines in use underwent a large-scale replacement of parts, which Su Cheng had also seen.

Liu Qiu put his whole head on the drawing, regardless of whether he was fully engaged in production or not.

Chen Zunian thought about the "million yuan" that Su Cheng had promised to Director Ding at the banquet that day, but he couldn't ask.

Jinan Power Machine Factory is a wholly-owned company of Sioux City, and the investment must be made, but Chen Zunian is not sure how much Sioux City has.

After two days of delay, Su Cheng saw that the production was on track, so he returned to Dongying directly, and Chen Zunian had no choice but to hold back his words.

He is actually satisfied with the current situation. Although half of the workers are sent to Dongying to produce diesel engines, only half can work in Jinan, but it is much better than the fate of all being laid off and receiving living expenses.

Su Cheng returned to Dongying, but fell into the wine pool and meat forest.

Last year, he was just a college student with the title of Peking University, and he had no chance to accept and initiate banquets.

Identity today is very different.

Except for the cadres who are still running the department in Beijing, the big and small heads of Shengli Oilfield already know Sioux City and Dahua Industrial, which is a supplier to foreigners.

Anyone who can pull a little relationship will try to make an appointment with Sioux City.Among them, there are mainly office directors like Wei Kong and people like the director of the oil production plant.

Su Cheng has never been in contact with such a battle, and he is dizzy from drinking every day, but he can't do it if he doesn't go.Fortunately, after practicing the capacity for alcohol, I can slowly drink a catty and a half of Moutai, so I won't collapse immediately...

Moreover, being able to eat and drink a lot in the 80s was considered a good life.Su Cheng is a bachelor, and he can occasionally drag Shu Lan across the road. He has to thank the society for his tolerance. Don't even think about letting others cook, and it's "forbidden by heaven"!

Steaks and the like, if you eat too much, you will always get bored, but in the canteen of the oil field, there are always one or two famous chefs, with a salary of about 100 yuan, cooking famous dishes of 30 yuan a plate-this salary , is already very high in the country.

The people who entertain guests know that Sucheng likes delicious food, so they can borrow a new cook if they just look for it. Sucheng has gone from the first oil production plant to the tenth oil production plant. Shandong, Sichuan, Guangdong, Fujian, Jiangsu, Zhejiang, Hunan, and Anhui are all I almost ate it all...

On this day, as soon as Qu Guoda, the director of the No. 2 Oil Production Plant, sat down, his subordinates chased him in.

"Less oil." The visitor only said one sentence, and Qu Guoda rushed out, cursing in his mouth: "These oily people will not have a good year."
