Two weeks later, the experimental 190 diesel engine was moved off the production line.

A 190-liter 500 hp diesel engine is quite a big guy and you have to carry it down with professional handling equipment. Placed outside, it looks like a prefabricated house.

Compared with the diesel engines produced by Jinan Power Engine Factory, the 190 series has made great progress in power and energy consumption. Of course, it still has a lot of room for improvement, to the next 20 years or even 30 years, the 190 series of improved D type, improved H type is still on sale, Liu Qiu is a big take, is this 190 diesel engine.

In the memory of Sioux City, after PetroChina re-invested in Jinan Power Engine Factory, they tried several new products, but the Jedi counterattack was still the 190 diesel engine. Due to its reliable performance, it once forced the foreign Chapter 93 marine diesel engine diesel engine brand to Liangshan, and finally could only rely on bundled sales to survive.

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, bore-stroke ratio, partial load minimum fuel consumption rate, and other indicators, compared with similar products, there is a degree of improvement, the most rare thing is that he also took into account the future improvement needs, and spent a lot of energy to make a reservation. This is the fundamental reason why the 190 series has been able to sell well for 30 years.

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

Su Cheng thought to himself: The three-year layoff experience may have made his life difficult, but it sharpened his spirit and body. After success, where can the designer have 3 years to design, 3 years to carefully ponder and improve?

I only hope that there is less than a year of accumulation, Liu Qiu's 190 series. Don't change too much.

"Su Dong, is it a test machine?" Chen Zunian shouted. He was still the director of the Jinan Power Engine Factory, and the owner of the factory, Su Cheng, became Su Dong.

"Test machine. "Sioux City has relented in its spirit. Watch the diesel engine start.

A dull roar. Exhilarating.

Liu Qiu and others Chapter 93 Marine diesel engine stood in front of the instrument, monitoring various data.

After a while, Su Cheng asked, "How's it going?"

Liu Qiu rubbed his unkempt hair and took two steps back. "The situation is very good, if it passes." If we work overtime, we will be able to produce 1,000 units this year. ”

"Oh, show me the drawings. "Sioux City only knows a little scratch about it. Let Liu Qiu explain it to him.

Although there are still more than ten years to go before the big bull. But explaining his own works, Liu Qiu is still very sophisticated.

Su Cheng saw that he had already considered the reserved space, so he nodded secretly, picking out the details can be used on the second and third generation models, no need to worry.

After all. They have already produced 190 diesel engines more than 190 years ahead of schedule.

"Next, what are your thoughts on the improvement of the diesel engine?" Su Cheng asked Liu Qiu directly.

"I think. Increasing power is the primary consideration......" Liu Qiu held his head high, and said a few paragraphs very clearly, obviously prepared for a long time.

If he combed his hair a little, he might have looked better.

"Power is a real problem, 500 horsepower is a bit less. 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 a more important thing than producing diesel engines, here, you have to pay more attention." ”

"Expanding?"

"The diesel engines we produce now are all used in construction sites and small power plants. Now that the oil fields are waiting to be separated, large orders have stopped, and they cannot be counted on. The remaining coal mines and metal mines, the amount of industrial and mining vehicles is too small, and they generally do not buy 190 diesel engines. Therefore, you have to consider several modifications of the diesel engine, so that the diesel engine can fit in more places. ”

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

He is in the business of product design, not industrial design, and he really doesn't care about things like use.

"How on board. Marine diesel engines. Now the fishing boats along the coast are very profitable, and the transportation is also very profitable, and we provide them with better and cheaper diesel engines, and the sales will definitely be good. Su Cheng found one of the final assembly drawings, scratched two lines with his fingernails, and said: "The main structures such as cylinder diameter, stroke, and cylinder core distance do not need to be changed, and the same is true for connecting rods, crankshafts, pistons, etc., but the lubrication system and oil pan should be changed, so as not to spill the oil or suck the oil pump out in the case of shaking at sea." The intake, exhaust and cooling systems have also been redone to adapt to the environment on board......"

Liu Qiu looked carefully, holding a pen in his hand, and scribbled on the notebook.

Before Sioux City came, he had done his homework. Marine diesel engine is an important direction for the development of diesel engine. There are very few ships of their own, especially since the 70s, the tonnage of ships in the whole country is not as much as that of Hong Kong ship king Bao Yugang. But this phenomenon will change very quickly.

What China needs first is inland river vessels and offshore fishing vessels, and then heavy-duty cargo ships and specialized vessels.

Just adapted to the improvement of diesel engines.

Su Cheng briefly said his thoughts, Chen Zunian listened with a learning mentality, and asked, "Then who do we find to buy diesel engines?"

"Shipyards, even private fishermen, whoever can get 50,000 yuan can take our diesel engines. ”

"50,000 yuan? Our cost is more than 50,000 (the fastest update) block. Liu Qiu jumped up.

Su Cheng suppressed him and said, "I have calculated it with someone, and the cost of materials is 50,000 yuan." The problem now is that our production costs are too high, and we must find ways to reduce costs, not too high prices. ”

"We used to sell for 150,000. Liu Qiu muttered.

"Maybe in two years, we can still sell 150,000, but not now. Su Cheng thought to himself, the cost of diesel engines in the future has already fallen and fallen, and the price will remain unchanged for 10 years and 20 years, that is, the country will enjoy the end, and it will be time to repay the debt.

He lifted his chin and asked, "How soon will you be able to get a marine diesel engine?"

"It's going to take months. Liu Qiu's interest was not high, and he asked: "Isn't the ordinary diesel engine produced?"

"Production is based on sales. "Sioux City knows that ordinary diesel engines will not have any sales in a year. Count on the soon-to-be-abolished Ministry of Oil, or PetroChina that is not yet in power. It's all unrealistic.

Chen Zunian was a little apprehensive, they had been out of the market for two or three years. In the past, it was also the mode of operation of the planned economy. There is an innate fear of the market economy.

After saying two more sentences, Liu Qiu was sullen.

Su Cheng realized that he had hit Liu Qiu's confidence. I couldn't help but comfort him again, thinking: the future bull. As if he didn't care about anything, who would have thought that he was also a fragile young man now...... Well. It's fragile middle-aged people.

Liu Qiu touched his unkempt hair. said unhappily: "Su Dong, you are the boss, I listen to you, but I have no problem with the design of this diesel engine, as long as it is produced." Don't worry about running out of sales...... We should still go all out. ”

Two years later, this may be the case. Sioux City shook its head secretly: there are no orders for the oil system. With an annual output of 1,000 diesel engines, it is much more than giving away 200 pumping units for free.

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

Su Cheng then looked at the drawings and said, "You just said that there is no problem with the design?"

He suddenly remembered a classic mistake.

Liu Qiu was at a loss, and said "good" with a hard face.

Su Cheng pulled over a drawing, tapped to the right side, and asked, "How do you explain here?"

"It's a safety device. Liu Qiu glanced twice, raised his head and said: "This is to avoid the oil pressure is too low, and the function of automatic parking over speeding is also designed." In addition, if the oil temperature is high and the water temperature is high, it will also automatically alarm. There is a butterfly valve on the intake line of the diesel engine, and once the emergency stop is made, the butterfly valve is closed, and the air is cut off. ”

"However, when the butterfly valve is closed, the residual air will change the pressure of the cylinder, and the pipeline here will not bear the risk of backfilling. ”

Liu Qiu looked puzzled, his head made two bends, and then he let out a soft "ah".

This is a classic little mistake on 190, which occasionally occurs, but is always misunderstood by users for their own misoperation. Later, after the release, all the more than 10,000 diesel engines in use underwent a large-scale replacement of parts, and Sioux City also saw it.

Liu Qiu's whole head was on the drawing, and he didn't care whether he was going all out to produce or not.

Chen Zunian thought about the "20 million yuan" promised to Director Ding at the banquet that day, but it was not easy to ask.

Jinan Power Engine Factory is a wholly-owned company of Suzhou City, and the money must be invested, but Chen Zunian is not sure how much money Suzhou City has.

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

He is actually quite satisfied with the current situation, although half of the workers were sent to Dongying to produce diesel engines, and only half of them could work in Jinan, but it was much better than the fate of all the laid-off workers receiving living expenses.

Sioux City returned to Dongying, but fell into the wine pond and meat forest.

Last year, he was just a college student with the title of Peking University, and he didn't have the opportunity to accept and initiate a banquet.

Today's identity is very different.

In addition to the cadres who are still running in Beijing, the heads and brains of Shengli Oilfield, large and small, already know about Sioux City and Dahua Industrial, which is a supplier to foreigners.

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

Su Cheng had never been in contact with such a battle, and he drank dizzily every day, but he couldn't go but go. Fortunately, the amount of alcohol has been practiced, and I slowly drank a pound and a half of Moutai, so that it would not collapse immediately......

Moreover, being able to eat and drink in the 80s is considered a good life. Su Cheng is a bachelor, and he can occasionally pull Shulan to press the road, and he has to thank the society for tolerance, let people cook or something, don't think about it, and "God doesn't allow it"!

Steak and other things are always boring when you eat too much, but in the oilfield canteen, there are always one or two famous chefs who take a salary of about 100 yuan and cook a plate of famous dishes for 30 yuan -- this salary is already very high in China.

The people who invite guests know that Su Cheng likes food, just look for it, you can borrow a new chef, Su Cheng from the first oil production plant to the oil production ten times, Shandong, Sichuan, Guangdong, Fujian, Jiangsu, Zhejiang, Hunan, Anhui is almost all eaten......

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 person who came only said one word, and Qu Guoda rushed out, scolding in his mouth: "These oil guzzlers are not having a good year." ”
