Siheyuan: My Northeastern Farmhouse

Chapter 224 Incredible

Director Zhou and Secretary Huang couldn't help but look at each other again because of what they had just seen, and laughed "haha".

Qian Weichang assigned the drawings in his hand to Li Youshan and Wu Zhonghua according to the engine's lubrication system and starting system, and he lowered his head again to study the fuel supply system of the drawings, especially the turbocharging part. Hearing the questions from Director Zhou and Secretary Huang, he pointed at Gu Weijun and said, "Gu Weijun designed it!"

"Look now, it's fine in theory!"

"If it can be produced, it will at least be a world-class four-cylinder diesel engine!"

“Some ideas might even be top notch!”

Director Zhou and Secretary Huang were shocked again! The two of them opened their mouths at the same time and looked at Gu Weijun in disbelief, "Hiss!" The temperature in the casting workshop dropped by two degrees!

Is this still the Gu Weijun I know? They say that people are treated with admiration after three days of separation, but nothing is as exciting as yours!

You are gouging people's eyes!

Qian Wei asked Gu Weijun about the design parameters of the engine without raising his head: "What are the theoretical parameters and power of the engine you designed?"

Gu Weijun opened his mouth and said, "Water-cooled four-cylinder direct injection, naturally aspirated, using a gear oil pump and "A" type mechanical injector, equipped with a rotary injection pump, using an overhead valve + bottom camshaft valve mechanism, exhaust The capacity is 2.771CC, the lubrication method: pressure cycle splash compound type; the cooling method: closed pressure cycle; the output power is 57 kW/3600 rpm, the torque is 172 Nm/2000 rpm! The maximum idling speed is 4200 rpm!”

"With turbocharging, the output horsepower can reach 85 kilowatts and 95 kilowatts!"

Qian Weichang was also shocked again. Is the design data so excellent?

If this engine can really be put into use, domestic 3-5 ton light trucks will usher in innovative improvements!

No more troublesome problems of immature engines!

Not only that, you can also get innovative improvements when installed on jeeps and cars!

Not to mention anything else, compared with the gasoline engine used in the jeeps currently supplied by the Beijing Automobile Manufacturing Factory to the army, it is far behind! Just beat him up!

Moreover, from the design and structure analysis of this engine, its structure is simple and compact. What does this mean? The failure rate is low! It is also very suitable for military use!

Qian Weichang made a "tsk tsk" sound unconsciously. How did he come up with these mechanical structures? The design is so beautiful!

This good mechanical design is so eye-catching! It fully embodies the beauty of machinery and mechanics!

Gu Weijun on the side listened to the unanimous praise from the three great masters, including Qian Weichang, and couldn't help but raise the corners of his mouth and raise his brows!

This is Gu Weijun. If it were anyone else, he would probably be three feet above the ground!

Suddenly, Qian Weichang pointed to a structure in the drawing and asked: "Gu Weijun, what structure is this?"

"Oh!" Gu Weijun picked it up at his fingertips, "High-pressure fuel injection!"

"what about this?"

"Dispense pump!"

"What principle did these two people use?"

"This" Gu Weijun was dumbfounded. I didn't know. He pointed to his head and said, "A flash of inspiration!"

"Well" Qian Weichang fell into deep thought, and then pointed to another structure, "This crankshaft you designed?"

"Eight Balanced Gravity!"

"The principle?"

"Uh" Gu Weijun turned his eyes to the upper right and murmured: "Talent design?"

Qian Weichang was speechless again, "How did you come up with the two overhead valve + bottom camshaft valve distribution structures and the turbocharger structure you just mentioned?"

Gu Weijun nodded seriously, "An explosion of inspiration?"

The fat old man was completely speechless. Forget it, some geniuses are just incomprehensible! Design does need inspiration, but Gu Weijun's inspiration is a bit too overwhelming.

Of course, Gu Weijun either can't explain it, or it's too clumsy. We are not a popular science article!

Seeing this, Li Youshan and Wu Zhonghua also smiled and did not ask any questions.

Director Zhou's heart froze. Is this still reliable? Someone on the side quickly asked: "Scientist Qian, can the design drawings of this engine still be produced?"

"Is it difficult?"

Qian Weichang pondered for a while and said, "Try it!"

"Gu Weijun has adopted many unique technologies on this engine, and these have yet to be verified!"

"Our cast iron alloy in the cylinder block is fine. The main difficulty lies in the multiple pores in the cylinder block. Furthermore, the crankshaft is very well designed, but it is difficult to process. It requires a little bit of processing by a master craftsman!"

“Finally there’s the turbo part.”

"Fortunately, Gu Weijun has calculated all the parameters of the parts!" As long as there is hope, Factory Manager Zhou rejoiced, "Scientist Qian, you go to the test workshop first. I will immediately ask several senior engineers from our factory to come over and take a look at what's going on today. Can we get a test machine?"

"If possible, build this engine and install it directly on my Jeep! When I go to the First Machinery Department, I will use our new engine in the Jeep!"

"Let them see that our Shijingshan Iron and Steel Plant is first-class in steelmaking and iron-making, and it is also first-class in industrial manufacturing!"

"I envy them to death!"

Secretary Huang beside him teased: "The tractor won't run? Such an excellent single-cylinder diesel engine is also our achievement!"

Director Zhou waved his hand, "Then let's take turns!"

"Haha!" Everyone laughed.

Qian Weichang smiled and put the drawings together again for Gu Weijun to put away. At the same time, he replied to Director Zhou, "Director Zhou, this engine is not as easy to process as a single-cylinder diesel engine!"

"Especially in the initial trial production stage! There are probably still a lot of difficulties to overcome!"

"We will be successful if we can physically manufacture this engine within a week!"

“And we have to rely on many master craftsmen to polish it by hand!”

"This is still making an ordinary naturally aspirated version! If it is turbocharged, it will probably take longer!"

Director Zhou waved his hand, "Our job is not to be afraid of difficulties!"

"Wang Jinxi of Daqing said it well, if there are difficulties, you have to go up, and if there are no difficulties, you have to go up even if you create difficulties!"

"Old Huang, you accompany Scientist Qian and Professor Wu to the test workshop to study with the master workers how to make this new diesel engine? Professor Li and I continue to stare at the casting of this column!"

"Let's not waste any time!"

"Xiao Miao!" Director Zhou called the factory secretary, "Go and invite several senior technicians from our factory to the test workshop, and also call Director Liu Feng from the machine repair shop!"

"I have to tell the masters that they must cooperate with Scientist Qian and Professor Wu!"

"We can not only produce tractors now, but also cars in the future!"

"That's right!" Secretary Huang interjected and asked Gu Weijun: "Speaking of tractors, Dajun, have you designed the agricultural machinery I mentioned to you last time?"

"Director Zhou has already said hello to Red Star Commune in advance!"

“During spring plowing, just drive over and help!”

"It doesn't look like it's been a few days!"

Gu Weijun nodded quickly, "It's already designed! There are too many drawings. I put the drawings of agricultural machinery on the table in the test workshop!"

"Yes!" Secretary Huang nodded with satisfaction! "Then let's ask the masters to make it quickly this time!"

"Our Red Star Commune will show off its skills in a week!"

Secretary Huang didn’t understand the difficulty of design, but Qian Weichang and Wu Zhonghua around him did, and they also clearly understood the difficulty of designing a machine!

Qian Weichang and Wu Zhonghua once again looked at Gu Weijun with disbelief, asking in their hearts, am I getting old?

Is it so easy to design a machine now?

This newly designed four-cylinder diesel engine is beyond imagination! Are so many new structures copied directly from your head?

That's all, but there is still room for designing agricultural machinery?

Just doodling or do you really have a lot of talent?

No need to rush, Qian Weichang, Secretary Huang and others rushed to the test workshop office, all wanting to take a look!

　I originally wanted to write about a person who is like an iron rice or a steel, but then I thought about it and gave up. I strayed from the topic. I borrowed the name of the person.
