Siheyuan starts from a better life

Chapter 167, Two Cylinder Diesel Engine
The north wind was blowing, and Jiang Yan who had just walked out of the downstairs was shivering.

When Jiang Yan came to the experimental workshop, deputy director Yang brought several workshop directors and technical masters there.

"I only drew a part of this drawing, which contains the drawings of the diesel engine. These are the exploded drawings of the equipment."

"Okay, okay, Mr. Jiang has worked hard,"

Deputy Factory Manager Yang took over the blueprint in Jiang Yan's hand and looked at it with excitement.

"Are you going to work the night shift tonight?" Jiang Yan asked.

"On the night shift, I have already greeted the workers, and I will make them all night tonight, otherwise I will feel uneasy."

"The logistics have also been arranged for supper. Comrade He Yuzhu will do it himself."

Director Li, who was next to Deputy Director Yang, also interrupted.

Hearing this, Jiang Yan nodded. When he came, he guessed that if there were no accidents, he would probably work all night tonight.

"The materials for the engine are all ready!"

Jiang Yan asked Deputy Director Yang a question.

"Ready, Secretary Wang and Director Zhang have made more than a dozen copies with their own channels."

"That's fine. After a while, you will distribute the drawings according to the type of work. I will lead the workers to do the cylinders of the diesel engine."

"By the way, I have already written the materials and requirements on the drawing. There are many gear parts. Our machine can only do rough machining. I guess the fitter will need a little effort."

"It doesn't matter. All the fitters above level [-] in our factory are on standby in the next workshop. Director Li will go over and watch when the time comes."

Hearing that Deputy Director Yang had made arrangements, Jiang Yan finally felt relieved.

Then Deputy Factory Manager Yang called some workers over and began to distribute the drawings.

"Deputy Director Yang divided the workers into groups according to different types of work, and temporarily appointed some people as group leaders."

Director Li next to him explained to Jiang Yan in a low voice.

Each temporary team leader got his own drawings and started to organize workers to produce. The machine tools roared in the experimental workshop that had been silent for a day.

And Jiang Yan organized the workers to start production with the drawings of the cylinder.

Because of his previous experience in producing automobile engines, this time he commanded the workers in an orderly manner. In order to catch up with the schedule, Jiang Yan's mold making here is basically a sixth-level worker. When forging the rough edges, Liu Haizhong personally went into battle.

The mold was made quite smoothly. After the sand mold was made, watering began again. After everything was completed, Jiang Yan came to the side of Deputy Director Yang.

"The cylinder has been poured, and the next step is to wait for cooling and then process. I have already arranged the next thing."

Hearing Jiang Yan's report, Deputy Factory Director Yang nodded, said hard work but was silent.

Jiang Yan waited for less than 2 minutes, and the parts began to be delivered to Jiang Yan one after another.

Jiang Yan glanced at the parts that were delivered. These parts are basically the parts of corn threshers and manpower seeders. These parts are not difficult, and the processing is naturally fast.

Seeing these parts, Jiang Yan instructed the technicians in the technical department to start assembling the tested parts.

"Okay." Hearing the voice of the technician, Jiang Yan and Deputy Director Yang turned their heads at the same time, and a corn thresher appeared in front of their eyes.

"Put it aside for now!" Jiang Yan lost interest after seeing this thing, but he still told the technician.

The technician took the assembled corn thresher to the right side of the workshop against the wall.

During this period, corn threshers and human planters were assembled and placed in a row.

Seeing these human machines, all the leaders went up to have a look, and felt that they could do it.Arrange workers to put these things into the warehouse and wait for tomorrow's inspection.

And all the leaders' thoughts are once again put on the diesel engine, which is the most important thing.

"Mr. Jiang, the parts of the diesel engine came out." Xiao Zhang, the technician who took it by himself, came to Jiang Yan with the parts he knew, and handed them to Jiang Yan like an ordinary treasure offering.

"Quickly measure it." Deputy Factory Manager Yang told the technician excitedly.

Hearing the order from Deputy Director Yang, Xiao Zhang took it out to test the power and began to test the newly made parts.

"The size and design are consistent, and the product is qualified."

After the test, Xiao Zhang loudly reported to Jiang Yan and Deputy Director Yang.

"Okay, okay, a good start, really a good start."

Starting from this part, the parts for making diesel engines were sent over one after another, and Jiang Yan directed the technicians to start testing these parts.

"This crankshaft is pretty good. It's almost perfect. Even with a machine, it's hard to make such a quality." Jiang Yan praised a crankshaft that had just been inspected.

The surface of this crankshaft is very smooth, and there is not a single burr on it. It is not an exaggeration to say that it is a handicraft.

Hearing Jiang Yan's praise, Wu Fei, the director of the third workshop who was helping to count and sort beside Jiang Yan, was overjoyed. The parts such as the crankshaft were completed by his team.

"Little Jiang, isn't the crankshaft of our diesel engine a bit long? I've seen the crankshaft of a car engine, but it's very short!"

Well, when he heard the question from Deputy Factory Manager Yang, Jiang Yan knew that this was a layman, and he was most afraid of this kind of leader who didn't understand in normal work.

However, Jiang Yan still patiently explained: "Generally speaking, the crankshaft size of a diesel engine is larger than that of a gasoline engine with the same displacement. This is because the compression ratio of a diesel engine is high, and a larger crankshaft is required to withstand greater pressure and torque. In layman's terms, the greater the torque, the greater the strength, and if it is put on a car, it will pull more things."

After Jiang Yan finished speaking, he stopped to look at the thoughtful Deputy Director Yang and then spoke.

"The working cycle of a gasoline engine is the ignition cycle, and the size of the crankshaft is relatively small. In addition, the size of the crankshaft is also affected by the speed and power of the engine. High-power and high-speed engines require larger crankshafts to withstand greater loads and vibration."

"That is to say, the speed of the gasoline engine affects the speed. In layman's terms, he has little strength but runs very fast."

In his previous life, Jiang Yan knew that the fastest F1 car in the world could rotate at more than 20000 revolutions per minute, but the world's strongest diesel engine was less than 120 revolutions per minute.

Don't underestimate this slow-speed diesel engine, and don't feel that it is very rustic. In fact, more than 90.00% of the tanks, submarines and large surface warships in the world use diesel engines.

The one designed by Jiang Yan can barely be regarded as a micro engine.The power is far worse than that of the tractors produced later, but it is quite enough for this era in China.

"Xiao Jiang, you mean they can't run fast, but they can get more goods, right!"

"Director Yang" It's okay for you to understand this way. Our walk-behind tractor is rated at one ton, but if you pull twice as much, you can probably run it, but the speed is a little slower. "

"I'm talking about it, we originally invented machines for farming, why do you let them run so fast!"

"That's right, Xiao Jiang, you are right. The main duty of the walking tractor is to plow the land, and the transportation is incidental, but it doesn't need to be so fast, it doesn't need to be."

Don't look at Deputy Factory Manager Yang's suddenly enlightened look, Jiang Yan guessed that he only had a half-knowledge after listening to his explanation, and maybe he just remembered the relationship between the speed of the speed and the strength.
