Siheyuan starts from a better life

Chapter 734, third generation computers
Lying in bed again, he was still thinking about how to control costs. After all, this "Dongfeng" truck is a commercial model and does not have high requirements for comfort and interior decoration.

Therefore, Jiang Yan decided to cancel some unnecessary configurations, such as high-end seats, audio systems, independent air conditioners, etc., and focus the budget as much as possible on important aspects such as the power system and increasing load capacity.

He calculated that if only the most basic seats were configured, without too many interior decorations, and the money was spent on optimizing the engine, gearbox, frame, etc., the cost could still be controlled within 1 yuan.

Although some comfort will be lost, for a commercial truck that is mainly practical, it is the most critical to be able to significantly increase the load capacity and durability.

Jiang Yan secretly planned to develop a more comfortable passenger model after this "Dongfeng" truck was put into mass production.

The most urgent task at the moment is to trial-produce a localized freight truck with excellent performance and affordable price as soon as possible to completely change the current situation of my country's transportation industry.

Jiang Yan, who couldn't sleep, simply told Jiang Sirui, who was about to go to bed, and then got up and went to the study. After closing the door, Jiang Yan appeared in his small space the next moment.

Using the computer in the space, he found some of the design drawings of Dongfeng Motor that had been made public. Jiang Yan began to modify the original drawings.

Fortunately, his computer provided him with sufficient calculations and ready-made drawings for reference. After modeling on the computer, Jiang Yan could conduct thousands of simulation tests in a very short time and find To come up with the best parameters, he strives for perfection in every detail of the preparation, for fear of making any mistakes.

Although time in the space has slowed down a lot, after a long period of busy work, finally, the parameters of his drawings were almost completed. After leaving his own space, he saw the first ray of morning light shining into the house through the curtains.

When Jiang Yan handed him the stack of detailed engine design drawings, Master Wang only glanced at them, his eyes widened, and his mouth almost made an O shape.

Jiang Yan rubbed his slightly sore eyes and yawned. He moved his somewhat stiff hands and feet. Now he didn't even feel the fatigue from a night of hard work! Instead, he was full of energy.

After breakfast, Jiang Yan couldn't wait to go to the engine manufacturing workshop of the institute. He took out the carefully drawn drawings of the engine parts and handed them to the workshop director, Master Wang, one by one.

He looked at the various parameters marked on the drawing in surprise - 6 cylinders, 260 horsepower, turbocharging, high-strength alloy material. This was simply a dream!
Master Wang knows that given the current technical level of flower growers, it is not unusually difficult to successfully develop such a high-power, high-parameter diesel engine.

"Master Wang, this is the detailed parts drawing of the 6-cylinder 260-horsepower diesel engine I designed. Please arrange for the technicians to start processing and manufacturing according to the drawing. Time is tight and it needs to be completed as soon as possible." Jiang Yan instructed.

Master Wang is the workshop director temporarily transferred from the automobile factory to help.

He originally thought that this place was just for some ordinary engine trial production, but he didn't expect that he would be hit hard as soon as he took over the project.

But the design of every part on the drawing is so sophisticated that it doesn’t look like a lie at all.

Master Wang even saw some advanced design concepts that he had never seen before.

"Comrade Jiang Yan, did you draw this design yourself?" Master Wang looked at Jiang Yan in shock.

He heard there that the chief engineer here was very powerful. The optimized Jiefang engine they got last time was made by this Jiang Yan. Unexpectedly, in a short period of time, he actually came up with a new engine drawing. "Yes." Jiang Yan smiled and nodded.

"This is incredible!" Master Wang exclaimed, "As far as I know, according to the current technical level of flower growers, it is difficult to successfully develop such a high-power turbocharged engine. How did you come up with it?"

"I just researched it out of interest and made hundreds of design attempts. In short, the parameters on the drawing are what I confirm can be achieved, and the factory has the manufacturing capability."

Master Wang looked at Jiang Yan with great admiration. He really didn't know what was going on in the head of this handsome young man, but he could actually design an engine that far exceeded the current level.

"Okay, since you are the one who confirmed it, I will go all out to complete the trial production of this engine!" Master Wang said boldly.

Having said that, Master Wang immediately started arranging for the technicians to start work, and soon the sound of machine tools running could be heard in the research institute.

This Dongfeng Warrior uses a 6-cylinder 260-horsepower turbocharged diesel engine with a maximum power of 260 horsepower and a maximum torque of 85 kilograms.

It uses a 5 front speed and 1 rear speed manual transmission, front wheel positioning, and rear wheel double reduction differential.

The total weight of the vehicle can reach 15 tons, making it the largest heavy-duty freight vehicle at that time.

What's even more rare is that Jiang Yan added a fuel injection system to the engine, which can accurately control the fuel injection time and save fuel and consumption. The gearbox also implements semi-automatic shifting and can automatically select the appropriate gear according to the load.

This was undoubtedly a huge innovation at the time.

After mass production of Dongfeng Warriors, each one is expected to cost only 1 yuan, which is still affordable.

After arranging these tasks, Jiang Yan did not stop, but immediately threw himself into the next plan. Integrated circuits are used to produce third-generation computers.

The third generation computer is the third generation integrated circuit computer. The characteristic is that the main functional components of the computer are composed of small and medium-sized integrated circuits (less than a thousand logic gates integrated on each chip) (written in Spanish as SSI, MSI); the main memory uses semiconductor memory. The computing speed can reach hundreds of thousands to millions of basic operations per second. On the software side, operating systems are getting better and better.

The further development of computer software technology, especially the gradual maturity of the operating system, is a significant feature of the third generation of computers. The development of multiprocessors, virtual memory systems and user-oriented application software has greatly enriched computer software resources. In order to make full use of existing software and solve software compatibility problems, serialized computers have emerged. The most influential is the IBM-360 computer series developed by IBM.

When computer language developed into the third generation, it entered the "human-oriented" language stage. The third generation language is also called "high-level language". A high-level language is a programming language that is close to what people are used to. It allows you to write problem-solving calculation programs in English. The operation symbols and expressions used in the program are similar to the mathematical expressions we use every day. High-level languages ​​are easy to learn and have strong versatility. The written programs are relatively short and easy to promote and communicate. It is an ideal programming language. High-level languages ​​were developed from the mid-50s to the 70s. Some popular high-level languages ​​have been adopted by most computer manufacturers and solidified in the computer's memory.

In the past few years, the country has developed a second-generation computer. Its computing power is no worse than that of foreign computers. However, the second-generation computer is still too bulky. Otherwise, Jiang Yan would not have the idea of ​​developing a third-generation computer. .
