Lying back in bed, he's still thinking about how to control costs. After all, this "Dongfeng" truck is a commercial model, and it does not have high requirements for comfort and interior.

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

He calculated that if only the most basic seats are configured, too many interiors are not added, and then the money is spent on optimizing the engine, gearbox, frame, etc., the cost can still be controlled within 10,000 yuan.

Although some comfort will be lost, for a commercial truck that focuses on practicality, it is crucial to be able to significantly increase the load capacity and durability.

Jiang Yan secretly planned to wait for this "Dongfeng" truck to be put into mass production, and then develop a more comfortable passenger model.

At present, the most urgent task is to try to produce a localized freight vehicle with excellent performance and affordable price as soon as possible, so as to completely change the status quo of China's transportation industry.

Jiang Yan, who couldn't sleep, simply told Jiang Sirui, who was about to sleep, and then got up and came to the study, and 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, and Jiang Yan began to revise and modify the original drawings.

Fortunately, his computer provides himself with sufficient calculations, and ready-made drawings can be used as a reference, after modeling on the computer, Jiang Yan can conduct thousands of simulation tests in a very short time to find out the best parameters, and he strives for perfection in every detail of the preparation, for fear of any mistakes.

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

Jiang Yan rubbed his slightly sour eyes, yawned, he moved his somewhat stiff hands and feet, he didn't feel the fatigue of fighting all night now! On the contrary, he was in high spirits.

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

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

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

He originally thought that this was just some ordinary engine trial production, but he didn't expect that as soon as he took over this project, he was hit by a lot of impact.

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

He looked at the parameters marked on the drawings in amazement - 6 cylinders, 260 horsepower, turbocharged, high-strength alloy material, it was a dream!

Master Wang knows that in terms of the current technical level of the flower planter, it is not difficult to successfully develop such a high-power, high-parameter diesel engine.

But the design of each part on the drawings is so well-designed that it is not at all deceiving.

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

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

He heard over there that the chief engineer here is very powerful, and the optimized liberation engine they got last time was made by this Jiang Yan. Unexpectedly, in a short period of time, he actually took out a new engine drawing.

"Yes." Jiang Yan smiled and nodded.

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

"I just studied it out of interest and made a billion design attempts. In short, the parameters on the drawings are what I confirm can be realized, and the factory has this manufacturing capacity. ”

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

"Okay, since you are sure, I will go all out to complete the trial production of this engine!" Master Wang said heroically.

After that, Master Wang immediately began to arrange for the mechanics to start work, and soon the sound of machine tools running came from the research institute.

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

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

With a total weight of up to 15 tons, it was the largest heavy cargo vehicle at the time.

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

This was undoubtedly a huge innovation at the time.

After the mass production of Dongfeng Mengshi, it is expected that the cost of each will only be 10,000 yuan, which is still affordable.

After arranging these tasks, Jiang Yan did not stop, but immediately threw himself into the next plan. It is the use of integrated circuits to produce the third generation of computers.

The third generation of computers is the third generation of integrated circuit computers. It is characterized by small and medium-sized integrated circuits (within 1,000 logic gates integrated on each chip) (written in Western as SSI, MSI) to form the main functional components of the computer; The main memory is semiconductor memory. The speed of operations can range from hundreds of thousands to millions of basic operations per second. In terms of software, the operating system is getting better and better.

The further development of computer software technology, especially the gradual maturity of operating systems, is a salient 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 appeared. The most influential is the IBM-360 computer series developed by IBM.

When computer language reached the third generation, it entered the stage of "human-oriented" language. Third-generation languages are also known as "high-level languages". A high-level language is a programming language that is close to what people are used to. It allows the calculation program to be written in English, and the operator symbols and equations used in the program are similar to the mathematical formulas we use every day. The high-level language is easy to learn, versatile, and the written program is relatively short, which is easy to promote and communicate, and is an ideal programming language. High-level languages developed from the mid-50s to the 70s, and some popular high-level languages have been adopted by most computer manufacturers and solidified in the memory of computers.

A few years ago, the second generation of computers has been developed in China, and his computing power is no worse than that of foreign countries, but the second generation of computers is still too cumbersome, otherwise Jiang Yan would not have the idea of developing a third-generation computer.
