Siheyuan: I am different He Yuzhu

According to He Yuzhu's instructions, the maintenance workshop quickly formed an off-road vehicle R&D team with Li Yang as the core. They decided to use a non-load-bearing body as the chassis of the off-road vehicle and chose the simplest leaf spring as the shock absorption system. In general, this off-road vehicle looks like four wheels plus a few chairs, which is very simple and crude.

When the workers finished making the prototype according to He Yuzhu's design, they temporarily installed the six-cylinder engine and gearbox that were previously made based on Dodge trucks on the car. After everything was ready, the test driver started the off-road vehicle chassis with only the frame, and after engaging the gear, the vehicle rushed out instantly. The test driver excitedly drove the car around. After returning to the maintenance workshop, he said excitedly: "This car is so powerful to drive! The power is amazing, and the acceleration is extremely fast. I have never driven such a powerful car!"

He Yuzhu smiled and said to Li Yang beside him: "Master Ma is really telling the truth. This car must be powerful. The engine and gearbox on it are used on trucks. Trucks can run so fast with this engine and gearbox to pull several tons of cargo. It would be strange if a bare car body doesn't accelerate fast."

Li Yang nodded and agreed, "Yes, but in this case, the performance of the off-road vehicle should be very good."

He Yuzhu continued, "Of course it's good, and there's more to it. Teacher Li, the next part is the highlight. You will have to lead the students to organize the workers to improve the rear axle, gearbox and engine. After all, we can't just install the things on the truck on the off-road vehicle. That would result in too high fuel consumption and poor economic efficiency of the off-road vehicle. Our country's oil resources are very scarce. By the way, not only the engine on the off-road vehicle, but also the engine of the truck that is copied must improve fuel economy, improve the thermal efficiency of the engine, and reduce fuel consumption."

Li Yang frowned, thought for a moment and said, "Indeed, off-road vehicles do not need such a large power output. We need to adjust the coordination between the rear axle, gearbox and engine to make them more suitable for off-road vehicle usage scenarios."

He Yuzhu nodded with satisfaction and added, "You are right, Mr. Li. Off-road vehicles do not consider load capacity, but have higher speed requirements. Therefore, we need to improve the gearbox and rear axle to increase the speed of off-road vehicles. In addition, we must also pay attention to the tuning of the engine to ensure sufficient power while controlling fuel consumption."

After listening to He Yuzhu's words, Li Yang secretly admired his professional level, and then asked: "Okay, I understand. By the way, Team Leader He, do you have any ideas about the appearance of the car body?"

He Yuzhu smiled and replied, "Yes, take a look at my drawing. How is it?" He Yuzhu took out a piece of paper from his pocket and handed it to Li Yang. This was the appearance of an off-road vehicle that He Yuzhu had drawn based on the appearance of the later Wrangler off-road vehicle and combined with some of his own ideas.

Teacher Li Yang carefully took the drawing handed over by He Yuzhu, unfolded it gently, and looked focused and curious. When he saw the off-road vehicle design on the drawing, his eyes suddenly widened and a surprised expression appeared on his face.

"Wow! Team Leader He, the SUV you drew is so beautiful! I have never seen such a good-looking car." Teacher Li Yang exclaimed, his voice full of excitement and appreciation.

He Yuzhu smiled slightly, with a hint of pride in his eyes. He explained, "Teacher Li, actually, this design was made by referring to the front of the Willys Jeep in America and combining some of my own ideas."

Hearing this, Teacher Li Yang couldn't help but exclaimed: "I see! Your creativity is really admirable. This off-road vehicle not only has a unique appearance, but also has smooth lines, giving people a strong visual impact. Just looking at the drawings gives people a feeling that this car is full of power."

He Yuzhu was very pleased to hear the praise from Teacher Li Yang. He said modestly: "Thank you for the compliment, Teacher Li. I also referred to the designs of other jeeps, not all of them are my own."

Teacher Li Yang nodded to show his understanding. Then, he looked at the drawing in his hand, thought for a moment and said, "Team Leader He, since you already have such an outstanding car exterior design, then we need to focus on developing an engine and gearbox suitable for off-road vehicles. Only in this way can the off-road vehicle exterior you designed become a reality as soon as possible."

He Yuzhu agreed, adding: “Yes, Mr. Li, this is also one of my biggest concerns. I hope we can find a suitable solution as soon as possible to ensure the performance and quality of the off-road vehicle.”

Finally, Mr. Li Yang said confidently: "Okay, I will definitely go all out to develop an engine and gearbox suitable for off-road vehicles as soon as possible. I believe that we will be able to see this amazing off-road vehicle come out soon."

"Teacher Li, I didn't mark the dimensions on the drawing because I don't know how big the frame will be when it's built. So I'll have to trouble you to determine the exterior dimensions based on the built frame."

"In addition, there is one more thing I need to tell you. I suggest that when determining the size of the off-road vehicle's exterior, we should try to consider using domestically available parts as much as possible. This will not only reduce costs but also improve efficiency. For example, for the front lights on the off-road vehicle, can we consider directly using the lights on the trucks produced by the Northeast Automobile Factory? In this way, there is no need to redesign and manufacture the lights, and we can directly use existing products. For example, can the size of the glass on the door and the windshield be the same as that of domestic trucks? In this way, can we reduce the difficulty in purchasing parts?"

"If we can achieve these, it will greatly reduce our difficulties in purchasing parts, and we can also save time and costs. Of course, if we really can't find suitable existing parts, then we will consider customization or self-development. I hope you can understand my idea and take this into full consideration during the design process. Similarly, if after solving all the problems of imitating Dodge trucks, when determining the production drawings of domestic trucks, I hope you will also take this into consideration, especially for some parts. We don't have to produce an identical one according to the Dodge truck. Especially for some parts that are difficult to process in appearance, we can directly improve them." He Yuzhu said earnestly.

Hearing this, Teacher Li couldn't help but give a thumbs up: "Team Leader He, your suggestion is very good! Indeed, if we can use existing parts, we can not only save costs, but also avoid some technical difficulties. At that time, it will definitely save a lot of trouble." He smiled and nodded in agreement.

He Yuzhu smiled slightly: "That's good, I believe that as long as everyone works together, we will be able to build an off-road vehicle of our own!"

"We will definitely be able to produce our own off-road vehicle for the country of Donggu." Teacher Li Yang said with a firm look, clenching his fists.

He Yuzhu came to the frame and carefully looked at every detail on it. At the same time, he carefully recalled the knowledge about cars that he had heard in the later generations. After carefully looking at the frame, He Yuzhu said to Teacher Li Yang: "Teacher Li, our frame is currently rear-wheel drive. I suggest that we get a Willys Jeep to study it when we have a chance in the future. I remember that the Willys Jeep is a four-wheel drive. The rear-wheel drive is sufficient for normal roads, but after all, our country still has some roads with relatively poor conditions. The performance of four-wheel drive on poor roads is better."

"Team Leader He, if you hadn't mentioned it, I almost forgot about this. As long as we can solve the four-wheel drive problem, our car may have a chance to be used by the National Defense Forces!" Li Yang said excitedly.

"As long as we can really produce this car, it will definitely catch the attention of the National Defense Forces. You know, we are the only one in the country that makes off-road vehicles, and it seems that there is not even a car manufacturing plant in the city of Sijiu at present?" He Yuzhu said with full confidence.

"Team Leader He, according to the information I received, the First Automobile Accessories Factory in Sijiu City seemed to have started developing cars in February this year, and their factory's R&D capabilities are much stronger than our repair workshop. According to the information I have, it seems that the car they developed is almost successful?" Li Yang said embarrassedly.

"Really? Teacher Li, are you sure?" He Yuzhu asked anxiously after hearing what Teacher Li Yang said.

"Well, the news is true. The First Automobile Accessories Factory in Sijiu City produces carburetors, gasoline pumps, cylinder gaskets, automobile lights and other accessories. Moreover, they have received full support from the automobile and tractor major of Huaqing University, so their car should be able to roll off the production line soon." Teacher Li Yang told He Yuzhu all the news he knew.

He Yuzhu carefully recalled in his mind, and he had no memory of car production in Sijiu City in the 50s. The earliest memory of car production in Sijiu City was the production of 60 jeeps in the 212s. However, the cars that high-ranking officials rode in would definitely not be Red Flags. But Teacher Li Yang would not lie to himself. He could only say that this car produced by the factory near the First Automobile in Sijiu City was also copied from foreign cars, but it was obvious that the level of imitation was not up to standard and did not pass the national acceptance, so it was not produced on a large scale.

Thinking of this, He Yuzhu said confidently: "Teacher Li, don't worry. I feel that the car made by the First Automobile Accessories Factory in Sijiu City that you mentioned is probably a copy of a foreign brand, otherwise they couldn't have made it so quickly. You know, it took us almost two years to copy the Dodge car and we haven't solved all the problems. Don't worry about their copying situation. We just follow our own ideas and take it step by step. Sometimes walking fast doesn't necessarily mean you can get to the end. On the contrary, walking steadily is the key."

"Team Leader He, what you said makes sense. I'll get busy then." After saying that, Li Yang walked towards the office.

Looking at Li Yang's back, He Yuzhu had something to say. It seemed that he had to think of a solution. Otherwise, if the off-road vehicle was really developed, the superiors might give the production task to the First Automobile Accessories Factory in Sijiu City. Wouldn't it be like he had worked hard for two years to make wedding clothes for others? He Yuzhu fell into deep thought.
