Countercurrent 1982

Chapter 1928 Real Vehicle Test
This is definitely the most aggrieved car Duan Yun has ever made.

Duan Yun's height is 1.7 meters five, sitting in the driver's seat of the prototype car, the distance between the top of his head and the compartment is only a finger's width, and it feels a bit bumpy.

But fortunately, the seat can be adjusted up and down. Generally speaking, there is no problem in driving a car while sitting here.

And this is also Duan Yun's feeling after getting used to Santana and Volvo cars, because he has never sat in a mini car before, and the cab is indeed a bit crude, except for the instrument panel steering wheel, speedometer and gear knob, there is nothing For any other interior, there are two spaces to the left of the main console, which should be the place to put the car recorder and air conditioner.

But it is a prototype car after all, and it is normal that some parts are not installed. Moreover, with Tianyin Group's electronic technology, equipment such as car air conditioners and tape recorders can be easily made and mass-produced. The problem, the key is the three major parts of the car.

"Can you drive out?" Duan Yun looked a little bit at the position where the fuel gauge box was still 1/3 from bottoming out, so he turned his head and asked Chen Qiao.

"Mr. Duan, it's okay to drive out, but there's no safety equipment installed here, just a seat belt..." Chen Qiao immediately showed embarrassment when he heard this.

Because this car is still in the stage of indoor testing, although it can be driven out, it is generally not suitable for people to drive in it for a long time, and Chen Qiao also knows that his boss is famous for "Desperate Saburo" ", when Duan Yun sat in the Volvo car safety crash test when he watched the live TV broadcast, he was indeed shocked into a cold sweat.

"It's okay, I'll drive slowly." Duan Yun glanced at Chen Qiao, then turned the key of the engine, and the engine was quickly started.

And Chen Qiao hurriedly asked someone to open the aisle, opened the door of the testing workshop at the same time, and followed behind the car.

"Da da da!" With the sound of the engine, Duan Yun shifted into first gear, released the foot brake, and the car slowly drove out of the workshop.

I have to say that this may be the lowest-performance car that Duan Yun has ever driven. It may be because the engine's shock absorption is not in place, so the three-cylinder engine shakes a bit. , the hood of the front part of the car can see the shaking visible to the naked eye.

But in fact, there should be no problem with the engine of this car, because I heard from Chen Qiao before that these prototype cars have been tested continuously for more than a week, and there is no problem. In the process of continuous improvement, it is estimated that after adding some simple accessories such as pads, the situation will be much better.

In fact, the main reason why Duan Yun is so sensitive is that the cars he rode in his previous life were far more advanced than the cars of this era. And Volvo, the same problem exists, but Santana and Volvo are four-cylinder engines, so the jitter is much smaller.

However, as the first mini car developed and produced by Tianyin Group, it is obviously a bit "luxury" to equip it with a four-cylinder engine, and the Xiali produced in the 8s and 90s is equipped with a 376-cylinder code-named "TJ3Q". At the same time, the Alto of that era used the F8B engine, which was also a 3-cylinder.

The most direct advantage of using a three-cylinder engine is that the technical difficulty and cost are relatively low, and the related technology is relatively mature. Therefore, as a model for initial research, a practical research and development plan must be available.

Later, because of congenital defects such as loud noise and jitter, the 3-cylinder engine began to be gradually abandoned by car companies.

Although Duan Yun feels that the jitter is a bit big, in fact, the 212 Jeep he drove in the early years was also jittery, but the 212 body is relatively large, and it is a mature product, so it is not as obvious as this sample car. .

After the vehicle drove out of the workshop, Duan Yun went directly to the outdoor testing site.

Thanks to the support of the SY Municipal Government, Duan Yun's outdoor testing site covers an area of ​​more than 200 acres. From the end of last year to this year, Duan Yun has invested a total of more than 6000 million yuan to build various facilities for testing the performance of cars in the agency. There are roads and slopes, and there are rivers and sandy areas that simulate field conditions. No matter in terms of scale or function, this R&D center is regarded as the largest in China. Compared with Changchun FAW's automobile test site, the facilities are more comprehensive. And the footprint is 1/3 larger.

The prototype car with only 35 horsepower has no problem driving on flat ground, and this car seems to have done a certain degree of shock absorption. bumps.

However, when entering the slope test, the 15-degree slope was already a bit strenuous, the engine speed was fast, and the sound of the engine was already a bit noisy, but it was basically able to pass smoothly. However, when entering the 30-degree slope test, the front wheels After entering the uphill, no matter how much Duan Yun stepped on the accelerator, the prototype car did not climb up in the end.

In fact, as far as ordinary domestic gasoline vehicles are concerned, it is very difficult to climb uphills of 30 degrees. Some imported cars may be able to, but it is difficult for domestic cars to continue climbing such high slopes. Both power and torque requirements are very high.

But even so, after a round of testing, Duan Yun is basically satisfied with this prototype car, because this kind of mini car is originally positioned as a low-end, cheap civilian car, and it is usually used for transportation in urban areas at most, and few people go there. To drive this kind of car for a long trip, as long as the three indicators of cheapness, durability and fuel efficiency can be guaranteed, it is already considered a qualified product.

"The power is almost like this, but it's enough..." After getting off the car, Duan Yun patted the roof of the sample car, and said to Chen Qiao: "This car still needs to be polished, the body structure must be strong, but it cannot It is too heavy, because it is related to the issue of fuel economy, and the cost of the whole vehicle is to be reduced as much as possible, and it is necessary to have the ability to make this kind of car put into production and market by the middle of next year."

In fact, Duan Yun knew in his heart that according to the current situation, if this car really wants to surpass the performance and price of Alto cars of the same level, then it will definitely need a longer polishing time, but there is not much time left for Duan Yun. Because he also plans to develop a sedan that will compete with Tianjin Xiali in the next step. He wants to gain a firm foothold in the domestic auto market before the development of international auto technology to the next generation.
