On December 15th, Sister Zhang Xuan set off for Jiangwei under the escort of Yang Jianguo and Han Meng.
In this way, only the old couple and their son were left in the Zhang family.
But this is only temporary. A year later, Zhang Zhiyuan and his family will also move to Jiangwei.
After seeing Zhang Xuan off at the train station, Wan Feng and Han Guangjia also took the train back to Heihe to continue the test.
A month passed quickly.
During this month, the team underwent ice and snow test drives in various ice and snow climates, including power, body rigidity, chassis suspension and transmission performance.
Finally, tests such as fixed circle test, ABS runway, ice slalom, and cold start were carried out.
Although it is excellent in all aspects, many minor problems were found in the vehicle in icy and snowy climates.
These minor problems should be solved on the spot if they can be solved on the spot. If conditions do not allow them to be solved, they should be returned to the headquarters for modification.
After the ice and snow test drive is completed, we will move to Mohe for the final high-altitude test.
Mohe is the northernmost part of China, where the lowest temperature can reach minus 40 degrees Celsius.
The daytime temperature is usually between 20 and 30 degrees below zero. There is no better place in China to conduct high-altitude cold tests than here.
The test team set out from Heihe and finally arrived in Mohe via the Humata River after two days.
Mohe County is not large, with a permanent population of about 60,000 to 70,000 people, and the entire county is encompassed by one street.
The team has completed the ice and snow test drive in Heihe, and went to Mohe mainly to conduct high-altitude cold tests.
Low temperature cold start test, low temperature air conditioning system test, high cold durability test, ESP test and low temperature braking system test, etc.
The first is a cold start test twice a day, morning and evening.
Vehicles from the 1990s had to spend a night in temperatures of -30 to -40 degrees Celsius, and it was very difficult to start them successfully in the morning within the limit of three starts within four seconds.
But these cars actually did it. Although none of them started successfully on the first try, almost all of them started successfully within three times.
This is thanks to the reasonable design of the engine and the high-power battery designed by Yang Li's team.
Although Yang Li's team has not yet made a real breakthrough in lithium batteries, because they have sufficient manpower, they have allocated some people to improve traditional lead-acid batteries.
Now the fleet uses their batteries.
After a successful cold start, the vehicle needs to drive out directly without warming up, and continuously complete acceleration and deceleration in different speed ranges, simulating the stop-and-go road conditions under normal driving conditions, as well as the vehicle's acceleration performance after the red light at the intersection turns green.
Strictly speaking, this test is a bit boring. On the test section, you start at full throttle in first gear, then slow down to idle, shift to second gear and drive at full throttle, then slow down to idle, shift to third gear and drive at full throttle... then shift to fifth gear and drive at full throttle, then slow down to idle.
During the whole process, the common rail pressure, filter inlet pressure, oil pump inlet pressure, injection return pressure, injection volume, oil pump inlet temperature, filter inlet temperature and injection return temperature are tested under low temperature environment.
These tests also take more than ten days to test.
Wan Feng accompanied the convoy in and out every day, and his hands were frozen.
Another half a month later, the vehicle test was finally completed.
At this point, their cars have completed high-temperature, high-altitude and high-cold tests, and each car has traveled no less than 200,000 kilometers.
This driving distance cannot be compared with the hundreds of thousands of kilometers tested in later vehicle tests.
Wan Feng discussed with the masters of the test team and decided to go home after confirming that the test requirements were basically met and there was nothing else to do.
On January 18, 1991, Wan Feng announced his return home!
The convoy was full of jubilation.
This is more than ten days ahead of schedule.
The journey home is much easier. There is no need to take tests or rush, just keep running back.
After the car arrived at Heihe, Wan Feng bought another ten tons of oil to transport it.
After getting off the car and testing it, should I buy a tanker or build one myself?
In an era without gas stations, it is always safer to bring your own gas.
Five days later, on the eighth day of the twelfth lunar month, the test team finally returned to Jiangwei.
After submitting various test data to the responsible departments, the test team prepared to go on vacation.
During their vacation, Wan Feng gave their entire team a first-prize bonus of 800,000 yuan.
I went out with him once and realized how hard it is to test drive outside.
It would be fine if the vehicle didn't break down, but if it did, it would be fine if the weather was good, but it would be a real pain if the weather was bad.
Therefore, they deserved the first prize.
After returning home, Wan Feng rested well for two days before going to work.
Even though he is physically strong, he can't stand being outside for the past two months.
Wan Feng was away from home and did not attend this year's annual meeting. The group issued a total of nearly 30 million yuan in various bonuses this year.
There are a lot of first prizes this year, whether it is Chen Dao's 90CC motorcycle or Yimeng Wenguanghua's car; from the Chinese character display of Gu Hongzhong's team to the 1M memory of Wang Wencheng's team, plus the nine-axis machine tool of Li Da's team, there are about eight or nine first prizes given out.
Wan Feng doesn't care how much bonus he gives out. The more he gives out, the more patents his company has, and these will all be money in the future.
Zhu Yong showed Wan Feng the detailed income and expenditure of Nanwan Group for the whole of last year.
In the past 90 years, the group's net profit increased by 100% over the previous year, reaching 1.16 billion yuan.
This is the first time since the group was founded that its profit has exceeded 1 billion yuan.
Among them, the motorcycle department is still the largest, including the Dongguan branch.
The company produced 900,000 engines throughout the year, of which 660,000 were assembled into complete vehicles and 240,000 were sold as engines.
Motorcycles alone generated 800 million yuan in profits for the group.
The machine tool department also sold dozens of high-end machine tools this year, earning a profit of about 100 million yuan.
The Huaguang Electronics Department's learning machines and pagers also brought in more than 100 million yuan in profits.
Plus the income from accessories.
This is the group's revenue, and below is the group's expenditure.
The expenditure items include the railway station, Dongshan Community Phase II, shoe factory, Shanghai’s land and engineering investment, as well as the group’s annual meeting bonuses and scientific experiments.
Among them, the investment in scientific research reached 350 million yuan, plus other investments reached 150 million yuan.
Total expenditure is 500 million yuan
After adding and subtracting, the group's surplus this year is 660 million yuan.
Wan Feng sighed. The current expenditure on scientific research is nearly 400 million yuan. In ten years, the annual investment in scientific research will reach several billion yuan.
Under normal circumstances, an enterprise's scientific research investment is 10% of its revenue, and at most no more than 20%.
How much is this?
More than thirty percent!
