After a while, Deputy Director Liu Mingzeng and Wei Dongfeng of the institute came over. The two reported on their recent work, especially Wei Dongfeng's research on agricultural vehicles. With the cooperation of Shandong University, the research on gearboxes has made great progress and the principles have been figured out. However, there is still a big gap in service life compared with foreign imports. The key lies in the materials. If the materials do not pass the test, they will not be used after production.
However, Shandong University and the School of Materials Science are already working on the project. They have a prototype gearbox, so it is only a matter of time before they succeed.
"Can we make a car that doesn't need a gearbox?"
"How can that be? It's unsafe and the fuel consumption is extremely high."
"What I mean is this: let's build a tricycle about two meters long with a transport capacity of no more than 500 kilograms. We can use a gasoline engine to drive a generator, which in turn drives an electric motor, with a battery installed in the middle. I know our generator and electric motor technology is quite advanced, so can we eliminate the need for a complicated gearbox?"
"In theory, it is possible, but no one has done this internationally or domestically," said Wang Cuncai.
"I don't understand the specific theory. How about we try to study it first? What if the trial production is successful?"
"I think it's a good idea. Let's make a small tricycle first. Once Shandong Province has developed the gearbox, we can then work on a bigger car."
"We can use a 1.4-horsepower gasoline engine to drive a 1-kilowatt generator with a 72-volt 100-mAh lead-acid battery in the middle and an 800-watt electric motor. How about we give it a try?" Wei Dongfeng widened his eyes and said happily.
"I think we can give it a try." Liu Mingzeng also said.
"Then let's try it. Do we have these things here? Yes, then let's start a verification. However, Wei Dongfeng, you take a few people to do a good calculation and strive for a good data match!"
"Okay, don't worry!"
At noon, Sun Zongyuan had lunch in the research institute. Three directors, several R&D department heads and Xu Rui sat around the table together. No one was reserved because of Sun Zongyuan's presence. Instead, their voices became louder as they argued about technical issues.
Sun Zongyuan likes this kind of serious atmosphere. It’s not an officialdom, so there aren’t so many rules.
The materials of the Mechanical Research Institute are relatively complete. If there is anything missing, they can just call the regional machinery factory and have it delivered. Of course, Sun Zongyuan is unwilling to take the machinery factory's things for free and requires the institute to pay the price. Feelings are feelings and business is business, they are two different matters.
Sun Zongyu went to work at the township government in the morning. There had been no major events recently and the weather was very hot, so there were fewer people coming from above.
I went to the institute for lunch at noon, and Xu Rui accompanied me. Xu Rui also brought a bottle of peanut chili sauce from home and spread it on the steamed buns. It was so delicious.
Zheng Chunyan's food research laboratory moved to the meat processing plant, not far from the research institute. Xu Rui called her over, and the three of them started researching chili sauce together.
Zheng Chunyan found a pancake, spread some chili sauce on it, tasted it carefully, and said loudly that it was delicious. After taking a sip of water, she told him the ingredients of the chili sauce.
"Engineer Zheng, can we make a few more chili sauces based on this flavor profile, suitable for different tastes? You can use peanuts, soybeans, beef, etc."
"I think I need to research your grandmother's cooking method, and then learn more about the flavors and recipes of different people. After comparing them, I can select chili sauces that suit different tastes."
"Okay, Xu Rui will allocate 10,000 yuan of research and development funds to Sister Zheng first. If it's not enough, you can just ask Xu Rui for more. In mid-October, I want to take a few bottles of chili sauce to the Canton Fair to try my luck."
"Okay, Mayor Sun, I promise to complete the task!"
"By the way, didn't we make some boiled water from cans a few days ago for disaster relief? There's a Daqing Mountain in the northwest of Honghua Township, and at the foot of it is a Tiger Back Spring that never dries up. People often go there to drink the water, and it's said to have longevity properties. Do you have time to test some of the water to see if there are any special ingredients?"
"You want to build a mineral water factory?"
"If I have this idea, I have to see if the ingredients are qualified first."
"We don't have all the testing equipment here. We can send it to the Provincial Institute of Geology and Mineral Resources for testing. They can issue a formal test report."
"Okay, go ahead and do it."
Three days later, a tricycle was parked in front of the institute's office. Sun Zongyuan followed Wang Cuncai, Liu Mingzeng and Wei Dongfeng to look at the appearance of the vehicle.
This tricycle uses a motorcycle-style steering structure and is divided into two parts. The front part is the driving part. A 1.4-horsepower gasoline engine, a generator, a battery and an electric motor are stuffed under the seat. The seat is a makeshift wooden board with a sponge cushion covered with cloth. The back should be the loading part. It is a bare chassis frame with no carriage installed yet. There is a transmission chain under the frame.
There are three rubber wheels that are 40 centimeters high, and the front to back length is about two meters.
Wei Dongfeng sat on it, used a pull rope to start the gasoline engine, then turned the handlebars to power the electric motor, and the car started.
All the onlookers applauded and welcomed him!
Several people took turns driving for a while, then laid wooden boards on the chassis of the car. When one person got on first, the car still ran easily. When another person got on, the car could not run fast. When three people got on, the car could not move at all.
The car stopped and everyone sat in the small conference room, talking about some of the problems with the tricycle. Sun Zongyuan listened to everyone's speeches, thought for a while, and said:
"As you all saw just now, our first prototype car is running! This is a major victory! I sincerely thank you all!"
