Li Daguo returned home exhausted, and Qiao Wan helped her husband into the house.
She asked worriedly: "Old Li, those relatives at home said that you took out a large loan.
Longchang was really short of money, so I went directly to my dad.
When my father split up the family, the Longchang car dealership was given to us, and the rest of the family property was divided among the younger brothers and sisters.
Dad is not short of money. Let him bury his money in the cellar instead of letting him invest in our business."
Li Daguo waved his hand and said firmly: "My father-in-law allowed you to marry me, and he didn't beat up the mandarin duck because of the wrong family. I was grateful to my father-in-law for his open-mindedness.
But those uncles of your Qiao family have always looked down on me.
I am a man who stands upright and must do something to make these people who look down on others realize their mistakes.
Now the imperial court provides low-interest loans for diesel engine projects.
I have to work hard first and burn through all the loan money, but there is no result yet.
At that time, I will definitely ask my father-in-law for help."
When Qiao Wan heard her husband's assurance, she no longer worried.
She was afraid that her husband would become stubborn and refuse her father's help.
When Li Da was resting at home, he was still thinking about the structure of the car.
If the steam engine is replaced by a diesel engine, the structure of the car will be greatly changed. Except for a few structures such as the chassis and brakes, which only need slight adjustments, the rest of the structure is equivalent to designing from scratch.
They have already designed most of the car's structures and just need to assemble them into a car.
He went to bed after the ugly moment, and when he woke up in the morning, his eyes were red.
Qiao Wan wanted to give some advice, but she had done so in the past few days, but it had almost no effect, so she didn't speak again.
She just prayed in her heart that the project would succeed as soon as possible.
Li Da had a simple breakfast and took a car to the Longchang headquarters. His wife Qiao Wan sent the children to primary school.
The car stopped in front of the company. He looked at the car that was constantly emitting white smoke and black smoke. He sighed and said:
"I hope Mr. Jia will work harder and make breakthroughs in key technologies as soon as possible."
Li Daguo walked into the Longchanghao factory and was familiar with every plant and tree here.
A few years ago, there were not so many mechanical equipment available. He led the workers to knock out the cars bit by bit using hammers and wrenches.
He came to the R&D workshop and saw Jia Hang, the project chief engineer, leading a group of energetic young men around two model cars, one large and one small.
Of these two model cars, the smaller one looks very delicate.
It is to lower the chassis of the steam car, increase the internal space, remove the tall carriage and replace it with a low carriage.
The model of another vehicle is a heavy-duty carriage produced by Longchang a long time ago, with the horse in front replaced by a wheel.
This kind of tricycle is a truck designed by Chief Engineer Jia Hang based on the freight requirements and the existing technology of Longchang.
It can really be manufactured and pull more than ten tons of cargo without any problems.
Li Dagou is very well-informed, especially his father-in-law's strong network of connections.
He already knew part of the imperial court's plans, and the imperial court paid more attention to freight.
Li Dagou decided to develop two models, one is a high-end passenger car and the other is a truck.
His past experience made him deeply realize that only by closely following the court's policies can he develop and grow more easily.
Li Dagou looked at Chief Engineer Jia Hang's red eyes and said with concern: "Chief Engineer Jia, even if it is for the sake of our project, you should get more rest."
There is no trace of falsehood in his concern for Chief Engineer Jia Hang.
This is a talent he hired with a lot of money. It is no problem for him to fall ill himself. The company has experienced people to take over the job.
But Mr. Jia fell ill, and the entire project was stalled.
Jia Hang said firmly: "Sir Li also often stays up late. My body is younger and there is no problem in staying up.
I want to be worthy of Sir Li's salary and be conscientious in everything I do."
When Jia Hang was a child, his parents taught him that a drop of kindness should be repaid by a spring.
Sir Li offered him a sky-high salary, and he could only use his knowledge to repay him.
Jia Hang also wants the project to be successful, and the dividends he receives will allow him to gain a foothold in the capital.
Not only can you marry and have children in this big city, but you can also bring your parents over with no problem.
They exchanged polite words, but Li Daguo changed his mind and asked: "Is the diesel engine still unable to be installed in the car?"
As the deputy chief engineer of the automobile project, Li Dagou is mainly responsible for vehicle design, which is a job he is very familiar with.
Chief Engineer Jia Hang is responsible for designing a diesel engine suitable for vehicle use and coordinating the coordination between the diesel engine and other components.
He is indeed a capable person. Not long after he came to the project, he copied Professor Jiang Qing's diesel engine one by one.
But in the process of automobile integration, they encountered many problems.
Most of the small problems have been solved one by one, leaving only two big problems.
Li Daguo said with a solemn expression: "Chief Engineer Jia Hang, let's study these two problems again.
The problem that I have no idea about now is the steering of the car.
Professor Jiang Qing's technical authorization is very detailed. There are two systems for speed regulation of diesel engines and connected equipment.
The diesel input size is adjusted with the diesel engine gear, which can solve the problem of the car's forward speed.
But in addition to the diesel input size, the power of the diesel engine is adjusted.
To adjust through gears, the diesel engine needs to be disassembled.
This requires professional people to operate, and we are now going to simplify this process, even for people who know nothing about it.
It only requires simple operations to adjust the speed of the car, preferably with a reverse function.
The second problem is that the overall layout of the car, especially the smoke exhaust function, does not allow exhaust gas to affect the passengers in the car.
I have thought about this issue for a long time and already have some ideas."
Chief Engineer Jia Hang said in a brisk tone: "Sir Li, the first problem is difficult to solve. I have led the team in research and development for many days, but this problem has not been solved.
But I am also a teacher. When I got home from get off work yesterday, I was very worried when I thought about this problem.
I learned that my teacher, Professor Jiang Qing, had free time, so I immediately rushed to his home to ask for advice.
This chapter is not over yet, please click on the next page to continue reading! When the teacher heard this problem, he immediately gave me a solution.
The gear set inside the diesel engine is designed to facilitate the diesel engine to connect to more mechanical equipment.
The diesel engine we make is only for cars and does not require complicated gear sets.
Only a simple gear set is needed to change the direction and speed of the car through multi-stage gears.
After receiving the teacher's guidance, I returned to the dormitory and started designing the gearbox.
According to my knowledge, the multi-stage gear set has been designed, but I am still lacking in how to facilitate customer operation."
Li Da was overjoyed. He was indeed Professor Jiang Qing. Despite his reputation, he was indeed a true scholar. Professor Jiang Qing was able to clear up the problems that had troubled them for months with just a few words.
He asked in surprise: "It's good if you have an idea. Let's discuss it together."
Chief Engineer Jia Hang took out the gearbox he designed.
"After the test just now, the gearbox in my hand should be able to solve the problems we encountered.
The gearbox is the name given by my teacher. It is a machine composed of multiple gear sets.
The power output of the diesel engine remains unchanged, and the flywheel is connected to the power gear.
The gear set has multiple gears, representing the four gears of slow, medium, fast and reverse.
I have designed it up to this point, and now the problem is how to switch the complex gear set in a simple way."
Li Daguo fiddled with the gear set with his hands. He was thinking about how to solve the problem.
He suddenly thought of his son, who was in primary school and was now learning to ride a bicycle.
When the rear wheel of the bicycle is rotating, even if you stop pedaling, the rear wheel of the bicycle will not stop rotating.
The bicycle uses a ratchet to connect the main shaft and chain so that they do not have to maintain the same speed.
He looked at this gear set. The power gear could be separated from the gear set for a short time. By adjusting the position of the gear set, the power gear could mesh with other gear sets.
Li Dagou immediately drew a sketch on the paper and gave his suggestions.
Chief Engineer Jia Hang slapped his thigh and said excitedly: "Sir Li's method is very clever. We can completely adjust the position of each gear set through levers.
But in this case, a device must be installed to separate the power gear and the gear set before adjusting the position of the gear set, so that the gear set can move freely."
The two agreed that this idea was feasible. They immediately discussed the drawings of the gearbox, determined the details of the drawings, and asked the workers to manufacture the gearbox.
Chief Engineer Jia Hang put down his pencil and asked curiously: "Sir Li, you said you already have an idea for the second problem. What is your solution?"
Li Da confidently said: "We have been stuck with the original car structure.
In the original automobile, due to the large compartment and boiler pressure, the boiler needed to add water, fill the coal and exhaust smoke. In order to simplify the steam engine for automobiles, the automobile exhausts smoke through the front.
The amount of smoke produced by the diesel engine is not large. We can exhaust the smoke through the back and use the flue to dissipate part of the heat and reduce the pressure on the water cooling device.
Exhaust smoke from the rear of heavy vehicles so that it will not affect the passengers inside the vehicle."
Chief Engineer Jia Hang gave a thumbs up and believed Li Daguo's suggestion was feasible.
They finalized the final drawings of cars and trucks and began building the cars.
The factory has gone through nearly a month of hard work, constantly counterattacking and summarizing experience.
The cars and trucks produced by Longchang finally came off the production line.
Li Da said excitedly: "We succeeded. This is really not easy."
He and Chief Engineer Jia Hang personally drove the four-wheeled vehicle, and the shopkeeper of the Longchang was driving the three-wheeled truck behind them. They drove the two vehicles out of the factory.
The three-wheeled truck was also pulling a car.
Li Daguo said this was to prevent the car from having a mechanical failure midway because it was newly built, so that they could have new vehicles to drive.
As for the three-wheeled trucks, since the design direction is to make them solid, they use the simplest machinery.
Three-wheeled trucks have a simple structure and have a low probability of problems.
Even if a problem does occur, most faults can be solved with simple repairs.
These two cars hit the road, and their shapes are completely different from other vehicles.
Especially the wind-like speed of the two cars shocked everyone who saw them.
"Is this a new car from Longchang? The vehicle bears the trademark of Longchang."
"There have been rumors that the owner of the Longchang took out millions of taels of silver coins and invested heavily in the research and development of diesel-engine cars.
Many people said that the owner of Longchang was a fool and laughed at him.
Now it seems that the real fool is very obvious."
Wu Hongren was accompanying his cousin Wu Hongyi for dinner at a famous restaurant.
They sat by the window, which was Wu Hongyi's favorite seat, and could see the smoke of fireworks outside.
He is a cabinet minister, which is a very difficult position to fill.
If things are done well, it is the prime minister's credit; if things are not done well, the person who did it will take the blame.
Especially the Prime Minister who is under one person, as long as aspiring officials, everyone wants to experience it.
There is only one prime minister, but there are many cabinet ministers.
If you want to rise to the top, you must pull others down.
This results in cabinet ministers walking on thin ice when doing things, fearing that their competitors will find problems.
Wu Hongyi came to discuss matters with his cousin because the task he undertook was oil refining.
Emperor Su He promoted the development of diesel engines very hard.
There is a lot of local oil in the Nanyang region because of its rich oil reserves.
Diesel has become more widely used, and many chambers of commerce have begun to get involved in diesel smelting.
But in reality, diesel sales are very sluggish.
This shows Wu Hongyi's lack of ability.
Wu Hongren drank a glass of wine and said helplessly: "Third brother, our family's business firm has also invested a large amount of money into the oil refining industry.
I even used a cargo ship to bring 20,000 barrels of diesel and placed it in the Tianjin Port warehouse.
But now diesel cannot be sold because there are no machines that use diesel.
It’s really cheaper for people to buy oil for home use and to burn fires. It’s really cheaper to buy oil directly.”
This chapter is not finished yet, please click on the next page to continue reading the exciting content! When Wu Hongren said this, he also complained about Li Daguo, this kid is really incompetent.
Their chamber of commerce has already produced so much diesel fuel, but the Longchang car has not yet come out.
There are too few diesel engines in stock. Who would buy diesel?
While they were eating, they heard cheers coming from downstairs.
"It's so fast. This car is really fast."
"Holy shit, this car should be faster than the train."
"Everyone, please move out of the way and see the top speed of this car."
The two brothers Wu Hongyi and Wu Hongren were very curious and looked downstairs.
Only a silver-white vehicle was seen, speeding down the avenue downstairs at a very high speed.
The speed was extremely fast, and they could only see an afterimage passing by.
Then there was a slightly faster tricycle, with thick black smoke coming out from behind, and a car that had just passed on its body.
Wu Hongren didn't see clearly what this car looked like just now.
When he saw the vehicles in the tricycle, he blurted out: "The car on the Longchang runs so fast. This must be the result of Brother Li's successful development of a diesel engine car."
Diesel-engine cars are finally on the road, and our diesel has a market."
When Wu Hongren saw this situation, he was very excited.
The cooperation that was originally a win-win situation can continue.
Wu Hongyi set his sights on the three-wheeled truck. He believed that this humble truck was much more important than the four-wheeled truck.
Such a large steel four-wheel vehicle weighs at least two tons.
This three-wheeled truck can pull two tons of cargo and run very fast.
It is also a tricycle. The difficulty of operating the vehicle is similar to that of a bicycle, and it is more convenient for people with less knowledge to operate.
The three-wheel truck has a higher chassis and is not picky about roads. It can travel on asphalt roads, cement roads, and rural dirt roads, and its application range is wider.
As long as the load-carrying performance of this car is not too bad, it will definitely sell well.
