Liu Biao really picked up the treasure, no one expected that a small county town that was not even famous in the province, and it is estimated that most people in Yanbei Province did not know that there would be such a good mechanical genius in the small county.

The diesel engine is a machine invented by the German Rudolf Diesel to obtain power. Compared with gasoline engines, its advantages are obvious, that is, high torque and good economy.

The fuel used in diesel engine is diesel, which has a greater viscosity than gasoline and is not easy to evaporate, but its autoignition temperature is lower than that of gasoline, so the formation and ignition of combustible mixture are different from gasoline engines.

The main difference is that the mixture in the cylinders of a diesel engine is compression-ignited, rather than ignited. When the diesel engine is working, the air enters the cylinder, and when the air in the cylinder is compressed to the end, the temperature can reach 500-700 °C, and the pressure can reach 40-50 atmospheres.

When the piston is close to the top dead center, the fuel supply system and the fuel injector inject fuel into the cylinder combustion chamber at extremely high pressure in a very short time, the diesel oil forms fine oil particles, mixed with the air of high pressure and high temperature, the combustible mixture burns by itself, violently expands to produce explosive force, and pushes the piston down to do work, at this time the temperature can reach 1900-2000 °C, the pressure can reach 60-100 atmospheres, and the torque generated is very large, so the diesel engine is widely used in large diesel equipment.

For example, large diesel engine generator sets, power sources for large and heavy-duty vehicles. Such as locomotives, large mine carts, large lifting equipment, tank engines, ship engines, etc.

Compared with gasoline engines, diesel engines have significantly better thermal efficiency and economy. Because the fuel supply system is simple, its reliability and safety are much higher than those of gasoline engines.

Of course, the diesel engine is not good in all aspects, for example, due to its high working pressure, many components must have relatively high strength and rigidity. So generally speaking, diesel engines are relatively large and bulky.

Diesel engines with excellent performance have high requirements for the manufacturing accuracy of fuel injection pumps and fuel injectors, so the manufacturing cost is very high.

In addition, because diesel is not easy to evaporate, it is not easy to start in winter; The working method is rough, so the noise is loud, the vibration is large, and the emission of soot and particles (that is, the PM, which everyone knows now) is more serious, so it is very popular with cars.

However, Wang Yong knows that with the progress of science and technology in later generations, diesel engines because of their advantages, especially the new development of small high-speed diesel engines, and the application of some advanced technologies, such as electronically controlled direct injection, turbocharging, common rail, intercooling, etc., the shortcomings of diesel engines have been well improved and solved, especially in terms of energy saving and carbon dioxide emissions, which are "green engines" that cannot be replaced by other thermal engines, including gasoline engines.

Of course, Yang Daqi is just a genius, not a madman, he is just half a step ahead of this era. The common rail technology he invented will make all diesel engines on the market a big step behind the obsolete products.

The common rail injection fuel supply system is composed of a high-pressure oil pump, a common oil supply pipe, an injector, an electronic control unit (ECU) and some pipeline pressure sensors, and each injector in the system is connected to the public oil supply pipe through its own high-pressure oil pipe, and the public oil supply pipe plays a role in hydraulic pressure storage for the fuel injector.

When working, the high-pressure oil pump delivers fuel to the public oil supply pipe at high pressure, and the high-pressure oil pump, pressure sensor and ECU form a closed-loop work to achieve accurate control of the oil pressure in the public oil supply pipe, which completely changes the phenomenon that the oil supply pressure changes with the engine speed.

Of course, at this stage, the cost of this diesel engine is bound to be much higher than that of the diesel engine of traditional technology, but from the perspective of future market prospects, this diesel engine is the real darling.

Later generations of hybrids, or simply diesel-engined cars, almost all used this technology. It can be said that as long as they get the patent of this technology in their hands, even if the factory does nothing, the three partners will be able to make them billionaires just by relying on royalties.

Therefore, Wang Yong had no objection to Liu Biao's statement that he had picked up a treasure. In fact, it was not only the treasure that was found, but a cornucopia that was picked up.

With Liu Biao involved, soon the process of their new business accelerated. In recent years, because of the good relationship between Liu Biao and Wang Hai and Wang Yong's father and son, coupled with his own connections, it can be said that in Longcheng County, no matter where he goes in Hong Kong City, he is a well-known big man.

Such a big man wants to contract the agricultural machinery station in the county that can't even pay wages, and the relevant departments in the county are too late, how can they not agree?

can get rid of such a big burden that gives them a headache every year, and they are willing to send a pennant to Liu Biao. So things went very smoothly, and Wang Yong couldn't believe it.

Within a week, the farm machinery station changed hands. It has become a joint stock limited liability company with Liu Biao, Pan Zhixin, and Yang Daqi.

The general manager of the company is Liu Biao, the chief engineer is of course Yang Daqi, and Pan Zhixin has become the director of the workshop, who is responsible for organizing production.

It didn't take long for their patent applications to be approved in dozens of major countries, including China, and before the renovation of their production workshops was completed, large companies and large enterprises from more than 40 countries around the world came to the door to seek cooperation.

Under Wang Yong's prompting, they wielded the patent stick to kill all sides, and a "huge amount" of foreign exchange continued to be remitted to the company's account, making their company an instant hit and becoming a world-renowned engine manufacturer.

But that was later, and now Wang Yong didn't expect it to be so far. He just reminded the three excited partners to find a professional company to register the patent first, and then he was busy persuading his father to go.

In rural areas, the traffic conditions are very poor, and it will take more than ten years for the project to start in later generations. A dirt road with water, as soon as it rains, the road will be waterlogged, not to mention driving, even after people walk by, it is possible to trap.

There are also no buses in the countryside, and even short shuttles that can be taken almost a few steps can be taken in later generations. Wang Yong: If Wangjiazhuang where they are located wants to go to the county or the city, they can only go to the township and take a car.

The daily shuttle bus to the city and the county departs from the county or city in the morning, and then goes back to the township and is done.

So it's not easy for people in the village to go outside. Fortunately, there are not many rural people who go out to do errands. Generally speaking, the car is not too crowded, at least not up to the level of later generations.

In order to improve the travel conditions of rural villagers, the county responded to the call of the higher authorities and encouraged those who can afford to buy passenger cars for passenger transportation. That's a lot of preferential conditions.

What kind of oil supplement and the like are all small favors and small favors, don't mention it, the most exciting thing for Wang Yong is that he doesn't even charge any fees!

As for the use of the line fee of the largest head, there is not a point, and it is used in vain! Other value-added tax, urban construction tax, education surcharge, local education surcharge, and personal income tax are all not required.

If this kind of good thing is in the future generations, I am afraid that those big truck drivers who run individual transport will go crazy! But in this day and age, it's not who can afford to buy a passenger car worth hundreds of thousands.

So as the richest man in Longcheng County, Wang Hai was the first to be named. The county appointed Comrade Qin Lang to come to Wang Hai in person with a list of all the routes, and strive to make him choose to operate a line, which is also a political achievement of the county, isn't it?

But Wang Hai is busy working every day now, and his feet don't touch the ground, how can he have time to think about this? Soaking in the farm every day, the farm is still too busy, and he simply refuses the business that he thinks is not cost-effective.

Spend two or three hundred thousand yuan to buy a shuttle bus, and then you have to hire a driver to operate it for a few yuan or even a few cents per ticket, so you have to stare at that month to earn it back? Isn't it cost-effective at all? Maybe you have to lose money, who would be stupid to do this kind of business?

Qin Lang also thinks that in today's economic situation, this kind of thing is really thankless. After he learned about the situation, he easily came to the conclusion that this business was really losing money!

In these days, who would be willing to spend a few dollars to take a car to the county and the city? How many people have never been to the county in their lifetime, let alone the city.

Seeing that Wang Hai couldn't make sense, he simply didn't persuade him, and ran home with the driver Wang Xing, and asked Wang Yong to prepare lunch for him when he entered the door, and joked that he was here to send him money.

As a result, after Wang Yong knew his intention, he stretched out his slap without saying a word.

"Five, our family wants five lines first!"

Qin Lang is stupid! Wang Hai, who came back with him, was also stupid!

"It's a fool not to do such a good thing! It's still Uncle Qin, it's a good thing, and you know that you're thinking about us. Don't worry, what do you want to eat at noon today, you say, I'll do it for you without saying a word! ”

Qin Lang and Wang Hai, who knew Wang Yong's temper and personality quite well, immediately fell silent, this kid is definitely the master who doesn't see rabbits and doesn't scatter eagles, so he won't do anything that is not beneficial?

It is unprecedented for him to take the initiative to ask for cooking, needless to say, this matter of passenger transportation must have a head, a big head!

Now people just don't realize this because of their own knowledge. In fact, in the later generations, there is no one who does not know that running transportation can make money, whether it is freight or passenger transportation, it is a proper and profitable business.

Of course, after more and more private cars, the speed of making money for passenger shuttles has decreased significantly. However, because many passenger dedicated lines do not have any additional costs during this period, they still enjoy the country's fuel subsidies and the like, and they can still make a lot of money.

Some people in the industry once calculated an account, a special line from the countryside to the county seat, two trips a day. On average, I can collect five or six hundred yuan a day! Remove about 100 fuel money, about 100 driver salaries, and the rest is the owner of the car, and there are almost no other expenses.

I was in a daze all day in this class, and today I suddenly realized that the Mid-Autumn Festival was coming soon! The house is here to wish everyone a happy Mid-Autumn Festival and all the best in advance!
