The atmosphere of the Qin people's festival is very strong. Especially after every household imitated Shangwen and pasted red paper. The whole Xianyang looks very festive. There are new highlights of traditional festivals. That's a lot of great sporting events.

The second year of junior high school is when the event is concentrated and unveiled. Racing, shooting, horseback riding, and more. People are coming out of their homes to watch these exciting events. Watching the game has become a new kind of program after the festival. Sporting events attract a lot of attention with their unique spectacle.

Racing, shooting, horseback riding. It's all about the military. Part of it is also related to the physique of the strong Qin people. But some of them are purely technical. For example, racing.

The cars are not very spectacular. Because, there have been some small carriage races before. Mostly some four-wheeled carriages. These carriages were a contest between the best chariot drivers in the city. Later, although there were also bicycles. But bicycles and horse-drawn carriages are simply not in the same order of magnitude. So the cycling separately requested the establishment of a special event. So. The spectacle of the car suddenly decreased a lot.

However, the race in the second year of junior high school attracted a lot of people at once. Because, this time there was a "big one".

The competition was first selected by each carriage and horse dealership, and in order to encourage people to participate, the first place prize was 10 gold. So, some of the horse-drawn riders were happy to participate. And some people in order to get the prize of ten gold. They also modified the carriages.

The purpose of the modification is to reduce the weight of the car as much as possible. For example, the number of wheels has been changed from four to two. Bicycle wheels are also used for both wheels. Because the weight can be greatly reduced. This modification had a great impact, and many people began to modify the carriage specifically to win the race.

Just when the eyes were focused on how to modify the carriage. A middle-aged man named Meng Bao participated. The difference is that his race car is made of a steam engine.

Meng Bao is a mechanical worker. He studied the mechanical side as if he were fascinated. He believed that horse-drawn carriages could not outrun trains, and that trains used steam engines. So, he built a small boiler equipment himself. Later, he modeled the tracks of a tractor and used them as running gear. From the production to the development of this big guy, he spent a full seven days of hard work. At the time of the Chinese New Year. He's all researching.

His race car used a small boiler equipment though. But it's still a huge "big one." "Black smoke came out of the tall chimney. The entire length of the car turned out to be two feet. It's almost a foot taller. Such a big guy drove up, booming. That's why. A lot of people were attracted to the game.

Meng Bao stood on the high racing car, his hands and feet were constantly busy operating, and the black smoke that came out of it smoked his face black. This big guy doesn't have a steering wheel. Some only have a lever. There are a total of four levers. When turning, stop one track, and then turn the other. Behind the car was also a small vehicle pulling coal. Meng Bao kept taking a shovel and adding some coal to the boiler.

Since this guy is just too heavy. His speed simply can't be raised. People can catch up with him as they circle the car. But Meng Bao didn't plan to win the race the first time. What he wants to declare is that the machine will eventually triumph over the horse.

Some carriages sped past him. As if laughing at the big one. People followed him curiously. After all, it's a machine moving again.

At that moment, a small car came up behind the big one. This car is also weird, it's a tricycle. The whole body is very lightweight. In some places, wooden planks are even used.

However, there were two large pillars in front of him, and Meng Bao knew that they were pistons.

"Hi. Are you also participating in the competition? "There was a little young man in the car.

"I can't hear what you're saying." Meng Bao shouted loudly.

"I said, are you coming to the competition?" The young ** shouted. The steam engine was loud. This made Meng Bao a little inaudible.

"Yes." Meng Bao replied simply.

The young man gave a thumbs up to indicate his efforts. Then walk away. The young man was driving an early car. The difference is that instead of gasoline, he uses diesel.

The discovery of the diesel engine was actually quite accidental. When it was discovered that the use of gunpowder to ignite the piston could propel the piston into motion, it was never studied further. The reason was that they could not find a reliable alternative to gunpowder. Because, under a certain pressure, gunpowder sometimes does not need to be specially ignited to explode. As a result, the experiment was abandoned.

But with the rapid development of the economy of the Qin State. Especially when there is a large-scale demand for asphalt. Huge quantities of gasoline, kerosene, diesel began to appear. The role of kerosene was discovered. Especially with the addition of a glass lampshade. The demand for kerosene began to become as big a demand as asphalt. But petrol and diesel are not very useful. These two are mainly used as fuel. But he burned just too fast. Or it is volatile and causes some accidents. During the transportation, the carriage was completely burned. Therefore, gasoline and diesel have always been disposed of as waste oil, except for military use. No one wants other commercial uses at all.

And at this time, that is, the young man just now. He is a chemistry student at Qinguo University. He took two courses at the same time. Qin's university curriculum is still not standardized. Students' semesters are often counted according to the amount of study and the results of research. If a student has made a great discovery in a certain field. Soon, he became a teacher of this.

Refineries in the north are worried about the growing backlog of gasoline and diesel. Because, these things are easy to explode, but no one wants these things. So, the student began to study gasoline and diesel.

At one time, he conducted a compression test on gasoline. He tried to see if he could produce a new substance through a compression test. But unfortunately, it didn't work out. But when it comes to diesel testing. When compressed. Suddenly, the gas plug was opened. This serendipitous discovery. To his surprise, after a series of tests, he found that the ignition point of diesel is lower than that of gasoline. This discovery does not address the usefulness of diesel. When he was in mechanical engineering. The teacher gave him a lot of inspiration when he was explaining the principle of the steam engine. That is to use the process of compression to ignite diesel fuel to complete a mechanical action. So, he began to conceive. Study. Eventually, the diesel internal combustion engine was developed.
