Judging from the statistics of the Ministry of Household Affairs, replanting was also very timely, and drought-resistant crops such as corn and potatoes that had been arranged before were able to withstand the drought with the help of motorized wells.

Summer has already entered in April, and after the drought-resistant replanting work was completed, Su You felt that it was time for the capital to start fighting again.

Mou Zhuangzi in the Su family faces the Capital University across the lake and is very close to each other by water. Su You introduced Meishan lotus root in Liuyan Lake. Now there is a green lotus leaf in the bay outside Zhuangzi, and many fist-shaped lotus roots have grown there.

Lei has become a popular place for teachers and students of the college to visit.

Today Zhuangzi came up with a group of experts, and they all wanted to do an experiment together.

Zhang Xiangzhong, Chen Zhaoming, Su Xiaomei, Su You, chair, flat jar.

There are also Shi Wei and Colander who came to visit relatives.

There is a piece of equipment in the courtyard of the farm, which is a stainless steel poke, with a stainless steel barrel connected to two welding parts.

One of them is the fuel injector, which is connected to the gasoline barrel through a pipe.

The other is the spark plug, connected to the battery.

There are also a bunch of bits and pieces on the stainless steel barrel, such as pressure gauges, pressurizers, pistons, safety rafts, etc.

The test to be conducted today is to demonstrate the feasibility of the gasoline engine.

Everyone stayed away from the stainless steel bucket fixed on the iron shelf, and the chairs and flat cans were responsible for the actual operations.

The spark plug that strikes the electric spark is connected to an oscillator composed of a coil and a capacitor. The current oscillation is used to convert the electric potential of the electrode of the spark plug in turn, and the coil is used to convert low voltage into high voltage, allowing the spark plug to continuously produce electric sparks.

After the connection is completed, the flat tank closes the switch, and Chen Wu presses the oil inlet switch.

"Bang!" The stainless steel barrel made a loud noise, and the entire iron frame shook violently, and then returned to calm.

"Also——" Both the chair and the flat jar jumped up excitedly: "Success!"

"Yeah!" Colander also jumped up with his two brothers.

Su You smiled and touched the head of the colander: "You understand what you are doing?"

The colander said: "If you succeed, daddy will celebrate. There will be something delicious again today! Also——"

"Hahahaha..." Su You laughed happily: "To put it this way, it's not wrong that there is no colander!"

After laughing, Su You looked at Chen Zhaoming: "This is the big topic of the School of Physics. How about it? Can the internal combustion engine project be approved?"

Chen Zhaoming smiled and said: "The principle has passed the test, but I guess there will be a long way to go before we can realize the four-stroke internal combustion engine that my brother mentioned."

Su You is a bit shameless. Logically speaking, Chen Zhaoming is older than him and wants him, but who calls him the younger sister's husband? Therefore, Su You has always shown his brother-in-law in front of Bachelor Chen, and he doesn't want to be called his brother-in-law.

His brother.

Pulling Zhang Xiangzhong over, Su You said: "Spark plug, look for this guy. His electric furnace has been successful. The temperature has exceeded the two thousand mark. Now it can smelt vaguely five types of metals that are resistant to high temperatures and corrosion. The rest

You just have to explore.”

The flat can and chair had already come over, holding a record book in their hands: "The pressure gauge showed that the explosion reached 18.5 standard atmospheres."

The chair said: "This principle is quite similar to the principle of a machine gun. Can explosives be used to achieve this process?"

Su You smiled and said: "Chair, don't make trouble! Even if it can be realized in principle, how much material and labor costs will it cost? The purpose of this project is to solve the problem of waste of a large amount of crude oil processing products."

"If this project is successful, the gasoline that is being thrown away today and the diesel that can only be used to wash workpieces will be put to great use."

Chen Zhaoming shook his head: "See how proud my brother is, let's try compression ignition again."

Compression ignition must be replaced by diesel. Because it is a test, the four-stroke is simplified into two processes of fuel injection and pressurization.

Today's test is to win if the mixed diesel gas can be compression ignited, but it is too difficult to inject fuel under high pressure. It must be injected first and then pressurized.

So the stainless steel piston jar was connected to a pot camel machine, and the power of the pot camel machine was used to drive the piston movement and repeatedly pressurize the cylinder.

After getting ready, everyone moved away again, and the flat tank pressed the oil inlet valve while the piston was moving.

You can see that the crank connecting rod pressing down the piston clearly felt a resistance, followed by a "bang" sound.

This time the explosion in the barrel was more severe than that of gasoline, and the pressure safety bolt on the stainless steel piston tank was blown up into the sky with a "whoosh" sound.

Chen Zhaoming suddenly woke up and slapped his thigh suddenly: "Oh, brother, I made a mistake!"

Did I misunderstand you?! I came from time-travelling. Do you know that you dare to say that I mistook you?!

Seeing the injustice on Su You's face, Chen Zhaoming quickly said: "I have a better plan!"

"Huh?" Su You laughed as if he had seen a ghost. He was really angry. Are you kidding me?

Chen Zhaoming pointed to the stainless steel tank in the distance: "The current difficulties in internal combustion engines are one is ignition and the other is mixing oil and gas, right?"

"Ah, yes..."

"Since we have coal gas now, if we change the mixed gas to coal gas, won't it be much easier?"

"Eh? Wait...you need to use a spark plug to ignite the gas? Isn't it easy?"

"Why use a spark plug to ignite? Gas can also be compressed. If gas compression and diesel compression ignition are combined..."

"That's right!" Zhang Xiangzhong also reacted: "In this way, you only need to inject a little bit of diesel to ignite the mixed gas through compression ignition, achieving the effect we have always wanted to achieve!"

"Wait... wait!" Su You was confused by Chen Zhaoming's novel ideas: "There is something wrong with such opportunistic thinking!"

"what is the problem?"

"This... this gas is not easy to carry..."

"Why carry it?"

"Because...because..."

Damn it, are you saying that it’s because my goal is to invent cars, tractors, tanks, and warships?

The younger sister couldn't bear to see Su You's deflated look: "Brother, haven't you always taught us that in science and engineering, if you want to solve existing problems, then think of ways to solve good or bad problems..."

"Hi!" Su You suddenly realized: "My little sister is right! Change it! Immediately change it to a gas internal combustion engine project! The difficulty of the internal combustion engine will be greatly reduced, which is worth celebrating!"

"Yes!" The colander was waiting for this moment: "Success! Daddy, go cook!"

"Get off daddy's back first!" Shi Wei scolded angrily from the side.

Su You didn't care, at least he could still carry it now: "What do you want to eat with the colander?"

"Eat hot pot! French fries! Boiled meat slices!"

"Why eat hot pot when it's so hot? You can't fry the French fries if they're frozen. Boiled fish is fine!"

"Then boil the fish!" The colander is not picky.

Mouzhuangzi in the Su family was one of the first families to use gas in the Song Dynasty.

Coal gas development was originally a branch of chemical industry developed by Shi Fu. Its earliest purpose was to solve the problem of combustion temperature of steel-making furnaces and the utilization of coking by-products.

Nowadays, in many coal and iron industrial bases, large amounts of coal gas can be produced. In addition to meeting the needs of chemical industry, the surplus is transported through pipelines and used as fuel for street lamps and factory canteens.

Su You used the public benefit for private purposes and built a gas plant in the Capital University. It was nominally to meet the needs of scientific research and teachers and students' life in the Capital University. Then, in the name of the gas cross-river transmission project, the gas was connected through pipelines from the bottom of Liuyan Lake.

Come up to Sujiazhuangzi in Zhongmu.

The reason is very good. The Sujiazhuang Konjac Gum Film Experimental Greenhouse needs to burn gas in winter to provide carbon dioxide for plants to grow.

The peppers on Zhuangzi are tender and still green. Two years of targeted cultivation with colchicine has made the peppers 80% larger, but they look a bit strange. They are fatter than the Erjingtiao peppers in later generations of Shu.

The fruit hangs down and has four heads at the bottom. These are somewhat similar to vegetable peppers, but although the spiciness is much lower than that of the original species and diploid, it is spicier than later generations of vegetable peppers, which is very suitable for the taste of the people of the Song Dynasty.

The green peppers in this season are the best for making roasted pepper and eggplant.

The water spinach and sweet potato leaf tips on Zhuangzi are also at their fattest and tenderest, and the sweet potato vines serve as excellent green fodder and are eaten by humans, pigs, and chickens and ducks.

Water spinach is aquatic. A puddle has been opened by the lake. Fermented chicken and duck manure is used as the base fertilizer. It grows much better than other farms and is more tender.
