If you want to start the internal combustion engine, you need to have an external force to drive the crankshaft to rotate, so that the internal combustion engine can rotate first, as long as the first power stroke, the internal combustion engine can drive itself to rotate, and the start is successful.

The crank start is to make the crankshaft rotate, the cable start is to make the crankshaft rotate, and the electric start is to make the crankshaft rotate, but the external force is different.

In the past, the old liberation was to start by pedaling, as soon as the foot pedal was stepped on, the starting motor was pushed to the flywheel ring gear ring, driving the gear ring to rotate, and later most vehicles were screwed with keys, and there was a throwing wheel on the starting motor shaft, which was combined with the gear ring, and then drove the gear ring to rotate.

If the engine is larger, the starter motor may be underpowered, and there will be an internal combustion engine to start the internal combustion engine, starting the small gasoline engine of the two-stroke first, and then using the gasoline engine to start the diesel engine.

In addition to these, there is also compressed air start, common tanks, in winter when the battery is low, on the compressed air.

The people present were all insiders and had seen all kinds of starting methods, but when they saw Xing Fuqiang take out something similar to a diamond shape and install it on the partial cover on the outside of the diesel engine, they all widened their eyes with curiosity.

What is it?

Da Zhuang's eyes were also suspicious.

Although young, but Da Zhuang is not stupid, just now he and the captain of the test team Luo Guangrong sang and harmonized, just to create obstacles to the test run of Pingwang brand trucks, because Luo Guangrong had received a call yesterday, and he could be promoted if he did this well, but he must do it in a bright and bright way, and he could not let people see that he was deliberately embarrassed.

As a truck, you can't continue to use the crank, this stubble is very good, I thought I could stump the other party at once, but I didn't expect the other party to be prepared.

The device was quickly installed, and Xing Fuqiang began to press the handle on one side of the device, and there was a rattling sound inside, just like the sound of a table clock tightening its clockwork.

Elder Yang was full of interest: "Mr. Qin, what kind of starting device are you doing?" How do I hear the sound of clockwork? ”

"Yang Lao, this is the clockwork start, which is the first initiative of our Pingwang Motorcycle Factory, and it will definitely become the best starting method for this single-cylinder engine in the future." Qin Feng introduced: "The common electric start method will be greatly limited in winter, and if you start it several times in a row, the battery will be over-discharged and lose its ability to start, while our clockwork start, with a simple structure and low cost, can also be started many times." ”

As he spoke, Xing Fuqiang had already pressed the clockwork, and then pulled the handle, and in an instant, the energy of the clockwork was released, driving the original crank to rotate, and puffs of black smoke came out of the exhaust pipe of the diesel engine, and then, a roaring sound came.

Since it was originally a hot car, it was easy to start.

Liang Feng's eyes widened: "Mr. Qin, you have a good way to start!" Our tractors can also be fitted! ”

Qin Feng spoke: "Director Liang, if you have a demand, we will directly give you the design drawing of this kind of clockwork starting device, and you can produce it yourself." ”

Qin Feng didn't plan to take it out at first, but he had this concern, this era doesn't talk about any intellectual property rights, many township enterprises, and even large machinery factories, are worried about the project, if this kind of clockwork starter appears on the market, it will definitely attract the attention of a large group of people, this thing has no technical content, it is just a bundle of clockwork and a few gears, it is easy to be imitated.

Anyway, it has to be imitated, it is better to take it out generously and drag it, they have decided to order their own twenty horsepower diesel engines, and the monthly order can have 3,000 units, and it is normal for them to be given away even if this clockwork starts.

Liang Feng shook his head: "No, Mr. Qin, we have to buy it, now it is a market economy, this thing was invented by you, we can't ask for it in vain." ”

"Team Luo, I remember that after our second automobile came out with 130 trucks, as long as the automobile factories across the country took the letter of introduction, they could come and get the design drawings for free, and sent out hundreds of copies before and after, right?" Da Zhuang spoke again.

"Yes, back then, we were a family of workers across the country. However, what we are engaged in now is a market economy and a competitive relationship, and we can't just give it away. Luo Guangrong said: "I taught the apprentice to starve to death of the master." ”

Listening to the words of the two, Qin Feng smiled: "That's right, it's a market economy now, and the one that can only be given away for nothing can only be a state-owned enterprise, after all, there is a national backing, and our private enterprises have to find a way to climb up by themselves, and if they don't do well, they will fall down." This clockwork starter can't be given for nothing, you can buy it for a dollar. ”

Yang Lao let out a hearty laugh: "That's right, one dollar, that's a good point, you have to collect money, one dollar, haha." ”

Luo Guangrong's face was a little red, he quietly glanced at President Fu, President Fu didn't look at him, and was complimenting Yang Lao: "Yes, one dollar, high wind and bright festival, not only adapts to the market economy, but also embodies brotherhood, Mr. Qin is really doing great things!" ”

Liang Feng thought for a while: "Mr. Qin, let's still produce it, our factory can't be busy, when we purchase diesel engines, just give one-third of them this kind of clockwork starter." ”

Mr. Qin's high wind and bright festival, can we take advantage of Mr. Qin? Of course not! Let's just purchase it directly!

This conversation seemed to be back to the era when the whole country was united, and it was happy.

At this time, the Pingwang truck has already driven into the test site, running in a variety of different simulated road conditions, puffs of black smoke keep coming out, the car sometimes accelerates, sometimes brakes, looks pleasing to the eye.

"I'm afraid this car isn't fast, right?" Da Zhuang found something wrong again.

Torque determines load and climbing, and horsepower determines speed, which is the basic principle of physics.

A four-stroke 125 motorcycle can also put out about ten horsepower, but it definitely can't pull a ton or two of cargo like a ten-horsepower tractor, because the torque is not enough, but it definitely runs faster than a tractor.

The chassis of the Pingwang truck is the old liberation change, and now it uses a 20-horsepower single-cylinder diesel engine with a lot of torque, so it can load more than a dozen tons of goods to climb mountains and mountains, but if it is on the flat road than the speed, it will definitely not run the 90-horsepower old liberation gasoline engine.

"What's the use of high speed, for the transportation industry, the important thing is to be able to pull the weight, not how fast it can run." Qin Feng glanced at Da Zhuang: "The motorcycle runs fast, how many goods can it pull?" Besides, Lao Jiefang didn't run very fast. At most, the empty car speed is higher, and if it is loaded with goods, it may not be as fast as our car. ”

Lao Jiefang has five gears, hung to the highest gear, the throttle to the end, but it is only 75 kilometers per hour speed, but this speed is run out of the empty car, if the goods are loaded, the gasoline engine torque is insufficient, not to mention the fifth gear, it is not easy to hang to the fourth gear, and it is still a snail to climb when encountering uphill.

"Mr. Qin, now you can't compare Lao Jiefang." Luo Guangrong said: "Lao Jiefang is a gasoline engine, the power is too weak, now, a new generation of trucks have begun to popularize diesel engines, whether it is FAW 141, or FAW 140, there are diesel versions, our capital second automobile production BJ136, also with diesel engine, full power, torque, after loading the goods still run fast." ”

BJ136 is the introduction of Isuzu cab and engine modification, this kind of car in October this year trial production of three, was named BJ136, and so on a few years later, the implementation of the new national standard, the name became BJ1041.

With the engine of Isuzu, the capital second automobile is very excited from top to bottom, and feels that although this car is a light truck, the performance has long surpassed that of the old liberation, and now in front of so many leaders, Luo Guangrong couldn't help but boast.

Qin Feng sighed in his heart, it seems that Director Ma is indeed being hollowed out, and he is not happy to do it here, until now, Director Ma is like an outsider, standing aside like a guest, but the people in the test site are chattering here.

The more this guy is bullied, the more he wants to fight back, so he will definitely support himself.

"Okay, in that case, let's compare?" Qin Feng said: "Let's load and compare with each other." ”

"Let's take a look at the strength of our new BJ136." Luo Guangrong said.

"Ahem, Captain Luo, this time the leaders and peers came to see the Pingwang truck, and our second automobile is just providing a test site." Director Ma spoke for the first time.

"Director Ma, since the brother unit is here, we have to play with them, Da Zhuang, what are you doing in a daze, drive our BJ136 over!"

"Yes."

Director Ma's face was ugly, in front of so many leaders and peers, these people under his command didn't give him the slightest face! He, the factory director, can't convey the order at all! No one listened to him!

"Captain Luo, since Director Ma spoke, let's forget it, don't compare. It's not good to wreck your car. ”

"What are you kidding, our car is island technology, how can it be broken." Luo Guangrong said: "Are you afraid that your car will break? ”

"Our car is broken, we are responsible for ourselves, your car is broken..."

"Then we're responsible!" Luo Guangrong said.

"Who are you? Director Ma doesn't agree with our competition. ”

Director Ma's face was serious: "As the factory director, I don't agree with this kind of competition, the BJ136 sample car is the hard work of our factory, and it can't be broken in this inexplicable competition." ”

Luo Guangrong looked at Director Ma with a smile on his face: "Director Ma, this is to win glory for our factory, if the car is broken, I will be responsible!" Mr. Qin, how do you compare? ”

"It's not interesting in this test site, let's compare tug-of-war, but I said it just now, if your car is broken, your Captain Luo will repair it out of his own pocket, don't let us go."

Tug of war?

Luo Guangrong's eyes rolled: "Okay, tug-of-war is tug-of-war, our car is an island product, and the tug-of-war will definitely not lose to you!" ”

Yang Lao also smiled: "Come here today, you can still watch the truck tug-of-war, this is a new thing, we have to take a good look, you all behave well!" ”

Qin Feng glanced at Yang Lao gratefully, with Yang Lao's words, they should do their best, and then...

"Director Ma, help in the factory and load ten tons of goods into our car." Qin Feng looked at Director Ma.

"Let's go, go to our scrap workshop, there's an electromagnet crane over there." Another leader of the factory spoke up and ignored Director Ma.

Ten minutes later.

Pingwang truck loaded a truckload of goods.

Compared with the sand and gravel, this car is only loaded to the height of the original old liberation wooden steeplechase, but this is all scrap iron, look at the 900 tires and the ground contact parts have become flat, and then look at the hanging steel plate has been flat, you know that this car is definitely overweight.

The diesel engine in front of it hummed and snorted, and puffs of black smoke kept coming out, and finally drove back to the test site.

BJ136 also drove over, and it was also loaded: one by one, the big bags looked bulging, higher than the roof of the cab!

But the BJ136 drove easily, the engine was crisp and pleasant, and the exhaust pipe did not emit any black smoke at all.

"Leaders, our BJ136 light truck uses the 4JB1 diesel engine of Isuzu light truck, with a power of 57 kilowatts, which is not much lower than that of the old liberation, but it is quite fuel-efficient, and it is used in our car to reduce our fuel consumption by one-third." Director Ma looked at the car and introduced a few words.

In this era, there are not many advanced engines, the introduction of Isuzu's 4JB1 diesel engine, has great significance, after all, this is the latest diesel engine developed by the island country in 85 years, only two years of work, it was sent to the East.

When it comes to technology, it really can only be obtained from the hands of island countries.

In the early years, various car companies made cars, especially private enterprises, starting from scratch, almost all of Mitsubishi's 4G63 gasoline engines, which occupied almost half of the sky in passenger cars, and in the field of commercial vehicles, Isuzu's 4JB1 diesel engine was brilliant for 30 years, and all kinds of 493 engines were its relatives.

The current diesel engine is still an ordinary naturally aspirated engine, with a power of only 57 kilowatts, but it is durable, fuel-efficient, and the best engine for light trucks.

"That's right, don't look at our car is a light truck, and we won't lose the tug-of-war competition, all leaders." Luo Guangrong came out again to steal the limelight.

Other middle-level cadres of the Second Automobile frequently gave Luo Guangrong a look, and some even secretly stretched out their thumbs, so they had to show off on this occasion! Luo Guangrong is just the captain of the test team anyway, and the director of the horse factory can still meet him?

"You are spring and snow, and we are the people of Xialiba." Qin Feng said: "Now, let's compare and see, whether it is the foreign monk who can chant the scriptures, or the children of your own family who are the most competitive, by the way, Captain Luo, if the car is broken, you will pay for it out of your own pocket, right?" Just now, Director Ma made it clear that he did not agree with this competition. ”

"Of course, I don't affect the factory, although I want to win glory for the factory..."

Yang Lao looked at it with a smile from the side, this Luo Guangrong seems to be unlucky, if he doesn't respect the leader, he should educate and educate well.

"Everybody stand back." Qin Feng commanded everyone, this tug-of-war competition is dangerous, in case the steel cable is broken and thrown out, it will be a steel whip, and everywhere it goes, it will be destroyed and withered.

Lao Jiefang originally had the need for a trailer, so there was a special tow hook in the center of the rear of the frame, but the 130 was a light truck, and there was no special towing hook at the back.

"Captain Luo, where are you hanging the steel cable?"

"Back bridge, just go around the back bridge!"

So, the steel cable for tug-of-war was hung on the rear bridge, and everything was ready.

At this time, the whistling north wind also stopped, as if waiting to see this good show.

The crisp Isuzu engine, the sudden sound of the single-cylinder engine, resounded on the flat ground of the test field, the two cars were butt-to-butt, as long as the front of the car drove forward, the steel cable could be straightened, and then the tug-of-war competition.

At the beginning, different situations were revealed on both sides: the speed of the Pingwang truck was very slow, like a snail crawling, the engine was constantly emitting black smoke, like an asthmatic old man, and the BJ136 was extremely brisk, swishing forward, and the entire steel cable was almost stretched by it.

When the steel cable is unfolded, the tug-of-war enters the stage of competition.

For light trucks, it is obviously intended to rely on this impact to lay an advantage in one fell swoop, in the regular tug-of-war competition to shout slogans, and the people under them pull back together according to the slogan to form an impact, so as to better defeat the opponent.

Boom! The steel cable was completely straightened and began to be stressed, and at this moment, the light truck, which was still very brisk just now, suddenly seemed to hit the wall, and it was pulled all at once!

The engine was not calm, black smoke began to emit, the tires rubbed against the ground, making a squeaking sound, black tire marks appeared on the ground, although the car was already doing its best, but could not continue to move forward, on the contrary, officially began to retreat!

Not only the tires were rubbing against the ground, but the clutch was also rubbing, and it was already smelling burnt.

Looking at the other side, the single-cylinder engine of the Pingwang truck is still emitting black smoke, as if it will suffocate at any time, but the car is moving forward slowly and vigorously, without being affected by the steel cable behind it, and the soft tires are firmly turning forward, one centimeter, two centimeters...

"No way, this can't be!" Luo Guangrong's eyes widened and he shouted loudly.

What's impossible, this is just the basic principle of physics, Luo Guangrong doesn't understand.

Tug-of-war, who has the most strength and who wins? Of course not! Whoever has the most friction with the ground wins! Generally speaking, the fat man is heavier, the pressure is high, and the friction is greater, giving people a feeling that the fat man is strong, put on a pair of roller skates for the fat man, and see if he can win the opponent?

When the other party agreed to the tug-of-war competition, it had already lost, when they loaded more goods on the Pingwang truck, it was even more completely lost, now even if the Pingwang truck does not move, the light truck can not be pulled, not to mention the goods Pingwang truck is using the lowest gear, slowly and firmly driving forward!

Light Kali, Da Zhuang is in a hurry, absolutely not, it can't be like this!

What to do?

It was useless to continue to step on the accelerator, so Da Zhuang's heart was horizontal, with both feet together, the left foot clutched, the right foot braked, and the brake was stepped on fiercely, so that although you can't win, at least you won't lose!

The black smoke of the single-cylinder engine is thicker! It seemed that it would not be able to catch its breath the next moment, but it was still moving forward firmly, dragging the steel cable behind it, moving centimeter by centimeter.

Boom!

Suddenly, a strange sound sounded, and with this sound, the single-cylinder engine suddenly relaxed and jumped forward happily.

"No!" Luo Guangrong let out an exclamation, his eyes widened like copper bells, and he looked at the light truck.

The rear axle of the light truck was broken! With a bang, the frame slammed down, the rear butt of the entire light truck collapsed, and the front of the car also rose up, and when the frame touched the ground, there was a sound of steel twisting inside.

The whole frame is bent!

Change the axle, change the frame, this tug-of-war competition will lose at least tens of thousands of dollars! How much is Luo Guangrong's salary? Luo Guangrong's mind was empty, and only one voice was echoing, it's over, it's completely over!

Director Ma was expressionless on the side, and took advantage of this opportunity to set a fire!
