Chapter 268 Automobile Manufacturing Technology
Sun Tie was overjoyed when he heard this, and he praised repeatedly: "Engineer Li is really our benefactor! With your words, our wish will come true soon!"
Sun Tie immediately ordered his men to move out various confidential drawings and data in boxes. There were seven or eight large boxes in total, which left Li Yang stunned.
"Don't worry, Mr. Li. These are our technical department's best treasures. They are absolutely top-notch in China!" Sun Tie introduced confidently, "This turbocharged direct injection system is imported from abroad. The maximum power can reach 110 horsepower. It is absolutely first-class when used on our domestically produced cars!"
"至于这个5前进1倒退的手动变速箱,采用了多轴多档的结构,换档平顺,传动效率高?1?8比之前的4档箱,不知高到哪里去了!"
Li Yang flipped through the drawings with great interest, listened to Sun Tie's detailed introduction, and nodded secretly?1?8
I have to say, as a "mechanical geek" born in the future, these boxes of precious information are like treasures!
With an excited heart, Li Yang carefully opened the boxes of valuable automobile information.
He seemed to have opened a treasure trove of mechanical knowledge, and his eyes were suddenly filled with dazzling golden light.
The densely packed lines, formulas, and cross-sectional views on the drawings exude a mysterious and alluring atmosphere, as if calling Li Yang to come and find out.
Li Yang flipped through the pages eagerly, his eyes as sharp as torches.
He started with a general assembly drawing and took a quick look at the layout of several major assemblies, including the engine, gearbox, chassis, and body.
"Well, this is a 4-cylinder, 16-valve direct injection gasoline engine. The bore and stroke are relatively square, so it should be suitable for high-speed output. 1?8" Li Yang muttered to himself, his slender fingers moving across the drawing.
"The combination of the turbocharger and the intercooler is also very clever, which can greatly improve the intake efficiency and reduce the tendency of knocking. ?1?8" As he said this, he held up a diagram of the explosion of the injector and studied it excitedly:
"Look at the design of this solenoid valve. It can open and close quickly within 0.3 milliseconds. The atomization effect must be first-class! It is really a rare learning material!" Li Yang read the drawings one by one with great interest, and his brain was working rapidly.
[Ding, the system detects that the host is learning automotive knowledge, and activates the automotive engineer skill!]
【Current automotive theoretical knowledge is 100, and you will be awarded the title of junior automotive engineer!】
Suddenly, the familiar prompt tone of the Golden Finger System rang in his ears. Li Yang smiled knowingly and felt a force gathering in his mind. His thinking became clearer and he felt like a different person.
He re-examined the drawings, and suddenly everything became clear and boring.
"I see, isn't this a combination of direct injection and turbocharging? Although it is considered advanced at the moment, it is still far from the terrifying mechanical superchargers, twin-scrolls, and even electronic turbochargers of the future!"
"As for this 5-speed manual transmission, it has more synchronizers and the drive shaft is also segmented, but in the final analysis, it still relies on a purely mechanical structure? If it had a torque converter and a planetary gear set, it would be called a true manual transmission!"
Li Yang smiled contemptuously, with a gleam of disdain on his young and handsome face.
He flipped through all the drawings in one go, sorted them out, and stacked them neatly, then sat down contentedly?1?8
At this time, the system prompt sounded again:
[It is detected that the host has mastered the core knowledge of internal combustion engines, turbocharging, injection systems, etc. The car engine module has been unlocked!]
[Synchronously unlock the basic modules such as gearbox, chassis suspension, brake, steering, etc.! Congratulations to the host for obtaining the title of intermediate automotive engineer!]
[Grant the host advanced technology from the 60s: carburetor, synchronizer, full-time four-wheel drive, power steering, vacuum booster! Gain a lot of technical experience!]
A series of prompts made Li Yang feel like he was in spring breeze and extremely excited.
He felt that the blood in his body was boiling, and a surge of primitive power suddenly emerged in his body. Countless design parameters and technical diagrams flashed before his eyes.
Carburetor is a device that uses the Venturi tube principle to adjust the gasoline flow rate by controlling the air flow rate, thereby controlling the engine operating conditions.
Although the structure is not complicated, the requirements for precision and materials were quite high in the 60s.
The synchronizer is the essence of the manual transmission. It can synchronize the speed of the driving shaft and the driven shaft when shifting gears, thereby achieving smooth shifting and reducing impact and wear.
The high reliability of today's gearboxes is largely due to the synchronizer!
When it comes to full-time four-wheel drive, it is even more synonymous with toughness and durability.
Through a transfer case with differential, the engine torque is constantly distributed to the front and rear axles, and with the help of lower disc independent suspension, welded frame and other technologies, the vehicle's passability is so strong that it has no rivals!
This is the winning formula of the legendary off-road vehicle.
Power steering and vacuum booster also play an important role as driving aids?
They use hydraulic oil pumps and vacuum negative pressure respectively to help the driver reduce the operating force, greatly improving the control feel, especially on muddy mountain roads, which further highlights their value?
Various cutting-edge technologies appeared before his eyes, and Li Yang seemed to travel through a time tunnel and return to that passionate mechanical age.
He couldn't help rubbing his hands, and he was as excited as if he had been injected with chicken blood.
It seems as if I have seen a number of off-road vehicles speeding through the wilderness, invincible and majestic!
However, the latest prompt from the system surprised Li Yang:
[It is detected that the host has obtained the title of intermediate engineer, unlocking the 90s automobile technology!]
[Electronic control module technology has been granted, please enjoy it!]
The scene changed, and a large amount of technical information suddenly emerged in Li Yang's mind, the level of which was jaw-droppingly advanced.
The electronic control unit ECU uses chip circuits and software programs to integrate multiple control functions such as ignition, fuel injection, and emissions. It can adaptively adjust various engine parameters. Its fast response and high precision completely surpass the mechanical age!
The electronic injection technology made Li Yang even more fascinated?1?8
From L-Jetonic mechanical injection, to Mono-Jetonic single-point electronic injection, to D-Jetonic direct injection, electronic fuel injection technology is becoming more and more mature, and its efficiency and emission level have long surpassed carburetors!
Electronic suspension system ECS, active steering system AFS, electronic parking brake EPB...
A series of electronic chassis technologies emerged, and Li Yang's brain instantly turned into a huge database, storing a vast amount of cutting-edge knowledge.
He felt as if he had turned into a high-speed computer, processing various signals and parameters at the speed of light, always ready to adjust the car's performance to perfection!
Just when Li Yang was still unsatisfied and ready to continue exploring, the golden finger gave him another new surprise:
[The host has mastered the mainstream automotive technology of the 90s and successfully achieved the breakthrough of senior engineer!]
[Grant the top technology after 2000: CCVT continuously variable transmission, GDI direct injection, ISG generator, ESP body stability system... Please enjoy it! Experience points will be greatly increased!]
For a moment, Li Yang felt the world spinning and all was colorful.
Countless bizarre images flashed through his mind, making him dizzy and his mouth dry.
CCVT uses two sets of variable diameter sled pulleys to achieve infinitely variable speed from starting to any speed through stepless speed regulation! It is as smooth and fuel-efficient as CVT, but with longer life and transmission efficiency!
GDI, through a high-pressure fuel pump and precision solenoid valve, directly injects fuel into the combustion chamber, achieving a precise and controllable combustion process. Compared with external injection, it not only greatly improves power and reduces emissions, but also achieves ultra-lean combustion through stratified controllable combustion, thereby bringing the engine thermal efficiency close to the theoretical limit!
ISG integrates multiple functions such as starting, power generation, power assist, and energy recovery, and is the core of the mild hybrid system. The 1V with 8V battery can achieve frequent start-stop control and strong power assistance, bringing the fuel economy of the internal combustion engine to a whole new level!
ESP monitors the vehicle's posture in real time through sensors and actively intervenes in the braking torque of the four wheels with hydraulic actuators. It can automatically maintain the vehicle's stability under any working conditions. Even when making an emergency turn on a slippery road, there is no need to worry about the vehicle losing control and skidding, which greatly improves driving safety.
All of a sudden, a myriad of cutting-edge technologies came to him, as if opening a door to knowledge?1?8
Li Yang felt his brain buzzing, stars in his eyes, every cell in his body trembling, every nerve in his body reveling?1?8
Looking out the window, wherever you look, you can see workshops everywhere, machines roaring, a scene of bustling activity.
In Li Yang's eyes, the mottled buildings and equipment turned into colorful notes, composing wonderful hymns!
His heart surged, his blood boiled, and he wanted to rush into the workshop immediately, roll up his sleeves and get to work, and use his hands to turn those beautiful blueprints into reality!
However, reason eventually triumphed over impulse. Li Yang took a deep breath and forced himself to suppress the passion in his heart.
He knew that building a car was not an easy task. Even if he had the blueprints and the technology, it would be useless without top-notch manufacturing equipment and a professional production team.
What's more, the power of a single factory is far from enough. Engine, gearbox, body, electrical appliances... Without the coordinated development of thousands of supporting enterprises and a complete industrial chain, it is impossible to build a qualified vehicle.
Li Yang looked at the old factories and machines outside the window, his eyes becoming more determined.
