Chapter 269: Transformation of Jeep
Li Yang looked at the old factories and machines outside the window, his eyes becoming more determined.
He knew that realizing his grand dream of building a car would not be achieved overnight.
But with the help of the system, everything seems to be within reach.
Back at the United Technologies Center, Li Yang couldn't wait to take out the blueprints and start conceiving the engine he had longed for.
Searching rapidly in his mind, he soon locked onto a classic inline four-cylinder engine from the 80s - Honda's ZCDOHC OHC VTECi engine.
This engine uses two camshafts and 16 valves, equipped with an electronically controlled variable valve timing and lift system.
It is simply the crystallization of the top technology of this era!
Li Yang sketched out its slender lines on the drawing and knew the structure of this engine very well.
缸径75mm,行程90mm,排量1.6L,压缩比高达惊人的11.0:1!
At 7200rpm, it can burst out a maximum power of 130Ps.
The peak torque reaches 145N·m?1?8 and the red line is as high as 8000rpm!
With such power parameters in the 60s, it was simply a beast.
Even in the 80s, it was epoch-making!
Looking at the engine cross-section view on the drawing, Li Yang's eyes became more and more passionate.
In order to build this dream engine in the 60s.
He densely wrote down a series of improvement plans in the blank spaces of the drawings:
"The cylinder body must be made of aluminum alloy, using sand casting, with a minimum wall thickness of no more than 3mm; the crankshaft must be made of forged steel, surface hardened, and equipped with high-precision bearings to withstand high-speed operation;
The connecting rods also need to be forged, with H-shaped cross-sections and high-strength bolts to ensure strength;
The piston should be made of aluminum silicon alloy and inlaid with fusible alloy to prevent overheating damage.
As for the DOHC cylinder head, it must be gravity cast with aluminum alloy, with a smooth surface, no burrs, and smooth passages;
All four camshafts are hardened and ground to a roundness of no more than 0.01mm to ensure precise meshing;
The camshaft core adopts a hollow design and is filled with sodium alloy to absorb high-frequency vibrations and reduce noise.
Li Yang wrote down a lot of design parameters and process requirements in the corners of the drawings, as if his wild imagination was about to become a reality within reach!
Li Yang is also full of imagination when it comes to chassis improvements.
Although this car is already four-wheel drive, in Li Yang's opinion, this is far from enough.
He plans to install an electronically controlled multi-plate clutch that can automatically distribute power to the front and rear axles according to road conditions to achieve intelligent four-wheel drive control.
"Both the front and rear axles must be replaced with fully floating types, and the wheel hubs must be equipped with integrated bearings. This will greatly improve transmission efficiency and reliability." Li Yang quickly marked on the diagram.
In terms of suspension, he plans to replace the original springs with a transverse double wishbone independent suspension and fill the shock absorbers with nitrogen to achieve better vibration filtering.
"The steering system should use hydraulic power assistance, the rack should be made of high-strength quenched and tempered steel, and the steering gear should be installed in the anti-collision beam to save layout space."
On this page, Li Yang wrote down the modification plan in a very eloquent manner, and his ambition to upgrade the Soviet-made jeep was obvious.
When talking about transmissions, Li Yang is even more passionate.
You know, the old 469 still uses a 3-speed manual transmission, which doesn't even have a synchronizer. Not only is the gear shifting jerky and laborious, but the transmission efficiency is also very low.
"It must be changed to 5th gear, no, 6th gear! We need to install synchronizers, hydraulic operating mechanisms, and electronically controlled actuators so that the gear shifting will be fast and stable!" Li Yang excitedly wrote down a series of requirements on the drawing.
Now, he has already outlined a wonderful blueprint in his mind.
The dream car in my mind has taken shape!
……
Soon, Li Yang implemented these improvement plans one by one and called on all departments to start implementing them.
Under his deployment, technicians from the engine factory, chassis factory, and gearbox factory took action and began to make samples and manufacture according to the drawings.
At first, everyone was confused and didn't understand what those strange things on the drawings were used for.
But after Li Yang's explanation, they suddenly understood and their eyes lit up.
"It's incredible! I didn't expect Engineer Li to be so capable and to be able to make such an awesome engine!" a technician exclaimed in amazement.
"Yes, this configuration of dual overhead camshafts and 16 valves has never been seen abroad, right?" Another engineer also praised it highly.
Everyone was talking about it, full of enthusiasm, and wanted to work all night to make this dream engine!
Everyone is also looking forward to the modification of the chassis and transmission.
An old mechanic was filled with emotion: "Four-wheel independent suspension, 6-speed automatic transmission, this is simply the technology of the future! With them, do you still have to worry about crossing the wild?"
With everyone's joint efforts, the parts of the new engine, new chassis and new gearbox were finally manufactured.
At this moment, the entire United Technologies Center was filled with jubilation.
Everyone gathered together, scrambling to look at the brand new parts, their faces filled with smiles of pride and joy.
But they don't know that these seemingly ordinary iron guys are the key puzzle pieces to compose their dream car!
But at this moment, Li Yang had no time to celebrate. He had to complete the final sprint of engine assembly in the shortest possible time!
He took off his coat and rolled up his shirt sleeves, looking ready to do something big.
"Here it comes! Cylinder!" he shouted, and the technicians immediately pushed over a silvery aluminum cylinder and placed it horizontally on the workbench.
"Main shaft!" Li Yang took the crankshaft that had already been hardened and polished, and carefully installed it into the crankcase.
With a slight click, the crankshaft is firmly in place.
"Connecting rod!" Several workers brought four silver-shining H-shaped connecting rods and handed them to Li Yang.
With the ticking sound of the socket wrench, the piston-connecting rod assemblies were installed into the cylinder one by one.
"Cylinder head! Camshaft!" Following Li Yang's instructions, the four black camshafts were put into place one by one, giving off an attractive luster on the highly polished cylinder head.
In less than two hours, a brand new engine had taken shape.
The sun shines through the skylight of the workshop, shining on this black machine, giving it an attractive metallic luster?1?8
Everyone watched with bated breath, fearing to disturb the newborn God of Machinery.
Li Yang was not moved at all and began the final inspection.
From the axial movement of the crankshaft to the meshing clearance of the valve mechanism, he checked it again and again, not allowing for even the slightest mistake.
Finally, as the last bolt was tightened, Li Yang straightened up and breathed a sigh of relief. "It's done!"
As soon as he finished speaking, the whole audience cheered loudly! Several sturdy young men couldn't help but hugged Li Yang and started jumping around! "Engineer Li! You are awesome! I will follow you!"
The moment the last bolt was tightened, the whole audience froze.
The shiny aluminum engine stood quietly on the workbench, emitting charming colors under the light.
Everyone gathered around spontaneously, staring at this unprecedented masterpiece.
"Oh my God... This is simply a work of art! How did you do it, Engineer Li?" Technical Director Sun Tie muttered to himself with shining eyes.
The engineer at the side stammered and exclaimed: "Engineer Li, you have completely overturned our understanding! I didn't expect that you, a mechanical expert, can even make an engine!"
"Isn't it? This is a revolutionary innovation! If it goes into production, our automobile industry will surely make great progress!" Another technician couldn't contain his excitement.
Li Yang looked at the group of Autobots with shining eyes, a smug smile on his face.
He looked around and said loudly: "Comrades, today is a day worth remembering! But this is just the beginning. The birth of an engine is still a long way from a complete off-road vehicle!"
"Next, we still have to overcome a series of technical difficulties such as chassis, gearbox, suspension, etc., and carry out a lot of debugging and testing work. It can be said that the most difficult days are still to come!"
"No matter how good the Soviet-made machines are, they cannot compare to our independent innovation! Only by mastering the core technology can we truly stand tall among the nations of the world!"
"From now on, let us work together to contribute our own efforts to building a modern and powerful country!"
Li Yang's passionate words echoed in the workshop.
The sonorous voice inspired everyone present.
……
Time flies, the years pass by like a shuttle.
In the blink of an eye, half a month passed.
With the concerted efforts of the United Technology Center, a brand new car is gradually taking shape.
The familiar cheetah shape has been given a new look by the designer?
The smooth lines, tough edges and corners, coupled with the star-studded military green paint, are simply amazingly handsome!
"Today I can finally see the true appearance of the 'dream car'!" Sun Tie rubbed his hands excitedly, his eyes shining.
"Yes, three months of hard work have paid off! We are finally going to make history!" The technician at the side could not contain his excitement.
When the last assembly part was installed on the frame, a brand new military jeep finally revealed its majestic appearance!
The familiar cheetah silhouette has been given a new look by the designer, with smooth lines, sharp edges and corners, and a star-studded military green paint, which is so handsome that you can't take your eyes off it!
With a loud bang, the engine ignited successfully!
The roar that sounded like the sound of hell set off a thunderous cheer from the entire audience!
泪水模糊了李阳的眼眶,但他强忍着,缓缓踩下油门?1?8?1?8?1?8
140,160,180...
The speed of the car keeps rising, but the chassis does not shake at all, it is as stable as a mountain!
Li Yang made a sharp turn, and the jeep shot out like an arrow, drawing a perfect arc on the track!
