Chapter 100: EA888

readx;? Li Fanyu's current mood is like breaking into the world of martial arts. Pen ~ fun ~ Pavilion www.biquge.info stepped on a banana peel on the cliff and fell, and then when he fell half dead at the bottom of the cliff, an old man with a cheat book appeared.

Boy, I have here the drawings of the third-generation EA888 turbo engine. In the future, the responsibility of maintaining world peace and raising the Chinese national car will be handed over to you!

Ecstatic, he pulled out the A4 paper from the printer, picked up the pencil and began to reproduce the drawings that had been deeply engraved in his mind.

The drawings of these six parts alone are already outrageous. But fortunately, Li Fanyu had worked hard in drawing before, and his foundation was quite solid. He turned on the lamp on the table and drew one by one.

The wall clock on the wall ticked and ticked, and it wasn't until it was dark outside the window that he finished drawing the cylinder part.

Putting down the pencil, Li Fanyu got up.

It was terrible to be numb after sitting for too long, and he stretched his waist and rubbed his aching shoulders to the office window. It was pitch black outside, and it looked like the company's employees had already left work.

At this moment, someone knocked on the door: "Brother, are you there?"

Li Fanyu was startled by the sudden knock on the door, and quickly turned around and opened the door and invited An Ning in.

"What time is it, why haven't you gone back yet?" An Ning looked at Li Fanyu's bloodshot eyes and asked with some concern.

It turned out that Li Fanyu's painting had been painted for more than six hours, and it was already more than nine o'clock in the evening.

After getting the xapp, Li Fanyu made up his mind that he couldn't let anyone know about this mysterious thing. If it is revealed, he will definitely be in big trouble. So even his parents were silent about xapp's affairs and didn't say a word.

So even a person like him, who is not good at lying, is so practiced that when it comes to xapp, he can open his mouth and talk nonsense.

He rubbed his dry eyes and said confusedly: "There is an inspiration about the engine, I am afraid that I will forget it when I go back, so I painted it, but I forgot the time when I went inside, why haven't you gone back yet?"

An Ning relieved himself and nodded. Seeing Li Fanyu in the office late at night and not returning, I thought he was worried about the affairs of the laboratory.

She took out a wet towel from the pocket of her jacket and leaned over to wipe the corners of Li Fanyu's eyes: "The workers just left, and they are going back at this time these days." Have you drawn a sketch? Show me, sister, help you with the staff. ”

"And what about me, it's too late for you to go back this time. It's too remote here, and there are still people on the construction site. It's not safe for you to go back too late, I'll send you back in a while. ”

Li Fanyu casually took a drawing and handed it over, which happened to be the top cross-sectional drawing of the cylinder plane.

An Ning saw that he had endured until this time, and thought that he had encountered some difficulties and obstacles. I wanted to help him take a look and give some of my own opinions.

But the moment she saw the picture, she was shocked. The design in front of me can only look up, and there is no point in pointing at all.

On the anatomy diagram, the specifications and materials of the engine block have been planned in great detail, and even some details, such as the suspension position, are already very perfect.

It's not a sketch at all, it's a finished product that looks ready for production and ready to be designed!

"It's... You designed this?"

"Hey, it's a blind drawing. Li Fanyu put his hand on the back of his head and looked up at the sky.

An Ning frowned, glanced at him with slanted eyes, and said quietly: "Don't tell me the truth, are you fooling me as a chick in your school?" she picked up her pencil and dotted on the drawing.

That detailed data is really nonsense if it is said to be a blind drawing.

Li Fanyu was stared at by her resentful eyes, and felt unnatural. He scratched his ears and cheeks and smiled dryly, looking at his naΓ―ve face, and in his squinted eyes, his eyes were indeed rolling.

"Ahem, I'm actually a genius. ”

An Ning looked at him for a moment, "Okay, my genius brother. She carefully read the drawings again, and the more she looked at it, the more frightened she became. There are many links that she can't even see through.

So after An Ning was shocked in his heart under strong pressure, he turned into a **** version of a curious baby: "Your valve position is so arranged, what transmission structure do you plan to use." ”

"Well, I was going to use a rocker arm. But I felt that the crankshaft wheel would definitely conflict with the rocker arm if the cylinder block was designed like this, so I planned to add rollers to the rocker arm. ”

"What about this?"

"Where's this?"

"And this!"

...... Li Fanyu actually didn't have time to carefully understand these technologies, and with the explanation to An Ning, he himself was also exploring the technical characteristics of EA888.

For this engine, Li Fanyu can be said to be very famous before the historical process has changed.

But the reason for its fame is not its excellent performance, but its biggest and biggest drawback.

This engine was equipped with Audi A4, A6 and Volkswagen Magotan, which caused a very funny phenomenon at that time due to its large sales and high market share.

The owners of these three cars always have a bucket of engine oil in the trunk, and they have to add a little bit to every 2,000 kilometers. Therefore, EA888 is jokingly called - hybrid fuel engine.

Of course, this fuel blend does not refer to diesel and gasoline, but to engine oil and gasoline.

Regarding this point, Li Fanyu was also unclear but aware of this before. With An Ning's inquiry, Li Fanyu understood the structure of this engine little by little, and he suddenly realized and solved the problem that had bothered him before.

The biggest reason for burning engine oil comes from the simple matching!

The so-called simplified allocation is to replace or simply eliminate some high-cost links with low-cost links. to reduce costs, increase margins and pricing margins.

In the past, Li Fanyu saw changing the oil of the Audi A4L in his uncle's repair shop, so he still knows about this EA888 engine.

By comparing the EA888 in his memory with the EA888 in the current drawings, Li Fan was sad to find that the special Audi is a cheat at all!

Take A4 as an example, the standard wheelbase version imported from abroad is called A4, and the domestic wheelbase extended version is called A4L, which means long lengthened.

The drawing that Li Fanyu is redeeming now is the imported standard shaft version. Compared with the A4L engine in his memory, he found that there were several more structures.

Dual Spray System, IAGK, Boost Pressure Limiting Valve, Rotary Spool Coolant Pump.

These four items are not available on EA888, which was produced domestically in that time and space.

The dual injection system, simply put, means that the fuel system adopts the most suitable injection mode according to the condition of the engine. It sounds lofty, but to put it bluntly, it is to improve fuel economy.

IAGK stands for exhaust manifold integrated cylinder head, and the manifold is the exhaust channel for the waste generated after combustion in the engine cylinder body. The layout of the IAKG uses the coolant in the cylinder head to cool the manifold by the way.

As for the boost pressure limiting valve, it controls the turbine pressure and protects the engine throttle.

Rotary valve coolant pumps are also designed to provide better heat dissipation.

Li Fanyu can understand that the double spray system has been castrated; after all, the national conditions are like this, and the domestic oil quality is not good. Having this stuff may be fuel-efficient, but it also requires a higher quality of gasoline. Originally, you could have added 93 gasoline, but with this you have to add 97. The amount of fuel saved may not be able to make up for the difference between the two gasoline grades.

But IAGK, the pressure limiting valve and the rotary valve coolant pump are castrated, which is especially taking the Chinese people as the big head!

Turbine engines are more complex in structure, and their turbine bearings and lubrication parts to keep the vacuum pump running, all of which determine that they consume more oil than naturally aspirated engines.

Moreover, the extra high temperature brought about by the supercharging will inevitably lead to the deterioration of the oil in the engine and the decrease in viscosity, resulting in the phenomenon of burning the engine oil.

Castrate all three of these three pieces, and if you don't burn the oil, you'll hell!

Li Fanyu patted his chest that was a little stuffy, he meowed, fortunately the X space exchange is an uncastrated version, otherwise if Ming'er is really listed, he will not let people spray to death!

Audi, you deserve that this time and space is a lamp factory!
