Chapter 114 Done, call it a day
"Let's communicate about the 213 engine first, and then discuss the compatibility issue."
After Fang thought it through, he put what had just happened out of his mind.
I started talking to Mr. Wang about the problem at hand.
The two chatted while drawing graphs and recording data.
“In theory, it’s fine.
Moreover, the parameters of the 213 engine are much improved compared to those of the 680Q engine.
The 680Q is L6, with a displacement of 2.2, 90 horsepower, 66kw power, and the current test result of fuel consumption is 14 liters.
The 213 is L4, with a displacement of 2.0, 101 horsepower, 75KW power, and a fuel consumption of 11-12 liters.
Obviously, the 213 engine is much better in every aspect.
The weight of 213 is 1495kg, and the weight of 760 is 1455kg.
So for the time being, there is no need to increase the powertrain from L4 to L6.
From the perspective of the power system, 101 horsepower is more than enough, even more than enough.
It's the gearbox and engine that need adjustment.
First of all, the engine of 213 is designed with low torque and high torque. 213 is a jeep, so there is no problem in using it.
But the 760 is a sedan, and too much low-end torque would be a bit inappropriate.
Moreover, the usage environment and road conditions of the two are completely different.
In this way, I adjusted the design of the 213 engine.
Then, is there anyone in our factory who can adjust the gearbox?"
Fang Xiang made a summary at the end.
“Yes, but the technical level is average.
Moreover, the current prototype car uses a manual three-speed mechanical transmission that we designed and developed ourselves.
Judging from the current usage, it is quite stable and reliable.
So do we need to change to a 213 manual four-speed?
After all, we don’t know much about the 213’s gearbox…”
Mr. Wang nodded, agreeing with Fang Xiang's summary.
At the same time, a question was also raised.
"Try them all and use whichever one works best."
Fang Xiang’s idea was very simple, although he was the designer of the 213 gearbox.
But after all, the 213 is still in the road test stage and has not been compared with the 760 sedan.
There is no intuitive comparison between the two in terms of cost, durability, and reliability.
Since people are already here, we might as well take this opportunity to build it and see for ourselves.
It’s just a matter of installing a few gearboxes on the car. Isn’t it a piece of cake for Shanghai Auto?
Soon, before Director Zhao came back, Fang Xiang had finalized the plan.
“There are a few questions regarding the 680Q engine.
One is frequent detonation, which can easily lead to cylinder gasket failure.
In addition, throttle failure, idle control valve or circuit failure may occasionally occur.
As well as abnormal vibration, carbon deposits, oil leakage, oil burning and abnormal noise. "
As Mr. Wang spoke, he observed Fang Xiang's expression.
"Knocking is caused by the compression ratio being too high, the gasoline not meeting the standards, and there is also a high probability that there is a problem with the fuel injector.
The other problems are not serious either, they are all issues of design and processing accuracy.
Since the parameters of 680Q are very backward now, don’t consider it for now.
After the new engine is installed on the car, we will test it on the road. If it really doesn’t work, we will make another decision.”
Fang Xiang was stunned for a moment. Why did they mention 680Q?
There are already such good products, why are you still holding on to this outdated and unusable 680Q?
Are you reluctant to give it up? Or do you want to test your own level? Or do you have other ideas?
But let’s not worry about that for now, there is the 213 engine available.
The 680Q, which is ten years behind the times, can basically be declared retired.
After the discussion, Fang Xiang followed Director Ma to the guesthouse.
It is a luxurious suite with good decoration.
There's even air conditioning.
After Director Ma left, Fang Xiang stayed there temporarily.
Until the engine drawings arrive, there is basically nothing I can do.
Not long after Director Ma left, Director Zhao recruited Engineer Wang.
Ask about what Fang wants to do.
However, Fang Xiang didn't know all this, and even if he knew, he wouldn't care.
After Fang Xiang adjusted the low torque of the 213 engine, Director Ma arranged a guide and a vehicle.
I visited Shanghai, Suzhou and Hangzhou.
I also bought a few sets of Mao suits and leather shoes for spring and summer.
Shanghai’s famous pear paste candy, five-spice beans, Gaoqiao pancakes, sesame candy, cowhide candy, lard paste and White Rabbit.
Suzhou City has Suzhou-style pastries, embroidery, and Biluochun tea.
As well as the lotus cakes, Dingsheng cakes, West Lake lotus root starch, silk, pickled duck and Longjing tea from Hangzhou Zhiweiguan.
It can be considered a gift that I can give away when I return home.
After one circle, the space was almost filled with these things.
When in Hangzhou, Fang Xiang went out of his way to try the nationally famous West Lake Vinegar Fish.
It has to be said that Hangzhou deserves its reputation as a food desert.
This West Lake vinegar fish can almost be compared with the old Beijing soy milk.
While Fang was enjoying himself, the blueprints sent from the capital arrived.
Shanghai Auto immediately started work according to the drawings.
After a few days of overtime.
The cooperating internal combustion engine factory and machinery factory produced several samples of engines and clutches.
After being transported to Shanghai Automobile, the engine was successfully ignited and loading began.
After a day and a night of overtime, three prototypes rolled off the production line.
Start the new car and do a road test.
More than 20 drivers worked non-stop for three days without any sleep, and there were no mechanical failures.
The performance of various data also made Shanghai Automobile very satisfied.
At this time, ten days had passed since Fang thought of going to the Shanghai Stock Exchange.
"Well, any questions?"
Fang Xiang stood in front of SH760 and shook hands with Director Zhao.
“No problem, no problem!
I didn't expect that Comrade Fang would solve our big problem as soon as he arrived.
Thank you so much.”
Director Zhao was also in a good mood at this time. He held Fang Xiang's hands and shook them continuously.
“As long as you are satisfied, if there is nothing else, I will go back to the capital.
If you have any further questions, you can talk to Professor Xu. "
Fang Xiang looked at the people watching and thought that he could finally go back.
"Don't worry, let's listen to our acquaintances at FAW.
You have made a lot of internal improvements to the new Hongqi, and they are all amazing.
I wonder if it would be convenient for you to help us improve it as well?"
Director Zhao looked at Fang Xiang and thought of the news he had learned from FAW before.
Thinking that Fang Xiang hadn't left yet, I might as well give it a try.
“That would cost a lot of money.
Moreover, red flags are used by leaders and for receiving foreign guests, so there is no need to be afraid of spending money.
But SH760 is not, aren't you satisfied?"
When Fang Xiang heard this, he thought it was actually not a big deal.
But when I thought about the earthquake in the Ministry of Machine Building, I suddenly had a headache.
"Please give us your suggestions. We can make improvements based on cost and demand.
What do you think? "
Director Yang's attitude was very sincere.
"Okay, then I'll draw some and you can choose from them."
Fang Xiang pondered for a moment, then nodded and agreed.
Therefore, the interior design previously drawn at Hongqi was improved.
I picked and chose some that can be used on SH760.
I also drew some.
This makes the interior of the SH760 look more comfortable and practical.
Finally, Fang Xiang was inspired by the painting.
Even the appearance has been improved.
“The current appearance is basically based on the 180S.
All of them are design elements from the 50s.
Looking at it now, it cannot be said to be outdated, but at least it does not feel trendy.
I have drawn a more avant-garde design for you that is in line with today's world trends.
You can try building a shell.
If possible, it can be sold as a high-end configuration together with those interior improvements.
This way, maybe I can make a little more money.”
After finishing drawing the blueprint, Fang Xiang did not forget to give some instructions.
The so-called low-profile and high-profile concepts of later generations were also brought up.
As for whether Shanghai Auto sells it as a high-end or low-end model, or as two models.
That's their own business.
"Great, this design... is really incredible!"
Director Yang and Engineer Wang looked at the drawings and expressed admiration from the bottom of their hearts.
After all, it is a design from later generations.
For people of this era, it is still very shocking.
After finishing the work at Shanghai Automobile, Children's Day was approaching.
Fang Xiang had not yet had time to embark on the journey back to Beijing.
A phone call from Beijing interrupted his trip.
"Xiao Fang, this is the Changcheng Aircraft Manufacturing Plant in Gan Province.
There is a prototype that will be tested the day after tomorrow, you can go and take a look."
