Chapter 229: Redesigning the Engine
"McRaw, what do you think is the future of automotive development?"
McCraw is a veritable tech nerd, the biggest characteristic of this kind of person is that he loves to admit death, loves to be more serious, and it is often difficult to change their views, Ling Shizhe does not want to use the identity of the boss to suppress, so he decided to use the way of guidance to let him take over his own concept.
But McCraw is not stupid, obedient and obedient, when he saw the boss say this, he knew that the boss was not very satisfied with the engine he made, so he said: "Why boss, are you dissatisfied with these two engines?" ”
Seeing that he didn't come according to the rhythm he set, Ling Shizhe sighed, thought about it and changed his way, and said, "Tell me first, how much does it cost to manufacture these two all-aluminum engines?" ”
"Hmm...... One costs about $20,000. McCraw hesitated, but still reported the number.
"A car engine of 20,000 US dollars, from the perspective of various parameters, this kind of engine can only be regarded as a civilian engine, but now the manufacturing cost of such an engine is 20,000 US dollars, after installing the car, how much do you say this car should be sold for?"
"But boss, you should know that aluminum is lighter than cast iron, and this is the future development trend." McCraw said a little unconvinced.
"All-aluminum engines are the way to go, but not now." Ling Shizhe pointed to the cylinder wall of the DOHC engine next to him, "It takes time for new materials to be born to be popularized, and all-aluminum engines are not absent on the market, because the current price of aluminum alloy materials is too expensive, those supercars and luxury cars like Rolls-Royce will use all-aluminum engines, and general car engines will not be cast with aluminum alloy."
If the aluminum engine wants to be popularized on a large scale, it is difficult to popularize unless the material price is as low as that of cast iron. Moreover, the technology of aluminum alloy materials used in automobile engines is not yet mature, so do you think it is appropriate to blindly use it as a casting material for engines? ”
"I'm sorry boss, I ......" Although the technician is a little stubborn, McCraw also understands a truth. That is, after all, the product still has to serve the market and the company's profits, if it can't make money, then why should the company research new technologies?
"It's okay, just recognize it clearly." Ling Shizhe waved his hand to show that he didn't mind. "Change it back to cast iron, and remember to have a fully enclosed waterway design."
"Well, I'll change it." McCraw nodded.
These two engines were designed by McCrow's technical team in full compliance with Ling Shizhe's requirements, highlighting energy saving, reliability, durability and ease of maintenance, as well as high output power. Mitsubishi's 4G63 nose has nothing to praise except for its high output power.
The 16T engine is known for its energy saving and high cost performance, so Ling Shizhe asked McRaw's team to redesign a high-performance and cost-effective engine based on these two engines in accordance with the requirements of modularization and serialization.
This is a very mediocre engine, and the various parameters are not very good, which is suitable as the power heart of the general family car.
If you think that this engine has average performance, you are very wrong, with twin camshaft construction, DVVVVIS technology, and twin turbocharging system. As well as multi-point EFI control technology, controllable timing chain technology, these give this engine a very high power performance, and the civilian high-performance engine is its selling point.
In order to correct McRaw's mistake as soon as possible, Ling Shizhe spent the next few days in the automotive power laboratory.
First of all, the engine block was replaced with cast iron material, and the cooling channel was changed to a closed type, which was able to withstand the high pressure brought by the twin turbos. Due to the use of many new technologies in this engine, the liter power of the engine is much higher than that of the current engines on the market, which also increases the heat of the engine a lot. Cast iron does not have the good heat dissipation of aluminum, so Ling Shizhe used silicon-aluminum alloy as the cover, which not only increased the heat dissipation of the engine, but also reduced the weight of the engine.
For better heat dissipation. McCraw uses two high-pressure water pumps to increase water circulation in the engine's recirculating cooling path, as well as an increased cooling fan for the engine. In order to further reduce the weight of the engine, Ling Shizhe and McCraw technical team decided to replace the least important part of the engine, that is, the bottom of the gearbox, with silicon aluminum alloy material after many discussions.
This results in an overall weight of 10 kg less than a conventional engine. And the overall structure of the engine is also very compact, the vast majority of European and Japanese ordinary family cars on the market can be installed, if it is a mini car, just turn the engine into a three-cylinder, you can install it.
"Do the math, what is the total cost of the engine?"
An accountant came over with a financial sheet and said, "Boss, the entire engine cost is more than $10,000 to build, and the cost is mainly focused on the ECU and the precision sensor pressed on it. ”
The cost of an ECU trip computer is 3,000 US dollars, plus a variety of precision sensors and various electronic control valves, the ECU system alone is more than 4,000 US dollars, plus some parts of the engine are made of aluminum materials, and a series of new technologies such as twin turbine systems, so that the manufacturing cost of this engine exceeds 10,000 US dollars, which is completely comparable to the price of high-end engines in Europe and the United States.
"Boss, do you want to reduce the allocation?" McCraw came up and asked.
Ling Shizhe thought for a while and shook his head, and said, "No, this kind of result is something I expected, and I don't plan to put this engine on the market?" ”
"Not going to market?" McCraw was shocked, if you don't launch it on the market, then what are you doing with engines?
"Hehe," Ling Shizhe looked at McCraw and smiled, "I named this engine the XU-100, the reason I built it was to give the company technical reserves, and after this engine passed all the tests and tuning, I will use the XU-100 as the basis to launch a variety of different models and engines for different markets." ”
McCraw understood that Ling Shizhe did not have the idea of making cars, but he had plans to make high-end parts for automobiles, although he did not plan to make cars, but engine technology could not be without. Engine, transmission and chassis are the three cores of the car, if one day those European and American car predators kicked Ling Shizhe away, with these three core technologies in hand, Ling Shizhe can turn his head to support other small and medium-sized car manufacturers, or simply do it himself, this is a strategy that can be attacked, retreated, and defended.
At present, the mainstream of the world's automobiles is Europe and the United States, followed by Japan, while China does not have its own auto parts group, even if there is, they are engaged in the manufacture of low-end automotive vulnerable parts. In the case of Taiwan's Yulon Group, they do not have engines, chassis and transmissions, and these three core manufacturing technologies, like the state-owned automobile manufacturing companies in the mainland in later generations, are obtained through joint ventures with foreign auto giants.
However, this approach is very limited, because Western countries do not want to see a new competitor to compete with them in the already fierce auto market, and their cooperation with Yulon is only to occupy the market in Taiwan and Southeast Asia.
And once Ling Shizhe has conquered these three core technologies, and the automotive technology in his hands is not lower than that of Europe and the United States, do you say that Yulon Group will still be willing to be a little brother? He will definitely stand up and compete with foreign auto giants.
In his memory, the Chinese people in the previous life are scrambling to produce cars, but they ignore the vital auto parts, especially high-tech auto parts, so that whenever there is a new car launched, or at a critical moment, those international auto parts giants will not hesitate to break your goods, such as ECU, automatic transmission, etc., all of which are intuitive and important high-end spare parts.
If there is a domestic auto parts company at this time, providing them with these high-end spare parts, domestic cars will definitely be another result.
A total of 15 units of the XU-100 were built, sent to the test room and started to operate 24 hours a day, and then engineers adjusted the engine according to the data measured every day to obtain the best performance of the engine.
Data testing is quite a boring job, but it is also a very expensive job, which in the intake manifold, water cooling, exhaust and other key parts, all pretend to be accurate sensor engines, once put into operation there is no stopping.
Upstairs in the test room is the database center room, where data cables connect the two sides, and the data recorded every day is a large amount of data, which must be archived one by one, compared, and then adjusted to obtain the best data combination.
Ling Shizhe calculated, these 15 engines will continue to run day and night, and by this time next year, the engine tuning will be completed, followed by various road tests, and two years later, the XU-100 will be finalized.
After observing for a few more days, seeing that the automotive power laboratory was on the right track, Ling Shizhe left, because he didn't need himself here, and he had another job to complete, that is, the car chassis. (To be continued.) It's like a book, the house of books! Unique URL:
