reborn industrial empire

Such debates and disagreements will actually occur in the research center of any automobile company. When faced with the same problem, many engineers will have different opinions.

These opinions often become an important direction for a company's future development. If errors occur in repeated interpretations, the company will enter the misunderstanding of research and development, which will bring immeasurable consequences to the company.[bsp; For Mr. Liu Hong , and Li Huijunal’s views, Jin Xiaoqiang has already reached a conclusion in his mind.

Li Huijunming's point of view is correct. The future direction of automobile development is small displacement, large diameter, energy saving and emission reduction, and Mr. Liu's idea is also correct. If you want to become a real leader in heavy industry, then The company cannot just study engines for small-displacement cars, it should invest a certain amount of resources and manpower into heavy-duty research.

This kind of diversified business operation can minimize the profitability and operational risks that a company will face when it becomes bigger and stronger.

After all, if you only work on one end, then it is impossible to make the company bigger and stronger. If you are in this industry and cannot generate enough profits due to the influence of certain factors, then the company will face profitability difficulties. , or even the risk of losing money and going bankrupt, so diversified operations are the only way for the company to develop in the future.

In fact, in Jin Xiaoqiang's view, the views of Mr. Liu and Li Qilu were both correct. It was just that the two were friends and were too serious, which led to such a situation.

The teaching car that he is about to express his passion for is launched as the company's future mid-to-high-end product. Now that he has given this car a beautiful appearance, he must give it a strong heart.

As for mid-to-high-end models, if you don’t have more than a large-displacement engine, that won’t work! This is the conclusion!

With the development of engines to this day, everyone has reached consensus on many things, such as the relationship between the displacement of a car engine and the number of cylinders. Engines with a liter or less are generally 4-cylinder, engines with a liter of 6 or more are generally 6-cylinder, and engines with a liter or above are mostly It adopts the design of vc or even v port. But is it better to use 4 cylinders or 6 cylinders for the 10,000-liter Zuogu machine? This question is worth exploring.

As far as the 10,000-liter sedan engine is concerned, the current development trend is indeed that in-line 4-cylinder engines are more popular than V-type 6-cylinder engines. Because for family cars, economy and reliability are always the highest priority. Back to back switching performance.

The maximum power speed of the heavy-duty truck's hybrid engine is less than 2000pm

The engine of a high-performance sports car can be pulled to more than 7000pm. Both are considered high-speed engines. Why? Because the standard used by engine engineers to distinguish between high-speed and low-speed engines is the average operating speed of the car, not the rotation speed. This... indicator is better than that of the engine. The speed can better measure the copying level of the machine.

Since the bore and stroke of the inline microcomputer are larger than the V-type 6-cylinder engine of the same displacement, its speed is lower under the same load. For example, the stroke of the Mazda Ruiyi's 4-cylinder 2.5-liter VZR gap engine is older~ ~~~, and the same 2.5-inch Nissan Tiansu vo25 adopts v6 design

The stroke of the piston is only an arc~~: When the average speed of the piston reaches 10

hour (generally the fuel economy is better at this speed)... The engine speed of the Mazda Ruiyi is only 3000pm, while the engine speed of the Tiansu has reached 400pm: obviously the calculation of the Mazda Ruiyi is more in line with most people's daily driving habits.

Of course, this is only for ordinary family cars and ordinary users, but what about those Gaori users?

We must know that rich people, especially those who can spend hundreds of thousands or even millions on luxury cars, do they still care about gas money?

Wrong, what they care more about is the comfort, safety, and power output performance of the car!

The V6 engine can well meet the needs of these people, with output in Beihan and Beimou, as well as the engine's stability and adaptability, as well as the speed-up performance of the vehicle, as well as noise control during the speed-up process, etc. In terms of cars using VC engines, they have obvious advantages over cars with inline 4-cylinder engines!

There is no doubt about this!

Therefore, the displacement of 10,000 can be said to be the dividing line between inline 4-cylinder and VCV6-cylinder engines. It is also the dividing line between whether a car is a family car or a Xinghua sedan!

When designing the Junxian car, Jin Xiaoqiang designed this car as the future flagship Gaorui car, so in his opinion, it is necessary to use a VC engine in the Gaorui model.

Because of the design of VC, it has an inherent advantage over in-line micros in terms of smoothness and quietness, but in terms of power, it is even more incomparable.

And for consumers who buy luxury cars, these two considerations are definitely important!

But in-line micro engines are not out of the question. Li Huijunming, because of his British philosophy, even dug into the drawings Xiaoqiang sent back and drafted a 4-cylinder eco engine:

This also just solved a problem that Jin Xiaoqiang was thinking about, that is, after all, there are two models this time. The Junxian is aimed at the mid-range, while the LaCrosse is targeted at high-end consumers. So why not separate them and have them on the market? What about the engines of Qi and VC respectively installed on the two vehicles?

Another issue about this car is the inverter it needs for power matching.

As a car designed specifically for mid-to-high-end models, its transmission is also very British, because it is also a gimmick, a rather unreasonable selling point.

Currently, the main transmissions of mid-range and high-end models on the market, such as Mercedes-Benz and Mercedes-Benz, are all six-speed manual transmissions, which have one more gear than the popular ordinary family cars on the market. Currently, mainstream family cars on the market still use five-speed automatic transmissions. You've got a manual automatic transmission, or a 4-blade automatic transmission.

Before the emergence of Huayang Power, among the self-owned brand cars produced by the park... there were no models with automatic transmission at all, and even if there were, they were only a handful.

This automatic gearbox has always been an important project for foreign car companies in its original history, and this situation will continue for five to six years before it is broken by China's own brands.

But the current manual transmission that is ready or sealed...according to the current investment and production capacity of Huayang Power, it is not a problem at all, even a 6-speed transmission is not a problem.

The original Regal and LaCrosse models produced by GM Buick used a 6-speed manual transmission, but it affected the Junxian and LaCrosse at that time and left a bad reputation for this car. It is this 6-speed manual transmission that has been criticized for a long time.

In my previous life... after SAIC-GM launched those two models, Junxian and LaCrosse, the two cars were well received in terms of appearance and power as soon as they were launched. However, the majority of consumers paid for these two models. After buying it, it didn’t take long for many consumers to raise issues such as the car’s power, slow speed, etc.

After extensive deliberation, everyone found that there was nothing wrong with the engine of this car. Perhaps it was because GM upgraded the engine's in-cylinder direct injection... But the real problem lies in the engine used in this car. This one is on top of an automated manual transmission.

It is the problem with this transmission that affects the performance and power of the entire car. So in this life, Jin Xiaoqiang copied this car and regarded it as the product packaging of Zhonggaoliu. Of course he is Won't make the same mistake again.

Originally, he wanted to directly match it to a Yijiaowan transmission, but now that he thought about it carefully, he still felt it was better not to do this.

Niu Jing's car was originally launched for users of Zhonggaorui. These people have strong spending power. They have driven many luxury cars and have their own driving experience for each car... If Huayang is left to them If Yinjia's mid-to-high-end products are not good enough, it will have a small potential impact on product promotion in the mid-to-high-end Rui market that Huayang Dynamics attaches great importance to in the future.

So after some thought, Jin Xiaoqiang decided... to take out Wei Xing's concept transmission and dual-clutch transmission a few years later.

Currently on the market, only Volkswagen has come up with the idea of ​​using a dual-clutch transmission...but it has not yet been widely promoted to all their models.

And even a few years later, after Volkswagen launched their 6-speed dual-clutch transmission, it did not succeed. Instead, because of the dual-clutch transmission problems at that time, it ended up having to recall the problem vehicles, replace the transmission, etc. question.

After future generations of consumers gained such a reputation, they once judged Volkswagen's dual-clutch inverter to be inferior. However, in Jin Xiaoqiang's view, in the future, dual-clutch inverters will still be used for some time. It has become the mainstream direction of research on transmissions, especially high-end transmissions.

In terms of fuel economy, shift response, smoothness, and its own kinetic energy loss, the dual-clutch transmission has advantages that other transmissions cannot match.

So he plans to equip his Gaori model with a dual-clutch inverter, but this time he will not choose to copy Volkswagen's failed dual-clutch dry inverter.

What he planned to copy was the Najiao 6 Younian dual-clutch transmission that was later widely promoted by Fute on many models. Although this transmission looks the same as Volkswagen's dual-clutch transmission, it is in terms of safety and reliability. Compared with Volkswagen's PSG, it has the advantage of being tested in the market, so this transmission has entered Jin Xiaoqiang's sight. However, as a wet transmission, this transmission also has traditional shortcomings, because the transmission The tank requires special cooling liquid for cooling and lubrication, so its own energy consumption is relatively large, and the boiling energy generated is also relatively large, among other problems.

Jin Xiaoqiang, an investment accountant who has been recommending and copying other people's products, this time he plans to copy this transmission and at the same time see if he can use this transmission to reduce the heat dissipation problem.

Good problems will be solved.

After the frequency leasing meeting with the engineers in Nanyang that day, Jin Xiaoqiang already had a plan in mind, but before returning to Juncheng, he still had some things to deal with, such as the Shanyu Beer stock issue!
