Chapter 1964 Datang's most cutting-edge technology products
Limitations in basic materials and processing have resulted in their inability to produce more horsepower in a small, lightweight single-cylinder engine while ensuring service life and controlling many problems such as failure rate, jitter, and noise.
Although such a single-cylinder engine can also be used, if it is to be widely used on a large scale, people can tolerate an engine with such severe vibration and noise, but they absolutely cannot tolerate an engine with such a high failure rate and an engine that crashes easily.
In the end, they adopted a simple and direct method. If one cylinder was not enough, they added two cylinders.
Ever since, the twin-cylinder engine appeared.
At the same time, the power output of a single cylinder is reduced while ensuring the service life and reducing vibration and noise.
In this way, even if the power of one cylinder is smaller, the combined power of the two cylinders is still large enough.
What follows is that jitter and noise are greatly reduced, and more importantly, the service life is increased and the failure rate is greatly reduced.
In recent years, due to advances in materials and processing precision, the twin-cylinder four-stroke engines produced are already pretty good. The power of the test machine mounted on the Type A car in front of us has reached 4.6 horsepower.
After tasting the sweetness of the two-cylinder engine, the gasoline engine project team of the Internal Combustion Engine Laboratory of the Royal Institute of Technology has gone on the multi-cylinder engine and has never looked back.
The two-cylinder engine has just been developed, and now it has begun to develop four-cylinder or even six-cylinder, eight-cylinder, or 12-cylinder engines.
It is worth noting that in many of the above-mentioned studies, many research funds are provided by the military, because the military has higher requirements for engine horsepower, and also has higher requirements for engine reliability and service life, which also affects the cost.
It is more sensitive, so the military is still not satisfied with the current two-cylinder engine. After all, it only has 4.6 horsepower.
Of course, this does not mean that the two-cylinder gasoline engine can only produce 4.6 horsepower, but it means that the size and weight are limited, and the engine that can be loaded on the car can achieve this level.
If we simply enlarge the volume and weight restrictions, it would be no problem to produce dozens or even hundreds of horsepower or even higher gasoline engines. However, those gasoline engines cannot be used in cars or even military tanks.
It can be used in heavy construction machinery, industry, shipbuilding and other fields.
Just like the steam engine, Datang even twenty years ago, when the high-pressure steam engine was first developed, the product line basically covered a few horses to hundreds of horsepower, but until now, Datang has not
Still can't come up with a steam chariot!
Compared with the 4.6 horsepower of the Type A car, the gasoline engine of the Xihu brand car is somewhat inferior.
The gasoline engine used in this car has a horsepower of 3.5 horsepower, which is still much worse than the gasoline engine of the Royal Institute of Technology, because the volume and weight of the gasoline engines of the two are similar.
The horsepower is so much lower, so the gap is naturally quite large.
But compared to the testing machine of the Royal Institute of Technology, Li Xuan actually values the engine developed by Hangzhou Power Machinery Company more, because the former is a purely manual laboratory product and cannot be mass-produced with the current industrial manufacturing capabilities, while the latter is
Can be industrialized and mass-produced.
Even if the yield rate is lower, the performance is worse, and the cost is higher, no matter what, it is an engine that can be mass-produced.
Only through industrial mass production can it be applied on a large scale, and can it promote the industrial production and transportation of the entire Datang Dynasty.
The biggest difference between the two cars is the engine.
The rest of the technologies used are relatively similar, such as pneumatic rubber tires, water cooling, leaf spring shock absorption, chain drive, etc.
Basically, it used many new technologies that are currently available. Although it seems very primitive to Li Xuan, for the contemporary Datang Empire, this is definitely a combination of the latest and highest technologies.
body.
Represents the highest technological content of the contemporary Datang Empire!
It is said that many of these technologies are patented by Zhongyuan Automobile Company, such as pneumatic rubber tires, which are products of a subsidiary previously acquired by Zhongyuan Automobile Company and have exclusive patents.
However, in order to obtain the patent license for gasoline engines, Zhongyuan Automobile Company was forced to reach agreements with the Royal Institute of Technology and Hangzhou Power Machinery Company on some technical products.
Moreover, these licensing agreements are actually very unfair to Zhongyuan Automobile Company.
In order to ensure the continued promotion of automobiles and related industries, expand the market for gasoline engines, and ensure the interests of the Royal Institute of Technology, the Royal Institute of Technology requires Zhongyuan Automobile Company to release the basic patent authorization of pneumatic tires to several companies, and follow the common patent authorization in the industry
Fee goes.
Of course, the patent fees still have to be paid to Zhongyuan Automobile Company. At the same time, only the most basic technical patents are required to be released. As for patents related to other tire technologies, this will not be released.
Generally speaking, it is the same as the previous four-stroke patent issued by Hangzhou Power Machinery Company.
Hangzhou Power Machinery Company is also unwilling, but has no choice.
After all, if everyone doesn't open up patents, cars won't be built.
Because no matter how crude the car in front of him seemed to Li Xuan, many of its components were high-tech products, and their patents belonged to various major companies.
In the past, when the Royal Institute of Technology authorized gasoline engine patents, it basically required major companies to come up with corresponding technical patents for licensing. It would not happen that Zhongyuan Automobile Company had obtained the gasoline engine license, but did not release the inflator.
Tire patents are granted in this case.
If you want to enter the gasoline engine related industry chain, you also need to exchange your own things and expand the market together.
As a result, even Hangzhou Power Machinery Company can use pneumatic tire technology.
However, Zhongyuan Automobile Company is already aware of this huge competitor. Although it provides basic pneumatic tire technology, it does not provide other related tire technologies. If you want, you can directly purchase their finished tires, and the price is guaranteed to be expensive.
Incomparable!
Hangzhou Power Machinery Company, while researching its own pneumatic tires, can only purchase tires from Zhongyuan Automobile Company for use first.
However, in order to prevent Zhongyuan Automobile Company from stumbling, they roundaboutly purchased the pneumatic tires through a series of leather goods companies. At first, Zhongyuan Automobile Company thought that this batch of pneumatic tires had been purchased by a horse-drawn carriage production company in Beihai Province...
It can also be seen from this that although the automobile industry has just emerged, competition is already very fierce.
