A small team of nine people quietly appeared in Nan Da Wan, and Wan Feng received them.
Lei Heyang is the leader of this team. As for where they come from, it is a secret.
Although Wan Feng didn't know these people, it was obvious that they all knew him and were very friendly to him.
They came for the variable geometry turbocharger.
When they heard from Zhu Guoxiong that a domestic company had developed a supercharger that could increase the power of a diesel engine by 40%, they immediately formed a team and rushed over overnight.
Among these people are experts in automotive and marine engines.
Fortunately, the plane does not burn diesel, otherwise there would definitely be aviation engine experts in this small team.
The most common blow-off valve turbochargers on the market can mostly increase the engine power by more than 20%, and the maximum increase is 30%.
This has reached a bottleneck, and even increasing it by one percent is unlikely to be very successful.
However, domestic companies have actually developed a supercharger that increases power by 40 percent, which is like a blessing from heaven for these engine researchers who are suffering from insufficient horsepower.
And it is said that the minimum increase is 40%, which means it would not be surprising if it exceeds 40%.
What is the concept?
This supercharger was made by Nanwan Automobile, so Wan Feng brought them to the Black Reef Development Zone.
In the engine research laboratory of the Black Lagoon Development Zone, Lei Heyang saw this new type of variable-section turbocharger.
Chi Xiaochun, the head of the invention team of this supercharger, introduced the manufacturing principle and process of this supercharger to Lei Heyang and others, and also gave an on-site demonstration.
Nanwan's ordinary 480 engine itself has a power of 30 kilowatts, which is about 40 horsepower.
On the test bench, its displayed data was only about 40.7 horsepower, but after replacing the variable-section turbocharger, the instrument showed that its power increased by 13 horsepower, which is nearly 16 horsepower.
The same is true for another ordinary 485 engine. After the original 50-horsepower engine is equipped with a variable-section turbocharger, the instrument shows that the horsepower directly exceeds 70.
Lei Heyang took a deep breath.
"Can this supercharger be used on any diesel engine?"
Chi Xiaochun wore a pair of glasses with very thick lenses, which made him look like a professor even though he was still very young.
"Yes! As long as the size of the supercharger is changed to meet the installation requirements of the engine, it is theoretically possible."
"What about some super-powerful engines?"
"That's fine. We've tested diesel engines up to 700 horsepower. With this supercharger, a 700-horsepower engine can output over 1,000 horsepower."
"You also have a 700-horsepower engine?" Lei Heyang was a little surprised. His knowledge of Nanwan was limited to what others had told him verbally, but it did not involve high-horsepower engines.
"Yes! Our V10 engine has high horsepower and low fuel consumption. It is widely used by many large ocean-going fishing vessels and small boats for various purposes."
If this engine is only equipped on five-axle and six-axle heavy trucks, it would be a waste. After all, the military does not need too many such vehicles for missile research.
Even the missiles needed now are only in the testing stage.
Nanwan developed an engine that could not be left in a semi-idle state, so it developed a civilian version.
Once launched, it became popular in the market after some shipbuilding companies learned about its performance.
Especially after the rumor spread that the original version of this engine was an authentic military product, its popularity became even greater.
Although this engine is only a monkey version and has a horsepower of about 650 horsepower, it is most commonly used in small boats that require more than 600 horsepower.
The engine, which was renamed NW Tallang last summer, received orders for 3,000 units as soon as it was launched.
When the people at Nanwan Engine saw that there was such a promising market, they subsequently developed a 1,000-horsepower V12 engine. They have now launched a project to develop diesel engines with 1,500 to 3,000 horsepower.
"Can all engines be installed?"
Chi Xiaochun hesitated for a moment: "If the strength of the engine itself meets the standards, there will be no problem. I am just worried that the strength of the engine itself does not meet its needs."
The power has been increased by nearly half, which has also correspondingly increased the requirements for the piston, connecting rod and crankshaft in the original engine.
Lei Heyang nodded. Although this problem was difficult to solve, it was still within an acceptable range.
The people led by Lei Heyang were ready to stay in Nanwan Automobile. They also brought some engine parameters and planned to produce some supercharger samples to take back for testing.
Naturally, Wan Feng couldn't stay here with them every day as he had his own things to do.
The group still has many plans waiting for him.
So he handed over the task of receiving Lei Heyang to Wen Guanghua and returned to Nandawan.
After Wan Feng returned to Nan Da Wan, he sat in the office and turned on the computer.
The computer monitor is a 17-inch flat-screen rectangular monitor that was recently replaced.
The replacement speed of monitors is also very fast. Two years ago, it was still the old 14-inch spherical CRT monitor, but now it has developed to a 17-inch flat rectangular monitor.
Some Japanese companies are now developing Trinitron displays.
However, Jingdongfang did not waste its efforts on this. Following Wan Feng's suggestion, Jingdongfang has shifted its focus to the development of liquid crystal displays.
The CRT monitor has basically completed its mission at this point. It will have no place in the future world, which will be dominated by LCD monitors. Wan Feng will certainly not let Jingdongfang take any more detours.
It is now possible to produce 14-inch TFT-LCD displays, but the cost is currently too high and not yet suitable for commercial use.
The main reasons for this are the expensive quartz substrate and low yield rate.
However, Wan Feng feels that within two years, with the recent maturity of low-temperature polycrystalline Si-TFT technology and the low costs brought by large-scale production, this type of display will appear on the market.
As for low-temperature polycrystalline Si-TFT technology, a research and development department of Huaguang Electronics has achieved quite good results and is expected to be commercialized next spring.
But in Wan Feng's eyes, he always felt that the picture clarity of LCD monitors was not as good as that of CRT monitors.
The one who should be anxious about the monitor is Jing Dongfang. He is just a shareholder, responsible for counting money while doing nothing.
Of course, Huaguang can provide any technology it has free of charge. They can be responsible for Jingdongfang's technological upgrades but will not be responsible for the progress of other people's products. That is Wang Desheng's headache.
Wan Feng opened his computer and looked at his memo. It seemed like there was nothing else to do today, so he had the leisure to open Qidian Literature Network.
There is still only his single article on Qidian.com, like a lone commander standing on a bare mountain.
Wan Feng clicked on the article and was shocked when he scrolled down.
Why are there so many comments?
